From d5099bc1b56417733f4cccf10c61ee74dadd5562 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Mon, 24 Mar 2025 19:51:29 +0800 Subject: [PATCH] ASoC: codec: wcd9335: Convert to GPIO descriptors of_gpio.h is deprecated, update the driver to use GPIO descriptors. - Use dev_gpiod_get to get GPIO descriptor. - Use gpiod_set_value to configure output value. With legacy of_gpio API, the driver set gpio value 0 to assert reset, and 1 to deassert reset. And the reset-gpios use GPIO_ACTIVE_LOW flag in DTS, so set GPIOD_OUT_LOW when get GPIO descriptors, and set value 1 means output low, set value 0 means output high with gpiod API. The in-tree DTS files have the right polarity set up already so we can expect this to "just work" Reviewed-by: Linus Walleij Signed-off-by: Peng Fan Link: https://patch.msgid.link/20250324-wcd-gpiod-v2-3-773f67ce3b56@nxp.com Reviewed-by: Bartosz Golaszewski Signed-off-by: Mark Brown --- sound/soc/codecs/wcd9335.c | 15 +++++++-------- 1 file changed, 7 insertions(+), 8 deletions(-) diff --git a/sound/soc/codecs/wcd9335.c b/sound/soc/codecs/wcd9335.c index 7cef43bb2a88..8ee4360aff92 100644 --- a/sound/soc/codecs/wcd9335.c +++ b/sound/soc/codecs/wcd9335.c @@ -17,7 +17,7 @@ #include #include #include -#include +#include #include #include #include @@ -331,7 +331,7 @@ struct wcd9335_codec { int comp_enabled[COMPANDER_MAX]; int intr1; - int reset_gpio; + struct gpio_desc *reset_gpio; struct regulator_bulk_data supplies[WCD9335_MAX_SUPPLY]; unsigned int rx_port_value[WCD9335_RX_MAX]; @@ -4975,12 +4975,11 @@ static const struct regmap_irq_chip wcd9335_regmap_irq1_chip = { static int wcd9335_parse_dt(struct wcd9335_codec *wcd) { struct device *dev = wcd->dev; - struct device_node *np = dev->of_node; int ret; - wcd->reset_gpio = of_get_named_gpio(np, "reset-gpios", 0); - if (wcd->reset_gpio < 0) - return dev_err_probe(dev, wcd->reset_gpio, "Reset GPIO missing from DT\n"); + wcd->reset_gpio = devm_gpiod_get(dev, "reset", GPIOD_OUT_LOW); + if (IS_ERR(wcd->reset_gpio)) + return dev_err_probe(dev, PTR_ERR(wcd->reset_gpio), "Reset GPIO missing from DT\n"); wcd->mclk = devm_clk_get(dev, "mclk"); if (IS_ERR(wcd->mclk)) @@ -5023,9 +5022,9 @@ static int wcd9335_power_on_reset(struct wcd9335_codec *wcd) */ usleep_range(600, 650); - gpio_direction_output(wcd->reset_gpio, 0); + gpiod_set_value(wcd->reset_gpio, 1); msleep(20); - gpio_set_value(wcd->reset_gpio, 1); + gpiod_set_value(wcd->reset_gpio, 0); msleep(20); return 0; -- 2.50.1
