This Patch looks good to me.
Reviewed-by: Tommaso Merciai <tomm.merciai@...il.com>
Tested-by: Tommaso Merciai <tomm.merciai@...il.com>
Note:
I think we can fix also the following defines here, as a coding style
fixes. Maybe in another patch.
#define MAX96714_PATGEN_DE_CNT CCI_REG16(0x25B)
#define MAX96714_PATGEN_CHKB_COLOR_A CCI_REG24(0x25E)
I think hex numbers for regs must be lower case instead of upper case :)
Thanks & Regards,
Tommaso
