Linus Torvalds 3476195651 There's not much to see in the core framework this time around. Instead the
majority of the diff is the normal collection of driver additions for new SoCs
 and non-critical clk data fixes and updates. The framework must be middle aged.
 
 The two biggest directories in the diffstat show that the Qualcomm and Unisoc
 support added a handful of big drivers for new SoCs but that's not really the
 whole story because those new drivers tend to add large numbers of lines of clk
 data. There's a handful of AT91 clk drivers added this time around too and a
 bunch of improvements to drivers like the i.MX driver. All around lots of
 updates and fixes in various clk drivers which is good to see.
 
 The core framework has only one real major change which has been baking in next
 for the past couple months. It fixes the framework so that it stops caching a
 clk's phase when the phase clk_op returns an error. Before this change we would
 consider some negative errno as a phase and that just doesn't make sense.
 
 Core:
  - Don't show clk phase when it is invalid
 
 New Drivers:
  - Add support for Unisoc SC9863A clks
  - Qualcomm SM8250 RPMh and MSM8976 RPM clks
  - Qualcomm SM8250 Global Clock Controller (GCC) support
  - Qualcomm SC7180 Modem Clock Controller (MSS CC) support
  - EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
  - Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs
 
 Updates:
  - GPU GX GDSC support on Qualcomm sc7180
  - Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
  - A series from Anson to convert i.MX8 clock bindings to json-schema
  - Update i.MX pll14xx driver to include new frequency entries for pll1443x table,
    and return error for invalid PLL type
  - Add missing of_node_put() call for a number of i.MX clock drivers
  - Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
    have the flag on its child cpu clock
  - Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
    via CORE_SEL slice, and source from A53 CCM clk root when we need to
    change ARM PLL frequency. Thus, we can support core running above
    1GHz safely
  - Update i.MX pfdv2 driver to check zero rate and use determine_rate for
    getting the best rate
  - Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d
  - Remove PMC clks from Tegra clk driver
  - Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector
  - Conversion to json-schema of the Renesas CPG/MSSR DT bindings
  - Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N
  - Update Amlogic audio clock gate hierarchy for meson8 and gxbb
  - Update Amlogic g12a spicc clock sources
  - Support for Ingenic X1000 TCU clks

 The conversion of binding files to machine-readable yaml format
 continues, along with fixes found during the validation.
 Andre Przywara takes over maintainership for the old Calxeda Highbank
 platform and provides a number of updates.
 
 The OMAP2+ platforms see a continued move from platform data into
 dts files, for many devices that relied on a mix of auxiliary data
 in addition to the DT description

Peng Fan c88a4c797a clk: imx: pfdv2: determine best parent rate
pfdv2 is only used in i.MX7ULP. To get best pfd output, the i.MX7ULP
Datasheet defines two best PLL rate and pfd frac.

Per Datasheel
All PLLs on i.MX 7ULP either have VCO base frequency of
480 MHz or 528 MHz. So when determine best rate, we also
determine best parent rate which could match the requirement.

For some reason the current parent might not be 480MHz or 528MHz,
so we still take current parent rate as a choice.

And we also enable flag CLK_SET_RATE_PARENT to let parent rate
to be configured.

Anson Huang 83dea32c5c clk: imx: gate4: Switch imx_clk_gate4_flags() to clk_hw based API
Switch the imx_clk_gate4_flags() function to clk_hw based API, rename
accordingly and add a macro for clk based legacy. This allows us to
move closer to a clear split between consumer and provider clk APIs.

Peng Fan 44fa471087 clk: imx: Remove __init for imx_obtain_fixed_clk_hw() API
Some of i.MX SoCs' clock driver will use platform driver model,
and they need to call imx_obtain_fixed_clk_hw() API, so
imx_obtain_fixed_clk_hw() API should NOT be in .init section.
