Hi Geert, Laurent Gen2 / Gen3 next datasheet will has below note. Our current PFC settings order is MOD_SEL -> GPSR -> IPSR But, this fixes it to MOD_SEL -> IPSR -> GPSR ------------ IPSRx and MOD_SELx registers shall be set before setting GPSRx registers in case that they need to be configured. MOD_SELx registers can be set either earlier or later than setting IPSRx registers. ------------ 1) patch make it easy to check 2) patch fixes above Kuninori Morimoto (2): 1) pinctrl: sh-pfc: enable to indicate GPSR/IPSR/MOD_SEL for debug 2) pinctrl: sh-pfc: IPSRx and MOD_SELx should be set before GPSRx drivers/pinctrl/sh-pfc/core.c | 3 ++- drivers/pinctrl/sh-pfc/sh_pfc.h | 11 +++++++---- 2 files changed, 9 insertions(+), 5 deletions(-) Best regards --- Kuninori Morimoto -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
