Acked-by: Lee Jones <lee.jo...@linaro.org> Signed-off-by: Keerthy <j-keer...@ti.com> --- Changes in v6: Rebased against linux-next + https://lkml.org/lkml/2016/6/24/122 series. Changes in v4: * Added Lee Jones's Ack. Changes in v3: * Cleaned up tps65218-pwrbutton and gpio drivers to remove tps65218_reg_read instances. drivers/gpio/gpio-tps65218.c | 3 ++- drivers/input/misc/tps65218-pwrbutton.c | 3 ++- drivers/mfd/tps65218.c | 18 ++---------------- drivers/regulator/tps65218-regulator.c | 5 +++-- include/linux/mfd/tps65218.h | 2 -- 5 files changed, 9 insertions(+), 22 deletions(-) diff --git a/drivers/gpio/gpio-tps65218.c b/drivers/gpio/gpio-tps65218.c index 0eaeac8..0f9d9bd 100644 --- a/drivers/gpio/gpio-tps65218.c +++ b/drivers/gpio/gpio-tps65218.c @@ -16,6 +16,7 @@ #include <linux/errno.h> #include <linux/gpio/driver.h> #include <linux/platform_device.h> +#include <linux/regmap.h> #include <linux/mfd/tps65218.h> struct tps65218_gpio { @@ -30,7 +31,7 @@ static int tps65218_gpio_get(struct gpio_chip *gc, unsigned offset) unsigned int val; int ret; - ret = tps65218_reg_read(tps65218, TPS65218_REG_ENABLE2, &val); + ret = regmap_read(tps65218->regmap, TPS65218_REG_ENABLE2, &val); if (ret) return ret; diff --git a/drivers/input/misc/tps65218-pwrbutton.c b/drivers/input/misc/tps65218-pwrbutton.c index a39b626..2bba8de 100644 --- a/drivers/input/misc/tps65218-pwrbutton.c +++ b/drivers/input/misc/tps65218-pwrbutton.c @@ -22,6 +22,7 @@ #include <linux/module.h> #include <linux/of.h> #include <linux/platform_device.h> +#include <linux/regmap.h> #include <linux/slab.h> struct tps65218_pwrbutton { @@ -36,7 +37,7 @@ static irqreturn_t tps65218_pwr_irq(int irq, void *_pwr) unsigned int reg; int error; - error = tps65218_reg_read(pwr->tps, TPS65218_REG_STATUS, ®); + error = regmap_read(pwr->tps->regmap, TPS65218_REG_STATUS, ®); if (error) { dev_err(pwr->dev, "can't read register: %d\n", error); goto out; diff --git a/drivers/mfd/tps65218.c b/drivers/mfd/tps65218.c index ba610ad..9bca1b1 100644 --- a/drivers/mfd/tps65218.c +++ b/drivers/mfd/tps65218.c @@ -34,20 +34,6 @@ #define TPS65218_PASSWORD_REGS_UNLOCK 0x7D /** - * tps65218_reg_read: Read a single tps65218 register. - * - * @tps: Device to read from. - * @reg: Register to read. - * @val: Contians the value - */ -int tps65218_reg_read(struct tps65218 *tps, unsigned int reg, - unsigned int *val) -{ - return regmap_read(tps->regmap, reg, val); -} -EXPORT_SYMBOL_GPL(tps65218_reg_read); - -/** * tps65218_reg_write: Write a single tps65218 register. * * @tps65218: Device to write to. @@ -93,7 +79,7 @@ static int tps65218_update_bits(struct tps65218 *tps, unsigned int reg, int ret; unsigned int data; - ret = tps65218_reg_read(tps, reg, &data); + ret = regmap_read(tps->regmap, reg, &data); if (ret) { dev_err(tps->dev, "Read from reg 0x%x failed\n", reg); return ret; @@ -251,7 +237,7 @@ static int tps65218_probe(struct i2c_client *client, if (ret < 0) return ret; - ret = tps65218_reg_read(tps, TPS65218_REG_CHIPID, &chipid); + ret = regmap_read(tps->regmap, TPS65218_REG_CHIPID, &chipid); if (ret) { dev_err(tps->dev, "Failed to read chipid: %d\n", ret); return ret; diff --git a/drivers/regulator/tps65218-regulator.c b/drivers/regulator/tps65218-regulator.c index eb0f5b1..ae16caf 100644 --- a/drivers/regulator/tps65218-regulator.c +++ b/drivers/regulator/tps65218-regulator.c @@ -22,6 +22,7 @@ #include <linux/err.h> #include <linux/platform_device.h> #include <linux/of_device.h> +#include <linux/regmap.h> #include <linux/regulator/of_regulator.h> #include <linux/regulator/driver.h> #include <linux/regulator/machine.h> @@ -272,7 +273,7 @@ static int tps65218_pmic_get_current_limit(struct regulator_dev *dev) unsigned int index; struct tps65218 *tps = rdev_get_drvdata(dev); - retval = tps65218_reg_read(tps, dev->desc->csel_reg, &index); + retval = regmap_read(tps->regmap, dev->desc->csel_reg, &index); if (retval < 0) return retval; @@ -383,7 +384,7 @@ static int tps65218_regulator_probe(struct platform_device *pdev) return PTR_ERR(rdev); } - ret = tps65218_reg_read(tps, regulators[id].bypass_reg, &val); + ret = regmap_read(tps->regmap, regulators[id].bypass_reg, &val); if (ret) return ret; diff --git a/include/linux/mfd/tps65218.h b/include/linux/mfd/tps65218.h index d1db952..51bef53 100644 --- a/include/linux/mfd/tps65218.h +++ b/include/linux/mfd/tps65218.h @@ -284,8 +284,6 @@ struct tps65218 { struct regmap *regmap; }; -int tps65218_reg_read(struct tps65218 *tps, unsigned int reg, - unsigned int *val); int tps65218_reg_write(struct tps65218 *tps, unsigned int reg, unsigned int val, unsigned int level); int tps65218_set_bits(struct tps65218 *tps, unsigned int reg, -- 1.9.1
