Commit 4e197ee880c24ecb63f7fe17449b3653bc64b03c ("clk: imx6ul: add ethernet refclock mux support") sets the internal clock as default ethernet clock. Since IMX6UL_CLK_ENET_REF cannot be parent for IMX6UL_CLK_ENET1_REF_SEL, the call to clk_set_parent() fails. IMX6UL_CLK_ENET1_REF_125M is the correct parent and shall be used instead. Same applies for IMX6UL_CLK_ENET2_REF_SEL, for which IMX6UL_CLK_ENET2_REF_125M is the correct parent.

2024-09-03clk: qcom: gcc-sc8280xp: don't use parking clk_ops for QUPsJohan Hovold
A recent change started parking the RCG at an always on parent during registration, something which specifically breaks handover from an early serial console. Quoting Stephen Boyd who fixed this issue for SM8550 [1]: The QUPs aren't shared in a way that requires parking the RCG at an always on parent in case some other entity turns on the clk. The hardware is capable of setting a new frequency itself with the DFS mode, so parking is unnecessary. Furthermore, there aren't any GDSCs for these devices, so there isn't a possibility of the GDSC turning on the clks for housekeeping purposes. This wasn't a problem to mark these clks shared until we started parking shared RCGs at clk registration time in commit 01a0a6cc8cfd ("clk: qcom: Park shared RCGs upon registration"). Parking at init is actually harmful to the UART when earlycon is used. If the device is pumping out data while the frequency changes you'll see garbage on the serial console until the driver can probe and actually set a proper frequency.

2024-08-30clk: rockchip: rk3588: drop unused codeSebastian Reichel
All clocks are registered early using CLK_OF_DECLARE(), which marks the DT node as processed. For the processed DT node the probe routine is never called. Thus this whole code is never executed. This could be "fixed" by using CLK_OF_DECLARE_DRIVER, which avoids marking the DT node as processed. But then the probe routine would re-register all the clocks by calling rk3588_clk_init() again.

Some clocks maybe default enabled by hardware. For clocks that don't have users, that will be left in hardware default state, because prepare count and enable count is zero,if there is no is_prepared hook to get the hardware state. So add is_prepared hook to detect the hardware state. Then when disabling the unused clocks, they can be simply turned OFF to save power during kernel boot.

Per Stephen Boyd's explanation in the link below, QUP RCG clocks do not need to be parked when switching frequency. A side-effect in parking to a lower frequency can be a momentary invalid clock driven on an in-use serial peripheral. This can cause "junk" to spewed out of a UART as a low-impact example. On the x1e80100-crd this serial port junk can be observed on linux-next. Apply a similar fix to the x1e80100 Global Clock controller to remediate.
