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"

.disable operations. Those operations are thus not allowed to sleep,
and calls to the clk_enable(), clk_disable() API functions are allowed in
atomic context.
For clk_is_enabled() API, it is also designed to be allowed to be used in
atomic context. However, it doesn't really make any sense to hold the enable
lock in core, unless you want to do something else with the information of
the enable state with that lock held. Otherwise, seeing if a clk is enabled is
a one-shot read of the enabled state, which could just as easily change after
the function returns because the lock is released. Thus the user of this API
needs to handle synchronizing the read of the state with whatever they're
using it for to make sure that the enable state doesn't change during that
time.
The prepare lock is a mutex and is held across calls to all other operations.
All those operations are allowed to sleep, and calls to the corresponding API

Reference
This binding uses the common clock binding[1]. Details about the device can be
found in the datasheet[2].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
[2] Si544 datasheet
https://www.silabs.com/documents/public/data-sheets/si544-datasheet.pdf
Required properties:
- compatible: One of "silabs,si514a", "silabs,si514b" "silabs,si514c" according
to the speed grade of the chip.
- reg: I2C device address.
- #clock-cells: From common clock bindings: Shall be 0.
Optional properties:
- clock-output-names: From common clock bindings. Recommended to be "si544".

STMicroelectronics STM32 Peripheral Reset Clock Controller
==========================================================
The RCC IP is both a reset and a clock controller.
RCC makes also power management (resume/supend and wakeup interrupt).
Please also refer to reset.txt for common reset controller binding usage.
Please also refer to clock-bindings.txt for common clock controller
binding usage.
Required properties:
- compatible: "st,stm32mp1-rcc", "syscon"
- reg: should be register base and length as documented in the datasheet
- #clock-cells: 1, device nodes should specify the clock in their
"clocks" property, containing a phandle to the clock device node,
an index specifying the clock to use.
- #reset-cells: Shall be 1
- interrupts: Should contain a general interrupt line and a interrupt line
to the wake-up of processor (CSTOP).
Example:
rcc: rcc@50000000 {
compatible = "st,stm32mp1-rcc", "syscon";
reg = <0x50000000 0x1000>;
#clock-cells = <1>;
#reset-cells = <1>;
interrupts = <GIC_SPI 5 IRQ_TYPE_NONE>,
<GIC_SPI 145 IRQ_TYPE_NONE>;
};
Specifying clocks
=================
All available clocks are defined as preprocessor macros in
dt-bindings/clock/stm32mp1-clks.h header and can be used in device
tree sources.
Specifying softreset control of devices
=======================================
Device nodes should specify the reset channel required in their "resets"
property, containing a phandle to the reset device node and an index specifying
which channel to use.
The index is the bit number within the RCC registers bank, starting from RCC
base address.
It is calculated as: index = register_offset / 4 * 32 + bit_offset.
Where bit_offset is the bit offset within the register.
For example on STM32MP1, for LTDC reset:
ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset
= 0x180 / 4 * 32 + 0 = 3072
The list of valid indices for STM32MP1 is available in:
include/dt-bindings/reset-controller/stm32mp1-resets.h
