2025-04-27clk: sunxi: Do not enable by default during compile testingKrzysztof Kozlowski
Enabling the compile test should not cause automatic enabling of all drivers. Restrict the default to ARCH also for individual drivers, even though their choice is not visible without selecting parent Kconfig symbol, because otherwise selecting parent would select the child during compile testing.

2025-04-22clk: renesas: rzv2h: Use both CLK_ON and CLK_MON bits for clock state validationLad Prabhakar
Update the clock enable/disable logic to follow the latest hardware manual's guidelines, ensuring that both CLK_ON and CLK_MON bits are used to confirm the clock state. According to the manual, enabling a clock requires setting the CPG_CLK_ON bit and verifying the clock has started using the CPG_CLK_MON bit. Similarly, disabling a clock requires clearing the CPG_CLK_ON bit and confirming the clock has stopped via the CPG_CLK_MON bit. Modify `rzv2h_mod_clock_is_enabled()` to check CLK_MON first and then validate CLK_ON for a more accurate clock status evaluation.

Unlike dynamic dividers, static dividers do not have a monitor bit. Introduce the `DEF_CSDIV()` macro for defining static dividers, ensuring consistency with existing dynamic divider macros.

2025-04-17clk: spacemit: k1: Add TWSI8 bus and function clocksHaylen Chu
The control register for TWSI8 clocks, APBC_TWSI8_CLK_RST, contains mux selection bits, reset assertion bit and enable bits for function and bus clocks. It has a quirk that reading always results in zero. As a workaround, let's hardcode the mux value as zero to select pll1_d78_31p5 as parent and treat twsi8_clk as a gate, whose enable mask is combined from the real bus and function clocks to avoid the write-only register being shared between two clk_hws, in which case updates of one clk_hw zero the other's bits. With a 1:1 factor serving as placeholder for the bus clock, the I2C-8 controller could be brought up, which is essential for boards attaching power-management chips to it.

2025-04-15clk: qcom: Fix missing error check for dev_pm_domain_attach()Wentao Liang
In the current implementation, the return value of dev_pm_domain_attach() is not checked. This can lead to silent failures if the function fails, as the code would continue execution and return 0, ignoring the error. This patch adds a check for the return value of dev_pm_domain_attach(). If the function fails, an error message is logged using dev_err_probe(), and the error is propagated to the existing error handling path `err`, which ensures proper cleanup by calling clk_notifier_unregister().

Several clocks used by both g12a and g12b use the g12a cpu A clock hw pointer as clock parent. This is incorrect on g12b since the parents of cluster A cpu clock are different. Also the hw clock provided as parent to these children is not even registered clock on g12b.
