This should allow us to do some more complex -clock management and power control. Also, some of the -on-board chip clocks can be exposed to the outside, and this -change will make those clocks easier to consume by other -parts of the kernel. - -Signed-off-by: Annaliese McDermond <nh6z@nh6z.net> -Signed-off-by: Mark Brown <broonie@kernel.org> ---- - sound/soc/codecs/tlv320aic32x4-clk.c | 34 ++++++++++++++++++++++++++++ - sound/soc/codecs/tlv320aic32x4.c | 18 +++++++++++---- - 2 files changed, 47 insertions(+), 5 deletions(-) - ---- a/sound/soc/codecs/tlv320aic32x4-clk.c -+++ b/sound/soc/codecs/tlv320aic32x4-clk.c -@@ -265,6 +265,30 @@ static const struct clk_ops aic32x4_pll_ - .get_parent = clk_aic32x4_pll_get_parent, - }; - -+static int clk_aic32x4_codec_clkin_set_parent(struct clk_hw *hw, u8 index) -+{ -+ struct clk_aic32x4 *mux = to_clk_aic32x4(hw); -+ -+ return regmap_update_bits(mux->regmap, -+ AIC32X4_CLKMUX, -+ AIC32X4_CODEC_CLKIN_MASK, index << AIC32X4_CODEC_CLKIN_SHIFT); -+} -+ -+static u8 clk_aic32x4_codec_clkin_get_parent(struct clk_hw *hw) -+{ -+ struct clk_aic32x4 *mux = to_clk_aic32x4(hw); -+ unsigned int val; -+ -+ regmap_read(mux->regmap, AIC32X4_CLKMUX, &val); -+ -+ return (val & AIC32X4_CODEC_CLKIN_MASK) >> AIC32X4_CODEC_CLKIN_SHIFT; -+} -+ -+static const struct clk_ops aic32x4_codec_clkin_ops = { -+ .set_parent = clk_aic32x4_codec_clkin_set_parent, -+ .get_parent = clk_aic32x4_codec_clkin_get_parent, -+}; -+ - static struct aic32x4_clkdesc aic32x4_clkdesc_array[] = { - { - .name = "pll", -@@ -274,6 +298,14 @@ static struct aic32x4_clkdesc aic32x4_cl - .ops = &aic32x4_pll_ops, - .reg = 0, - }, -+ { -+ .name = "codec_clkin", -+ .parent_names = -+ (const char *[]) { "mclk", "bclk", "gpio", "pll" }, -+ .num_parents = 4, -+ .ops = &aic32x4_codec_clkin_ops, -+ .reg = 0, -+ }, - }; - - static struct clk *aic32x4_register_clk(struct device *dev, -@@ -314,6 +346,8 @@ int aic32x4_register_clocks(struct devic - */ - aic32x4_clkdesc_array[0].parent_names = - (const char* []) { mclk_name, "bclk", "gpio", "din" }; -+ aic32x4_clkdesc_array[1].parent_names = -+ (const char *[]) { mclk_name, "bclk", "gpio", "pll" }; - - for (i = 0; i < ARRAY_SIZE(aic32x4_clkdesc_array); ++i) - aic32x4_register_clk(dev, &aic32x4_clkdesc_array[i]); ---- a/sound/soc/codecs/tlv320aic32x4.c -+++ b/sound/soc/codecs/tlv320aic32x4.c -@@ -737,12 +737,9 @@ static int aic32x4_setup_clocks(struct s - - aic32x4_set_processing_blocks(component, aic32x4_divs[i].r_block, aic32x4_divs[i].p_block); - -- /* PLL as CODEC_CLKIN */ -- snd_soc_component_update_bits(component, AIC32X4_CLKMUX, -- AIC32X4_CODEC_CLKIN_MASK, -- AIC32X4_CODEC_CLKIN_PLL << AIC32X4_CODEC_CLKIN_SHIFT); - /* DAC_MOD_CLK as BDIV_CLKIN */ -- snd_soc_component_update_bits(component, AIC32X4_IFACE3, AIC32X4_BDIVCLK_MASK, -+ snd_soc_component_update_bits(component, AIC32X4_IFACE3, -+ AIC32X4_BDIVCLK_MASK, - AIC32X4_DACMOD2BCLK << AIC32X4_BDIVCLK_SHIFT); - - /* NDAC divider value */ -@@ -989,6 +986,15 @@ static int aic32x4_component_probe(struc - { - struct aic32x4_priv *aic32x4 = snd_soc_component_get_drvdata(component); - u32 tmp_reg; -+ int ret; -+ -+ struct clk_bulk_data clocks[] = { -+ { .id = "codec_clkin" }, -+ }; -+ -+ ret = devm_clk_bulk_get(component->dev, ARRAY_SIZE(clocks), clocks); -+ if (ret) -+ return ret; - - if (gpio_is_valid(aic32x4->rstn_gpio)) { - ndelay(10); -@@ -1000,6 +1006,8 @@ static int aic32x4_component_probe(struc - if (aic32x4->setup) - aic32x4_setup_gpios(component); - -+ clk_set_parent(clocks[0].clk, clocks[1].clk); -+ - /* Power platform configuration */ - if (aic32x4->power_cfg & AIC32X4_PWR_MICBIAS_2075_LDOIN) { - snd_soc_component_write(component, AIC32X4_MICBIAS, |
