Subject: [PATCH 001/151] clk: rockchip: Set "ignore unused" for PMU M0 clocks
 on rk3399

The PMU Cortex M0 on rk3399 is intended to be used for things like
DDRFreq transitions, suspend/resume, and other things that are the
purview of ARM Trusted Firmware and not the kernel.  As such, the
kernel shouldn't be messing with the clocks.  Add CLK_IGNORE_UNUSED to
these clocks.

Without this change, the following was observed on a Chromebook with a
rk3399 (using not-yet-upstream ARM Trusted Firmware code and
not-yet-upstream kernel code based on kernel-4.4):

1. We init the clock framework.

2. We start up "DDRFreq", which causes ATF to occasionally fire up the
   M0 for transitions.  Each time ATF fires up the M0 it will turn on
   these clocks and each time it is done it will turn them off.

3. We finally get to the the part of the kernel that calls
   clk_disable_unused() and we disables the clocks.

You can see the race above.  Basically everything is fine as long as
ARM Trusted Firmware isn't starting up the M0 at exactly the same time
that the kernel is disabling unused clocks.  ...but if the race
happens then we go boom.

Subject: [PATCH 002/151] clk: sunxi-ng: gate: Support common pre-dividers

Some clock gates have a pre-divider between the source input and the
gate itself. A notable example is the HSIC 12 MHz clock found on the
A83T, which has the 24 MHz main oscillator as its input, and a /2
pre-divider.

Subject: [PATCH 003/151] clk: sunxi-ng: add Allwinner H5 CCU support for H3
 CCU driver

Allwinner H5 is a SoC that features a design which keeps the peripheral
compatible with H3, so that it have also a CCU like the one on H3 --
only one bus gate/reset is added, and the mmc sample/output phases are
removed because of MMC controller update.

Add its support in our existing H3 CCU driver.

Subject: [PATCH 004/151] clk: sunxi-ng: tighten SoC deps on explicit AllWinner
 SoCs

Tighten the depends on the various AllWinn SoCs so we don't
inadvertantly get clock drivers when we're not wanting them
like 32 bit SoC clocks for 64 bit configs. Ensure there's
still test coverage though.

Subject: [PATCH 009/151] clk: ti: add support for automatic clock alias
 generation

Large portions of the OMAP framework still depend on the support of
having clock aliases in place, so add support functions for generating
these automatically.

Subject: [PATCH 010/151] clk: ti: add API for creating aliases automatically
 for simple clock types

This API generates clock aliases automatically for simple clock types
(fixed-clock, fixed-factor-clock), so that we don't need to add the data
for these statically into tables. Shall be called from the SoC specific
clock init.

Subject: [PATCH 021/151] clk: ti: dpll44xx: fix clksel register initialization

clksel register pointer should be used for the DPLL-MX autoidle handling.
Currently this is not setup at all. Fix by adding proper handling for the
register.

Subject: [PATCH 022/151] clk: ti: convert to use proper register definition
 for all accesses

Currently, TI clock driver uses an encapsulated struct that is cast into
a void pointer to store all register addresses. This can be considered
as rather nasty hackery, and prevents from expanding the register
address field also. Instead, replace all the code to use proper struct
in place for this, which contains all the previously used data.

This patch is rather large as it is touching multiple files, but this
can't be split up as we need to avoid any boot breakage.

Subject: [PATCH 024/151] clk: rockchip: fix up rk3368 timer-ids

The timer-ids are wrong compared to the manual, probably due a simple
copy-paste mistake from the otherwise very similar rk3288. And there
are even more timers in the system than the ones wrongly listed here.

Timer-Ids were unused both in clock-driver as well as devicetree
till now, so fixing them won't break anything.

Subject: [PATCH 026/151] clk: rockchip: describe clk_gmac using the new muxgrf
 type on rk3328

With the newly introduced clk type for muxes in the grf we now can
describe some missing clocks, like the clk_gmac2io and clk_gmac2phy
that selects between clk_mac2io_src and gmac_clkin based on a bit
set in the general register files.

pll_a1 was using CLK_RST_CONTROLLER_PLLA1_MISC_0 for IDDQ control rather
than the correct register CLK_RST_CONTROLLER_PLLA1_MISC_1. Also add
pll_a1 to the set of clocks defined for Tegra210.

