2022-02-24clk: qcom: dispcc: Update the transition delay for MDSS GDSCTaniya Das
On SC7180 we observe black screens because the gdsc is being enabled/disabled very rapidly and the GDSC FSM state does not work as expected. This is due to the fact that the GDSC reset value is being updated from SW. The recommended transition delay for mdss core gdsc updated for SC7180/SC7280/SM8250.

2022-02-24clk: qcom: gdsc: Add support to update GDSC transition delayTaniya Das
GDSCs have multiple transition delays which are used for the GDSC FSM states. Older targets/designs required these values to be updated from gdsc code to certain default values for the FSM state to work as expected. But on the newer targets/designs the values updated from the GDSC driver can hamper the FSM state to not work as expected. On SC7180 we observe black screens because the gdsc is being enabled/disabled very rapidly and the GDSC FSM state does not work as expected. This is due to the fact that the GDSC reset value is being updated from SW. Thus add support to update the transition delay from the clock controller gdscs as required.

2022-02-17clk: qcom: gcc-msm8994: Remove NoC clocksKonrad Dybcio
Just like in commit 05cf3ec00d46 ("clk: qcom: gcc-msm8996: Drop (again) gcc_aggre1_pnoc_ahb_clk") adding NoC clocks turned out to be a huge mistake, as they cause a lot of issues at little benefit (basically letting Linux know about their children's frequencies), especially when mishandled or misconfigured. Adding these ones broke SDCC approx 99 out of 100 times, but that somehow went unnoticed. To prevent further issues like this one, remove them. This commit is effectively a revert of 74a33fac3aab ("clk: qcom: gcc-msm8994: Add missing NoC clocks") with ABI preservation.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have a couple patches in the framework core this time around but they're mostly minor cleanups and some debugfs stuff. The real work that's in here is the typical pile of clk driver updates and new SoC support. Per usual (or maybe just recent trends), Qualcomm gains a handful of SoC drivers additions and has the largest diffstat. After that there are quite a few updates to the Allwinner (sunxi) drivers to support modular drivers and Renesas is heavily updated to add more support for various clks. Overall it looks pretty normal. New Drivers: - Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770 - MediaTek mt7986 SoC basic support - Clock and reset driver for Toshiba Visconti SoCs - Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8) - Allwinner D1 clks - Lan966x Generic Clock Controller driver and associated DT bindings - Qualcomm SDX65, SM8450, and MSM8976 GCC clks - Qualcomm SDX65 and SM8450 RPMh clks Updates: - Set suppress_bind_attrs to true for i.MX8ULP driver - Switch from do_div to div64_ul for throughout all i.MX drivers - Fix imx8mn_clko1_sels for i.MX8MN - Remove unused IPG_AUDIO_ROOT from i.MX8MP - Switch parent for audio_root_clk to audio ahb in i.MX8MP driver - Removal of all remaining uses of __clk_lookup() in drivers/clk/samsung - Refactoring of the CPU clocks registration to use common interface - An update of the Exynos850 driver (support for more clock domains) required by the E850-96 development board - Prep for runtime PM and generic power domains on Tegra - Support modular Allwinner clk drivers via platform bus - Lan966x clock driver extended to support clock gating - Add serial (SCI1), watchdog (WDT), timer (OSTM), SPI (RSPI), and thermal (TSU) clocks and resets on Renesas RZ/G2L - Rework SDHI clock handling in the Renesas R-Car Gen3 and RZ/G2 clock drivers, and in the Renesas SDHI driver - Make the Cortex-A55 (I) clock on Renesas RZ/G2L programmable - Document support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add support for the new Renesas R-Car S4-8 (R8A779F0) SoC - Add GPU clock and resets on Renesas RZ/G2L - Add clk-provider.h to various Qualcomm clk drivers - devm version of clk_hw_register_gate() - kerneldoc fixes in a couple drivers" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (131 commits) clk: visconti: Remove pointless NULL check in visconti_pll_add_lookup() clk: mediatek: add mt7986 clock support clk: mediatek: add mt7986 clock IDs dt-bindings: clock: mediatek: document clk bindings for mediatek mt7986 SoC clk: mediatek: clk-gate: Use regmap_{set/clear}_bits helpers clk: mediatek: clk-gate: Shrink by adding clockgating bit check helper clk: x86: Fix clk_gate_flags for RV_CLK_GATE clk: x86: Use dynamic con_id string during clk registration ACPI: APD: Add a fmw property clk-name drivers: acpi: acpi_apd: Remove unused device property "is-rv" x86: clk: clk-fch: Add support for newer family of AMD's SOC clk: ingenic: Add MDMA and BDMA clocks dt-bindings: clk/ingenic: Add MDMA and BDMA clocks clk: bm1880: remove kfrees on static allocations clk: Drop unused COMMON_CLK_STM32MP157_SCMI config clk: st: clkgen-mux: search reg within node or parent clk: st: clkgen-fsyn: search reg within node or parent clk: Enable/Disable runtime PM for clk_summary MAINTAINERS: Add entries for Toshiba Visconti PLL and clock controller clk: visconti: Add support common clock driver and reset driver ...

The gcc_aggre1_pnoc_ahb_clk is crucial for the proper MSM8996/APQ8096 functioning. If it gets disabled, several subsytems will stop working (including eMMC/SDCC and USB). There are no in-kernel users of this clock, so it is much simpler to remove from the kernel. The clock was first removed in the commit 9e60de1cf270 ("clk: qcom: Remove gcc_aggre1_pnoc_ahb_clk from msm8996") by Stephen Boyd, but got added back in the commit b567752144e3 ("clk: qcom: Add some missing gcc clks for msm8996") by Rajendra Nayak.

2021-10-14clk: qcom: gdsc: enable optional power domain supportDmitry Baryshkov
On sm8250 dispcc and videocc registers are powered up by the MMCX power domain. Currently we use a regulator to enable this domain on demand, however this has some consequences, as genpd code is not reentrant. Make gdsc code also use pm_runtime calls to ensure that registers are accessible during the gdsc_enable/gdsc_disable operations.

2021-10-13clk: qcom: smd-rpm: Add .recalc_rate hook for clk_smd_rpm_branch_opsShawn Guo
As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can be used by branch clocks to report rate as well, rather than assuming the rate is always same as parent clock. This assumption doesn't hold on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is 19.2MHz. To get this work, XO buffered clocks need the following updates. - Assign a correct rate rather than the fake one which is being used to generate binary value for clk_smd_rpm_req interface. - Explicitly handle the clk_smd_rpm_req interface value for XO buffered clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).
