Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs
- i.MX6SLL SoCs
Removed Drivers:
- ST-Ericsson AB8540/9540
Updates:
- Mediatek MT2701 and MT7622 audsys support and MT2712 updates
- STM32F469 DSI and STM32F769 sdmmc2 support
- GPIO clks can sleep now
- Spreadtrum SC9860 RTC clks
- Nvidia Tegra MBIST workarounds and various minor fixes
- Rockchip phase handling fixes and a memory leak plugged
- Renesas drivers switch to readl/writel from clk_readl/clk_writel
- Renesas gained CPU (Z/Z2) and watchdog support
- Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
- Qualcomm PM8921 PMIC XO buffers
- Amlogic migrates to regmap APIs
- TI Keystone clk latching support
- Allwinner H3 and H5 video clk fixes
- Broadcom BCM2835 PLLs needed another bit to enable
- i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix
- i.MX6UL/ULL epdc_podf support
- Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC"

In order to enable a PLL, not only the PLL has to be powered up and
locked, but you also have to de-assert the reset signal. The last part
was missing. Add it so PLLs that were not enabled by the FW/bootloader
can be enabled from Linux.

For init on clocks we should move it at the first place in imx7d_clocks_init()
before any clock operations, else the clock operation may fail in case the clock
is still not on.

Design team change the ahb's clk parent options but
did NOT update the DOC accordingly in time, so the
AHB/IPG's clk rate in clk tree is incorrect, AHB is
67.5MHz and IPG is 33.75MHz, but using scope to
monitor them, they are actually 135MHz and 67.5MHz,
update the clk parent option to make clk tree info
correct.

The introduction of support for CLK_SET_RATE_PARENT flag for clkctrl
clocks used a generic clock flag, which causes a conflict with the
rest of the clkctrl flags, namely the NO_IDLEST flag. This can cause
boot failures on certain platforms where this flag is introduced, by
omitting the wait for the clockctrl module to be fully enabled before
proceeding with rest of the code.
Fix this by moving all the clkctrl specific flags to their own bit-range.

Since hclk_sd and pclk_ddr source clock from CPLL or GPLL,
and these two PLL may change their frequency. If we do not
assign right id to pclk_ddr and hclk_sd, they will alway use
default cur register value, and may get the frequency
exceed their signed off frequency. So assign correct Id
for them, then we can assign frequency for them in dts.

The newly added clock notifier may return an error code but so far the
error output in the function would only return an error pointer from
registering the clock.
So when the clock notifier fails the clock would be unregistered but the
return would still be the clock pointer which could then not be
dereferenced correctly. So fix the error handling to prevent that.

the phase for coming rate which is out of the scope of boards'

commit c420c1e4db22 ("clk: rockchip: Prevent calculating mmc phase

that the parent of SDMMC phase clock should be sclk_sdmmc0, but not
sclk_sdmmc. However, the naming of the sdmmc clocks varies in the
manual with the card clock having the 0 while the hclk is named
without appended 0. So standardize one one format to prevent
confusion, as there also is only one (non-sdio) mmc controller on
the soc.

There are many factors affecting the clock phase, including clock
rate, temperature, logic voltage and silicon process, etc. But clock
rate is the most significant one here, and the driver should be aware
of the change of the clock rate. As mmc controller need a fixed phase
after tuning was completed, at least before explicitly doing re-tune,
so this patch try to restore the clock phase by monitoring the event
of rate change.

The MMC sample and drv clock for rockchip platforms are derived from
the bus clock output to the MMC/SDIO card. So it should never happens
that the clk rate is zero given it should inherits the clock rate from
its parent. If something goes wrong and makes the clock rate to be zero,
the calculation would be wrong but may still make the mmc tuning process
work luckily. However it makes people harder to debug when the following
data transfer is unstable.

dclk_lcdc can be sourced from a general pll source as well
as the hdmiphy's pll output. We will want to set this source
by hand (to the system-pll-source in most cases) and also
want rate changes to this clock to be able to also touch
the pll source clock if needed, so add CLK_SET_RATE_PARENT
and CLK_SET_RATE_NO_REPARENT for dclk_lcdc.

NIU clocks are supplying the interconnect connections to specific
peripherals and are currently not controlled in any way.
So to prevent things falling apart at strange moments, mark all
niu clocks as critical.
Most of them where marked as CLK_IGNORE_UNUSED, but that doesn't
help if a parent clock then gets disabled.

The clock wrongly was called hclk_vio and exported, while it actually is
a clock of the interconnect-vio connection and should therefore be always
on till we actually model the interconnect.
So fix that and don't export it as HCLK_VIO.

This adds a new driver for the USB PHY clocks in the CFGCHIP2 syscon
register on TI DA8XX-type SoCs.
The USB0 (USB 2.0) PHY clock is an interesting case because it calls
clk_enable() in a reentrant way. The USB 2.0 PSC only has to be enabled
temporarily while we are locking the PLL, which takes place during the
clk_enable() callback.