Return the actually achieved rate in cfg->output_rate rather than just

Subject: [PATCH 037/151] clk: tegra: Define Tegra210 DMIC sync clocks

Tegra210 has 3 DMIC inputs which can be clocked from the recovered clock
of several other audio inputs (eg. i2s0, i2s1, ...). To model this, we
add a 3 new clocks similar to the audio* clocks which handle the same
function for the I2S and SPDIF clocks.

Subject: [PATCH 038/151] clk: tegra: Fix constness for peripheral clocks

checkpatch now warns for const ** and expects const * const * to be used
instead. This means we have to update the prototypes and function
declarations to handle this change.

Subject: [PATCH 043/151] clk: tegra: Fix disable unused for clocks sharing
 enable bit

In case 2 clocks share an enable bit and one of them is enabled by a
driver and the other one is not, CCF will think it's enabled because it
will only look at the HW state. Therefore it will disable the clock and
thus also disable the other clock which was enabled. Solve this by
reading the initial state of the enable bit and incrementing the
refcount if it's set.

Subject: [PATCH 045/151] clk: tegra: Rework pll_u

In normal operation pll_u is under hardware control and has a fixed rate
of 480MHz. Hardware will turn on pll_u on whenever any of the XUSB
powerdomains is on. From a software point of view we model this is if
pll_u is always on using a fixed rate clock. However the bootloader
might or might not have configured pll_u this way. So we will check the
current state of pll_u at boot and reconfigure it if required.

There are 3 possiblities at kernel boot:
1) pll_u is under hardware control: do nothing
2) pll_u is under hardware control and enabled: enable hardware control
3) pll_u is disabled: enable pll_u and enable hardware control

In all cases we also check if UTMIPLL is under hardware control at boot
and configure it for hardware control if that is not the case.
The same is done during SC7 resume.

Thanks to Joseph Lo <josephl@nvidia.com> for bug fixes.

 order for Audio DMACs

The parent clock of the Audio DMACs is the "ZS" AXI bus clock, which
maps to S3D1 on R-Car H3 ES1.x.
All module clocks must be sorted by clock ID.

Subject: [PATCH 056/151] clk: renesas: rcar-gen3: Add workaround for PLL0/2/4
 errata on H3 ES1.0

Add a workaround for errata on R-Car H3 ES1.0, where the PLL0, PLL2, and
PLL4 clock frequencies are off by a factor of two.

Inspired by a patch by Dien Pham in the BSP.

platform. With the ongoing work on various system, including audio, this
is about to change. Use the same approach as gates for dividers and muxes,
putting them in tables to fix the register address at runtime.

Subject: [PATCH 064/151] clk: meson: mpll: add rw operation

This patch adds new callbacks to the meson-mpll driver to control
and set the pll rate. For this, we also need to add the enable bit and
sdm enable bit. The corresponding parameters are added to mpll data
structure.

Gxbb datasheet says N2 maximum value is 127 but the register field is
9 bits wide, the maximum value should 511.

Test shows value greater than 127, all the way to 511, works well

Subject: [PATCH 068/151] clk: renesas: cpg-mssr: Add support for fixing up
 clock tables

The same SoC may have different clocks and/or module clock parents,
depending on SoC revision.  One option is to use different sets of clock
tables for each SoC revision.  However, if the differences are small, it
is much more space-efficient to have a single set of clock tables, and
fix those up at runtime instead.

Hence provide three helpers:
  - Two helpers to NULLify core and module clocks that do not exist on
    some revisions (NULLified clocks are skipped during the registration
    phase),
  - One helper to reparent module clocks that have different clock
    parents.

Subject: [PATCH 070/151] clk: renesas: r8a7795: Add support for R-Car H3 ES2.0

The Clock Pulse Generator / Module Standby and Software Reset module in
R-Car H3 ES2.0 differs from ES1.x in the following areas:
  - More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12),
  - Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR,
    SYS-DMAC, VIN, VSPB, VSPI,
  - Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2,
    USB3-IF1, VSPD3, VSPI2,
  - Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1.

The goal is twofold:
  1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
     for now,
  2. Make it clear which code supports ES1.x, so it can easily be
     identified and removed later, when production SoCs are deemed
     ubiquitous.

This is achieved by:
  - Updating the clock tables for the latest revision (ES2.0), but not
    removing clocks that only exist on earlier revisions (ES1.x),
  - Detecting the SoC revision at runtime using the new soc_device_match()
    API, and fixing up the clocks tables to match the actual SoC
    revision, by:
      - NULLifying core and module clocks of modules that do not exist,
      - Reparenting module clocks that have a different parent on ES1.x.

