During review it came to light that exposing the pll clock outside is
not the right approach and struct phy_configure_opts_mipi_dphy exists
just for that reason to transfer parameters to the phy.
So drop the exposed clock and rely on the phy configure options
to bring in the correct rate. That way we can also just drop the
open coded timing struct and default values function.

Switch network drivers, phy drivers, and SFP/phylink over to use the
more correct 10GBASE-R, rather than 10GBASE-KR. 10GBASE-KR is backplane
ethernet, which is 10GBASE-R with autonegotiation on top, which our
current usage on the affected platforms does not have.
The only remaining user of PHY_INTERFACE_MODE_10GKR is the Aquantia
PHY, which has a separate mode for 10GBASE-KR.
For Marvell mvpp2, we detect 10GBASE-KR, and rewrite it to 10GBASE-R
for compatibility with existing DT - this is the only network driver
at present that makes use of PHY_INTERFACE_MODE_10GKR.

Commit 287422a95f ("drm/rockchip: Round up _before_ giving to the clock framework")
changed what rate clk_round_rate() is called with, an additional 999 Hz
added to the requsted mode clock. This has caused a regression on RK3328
and presumably also on RK3228 because the inno-hdmi-phy clock requires an
exact match of the requested rate in the pre pll config table.
When an exact match is not found the parent clock rate (24MHz) is returned
to the clk_round_rate() caller. This cause wrong pixel clock to be used and
result in no-signal when configuring a mode on RK3328.
Fix this by rounding the rate down to closest 1000 Hz in round_rate func,
this allows an exact match to be found in pre pll config table.

When docked to a Motorola lapdock or media dock, we're in USB A-host mode
with VBUS provided by the dock. When in regular USB A-host mode, we're
providing the VBUS. And in regular USB A-host mode we must also keep
kicking the VBUS to keep it active.
Let's wait a bit before configuring the USB PHY to allow some time between
the ID and VBUS changes. And let's add vbus_provider flag so we can detect
docked mode and regularo USB A-host mode better.
With better USB A-host mode detection, we can now also just kick the
VBUS to keep it enabled and leave out the unnecessary line muxing.
We only need to set and clear vbus_provider in the delayed work so no
locking is needed for it currently.

The micro-USB connector on Motorola Mapphone devices can be muxed between
the SoC and the mdm6600 modem. But even when used for the SoC, configuring
the PHY with ID pin grounded will wake up the modem from idle state. Looks
like the issue is probably caused by line glitches.
We can prevent the glitches by using a previously unknown mode of the
GPIO mux to prevent the USB lines from being connected to the moden while
configuring the USB PHY, and enable the USB lines after configuring the
PHY.
Note that this only prevents waking up mdm6600 as regular USB A-host mode,
and does not help when connected to a lapdock. The lapdock specific issue
still needs to be debugged separately.

Commit f0b5c2c963 ("phy: qcom-usb-hs: Replace the extcon API")
switched from extcon_register_notifier() to the resource-managed
API, i.e. devm_extcon_register_notifier().
This is problematic in this case, because the extcon notifier
is dynamically registered/unregistered whenever the PHY is powered
on/off. The resource-managed API does not unregister the notifier
until the driver is removed, so as soon as the PHY is power cycled,
attempting to register the notifier again results in:
double register detected
WARNING: CPU: 1 PID: 182 at kernel/notifier.c:26 notifier_chain_register+0x74/0xa0

extcon_register_notifier+0x74/0xb8
devm_extcon_register_notifier+0x54/0xb8
qcom_usb_hs_phy_power_on+0x1fc/0x208
...
... and USB stops working after plugging the cable out and in
another time.
The easiest way to fix this is to make a partial revert of
commit f0b5c2c963 ("phy: qcom-usb-hs: Replace the extcon API")
and avoid using the resource-managed API in this case.

clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:
- Add regulator support to the cdce925 clk driver
- Add support for Raspberry Pi 4 bcm2711 SoCs
- Add SDIO gate support to aspeed driver
- Add missing of_node_put() calls in various clk drivers
- Migrate Amlogic driver to new clock parent description method
- Add DVFS support to Amlogic Meson g12
- Add Amlogic Meson g12a reset support to the axg audio clock controller
- Add sm1 support to the Amlogic Meson g12a clock controller
- Switch i.MX8MM clock driver to platform driver
- Add Hifi4 DSP related clocks for i.MX8QXP SoC
- Fix Audio PLL setting and parent clock for USB
- Misc i.MX8 clock driver improvements and corrections
- Set floor ops for Qualcomm SD clks so that rounding works
- Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1

