Pull clk updates from Stephen Boyd: "This is all driver updates, the majority of which is a bunch of new Qualcomm clk drivers that dominate the diffstat because we add support for six SoCs from that particular vendor. The other big change is the removal of various clk drivers that are no longer used now that the kernel is dropping support for those SoCs. Beyond that there's the usual non-critical fixes for existing drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1 enabled builds. Removed Drivers: - Remove efm32 clk driver - Remove tango4 clk driver - Remove zte zx clk driver - Remove sirf prima2/atlast clk drivers - Remove u300 clk driver New Drivers: - PLL support on MStar/SigmaStar ARMv7 SoCs - CPU clks for Qualcomm SDX55 - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs - GCC clks for Qualcomm SM8350 - GPU clks for Qualcomm SDM660/SDM630 Updates: - Video clk fixups on Qualcomm SM8250 - Improvements for multimedia clks on Qualcomm MSM8998 - Fix many warnings with W=1 enabled builds under drivers/clk/ - Support crystal load capacitance for Versaclock VC5 - Add a "skip recall" DT binding for Silicon Labs' si570 to avoid glitches at boot - Convert Xilinx VCU clk driver to a proper clk provider driver - Expose Xilinx ZynqMP clk driver to more platforms - Amlogic pll driver fixup - Amlogic meson8b clock controller dt support clean up - Remove mipi clk from the Amlogic axg clock controller - New Rockchip rk3368 clock ids related to camera input - Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk reparenting - A series from Liu Ying that adds some SCU clocks support for i.MX8qxp DC0/MIPI-LVDS subsystems - A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ, and clkout1/2 support for i.MX8MM/MN - Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U - Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs - Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial (HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA (SYS-DMAC) clocks on Renesas R-Car V3U - Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs - Allwinner H616 SoC clk support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (171 commits) clk: mstar: msc313-mpll: Fix format specifier clk: mstar: Allow MStar clk drivers to be compile tested clk: qoriq: use macros to generate pll_mask clk: qcom: Add Global Clock controller (GCC) driver for SC7280 dt-bindings: clock: Add SC7280 GCC clock binding clk: qcom: rpmh: Add support for RPMH clocks on SC7280 dt-bindings: clock: Add RPMHCC bindings for SC7280 clk: qcom: gcc-sm8350: add gdsc dt-bindings: clock: Add QCOM SDM630 and SDM660 graphics clock bindings clk: qcom: Add SDM660 GPU Clock Controller (GPUCC) driver clk: qcom: mmcc-msm8996: Migrate gfx3d clock to clk_rcg2_gfx3d clk: qcom: rcg2: Stop hardcoding gfx3d pingpong parent numbers dt-bindings: clock: Add support for the SDM630 and SDM660 mmcc clk: qcom: Add SDM660 Multimedia Clock Controller (MMCC) driver clk: qcom: gcc-sdm660: Mark GPU CFG AHB clock as critical clk: qcom: gcc-sdm660: Mark MMSS NoC CFG AHB clock as critical clk: qcom: gpucc-msm8998: Allow fabia gpupll0 rate setting clk: qcom: gpucc-msm8998: Add resets, cxc, fix flags on gpu_gx_gdsc clk: qcom: gdsc: Implement NO_RET_PERIPH flag clk: mstar: MStar/SigmaStar MPLL driver ...

2021-02-14clk: qcom: mmcc-msm8996: Migrate gfx3d clock to clk_rcg2_gfx3dAngeloGioacchino Del Regno1-11/+18
In the previous commit ("clk: qcom: rcg2: Stop hardcoding gfx3d pingpong parent numbers") the gfx3d ping-pong ops (clk_gfx3d_ops) were generalized in order to be able to reuse the same ops for more than just one clock for one SoC: follow the change here in the MSM8996 MMCC.