Based on R-Car Gen3 Hardware User's Manual rev. 0.53E.

Subject: [PATCH 071/151] clk: renesas: rcar-gen3-cpg: Add support for RCLK on
 R-Car H3 ES2.0

Starting with R-Car H3 ES2.0, the parent of RCLK is selected using MD28.

Add support for that, but retain the old behavior for R-Car H3 ES1.x and
M3-W ES1.0 using a quirk.

Inspired by a patch by Takeshi Kihara in the BSP.

Subject: [PATCH 074/151] clk: tegra: Don't reset PLL-CX if it is already
 enabled

Commit 8dce89a1c2cf ("clk: tegra: Don't warn for PLL defaults
unnecessarily") changed the tegra210_pllcx_set_defaults() function
causing the PLL to always be reset regardless of whether it is in-use.
This function was changed so that resetting of the PLL will only be
skipped if the PLL is enabled AND 'pllcx->params->defaults_set' is not
true. However, the 'pllcx->params->defaults_set' is always true and
hence, the PLL is now always reset. This causes the boot to fail on the
Tegra210 Smaug where the PLL is already enabled and in-use. Fix this by
only resetting the PLL if not in-use and only printing the warning that
the defaults are not set after we have checked the default settings.

Fixes: 8dce89a1c2cf ("clk: tegra: Don't warn for PLL defaults unnecessarily")

Subject: [PATCH 077/151] clk: meson-gxbb: Add MALI clocks

The Mali is clocked by two identical clock paths behind a glitch free mux
to safely change frequency while running.

The two "mali_0" and "mali_1" clocks are composed of a mux, divider and gate.
Expose these two clocks trees using generic clocks.
Finally the glitch free mux is added as "mali" clock.

Subject: [PATCH 078/151] clk: meson: Add support for parameters for specific
 PLLs

In recent Amlogic GXBB, GXL and GXM SoCs, the GP0 PLL needs some specific
parameters in order to initialize and lock correctly.

This patch adds an optional PARAM table used to initialize the PLL to a
default value with it's parameters in order to achieve to desired frequency.

The GP0 PLL in GXBB, GXL/GXM also needs some tweaks in the initialization
steps, and these are exposed along the PARAM table.

Tha Amlogic GXBB SoC GP0 PLL needs some vendor provided parameters to be
initializated in the the GP0 control registers before configuring the rate
with the rate table provided parameters.

GXBB GP0 PLL tweaks are also selected to respect the vendor init procedure.

Subject: [PATCH 080/151] clk: meson-gxbb: Add GXL/GXM GP0 Variant

The clock tree in the Amlogic GXBB and GXL/GXM SoCs is shared, but the GXL/GXM
SoCs embeds a different GP0 PLL, and needs different parameters with a vendor
provided reduced rate table.

This patch adds the GXL GP0 variant, and adds a GXL DT compatible in order
to use the GXL GP0 PLL instead of the GXBB specific one.

Subject: [PATCH 081/151] clk: sunxi-ng: mult: Support PLL lock detection

Some PLL clocks are N (multiplier) type clocks, or can be simplified
as such. An example of the former is the DDR1 PLL clock on the A33.
An example of the latter is the CPU PLL clock on the A80, in which
the P divider is only used for low frequencies that are of little
use. Both clocks support PLL lock detection.

The mult clock macro implies support for this, but that is not true.
The field is simply discarded. This patch adds proper support for it.

Subject: [PATCH 082/151] clk: sunxi-ng: a80: Remodel CPU cluster PLLs as
 N-type multiplier clocks

The CPU cluster PLLs on the A80 are NP clocks that are atypical in two ways:

  - The P factor is 1 bit wide, and translates to a /1 or /4 divider.

  - The P factor should only be used for output frequencies lower than
    288 MHz. The N factor has a lower limit of 12, which likely contributed
    to this extra divider.

According to the user manual, the clocks can only go as low as 200 MHz.
The vendor BSP kernel does not even define operating points below 360
MHz for these clocks. The lower end for cpufreq in the vendor kernel is
even higher. The mainline Linux kernel doesn't support cpufreq for the
A80 at the moment. This means the lower frequencies are untested, and
will likely remain unused.

