Heiko Stuebner 29a30c269a clk: rockchip: add a factor clock type
Add a clock type for fixed factor clocks. This allows us to define fixed
factor clocks where they appear in the clock hierarchy instead of in the
init function.

The additional factor_gate type, finally allows us to model some last
parts of the clock tree correctly.

Heiko Stuebner aebe3ad801 clk: rockchip: fix parent of hclk_vcodec on rk3036
hclk_vcodec is a child of aclk_vcodec with the fixed factor clock
hclk_vcodec_pre in between and not a child of hclk_disp_pre.

Allow sclk_i2s0 and i2s0_frac to change their parents rate as
that the upstream dividers are purely there to feed sclk_i2s0

Shawn Lin bb07698fc8 clk: rockchip: fix wrong mmc phase shift for rk3228
mmc sample shift is 0 for rk3228 refer to user manaul.
So it's broken if we enable mmc tuning for rk3228.

Alexander Kochetkov e8b63288b3 clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks
hclk_cpubus needs to keep running because it is needed for devices like
the rom, i2s0 or spdif to be accessible via cpu. Without that all
accesses to devices (readl/writel) return wrong data. So add it
to the list of critical clocks.

Heiko Stuebner 219a5859c8 clk: rockchip: fix usbphy-related clocks
The otgphy clocks really only drive the phy blocks. These in turn
contain plls that then generate the 480m clocks the clock controller
uses to supply some other clocks like uart0, gpu or the video-codec.

So fix this structure to actually respect that hirarchy and removed
that usb480m fixed-rate clock working as a placeholder till now, as
this wouldn't even work if the supplying phy gets turned off while
its pll-output gets used elsewhere.

Similar to commit 9880d4277f ("clk: rockchip: fix rk3288 cpuclk core

contain the values to be written to use the same paradigm for them on all
supported socs.

Linus Torvalds 6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

Linus Torvalds 6b5a12dbca ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
 and ARMv7 platforms together such that they can all be enabled and
 boot the same kernel. It has been a tremendous amount of cleanup and
 refactoring by a huge number of people, and creation of several new
 (and major) subsystems to better abstract out all the platform details
 in an appropriate manner.
 
 The bulk of this branch is a large patchset from Arnd that brings several
 of the more minor and older platforms we have closer to multiplatform
 support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
 Much of this is moving around header files from old mach directories,
 but there are also some cleanup patches of debug_ll (lowlevel debug
 per-platform options) and other parts.
 
 Linus Walleij also has some patchs to clean up the older ARM Realview
 platforms by finally introducing DT support, and Rob Herring has some
 for ARM Versatile which is now DT-only. Both of these platforms are
 now multiplatform.
 
 Finally, a couple of patches from Russell for Dove PMU, and a fix from
 Valentin Rothberg for Exynos ADC, which were rebased on top of the
 series to avoid conflicts.

Russell King 7ed88aa2ef clk: fix clk-gpio.c with optional clock= DT property
When the clock DT property is not given, of_clk_get_parent_count()
returns -ENOENT, which then tries to allocate -2 x 4 bytes of memory,
which of course fails, causing the whole driver to fail to create
the clock.

This causes the SolidRun platforms to fail probing the SDHCI1 interface
which is connected to the WiFi.

Fix this by detecting errno codes, skipping the allocation, and fixing
of_clk_gpio_gate_delayed_register_get() to handle a NULL parent_names
array.

Heiko Stübner 5b73840375 clk: rockchip: fix section mismatches with new child-clocks
To model the muxes downstream of fractional dividers we introduced the
child property, allowing to describe a direct child clock.
The first implementation seems to cause section warnings, as the core
clock-tree is marked as initdata while the data pointed to from the
child element is not.

While there may be some way to also set that missing property in the
inline notation I didn't find it, so to actually fix the issue for now
move the sub-definitions into separate declarations that can have
their own __initdata properties.

Remi Pommarel 6d18b8adbe clk: bcm2835: Support for clock parent selection
Some bcm2835 clocks used by hardware (like "PWM" or "H264") can have multiple
parent clocks. These clocks divide the rate of a parent which can be selected by
setting the proper bits in the clock control register.

Previously all these parents where handled by a mux clock. But a mux clock
cannot be used because updating clock control register to select parent needs a
password to be xor'd with the parent index.

This patch get rid of mux clock and make these clocks handle their own parent,
allowing them to select the one to use.

Heiko Stuebner 8ca1ca8f60 clk: rockchip: handle mux dependency of fractional dividers
The fractional dividers of Rockchip SoCs contain an "auto-gating-feature"
that requires the downstream mux to actually point to the fractional
divider and the fractional divider gate to be enabled, for it to really
accept changes to the divider ratio.

The downstream muxes themselfs are not generic enough to include them
directly into the fractional divider, as they have varying sources of
parent clocks including not only clocks related to the fractional
dividers but other clocks as well.

To solve this, allow our clock branches to specify direct child clock-
branches in the new child property, let the fractional divider register
its downstream mux through this and add a clock notifier that temporarily
switches the mux setting when it notices rate changes to the fractional
divider.

Eric Anholt 5e63dcc74b clk: bcm2835: Add a driver for the auxiliary peripheral clock gates.
There are a pair of SPI masters and a mini UART that were last minute
additions.  As a result, they didn't get integrated in the same way as
the other gates off of the VPU clock in CPRMAN.
