Does adding this patch without > its dependency cause a regression? Since the SDHI2 pins definition contain "power-source" property, adding this patch without its dependency will cause an error at boot up as the kernel would be looking for flag SH_PFC_PIN_CFG_IO_VOLTAGE for each pin contained in sdhi2_pins and sdhi2_pins_uhs, and since that particular flag would be missing (as such a definition comes from patch "pinctrl: sh-pfc: r8a77470: Add SDHI2 voltage switch") the SD card would not be functional, but this won't have any impact on the rest of the system. > > > Shall I re-send it at a later stage or are you happy to keep it around > > and defer its application to when its dependency is sorted? > > I'd rather that you repost or otherwise ping me once any dependency is sorted. Ok, I will do that. Thanks, Fab Renesas Electronics Europe Ltd, Dukes Meadow, Millboard Road, Bourne End, Buckinghamshire, SL8 5FH, UK. Registered in England & Wales under Registered No. 04586709.
