From f510c32a6af6123bc0638bfe869728bf8be71027 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Mon, 12 Feb 2018 15:58:39 +0100 Subject: [PATCH] clk: meson: add regmap helpers for parm Meson clock drivers are using struct parm to describe each field of the clock provider. Providing helpers to access these fields with regmap helps to keep drivers readable Signed-off-by: Jerome Brunet Signed-off-by: Neil Armstrong --- drivers/clk/meson/clkc.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/drivers/clk/meson/clkc.h b/drivers/clk/meson/clkc.h index aa2dfa0ff89f..8edc25297422 100644 --- a/drivers/clk/meson/clkc.h +++ b/drivers/clk/meson/clkc.h @@ -38,6 +38,22 @@ struct parm { u8 width; }; +static inline unsigned int meson_parm_read(struct regmap *map, struct parm *p) +{ + unsigned int val; + + regmap_read(map, p->reg_off, &val); + return PARM_GET(p->width, p->shift, val); +} + +static inline void meson_parm_write(struct regmap *map, struct parm *p, + unsigned int val) +{ + regmap_update_bits(map, p->reg_off, SETPMASK(p->width, p->shift), + val << p->shift); +} + + struct pll_rate_table { unsigned long rate; u16 m;
