Fix the +iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is +correctly increased by 8, matching the actual width of GPIO2-B iomux. + +Fixes: e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins") +Cc: stable@vger.kernel.org +Reported-by: Richard Kojedzinszky +Closes: https://lore.kernel.org/linux-rockchip/4f29b743202397d60edfb3c725537415@kojedz.in/ +Tested-by: Richard Kojedzinszky +Signed-off-by: Huang-Huang Bao +Reviewed-by: Heiko Stuebner +Tested-by: Daniel Golle +Tested-by: Trevor Woerner +Link: https://lore.kernel.org/20240709105428.1176375-1-i@eh5.me +Signed-off-by: Linus Walleij +Signed-off-by: Greg Kroah-Hartman +--- + drivers/pinctrl/pinctrl-rockchip.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/drivers/pinctrl/pinctrl-rockchip.c b/drivers/pinctrl/pinctrl-rockchip.c +index b02eaba010d101..b5a02335617d77 100644 +--- a/drivers/pinctrl/pinctrl-rockchip.c ++++ b/drivers/pinctrl/pinctrl-rockchip.c +@@ -3802,7 +3802,7 @@ static struct rockchip_pin_bank rk3328_pin_banks[] = { + PIN_BANK_IOMUX_FLAGS(0, 32, "gpio0", 0, 0, 0, 0), + PIN_BANK_IOMUX_FLAGS(1, 32, "gpio1", 0, 0, 0, 0), + PIN_BANK_IOMUX_FLAGS(2, 32, "gpio2", 0, +- 0, ++ IOMUX_WIDTH_2BIT, + IOMUX_WIDTH_3BIT, + 0), + PIN_BANK_IOMUX_FLAGS(3, 32, "gpio3", +-- +cgit 1.2.3-korg +
