sc589-ezkit.dts: fix dtc warnings #4

Closed twoerner closed 1 year ago

twoerner commented 2 years ago

The dtc throws the following warnings when compiling the dts for the sc589-ezkit (for both the SPL and U-Boot proper):

arch/arm/dts/sc589-ezkit.dtb: Warning (reg_format): /soc/i2c2@31001600/mcp23017@21:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

The fixes involve explicitly setting the #address-cells and #size-cells values.