The new sunxi-ng style clocks don't support the quirks listed above.
Instead of trying to work the quirks in for something of little usage,
we re-model the clocks into N-type multipler clocks, with P fixed at 1.
At probe time we check if P is set to 4, and fix it up if needed. This
is highly unlikely though.

The DDR1 PLL on the A33 is an oddball amongst the A33 CCU clocks.
It is a clock multiplier, with the effective multiplier in the
range of 12 ~ 255 and no offset between the multiplier value and
the value programmed into the register.

Implement the zero offset and minimum value of 12 for this clock.

Subject: [PATCH 087/151] clk: meson: add audio clock divider support

The audio divider needs a specific clock divider driver.
With am mpll parent clock, which is able to provide a fairly precise rate,
the generic divider tends to select low value of the divider. In such case
the quality of the clock is very poor. For the same final rate, maximizing
the audio clock divider value and selecting the corresponding mpll rate
gives better results. This is what this driver aims to acheive. So far, so
good.

Subject: [PATCH 090/151] clk: meson: gxbb: add cts_i958 clock

This adds the cts_i958 clock to control the clock source of the spdif
output block. This mux is not explicitly mentionned in the documentation
but it is critical to the spdif dai. It is used to select whether the clock
source of the spdif output is cts_amclk (when data are taken from i2s
buffer) or the cts_mclk_i958 (when data are taken from the spdif buffer)

Subject: [PATCH 091/151] clk: meson: mpll: fix division by zero in
 rate_from_params

According to the public datasheet all register bits in HHI_MPLL_CNTL7,
HHI_MPLL_CNTL8 and HHI_MPLL_CNTL9 default to zero. On all GX SoCs these
seem to be initialized by the bootloader to some default value.
However, on my Meson8 board they are not initialized, leading to a
division by zero in rate_from_params as the math is:
(parent_rate * SDM_DEN) / ((SDM_DEN * 0) + 0)

According to the datasheet, the minimum n2 value is 4. The rate provided
by the clock when n2 is less than this minimum is unpredictable. In such
case, we report an error.

Although the rate_from_params function was only introduced recently the
original bug has been there for much longer. It was only exposed
recently when the MPLL clocks were added to the Meson8b clock driver.

Subject: [PATCH 092/151] clk: meson: mpll: use 64bit math in rate_from_params

On Meson8b the MPLL parent clock (fixed_pll) has a rate of 2550MHz.
Multiplying this with SDM_DEN results in a value greater than 32bits.
This is not a problem on the 64bit Meson GX SoCs, but it may result in
undefined behavior on the older 32bit Meson8b SoC.

While rate_from_params was only introduced recently to make the math
reusable from _round_rate and _recalc_rate the original bug exists much
longer.

Subject: [PATCH 102/151] clk: zte: set CLK_SET_RATE_PARENT for a few zx296718
 clocks

To support VOU VGA display driver with different modes, we need to set
flag for a few clocks, so that clk_set_rate() call in VOU driver can get
VGA device desired pixel rate.

While at it, the divider between pll_vga and clk_vga gets corrected, as
it's 1:1 instead of 1:2.

Subject: [PATCH 103/151] clk: zte: pd_bit is not 0 on zx296718

The bit 0 of PLL_CFG0 register is not powerdown on zx296718, but part of
of postdiv2 field.  The consequence is that functions like hw_to_idx()
and zx_pll_enable() will end up tampering the postdiv2 of the PLL.

Let's fix it by defining pd_bit 0xff which is obviously invalid for a
bit position and having PLL driver check the validity before operating
on the bit.

In case there are multiple notify chains for the same clocks (because they
were registered by different users), we need to propagate potential failure
of any single one of them to the caller. Otherwise we eg risk violating the

Subject: [PATCH 113/151] clk: vc5: Add structure to describe particular chip
 features

Introduce vc5_chip_info structure to describe features of a particular
VC5 chip (id, number of FODs, number of outputs, flags).
For now flags are only used to indicate if chip has internal XTAL.
vc5_chip_info is set on probe from the matched of_device_id->data.

Also add defines to specify maximum number of FODs and clock outputs
supported by the driver.

With these changes it should be easier to extend driver to support
more VC5 models.

Subject: [PATCH 115/151] clk: vc5: Add support for IDT VersaClock 5P49V5935

Update IDT VersaClock 5 driver to support 5P49V5935. This chip has
two clock inputs (internal XTAL or external CLKIN), four fractional
dividers (FODs) and five clock outputs (four universal clock outputs
and one reference clock output at OUT0_SELB_I2C).

