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.

2021-08-26clk: qcom: gcc-sdm660: Replace usage of parent_namesBjorn Andersson
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.

When configuring a kernel including support for Renesas ARM/ARM64 Socs, but excluding support for the RZ/N1D SoC, the user is always asked about the RZ/N1D clock driver. As this driver is already auto-selected when building a kernel including support for the RZ/N1D SoC, there is no need to make the CLK_R9A06G032 symbol visible, unless compile-testing. Align the symbol description with the other symbols.

That said, a53pll/mux clock needs to be named uniquely. Append @unit-address of device node to the clock name, so that a53pll/mux will be named like below on MSM8939. a53pll@b016000 a53pll@b116000 a53pll@b1d0000 a53mux@b1d1000 a53mux@b011000 a53mux@b111000 Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Link: https://lore.kernel.org/r/20210704024032.11559-3-shawn.guo@linaro.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2021-08-05clk: divider: Implement and wire up .determine_rate by defaultMartin Blumenstingl
.determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz). Implement .determine_rate in addition to .round_rate so drivers that are using clk_divider_{ro_,}ops can benefit from this by default. Keep the .round_rate callback for now since some drivers rely on clk_divider_ops.round_rate being implemented.

2021-08-05clk: Align provider-specific CLK_* bit definitionsGeert Uytterhoeven
The definition of CLK_MULTIPLIER_ROUND_CLOSEST is not aligned to the two bit definitions next to it. A deeper inspection reveals that the alignment of CLK_MULTIPLIER_ROUND_CLOSEST does match the most common alignment. Align the bit definitions for the various provider types throughout the file at 40 columns, to increase uniformity.

I found that COMMON_CLK_MT8167* do not depend on COMMON_CLK_MT8167, so it is possible to config: CONFIG_COMMON_CLK_MT8167=n CONFIG_COMMON_CLK_MT8167_*=y Although it does not cause build breaks with such configuration, I think it is clearer to make COMMON_CLK_MT8167* depend on COMMON_CLK_MT8167.
