nand-controller@8000c000 {
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> --- Changes since v3: 1. Go back to fixed order of clocks, after explanation from Rob. Changes since v1: 1. Do not require order of clocks (use pattern). --- .../devicetree/bindings/mtd/gpmi-nand.yaml | 76 +++++++++++++++---- 1 file changed, 61 insertions(+), 15 deletions(-)