new features for existing drivers, and bug fixes scattered throughout.
The biggest diffstat is the Amlogic driver that gained CPU clk support
in addition to migrating to the new way of specifying clk parents.
After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got
support for various new SoCs and clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:
- Add regulator support to the cdce925 clk driver
- Add support for Raspberry Pi 4 bcm2711 SoCs
- Add SDIO gate support to aspeed driver
- Add missing of_node_put() calls in various clk drivers
- Migrate Amlogic driver to new clock parent description method
- Add DVFS support to Amlogic Meson g12
- Add Amlogic Meson g12a reset support to the axg audio clock controller
- Add sm1 support to the Amlogic Meson g12a clock controller
- Switch i.MX8MM clock driver to platform driver
- Add Hifi4 DSP related clocks for i.MX8QXP SoC
- Fix Audio PLL setting and parent clock for USB
- Misc i.MX8 clock driver improvements and corrections
- Set floor ops for Qualcomm SD clks so that rounding works
- Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1
- Enable the Allwinner V3 SoC and fix the i2s clock for H6"

We are currently not enabling VBUS boost for cpcap when in host mode.
This means the VBUS is fed at the battery voltage level, which can cause
flakeyness enumerating devices.
Looks like the boost control for VBUS is CPCAP_BIT_VBUS_SWITCH that we
must enable in the charger for nice 4.92 V VBUS output. And looks like
we must not use the STBY pin enabling but must instead use manual VBUS
control in phy-cpcap-usb.
We want to do this in cpcap_charger_vbus_work() and also set a flag for
feeding_vbus to avoid races between USB detection and charger detection,
and disable charging if feeding_vbus is set.

There is no public clock tree that implies such dependencies between
the MG/MG-core/AXI clocks and the COMPHY IP but accessing the COMPHY
registers while one of the three clocks are disabled stalls the CPU.
This happens if, for instance, the COMPHY driver probe is deferred
(eg. the USB Vbus regulator driver is not yet visible). The MVPP2
driver which also needs these clocks (among others) will
prepare/enable the clocks, then be deferred, and disable/unprepare
them. Next COMPHY lane to be configured would produce an infinite

Despite extensive testing of commit 885bd76596 ("phy: qcom-qmp: Correct
READY_STATUS poll break condition") I failed to conclude that the
PHYSTATUS bit of the PCS_STATUS register used in PCIe and USB3 falls as
the PHY gets ready. Similar to the prior bug with UFS the code will
generally get past the check before the transition and thereby
"succeed".
Correct the name of the register used PCIe and USB3 PHYs, replace
mask_pcs_ready with a constant expression depending on the type of the
PHY and check for the appropriate ready state.

The hardware manual should be revised, but the initial value of
VBCTRL.OCCLREN is set to 1 actually. If the bit is set, the hardware
clears VBCTRL.VBOUT and ADPCTRL.DRVVBUS registers automatically
when the hardware detects over-current signal from a USB power switch.
However, since the hardware doesn't have any registers which
indicates over-current, the driver cannot handle it at all. So, if
"is_otg_channel" hardware detects over-current, since ADPCTRL.DRVVBUS
register is cleared automatically, the channel cannot be used after
that.
To resolve this behavior, this patch sets the VBCTRL.OCCLREN to 0
to keep ADPCTRL.DRVVBUS even if the "is_otg_channel" hardware
detects over-current. (We assume a USB power switch itself protects
over-current and turns the VBUS off.)
This patch is inspired by a BSP patch from Kazuya Mizuguchi.

PHY configuration has been implemented in the firmware and accessed
through SMC calls. In the past, it worked magically if the bootloader
was correctly doing the initializations.
With up-to-date bindings, the kernel will need a recent firmware in
order to do the initializations himself (we assume people must update
their firmware along with their kernel).
People might not understand why IPs that were working correctly before
stopped to be probed suddendly. In this case, let's advise the users
to update their firmware with a visual warning.

The Lantiq VRX200 SoCs embed a PCIe PHY in the "sram" bus. Unlike most
other IP blocks on this SoC the register values are only 16-bit wide.
Like other IP blocks on this SoC the register values are in big endian.
The PHY embeds a PLL which can be configured in various modes. Only the
36MHz mode is supported for now, the other modes can be implemented when
there's a board which actually needs them. OpenWrt uses the out-of-tree
vendor driver and all supported boards there only need the 36MHz mode.
There are two input clocks:
- the "pdi" clock enables the register access
- the "phy" clock is the clock input and enables the internal PLL
There are two reset lines:
- "phy" resets the PHY itself
- the "pcie" reset line is shared between the PHY and the PCIe
controller
While the VRX200 SoC has only one PCIe controller and PHY the ARX300
uses two identical PCIe controllers and PHYs which are compatible with
the PCIe controller and PHY on VRX200.
Add a driver for this PHY so PCIe support can be enabled on these SoCs.

