And the power domain, as this is for i2c-sh_mobile.c.
On SH/R-Mobile SoCs, the i2c block is part of a power area.
Most are part of A3SP (which is never really disabled due to being
shared with other devices), or C5 (always-on), but i2c0 on R-Mobile A1
is part of A4R, which is usually suspended.
Uli: can you check if atomic transfers work with the touchscreen or
codec on Armadillo-800-EVA?
Thanks!