Current driver supports up to 2 FODs and up to 3 clock outputs. This
patch sets max number of supported FODs to 4 and max number of supported
clock outputs to 5.

MX7D ahb clk actually has no LPCG gate, current LPCG offset 0x4200
used actually is for adc, not ahb. After fix, correct ocram_s_clk

There is no SPEAr600 device named "adc". Instead, the description of the
ADC was recently added to the Device Tree, and the device name is
"d820b000.adc", so we should associate the ADC gatable clock to this
device name.

Subject: [PATCH 125/151] clk: x86: add "mclk" alias for Baytrail/Cherrytrail

Due to timing requirements, TI and Conexant manage the audio
reference clock from their ASoC codec drivers using the "mclk"
string. This patch adds another lookup for the "pmc_plt_clk_3"
clock to avoid Intel-specific tests in those codec drivers and
use code as-is.

To avoid a leak, clk_add_alias() is not used in this patch.
Instead the lookup is created manually as part of the .probe()
step and dropped in the .remove() step.

"pmc_plt_clk_3" is used exclusively for audio on all known
Baytrail/CherryTrail designs and is e.g. routed on the MCLK
(pin 26) of the MinnowBoardMAX Turbot LSE connector.

Subject: [PATCH 128/151] clk: cs2000: tidyup DEVICE_CFG2 settings

DEVICE_CFG2 can select ratio from user defined ratio and LOCKCLK is
for it. But current driver sets fixed 0 value. This patch fixes it.
Note is that current cs2000 driver is using/supporting only ratio0
(= ch0) now.

DEVICE_CFG2 can select STATIC/DYNAMIC ratio mode, and current cs2000
driver is selecting STATIC mode, but it was not understandable on
current code. This patch also solve this issue.

cs2000 can select Static/Dynamic ratio based Frequency Synthesizer
Mode, it can select 20.12 High Multiplier interpret for 32-bit
User Defined Ratio if Dynamic ratio mode. Otherwise it should select
12.20 High Accuracy mode.
Current cs2000 is supporting Static ratio mode only, so it should
select 12.20 High Accuracy mode, not 20.12 High Multiplier mode.
This patch fixes it.

Subject: [PATCH 136/151] clk: ti: fix linker error with !SOC_OMAP4

When none of the OMAP4-generation SoCs are enabled, we run into a link
error for am43xx/am43xx:

drivers/clk/ti/dpll.o: In function `of_ti_am3_dpll_x2_setup':
dpll.c:(.init.text+0xd8): undefined reference to `clkhwops_omap4_dpllmx'

This is easily fixed by adding another #ifdef.

While looking at the code, I also spotted another problem with the
assignment of hw_ops variable that is not used again later. I'm
changing this to setting clk_hw->ops instead, which I guess is what
was intended here.

Moving the match table down fixes it.

Subject: [PATCH 138/151] clk: hi6220: Add the hi655x's pmic clock

The hi655x multi function device is a PMIC providing regulators.

The PMIC also provides a clock for the WiFi and the Bluetooth, let's implement
this clock in order to add it in the hi655x MFD and allow proper wireless
initialization.

Subject: [PATCH 147/151] clk: nomadik: Delete error messages for a failed
 memory allocation in two functions

The script "checkpatch.pl" pointed information out like the following.

WARNING: Possible unnecessary 'out of memory' message

Thus remove such statements here.

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "kcalloc".

This issue was detected by using the Coccinelle software.

* Multiplications for the size determination of memory allocations
  indicated that array data structures should be processed.
  Thus use the corresponding function "kcalloc".

  This issue was detected by using the Coccinelle software.

* Replace the specification of data types by pointer dereferences
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

Subject: [PATCH 150/151] clk: ti: divider: try to fix ti_clk_register_divider

Commit 6c0afb503937 ("clk: ti: convert to use proper register
definition for all accesses") converted all register accesses in
the TI clk driver to use a proper struct instead of a void
pointer casted struct that fits into a u32. Unfortunately, it
missed a conversion here in the didivder code, leading to a
compiler warning like so:

drivers/clk/ti/divider.c: In function 'ti_clk_register_divider':
drivers/clk/ti/divider.c:460:8: error: 'reg' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Treating a 'u32' variable as a structure leads to a stack
overflow here, and the register address we pass down is never
initialized. Convert this part of the code as well so things
work properly.
