clk: qcom: gcc-sdm660: Use floor ops for SDCC1 clock

2022-08-29T20:55:57Z

In commit 3f905469c8ce ("clk: qcom: gcc: Use floor ops for SDCC clocks") floor ops were applied to SDCC2 only, but flooring is also required on the SDCC1 apps clock which is used by the eMMC card on Sony's Nile platform, and otherwise result in the typicial "Card appears overclocked" warnings observed on many other platforms before: mmc0: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz mmc0: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz mmc0: Card appears overclocked; req 104000000 Hz, actual 192000000 Hz Fixes: f2a76a2955c0 ("clk: qcom: Add Global Clock controller (GCC) driver for SDM660") Signed-off-by: Marijn Suijten Tested-by: Alexey Minnekhanov Reviewed-by: Stephen Boyd Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20220714203822.186448-1-marijn.suijten@somainline.org

clk: qcom: gcc-sdm660: Use ARRAY_SIZE for num_parents

2021-09-14T21:09:47Z

Where possible, use ARRAY_SIZE to determine the number of parents in clk_parent_data instead of hardcoding a number that relies on an array defined hundreds of lines above.

clk: qcom: gcc-sdm660: Replace usage of parent_names

2021-08-26T18:51:11Z

Using parent_data and parent_hws, instead of parent_names, does protect against some cases of incompletely defined clock trees. While it turns out that the bug being chased this time was totally unrelated, this patch converts the SDM660 GCC driver to avoid such issues. The "xo" fixed_factor clock is unused within the gcc driver, but referenced from the DSI PHY. So it's left in place until the DSI driver is updated.

clk: qcom: gcc-sdm660: Move parent tables after PLLs

2021-08-26T18:49:14Z

In the next patch we're going to change these tables to reference the PLL structures directly. Let's move them here so the diff is easier to read. No functional change in this patch. Signed-off-by: Stephen Boyd

clk: qcom: gcc-sdm660: Mark GPU CFG AHB clock as critical

2021-02-14T20:56:54Z

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.

2021-02-14T20:56:54Z

Similarly to MSM8998, any access to the MMSS depends on this clock. Gating it will crash the system when RPMCC inits mmssnoc_axi_rpm_clk.
