SubjectRe: [PATCH 0/4][RFC] regmap: add force write option
Date

Hi Mark

Can I have some feedback about these patches ?

> Current _regmap_update_bits() writes data to register if current value and
> write value was different. This means it doesn't write data if the value was
> same as current value.
> But, some device needs to write data even though it was same value.
>
> This RFC patch-set adds new "force_write" option on _regmap_update_bits()
> for this issue, but it focuses only 1 regmap write function at this point,
> because there are many regmap_xxx_write_yyy() functions.
> I can care all of regmap_xxx_write_yyy() functions in formal patch-set if
> this RFC patch idea was OK.
