Signed-off-by: Satya Priya Reviewed-by: Stephen Boyd --- Changes in V12: - Move reset_gpio acquiring above probe_irq_peripherals in pm8008_probe. Changes in V11: - Use local variable for reset_gpios as it is not used outside of probe. - Use GPIOD_OUT_LOW flag to initialize the gpio and remove below line as it is not required "gpiod_set_value(chip->reset_gpio, 1);". Changes in V10: - This has been split from [V9,3/6] as per comments here [1] [1] https://patchwork.kernel.org/project/linux-arm-msm/patch/1649166633-25872-4-git-send-email-quic_c_skakit@quicinc.com/#24803409 drivers/mfd/qcom-pm8008.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/mfd/qcom-pm8008.c b/drivers/mfd/qcom-pm8008.c index c472d7f..5a670b0 100644 --- a/drivers/mfd/qcom-pm8008.c +++ b/drivers/mfd/qcom-pm8008.c @@ -4,6 +4,7 @@ */ #include +#include #include #include #include @@ -221,6 +222,7 @@ static int pm8008_probe(struct i2c_client *client) { int rc; struct pm8008_data *chip; + struct gpio_desc *reset_gpio; chip = devm_kzalloc(&client->dev, sizeof(*chip), GFP_KERNEL); if (!chip) @@ -233,6 +235,10 @@ static int pm8008_probe(struct i2c_client *client) i2c_set_clientdata(client, chip); + reset_gpio = devm_gpiod_get(chip->dev, "reset", GPIOD_OUT_LOW); + if (IS_ERR(reset_gpio)) + return PTR_ERR(reset_gpio); + if (of_property_read_bool(chip->dev->of_node, "interrupt-controller")) { rc = pm8008_probe_irq_peripherals(chip, client->irq); if (rc)
