The clock binding itself doesn't require any specific order, that's what we have the names array for. Is this really what we want? Sascha

Indeed but have in mind that the specific order was there already. This patch does not address that part, only number of clocks. Fixing this for any order could be done with patterns. I can work on that. Best regards, Krzysztof

Driver requires different amount of clocks for different SoCs. Describe these requirements properly to fix dtbs_check warnings like: arch/arm64/boot/dts/freescale/imx8mm-beacon-kit.dt.yaml: nand-controller@33002000: clock-names:1: 'gpmi_apb' was expected Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> --- .../devicetree/bindings/mtd/gpmi-nand.yaml | 76 +++++++++++++++---- 1 file changed, 61 insertions(+), 15 deletions(-)