Locking is not needed for the phy_g12a_usb3_pcie_cr_bus_read/write() and
currently it causes the following BUG because of the usage of the
regmap_read_poll_timeout() running in spinlock_irq, configured by regmap fast_io.
Simply disable locking in the cr_regmap config since it's only used from the
PHY init callback function.
BUG: sleeping function called from invalid context at drivers/phy/amlogic/phy-meson-g12a-usb3-pcie.c:85

This adds support for the Mixel DPHY as found on i.MX8 CPUs but since
this is an IP core it will likely be found on others in the future. So
instead of adding this to the nwl host driver make it a generic PHY
driver.
The driver supports the i.MX8MQ. Support for i.MX8QM and i.MX8QXP can be
added once the necessary system controller bits are in via
mixel_dphy_devdata.

After issuing a PHY_START request to the QMP, the hardware documentation
states that the software should wait for the PCS_READY_STATUS to become
1.
With the introduction of commit c9b589791f ("phy: qcom: Utilize UFS
reset controller") an additional 1ms delay was introduced between the
start request and the check of the status bit. This greatly increases
the chances for the hardware to actually becoming ready before the
status bit is read.
The result can be seen in that UFS PHY enabling is now reported as a
failure in 10% of the boots on SDM845, which is a clear regression from
the previous rare/occasional failure.
This patch fixes the "break condition" of the poll to check for the
correct state of the status bit.
Unfortunately PCIe on 8996 and 8998 does not specify the mask_pcs_ready
register, which means that the code checks a bit that's always 0. So the
patch also fixes these, in order to not regress these targets.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct samsung_usb2_phy_driver {
...
struct samsung_usb2_phy_instance instances[0];
};
instance = devm_kzalloc(dev, sizeof(struct samsung_usb2_phy_driver) +
count * sizeof(struct samsung_usb2_phy_instance),
GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = devm_kzalloc(dev, struct_size(instance, instances, count),
GFP_KERNEL);
This code was detected with the help of Coccinelle.

Prior to the adoption of SPDX, it was difficult for tools to determine
the correct license due to incomplete or badly formatted license text.
The SPDX solves this issue, assuming people can correctly spell
"SPDX-License-Identifier" although this assumption is broken in some
places.
Since scripts/spdxcheck.py parses only lines that exactly matches to
the correct tag, it cannot (should not) detect this kind of error.
If the correct tag is missing, scripts/checkpatch.pl warns like this:
WARNING: Missing or malformed SPDX-License-Identifier tag in line *
So, people should notice it before the patch submission, but in reality
broken tags sometimes slip in. The checkpatch warning is not useful for
checking the committed files globally since large number of files still
have no SPDX tag.
Also, I am not sure about the legal effect when the SPDX tag is broken.
Anyway, these typos are absolutely worth fixing. It is pretty easy to
find suspicious lines by grep.

Here is the big set of USB and PHY driver patches for 5.2-rc1
There is the usual set of:
- USB gadget updates
- PHY driver updates and additions
- USB serial driver updates and fixes
- typec updates and new chips supported
- mtu3 driver updates
- xhci driver updates
- other tiny driver updates
Nothing really interesting, just constant forward progress.
All of these have been in linux-next for a while with no reported

but both of them had been in linux-next before they got merged here last

The phy code was using implicit sequencing between the PHY driver
and the UFS driver to implement certain hardware requirements.
Specifically, the PHY reset register in the UFS controller needs
to be deasserted before serdes start occurs in the PHY.
Before this change, the code was doing this by utilizing the two
phy callbacks, phy_init() and phy_poweron(), as "init step 1" and
"init step 2", where the UFS driver would deassert reset between
these two steps.
This makes it challenging to power off the regulators in suspend,
as regulators are initialized in init, not in poweron(), but only
poweroff() is called during suspend, not exit().
For UFS, move the actual firing up of the PHY to phy_poweron() and
phy_poweroff() callbacks, rather than init()/exit(). UFS calls
phy_poweroff() during suspend, so now all clocks and regulators for
the phy can be powered down during suspend.
QMP is a little tricky because the PHY is also shared with PCIe and
USB3, which have their own definitions for init() and poweron(). Rename
the meaty functions to _enable() and _disable() to disentangle from the
PHY core names, and then create two different ops structures: one for
UFS and one for the other PHY types.
In phy-qcom-ufs, remove the 'is_powered_on' and 'is_started' guards,
as the generic PHY code does the reference counting. The
14/20nm-specific init functions get collapsed into the generic power_on()
function, with the addition of a calibrate() callback specific to 14/20nm.

Add support for the XUSB pad controller found on Tegra186 SoCs. It is
mostly similar to the same IP found on earlier chips, but the number of
pads exposed differs, as do the programming sequences.
Note that the DVDD_PEX, DVDD_PEX_PLL, HVDD_PEX and HVDD_PEX_PLL power
supplies of the XUSB pad controller require strict power sequencing and
are therefore controlled by the PMIC on Tegra186.
