2021-12-02clk: qcom: clk-alpha-pll: Don't reconfigure running TrionBjorn Andersson
In the event that the bootloader has configured the Trion PLL as source for the display clocks, e.g. for the continuous splashscreen, then there will also be RCGs that are clocked by this instance. Reconfiguring, and in particular disabling the output of, the PLL will cause issues for these downstream RCGs and has been shown to prevent them from being re-parented. Follow downstream and skip configuration if it's determined that the PLL is already running.

2021-12-02clk: qcom: regmap-mux: fix parent clock lookupDmitry Baryshkov
The function mux_get_parent() uses qcom_find_src_index() to find the parent clock index, which is incorrect: qcom_find_src_index() uses src enum for the lookup, while mux_get_parent() should use cfg field (which corresponds to the register value). Add qcom_find_cfg_index() function doing this kind of lookup and use it for mux parent lookup.

2021-11-05clk: qcom: gcc-msm8996: Drop (again) gcc_aggre1_pnoc_ahb_clkDmitry Baryshkov
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. Let's remove it again in hope that nobody adds it back.

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).

2021-09-14clk: qcom: gcc-msm8998: Remove transient global "xo" clockMarijn Suijten
Now that all clock controllers and the DSI PLL clocks rely on "xo" being passed in DT as phandle instead of looking it up by the global "xo" name this transient clock can be removed, leaving only the fixed-factor "xo_board" clock in DT.

2021-09-14clk: qcom: gcc-msm8998: Use parent_data/hws for internal clock relationsMarijn Suijten
Use parent_data and parent_hws to specify internal relations using pointers instead of names, and use .fw_name to retrieve external clocks from clock-names in the DT rather than the global clock tree. Note that this change relies on the "xo" and "sleep_clk" clocks to be provided in DT, as per the relevant qcom,gcc-mnsm8998.yaml dt-bindings. These clocks have been added in a prior patch [1].

Prepare for a future patch where we use .hw pointers to these GPLL clocks in the parent mapping instead of name references. This requires the GPLL clocks to be decared before parent_data arrays.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Nothing changed in the clk framework core this time around. We did get some updates to the basic clk types to use determine_rate for the divider type and add a power of two fractional divider flag though. Otherwise, this is a collection of clk driver updates. More than half the diffstat is in the Qualcomm clk driver where we add a bunch of data to describe clks on various SoCs and fix bugs. The other big new thing in here is the Mediatek MT8192 clk driver. That's been under review for a while and it's nice to see that it's finally upstream. Beyond that it's the usual set of minor fixes and tweaks to clk drivers. There are some non-clk driver bits in here which have all been acked by the respective maintainers. New Drivers: - Support video, gpu, display clks on qcom sc7280 SoCs - GCC clks on qcom MSM8953, SM4250/6115, and SM6350 SoCs - Multimedia clks (MMCC) on qcom MSM8994/MSM8992 - RPMh clks on qcom SM6350 SoCs - Support for Mediatek MT8192 SoCs - Add display (DU and DSI) clocks on Renesas R-Car V3U - Add I2C, DMAC, USB, sound (SSIF-2), GPIO, CANFD, and ADC clocks and resets on Renesas RZ/G2L Updates: - Support the SD/OE pin on IDT VersaClock 5 and 6 clock generators - Add power of two flag to fractional divider clk type - Migrate some clk drivers to clk_divider_ops.determine_rate - Migrate to clk_parent_data in gcc-sdm660 - Fix CLKOUT clocks on i.MX8MM and i.MX8MN by using imx_clk_hw_mux2 - Switch from .round_rate to .determine_rate in clk-divider-gate - Fix clock tree update for TF-A controlled clocks for all i.MX8M - Add missing M7 core clock for i.MX8MN - YAML conversion of rk3399 clock controller binding - Removal of GRF dependency for the rk3328/rk3036 pll types - Drop CLK_IS_CRITICAL flag from Tegra fuse clk - Make CLK_R9A06G032 Kconfig symbol invisible - Convert various DT bindings to YAML" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (128 commits) dt-bindings: clock: samsung: fix header path in example clk: tegra: fix old-style declaration clk: qcom: Add SM6350 GCC driver MAINTAINERS: clock: include S3C and S5P in Samsung SoC clock entry dt-bindings: clock: samsung: convert S5Pv210 AudSS to dtschema dt-bindings: clock: samsung: convert Exynos AudSS to dtschema dt-bindings: clock: samsung: convert Exynos4 to dtschema dt-bindings: clock: samsung: convert Exynos3250 to dtschema dt-bindings: clock: samsung: convert Exynos542x to dtschema dt-bindings: clock: samsung: add bindings for Exynos external clock dt-bindings: clock: samsung: convert Exynos5250 to dtschema clk: vc5: Add properties for configuring SD/OE behavior clk: vc5: Use dev_err_probe dt-bindings: clk: vc5: Add properties for configuring the SD/OE pin dt-bindings: clock: brcm,iproc-clocks: fix armpll properties clk: zynqmp: Fix kernel-doc format clk: at91: clk-generated: Limit the requested rate to our range clk: ralink: avoid to set 'CLK_IS_CRITICAL' flag for gates clk: zynqmp: Fix a memory leak clk: zynqmp: Check the return type ...

Commit 5658e8cf1a8a ("clk: qcom: add video clock controller driver for SM8150") and commit 0e94711a1f29 ("clk: qcom: add video clock controller driver for SM8250") add config SM_VIDEOCC_8150 and config SM_VIDEOCC_8250, which select the non-existing configs SDM_GCC_8150 and SDM_GCC_8250, respectively. Hence, ./scripts/checkkconfigsymbols.py warns: SDM_GCC_8150 Referencing files: drivers/clk/qcom/Kconfig SDM_GCC_8250 Referencing files: drivers/clk/qcom/Kconfig It is probably just a typo (or naming confusion of using SM_GCC_xxx and SDM_GCC_xxx for various Qualcomm clock drivers) in the config definitions for config SM_VIDEOCC_8150 and SM_VIDEOCC_8250, and intends to select the existing SM_GCC_8150 and SM_GCC_8250, respectively.