2021-02-14clk: qcom: rcg2: Stop hardcoding gfx3d pingpong parent numbersAngeloGioacchino Del Regno2-20/+46
The function clk_gfx3d_determine_rate is selecting different PLLs to manage the GFX3D clock source in a special way: this one needs to be ping-pong'ed on different PLLs to ensure stability during frequency switching (set a PLL rate, let it stabilize, switch the RCG to the new PLL) and fast frequency transitions. This technique is currently being used in the MSM8996 SoC and the function was assuming that the parents were always at a specific index in the parents list, which is TRUE, if we use this only on the MSM8996 MMCC. Unfortunately, MSM8996 is not the only SoC that needs to ping-pong the graphics RCG, so choices are: 1. Make new special ops just to hardcode *again* other indexes, creating code duplication for (imo) no reason; or 2. Generalize this function, so that it becomes usable for a range of SoCs with slightly different ping-pong configuration. In this commit, the second road was taken: define a new "special" struct clk_rcg2_gfx3d, containing the ordered list of parents to ping-pong the graphics clock on, and the "regular" rcg2 clock structure in order to generalize the clk_gfx3d_determine_rate function and make it working for other SoCs. As for the function itself it is left with the assumption that we need to ping-pong over three parents. The reasons for this are: 1. The initial model was MSM8996, which has 3 parents for the graphics clock pingpong; 2. The other example that was taken into consideration is the SDM630/636/660 SoC gpu clock controller, which is ping-ponging over two dynamic clocked and one fixed clock PLL.

This clock is critical for any access to the GPU: gating it will crash the system when the GPU has been initialized (so, you cannot gate it unless you deinit the Adreno completely). So, to achieve a working state with GPU on, set the CLK_IS_CRITICAL flag to this clock.

2021-02-14clk: qcom: gpucc-msm8998: Allow fabia gpupll0 rate settingAngeloGioacchino Del Regno1-1/+9
The GPU PLL0 is not a fixed PLL and the rate can be set on it: this is necessary especially on boards which bootloader is setting a very low rate on this PLL before booting Linux, which would be unsuitable for postdividing to reach the maximum allowed Adreno GPU frequency of 710MHz (or, actually, even 670MHz..) on this SoC. To allow setting rates on the GPU PLL0, also define VCO boundaries and set the CLK_SET_RATE_PARENT flag to the GPU PLL0 postdivider. With this change, the Adreno GPU is now able to scale through all the available frequencies.

The GPU GX GDSC has GPU_GX_BCR reset and gfx3d_clk CXC, as stated on downstream kernels (and as verified upstream, because otherwise random lockups happen). Also, add PWRSTS_RET and NO_RET_PERIPH: also as found downstream, and also as verified here, to avoid GPU related lockups it is necessary to force retain mem, but *not* peripheral when enabling this GDSC (and, of course, the inverse on disablement). With this change, the GPU finally works flawlessly on my four different MSM8998 devices from two different manufacturers.

2021-02-14clk: qcom: gdsc: Implement NO_RET_PERIPH flagAngeloGioacchino Del Regno2-3/+10
In some rare occasions, we want to only set the RETAIN_MEM bit, but not the RETAIN_PERIPH one: this is seen on at least SDM630/636/660's GPU-GX GDSC, where unsetting and setting back the RETAIN_PERIPH bit will generate chaos and panics during GPU suspend time (mainly, the chaos is unaligned access). For this reason, introduce a new NO_RET_PERIPH flag to the GDSC driver to address this corner case.

2021-02-08clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLsAngeloGioacchino Del Regno1-50/+50
All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs and not generic alphas: this was producing bad effects over the entire clock tree of MSM8998, where any GPLL child clock was declaring a false clock rate, due to their parent also showing the same. The issue resides in the calculation of the clock rate for the specific Alpha PLL type, where Fabia has a different register layout; switching the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate (calculation) reading. While at it, also make these PLLs fixed since their rate is supposed to *never* be changed while the system runs, as this would surely crash the entire SoC. Now all the children of all the PLLs are also complying with their specified clock table and system stability is improved.

