A good rule of thumb is that when you have "also" in your commit log, you should do another patch instead doing that instead. > > Signed-off-by: Danny Milosavljevic <dannym@scratchpost.org> > --- > sound/soc/sunxi/sun4i-codec.c | 66 ++++++++++++++++++++++++++++++++++++------- > 1 file changed, 56 insertions(+), 10 deletions(-) > > diff --git a/sound/soc/sunxi/sun4i-codec.c b/sound/soc/sunxi/sun4i-codec.c > index 060a40b45ab0..4af286f44a67 100644 > --- a/sound/soc/sunxi/sun4i-codec.c > +++ b/sound/soc/sunxi/sun4i-codec.c > @@ -95,6 +95,8 @@ > #define SUN4I_CODEC_ADC_ACTL_PREG1EN (29) > #define SUN4I_CODEC_ADC_ACTL_PREG2EN (28) > #define SUN4I_CODEC_ADC_ACTL_VMICEN (27) > +#define SUN4I_CODEC_ADC_ACTL_PREG1 (25) > +#define SUN4I_CODEC_ADC_ACTL_PREG2 (23) > #define SUN4I_CODEC_ADC_ACTL_VADCG (20) > #define SUN4I_CODEC_ADC_ACTL_ADCIS (17) > #define SUN4I_CODEC_ADC_ACTL_PA_EN (4) > @@ -111,6 +113,9 @@ > /* Microphone controls (sun7i only) */ > #define SUN7I_CODEC_AC_MIC_PHONE_CAL (0x3c) > > +#define SUN7I_CODEC_AC_MIC_PHONE_CAL_PREG1 (29) > +#define SUN7I_CODEC_AC_MIC_PHONE_CAL_PREG2 (26) > + > /* > * sun6i specific registers > * > @@ -676,6 +681,12 @@ static const struct snd_kcontrol_new sun4i_codec_pa_mute = > static DECLARE_TLV_DB_SCALE(sun4i_codec_pa_volume_scale, -6300, 100, 1); > static DECLARE_TLV_DB_SCALE(sun4i_codec_micin_loopback_gain_scale, -450, 150, > 0); > +static DECLARE_TLV_DB_RANGE(sun4i_codec_micin_preamp_gain_scale, > + 0, 0, TLV_DB_SCALE_ITEM(0, 0, 0), > + 1, 7, TLV_DB_SCALE_ITEM(3500, 300, 0)); > +static DECLARE_TLV_DB_RANGE(sun7i_codec_micin_preamp_gain_scale, > + 0, 0, TLV_DB_SCALE_ITEM(0, 0, 0), > + 1, 7, TLV_DB_SCALE_ITEM(2400, 300, 0)); > > static const struct snd_kcontrol_new sun4i_codec_controls[] = { > SOC_SINGLE_TLV("Power Amplifier Volume", SUN4I_CODEC_DAC_ACTL, > @@ -686,6 +697,24 @@ static const struct snd_kcontrol_new sun4i_codec_controls[] = { > sun4i_codec_micin_loopback_gain_scale), > }; > > +static const struct snd_kcontrol_new sun4i_codec_extra_controls[] = { > + SOC_SINGLE_TLV("Mic1 Boost Volume", SUN4I_CODEC_ADC_ACTL, > + SUN4I_CODEC_ADC_ACTL_PREG1, 3, 0, > + sun4i_codec_micin_preamp_gain_scale), > + SOC_SINGLE_TLV("Mic2 Boost Volume", SUN4I_CODEC_ADC_ACTL, > + SUN4I_CODEC_ADC_ACTL_PREG2, 3, 0, > + sun4i_codec_micin_preamp_gain_scale), > +}; > + > +static const struct snd_kcontrol_new sun7i_codec_extra_controls[] = { > + SOC_SINGLE_TLV("Mic1 Boost Volume", SUN7I_CODEC_AC_MIC_PHONE_CAL, > + SUN7I_CODEC_AC_MIC_PHONE_CAL_PREG1, 7, 0, > + sun7i_codec_micin_preamp_gain_scale), > + SOC_SINGLE_TLV("Mic2 Boost Volume", SUN7I_CODEC_AC_MIC_PHONE_CAL, > + SUN7I_CODEC_AC_MIC_PHONE_CAL_PREG2, 7, 0, > + sun7i_codec_micin_preamp_gain_scale), > +}; > + > static const struct snd_kcontrol_new sun4i_codec_left_mixer_controls[] = { > SOC_DAPM_SINGLE("Left DAC Playback Switch", SUN4I_CODEC_DAC_ACTL, > SUN4I_CODEC_DAC_ACTL_LDACLMIXS, 1, 0), > @@ -807,7 +836,30 @@ static const struct snd_soc_dapm_route sun4i_codec_codec_dapm_routes[] = { > { "Mic2", NULL, "VMIC" }, > }; > > +struct sun4i_codec_quirks { > + const struct regmap_config *regmap_config; > + const struct snd_soc_component_driver *codec; > + struct snd_soc_card * (*create_card)(struct device *dev); > + struct reg_field reg_adc_fifoc; /* used for regmap_field */ > + unsigned int reg_dac_txdata; /* TX FIFO offset for DMA config */ > + unsigned int reg_adc_rxdata; /* RX FIFO offset for DMA config */ > + bool has_reset; > + const struct snd_kcontrol_new *controls; > + unsigned int num_controls; > +}; > + > +static int sun4i_codec_component_driver_probe(struct snd_soc_component *codec) > +{ > + const struct sun4i_codec_quirks *quirks; > + > + quirks = of_device_get_match_data(codec->dev); > + return snd_soc_add_component_controls(codec, > + quirks->controls, > + quirks->num_controls); Why not just extending the sun4i_codec_controls to add it, and create a duplicate one for the A20?

Because sun4i_codec_controls has five controls shared between A10 and A20, and only two not shared. And if we extended sun4i_codec_controls, we'd also have to duplicate sun4i_codec_codec in order to use sun4i_codec_controls vs. sun7i_codec_controls, which really contains exactly the same data otherwise. The quirks here are just for two controls, Mic1 Boost Volume and Mic2 Boost Volume, and there not even for the names or anything - just for some reason the register moved away. The simplest way was to add it to the quirks - which already have a variant selection etc.

What I don't really like is that with this patch we have two variants of the same mechanism: one to add the controls that are mostly shared, and one to add the controls that are not shared, without any clear definition of when you should add a new control to one list or the other. So far, we had one mechanism, it was easy to understand and to know what to do about it. And the code was simple as well. > The quirks here are just for two controls, Mic1 Boost Volume and > Mic2 Boost Volume, and there not even for the names or anything - > just for some reason the register moved away. > > The simplest way was to add it to the quirks - which already have a > variant selection etc. Actually, I think that having to do add a new control explicitly to an A10 and an A20 list is a feature if the two controls set aren't exactly the same. It makes you explicitly think about what you're doing, and hopefully double check if it is actually shared or not, instead of exposing a control because one didn't pay attention that it was shared. Chen-Yu, any opinion on this? Maxime
