Hi, Andre', I played with SPI and noticed that we have to propagate some clock rates to parents here. If you don't play with all the peripherals from the block you can't know what to propagate. So I think it's fine to not handle this topic right now. I'll come with a patch on top of yours when I finish the SPI validation. The patch is looking fine. I'll finish reviewing the series after v2 is out. Cheers, ta

CMU_PERIC1 is the clock management unit used for the peric1 block which is used for additional USI, I3C and PWM interfaces/busses. Add support for muxes, dividers and gates of cmu_peric1, except for CLK_GOUT_PERIC1_IP which isn't well described in the datasheet and which downstream also ignores (similar to cmu_peric0). Two clocks have been marked as CLK_IS_CRITICAL for the following reason: * disabling them makes it impossible to access any peric1 registers, (including those two registers). * disabling gout_peric1_lhm_axi_p_peric1_i_clk sometimes has the additional effect of making the whole system unresponsive. The clocks marked as CLK_IGNORE_UNUSED need to be kept on until we have updated the respective drivers for the following reasons: * gout_peric1_gpio_peric1_pclk is required by the pinctrl configuration. With this clock disabled, reconfiguring the pins (for USI/I2C, USI/UART) will hang during register access. Since pingctrl-samsung doesn't support a clock at the moment, we just keep the kernel from disabling it at boot, until we have an update for samsung-pinctrl, at which point we'll drop the flag. * gout_peric1_sysreg_peric1_pclk needs to be hooked up to sysreg_peric1 in DT which will be done in a followup-patch, at which point we'll drop the special treatment from here. We're adding the flag temporarily here so as to not break the boot (due to pclk otherwise getting disabled).