Pull clk updates from Stephen Boyd: "The core framework got some nice improvements this time around. We gained the ability to get struct clk pointers from a struct clk_hw so that clk providers can consume the clks they provide, if they need to do something like that. This has been a long missing part of the clk provider API that will help us move away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are added for the clk_set_rate() "range" functions, similar to the tracepoints we already have for clk_set_rate() and we added a column to debugfs to help developers understand the hardware enable state of clks in case firmware or bootloader state is different than what is expected. Overall the core changes are mostly improving the clk driver writing experience. At the driver level, we have the usual collection of driver updates and new drivers for new SoCs. This time around the Qualcomm folks introduced a good handful of clk drivers for various parts of three or four SoCs. The SiFive folks added a new clk driver for their FU740 SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that for various new features. One last thing to note in the driver area is that the i.MX driver has gained a new binding to support SCU clks after being on the list for many months. It uses a two cell binding which is sort of rare in clk DT bindings. Beyond that we have the usual set of driver fixes and tweaks that come from more testing and finding out that some configuration was wrong or that a driver could support being built as a module. Summary: Core: - Add some trace points for clk_set_rate() "range" functions - Add hardware enable information to clk_summary debugfs - Replace clk-provider.h with of_clk.h when possible - Add devm variant of clk_notifier_register() - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw New Drivers: - Bindings for Canaan K210 SoC clks - Support for SiFive FU740 PRCI - Camera clks on Qualcomm SC7180 SoCs - GCC and RPMh clks on Qualcomm SDX55 SoCs - RPMh clks on Qualcomm SM8350 SoCs - LPASS clks on Qualcomm SM8250 SoCs Updates: - DVFS support for AT91 clk driver - Update git repo branch for Renesas clock drivers - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E - Stop using __raw_*() I/O accessors in Renesas clk drivers - One more conversion of DT bindings to json-schema - Make i.MX clk-gate2 driver more flexible - New two cell binding for i.MX SCU clks - Drop of_match_ptr() in i.MX8 clk drivers - Add arch dependencies for Rockchip clk drivers - Fix i2s on Rockchip rk3066 - Add MIPI DSI clks on Amlogic axg and g12 SoCs - Support modular builds of Amlogic clk drivers - Fix an Amlogic Video PLL clock dependency - Samsung Kconfig dependencies updates for better compile test coverage - Refactoring of the Samsung PLL clocks driver - Small Tegra driver cleanups - Minor fixes to Ingenic and VC5 clk drivers - Cleanup patches to remove unused variables and plug memory leaks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) dt-binding: clock: Document canaan,k210-clk bindings dt-bindings: Add Canaan vendor prefix clk: vc5: Use "idt,voltage-microvolt" instead of "idt,voltage-microvolts" clk: ingenic: Fix divider calculation with div tables clk: sunxi-ng: Make sure divider tables have sentinel clk: s2mps11: Fix a resource leak in error handling paths in the probe function clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9 clk: si5351: Wait for bit clear after PLL reset clk: at91: sam9x60: remove atmel,osc-bypass support clk: at91: sama7g5: register cpu clock clk: at91: clk-master: re-factor master clock clk: at91: sama7g5: do not allow cpu pll to go higher than 1GHz clk: at91: sama7g5: decrease lower limit for MCK0 rate clk: at91: sama7g5: remove mck0 from parent list of other clocks clk: at91: clk-sam9x60-pll: allow runtime changes for pll clk: at91: sama7g5: add 5th divisor for mck0 layout and characteristics clk: at91: clk-master: add 5th divisor for mck master clk: at91: sama7g5: allow SYS and CPU PLLs to be exported and referenced in DT dt-bindings: clock: at91: add sama7g5 pll defines clk: at91: sama7g5: fix compilation error ...

50 MHz is an incredibly common clock rate for SD cards to run at. It's "high speed" mode in SD (not very fast these days, but it used to be) or: #define HIGH_SPEED_MAX_DTR 50000000 If we don't support this then older "high speed" cards can only run at 25 MHz or at half their normal speed. There doesn't seem to be any reason to skip this clock rate, so add it.

I would repeat the same commit message that was in commit 5e4b7e82d497 ("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks") but it seems silly to do so when you could just go read that commit. NOTE: this is actually extra terrible because we're missing the 50 MHz rate in the table (see the next patch AKA ("clk: qcom: gcc-sc7180: Add 50 MHz clock rate for SDC2")). That means then when you run an older SD card it'll try to clock it at 100 MHz when it's only specced to run at 50 MHz max. As you can probably guess that doesn't work super well.
