Yes, I also wondered about the second issue you are mentioning when I was
fixing the main problem. But since Xiubo's patch also set
REGMAP_ENDIAN_BIG as default for both the I2C and SPI buses (making no
difference as you said) I assumed that the intention was to make buses to
explicitly define their default instead of rely on a global one so I just
kept that way.
But I agree with you that is better to go back to the default
REGMAP_ENDIAN_BIG as it used to be before since buses can change the
default if needed anyways.
Best regards,
Javier
