Thu, 02 Apr 2026 13:27:06 +0200

soc: renesas: Add Renesas R-Car MFIS driverRenesas R-Car MFIS offers multiple features but most importantlymailboxes and hwspinlocks. Because they share a common register spaceand a common register unprotection mechanism, a single driver was chosento handle all dependencies. (MFD and auxiliary bus have been tried aswell, but they failed because of circular dependencies.)In this first step, the driver implements common register access and amailbox controller. hwspinlock support will be added incrementally, oncethe subsystem allows out-of-directory drivers.Signed-off-by: Kuninori Morimoto Signed-off-by: Wolfram Sang Acked-by: Jassi Brar Reviewed-by: Geert Uytterhoeven Tested-by: Geert Uytterhoeven Link: https://patch.msgid.link/20260402112709.13002-3-wsa+renesas@sang-engineering.comSigned-off-by: Geert Uytterhoeven List of files: /linux/drivers/soc/renesas/Kconfig
