If rx8xx needed to be different from rk808, I'd have a different opinion but that is not the case here. > Signed-off-by: Wadim Egorov <w.egorov@phytec.de> > --- > drivers/clk/clk-rk808.c | 20 +++++++-------- > drivers/mfd/rk808.c | 36 +++++++++++++------------- > drivers/regulator/rk808-regulator.c | 8 +++--- > drivers/rtc/rtc-rk808.c | 50 ++++++++++++++++++------------------- > include/linux/mfd/rk808.h | 2 +- > 5 files changed, 58 insertions(+), 58 deletions(-) > > diff --git a/drivers/clk/clk-rk808.c b/drivers/clk/clk-rk808.c > index 0fee2f4..6df2e72 100644 > --- a/drivers/clk/clk-rk808.c > +++ b/drivers/clk/clk-rk808.c > @@ -25,7 +25,7 @@ > #define RK808_NR_OUTPUT 2 > > struct rk808_clkout { > - struct rk808 *rk808; > + struct rk8xx *rk8xx; > struct clk_onecell_data clk_data; > struct clk_hw clkout1_hw; > struct clk_hw clkout2_hw; > @@ -42,9 +42,9 @@ static int rk808_clkout2_enable(struct clk_hw *hw, bool enable) > struct rk808_clkout *rk808_clkout = container_of(hw, > struct rk808_clkout, > clkout2_hw); > - struct rk808 *rk808 = rk808_clkout->rk808; > + struct rk8xx *rk8xx = rk808_clkout->rk8xx; > > - return regmap_update_bits(rk808->regmap, RK808_CLK32OUT_REG, > + return regmap_update_bits(rk8xx->regmap, RK808_CLK32OUT_REG, > CLK32KOUT2_EN, enable ?
