In case the pin had more than one configuration, even if -we set the slew rate as disabled in the device tree, the next pin -configuration would set again the slew rate enabled by default, -overwriting the slew rate disablement. -Instead of enabling the slew rate by default for each pin configuration, -enable the slew rate by default just once per pin, regardless of the -number of configurations. This way the slew rate disablement will also -work for cases where pins have multiple configurations. - -Fixes: c709135e576b ("pinctrl: at91-pio4: add support for slew-rate") -Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> -Reviewed-by: Claudiu Beznea <claudiu.beznea@microchip.com> -Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com> -Link: https://lore.kernel.org/r/20210409082522.625168-1-tudor.ambarus@microchip.com -Signed-off-by: Linus Walleij <linus.walleij@linaro.org> ---- - drivers/pinctrl/pinctrl-at91-pio4.c | 8 ++++---- - 1 file changed, 4 insertions(+), 4 deletions(-) - ---- a/drivers/pinctrl/pinctrl-at91-pio4.c -+++ b/drivers/pinctrl/pinctrl-at91-pio4.c -@@ -801,6 +801,10 @@ static int atmel_conf_pin_config_group_s - - conf = atmel_pin_config_read(pctldev, pin_id); - -+ /* Keep slew rate enabled by default. */ -+ if (atmel_pioctrl->slew_rate_support) -+ conf |= ATMEL_PIO_SR_MASK; -+ - for (i = 0; i < num_configs; i++) { - unsigned int param = pinconf_to_config_param(configs[i]); - unsigned int arg = pinconf_to_config_argument(configs[i]); -@@ -808,10 +812,6 @@ static int atmel_conf_pin_config_group_s - dev_dbg(pctldev->dev, "%s: pin=%u, config=0x%lx\n", - __func__, pin_id, configs[i]); - -- /* Keep slew rate enabled by default. */ -- if (atmel_pioctrl->slew_rate_support) -- conf |= ATMEL_PIO_SR_MASK; -- - switch (param) { - case PIN_CONFIG_BIAS_DISABLE: - conf &= (~ATMEL_PIO_PUEN_MASK); |
