PL022 has two input clocks named sspclk and apb_pclk. Current schema refers to two notations of sspclk which are indeed same and thus one can be dropped. Update clock-names property to reflect the same. Signed-off-by:

The minimum array length defaults to the same size as the maximum. For 'mediatek,pad-select', the example has a length of 2 and in-tree .dts files have a length of 1, but the schema says the length must be 4. There's currently no warning in the example because the schema fixups are not handling this case correctly. Signed-off-by:

Commit d40f0b6f instroduced last_cs_enable to avoid setting chipselect if it's not necessary, but it also introduces a bug. The chipselect may not be set correctly on multi-device SPI busses. The reason is that we can't judge the chipselect by bool last_cs_enable, since chipselect may be modified after other devices were accessed. So we should record the specific state of chipselect in case of confusion. Signed-off-by:
