| |
Due to an interaction with commit 9f2b76a2db3c4387 ("pinctrl: sh-pfc: r8a77990: Add R8A774C0 PFC support"), the state of the I/O Control Registers is saved/restored during s2ram on RZ/G2E, but not on R-Car E3. Hence on R-Car E3, SDHI voltage state is lost after system resume.
Fix this by registering the I/O Control Registers on R-Car E3, too.
Fixes: 33847a71373cd6ae ("pinctrl: sh-pfc: r8a77990: Add voltage switch operations for SDHI") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- To be queued as a fix in sh-pfc-for-v4.21.
