Re: [PATCH v4 2/4] leds: aw2013: Add AW2027 support

[sashiko-bot@kernel.org]

> The AW2027 is basically the same as the AW2013.
> 
> It differs in:
> - the max current (30mA rather than 15)
> - the number of current levels for colour-mixing (16 rather than 4)
> - the supply voltage max
> - the charge indicator (unsupported by our driver at this time)
> 
> The max current register (imax) also moves from LCFG to GCR2, and the
> selectable current levels for colour-mixing (LCFG_CUR) take their place.
> 
> The current driver implementation provided here sets the global imax to
> it's maximum, and scales each led to the closest value using the local
> imax. It's the best result achievable short of adding custom sysfs
> entries and mucking up the linux interfaces.
