Add it to the pinctrl driver. Signed-off-by: LUU HOAI Signed-off-by: Wolfram Sang Reported-by: kernel test robot --- Original BSP commit: f479c5a4e5e5 ("pinctrl: renesas: r8a77990: Add driver-strength for R8A77990") However, this was incomplete and missed 6 pins of table 6D.6 which were on a separate page. Adding them simplifies PORT_GP updates a lot. However, a preparational patch is needed then which is patch 1 of this series. drivers/pinctrl/renesas/pfc-r8a77990.c | 38 ++++++++++++++++++++++++-- 1 file changed, 36 insertions(+), 2 deletions(-) diff --git a/drivers/pinctrl/renesas/pfc-r8a77990.c b/drivers/pinctrl/renesas/pfc-r8a77990.c index f44c7da3ec16..cc825100f2fe 100644 --- a/drivers/pinctrl/renesas/pfc-r8a77990.c +++ b/drivers/pinctrl/renesas/pfc-r8a77990.c @@ -22,12 +22,12 @@ PORT_GP_CFG_18(0, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_23(1, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_26(2, fn, sfx, CFG_FLAGS), \ - PORT_GP_CFG_12(3, fn, sfx, CFG_FLAGS | SH_PFC_PIN_CFG_IO_VOLTAGE), \ + PORT_GP_CFG_12(3, fn, sfx, CFG_FLAGS | SH_PFC_PIN_CFG_IO_VOLTAGE | SH_PFC_PIN_CFG_DRIVE_STRENGTH), \ PORT_GP_CFG_1(3, 12, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_1(3, 13, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_1(3, 14, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_1(3, 15, fn, sfx, CFG_FLAGS), \ - PORT_GP_CFG_11(4, fn, sfx, CFG_FLAGS | SH_PFC_PIN_CFG_IO_VOLTAGE), \ + PORT_GP_CFG_11(4, fn, sfx, CFG_FLAGS | SH_PFC_PIN_CFG_IO_VOLTAGE | SH_PFC_PIN_CFG_DRIVE_STRENGTH), \ PORT_GP_CFG_20(5, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_9(6, fn, sfx, CFG_FLAGS), \ PORT_GP_CFG_1(6, 9, fn, sfx, SH_PFC_PIN_CFG_PULL_UP), \ @@ -5104,6 +5104,39 @@ static const struct pinmux_cfg_reg pinmux_config_regs[] = { { }, }; +static const struct pinmux_drive_reg pinmux_drive_regs[] = { + { PINMUX_DRIVE_REG("DRVCTRL8", 0xe6060320) { + { RCAR_GP_PIN(3, 0), 18, 2 }, /* SD0_CLK */ + { RCAR_GP_PIN(3, 1), 15, 2 }, /* SD0_CMD */ + { RCAR_GP_PIN(3, 2), 12, 2 }, /* SD0_DAT0 */ + { RCAR_GP_PIN(3, 3), 9, 2 }, /* SD0_DAT1 */ + { RCAR_GP_PIN(3, 4), 6, 2 }, /* SD0_DAT2 */ + { RCAR_GP_PIN(3, 5), 3, 2 }, /* SD0_DAT3 */ + { RCAR_GP_PIN(3, 6), 0, 2 }, /* SD1_CLK */ + } }, + { PINMUX_DRIVE_REG("DRVCTRL9", 0xe6060324) { + { RCAR_GP_PIN(3, 7), 29, 2 }, /* SD1_CMD */ + { RCAR_GP_PIN(3, 8), 26, 2 }, /* SD1_DAT0 */ + { RCAR_GP_PIN(3, 9), 23, 2 }, /* SD1_DAT1 */ + { RCAR_GP_PIN(3, 10), 20, 2 }, /* SD1_DAT2 */ + { RCAR_GP_PIN(3, 11), 17, 2 }, /* SD1_DAT3 */ + { RCAR_GP_PIN(4, 0), 14, 2 }, /* SD3_CLK */ + { RCAR_GP_PIN(4, 1), 11, 2 }, /* SD3_CMD */ + { RCAR_GP_PIN(4, 2), 8, 2 }, /* SD3_DAT0 */ + { RCAR_GP_PIN(4, 3), 5, 2 }, /* SD3_DAT1 */ + { RCAR_GP_PIN(4, 4), 2, 2 }, /* SD3_DAT2 */ + } }, + { PINMUX_DRIVE_REG("DRVCTRL10", 0xe6060328) { + { RCAR_GP_PIN(4, 5), 29, 2 }, /* SD3_DAT3 */ + { RCAR_GP_PIN(4, 6), 26, 2 }, /* SD3_DAT4 */ + { RCAR_GP_PIN(4, 7), 23, 2 }, /* SD3_DAT5 */ + { RCAR_GP_PIN(4, 8), 20, 2 }, /* SD3_DAT6 */ + { RCAR_GP_PIN(4, 9), 17, 2 }, /* SD3_DAT7 */ + { RCAR_GP_PIN(4, 10), 14, 2 }, /* SD3_DS */ + } }, + { }, +}; + enum ioctrl_regs { POCCTRL0, TDSELCTRL, @@ -5387,6 +5420,7 @@ const struct sh_pfc_soc_info r8a77990_pinmux_info = { ARRAY_SIZE(pinmux_functions.automotive), .cfg_regs = pinmux_config_regs, + .drive_regs = pinmux_drive_regs, .bias_regs = pinmux_bias_regs, .ioctrl_regs = pinmux_ioctrl_regs,
