Message-ID: <1979633.oxsqSuXO5u@wasted.cogentembedded.com> (raw)
In-Reply-To: <1987532.PE2ex6PrJ5@wasted.cogentembedded.com>
Add support for RZ/G1M (R8A7743) SoC power areas to the R-Car SYSC driver.
Based on the original (and large) patch by Dmitry Shifrin
<dmitry.shifrin@cogentembedded.com>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>
