[PATCH 1/5] ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02

[Dmitry Lavnikevich]

Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.

[PATCH 5/5] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

[PATCH 5/5] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

Is it possible to use the simple-card
(Documentation/devicetree/bindings/sound/simple-card.txt) instead of
adding a new audio card driver? There are also DT bindings for the imx
audiomultiplexer (imx-audmux.txt).

Best regards,

Markus

Is it possible to use the simple-card
(Documentation/devicetree/bindings/sound/simple-card.txt) instead of
adding a new audio card driver? There are also DT bindings for the imx
audiomultiplexer (imx-audmux.txt).

Best regards,

Markus

This whole single patch looks pretty clean. So I suggest it may be merged
into fsl-asoc-card.c driver whose DT binding is almost identical to yours
so that we don't need to add a machine driver with duplicated code. And
you can feel free to enable fsl-asoc-card in the defconfig as well -- I
was about to do it and to replace imx-wm8962 and imx-sgtl5000 with it.

The only extra trivia you need to tackle is to add a clock binding into
your dts for CODEC side.

Thanks

I don't know why my mutt doesn't display this mail.

Anyway, if Simple Card supports audmux, yes, it's also a good idea.

Simple Card doesn't support it. But there are DT bindings for the audmux
device node which allow the definition of a default multiplexer setup.
That configuration is applied in the probe() function of the audmux driver.

I have seen boards use the GPIO_3/6 pads instead of EIM_D17/D18 for
I2C3, but the EIM_D17/D18 are indeed documented as "I2C1" pins at the
pfla02 connector level.

I have seen boards use the GPIO_3/6 pads instead of EIM_D17/D18 for
I2C3, but the EIM_D17/D18 are indeed documented as "I2C1" pins at the
pfla02 connector level.

Yes, I've checked - it can be implemented with simple card +
audmux configuration. Thanks for great suggestion. It will be
done in next patchset version.

Yes, that is why I thought about moving it into pfla02. But apart from
it, i2c2grp i2c3grp nodes was wrongly placed under iomuxc node while
it should be grouped inside of it, like in imx6q-phytec-pfla02 to
which it was moved with this patch.
Because of this specified i2c wasn't working correctly and caused
messages:

This patch fixes i2c2, i2c3 pin configuration which caused messages:

[PATCH v2 4/4] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

[PATCH v3 0/4] Add Phytec pbab01 audio support

[Dmitry Lavnikevich]

New phyFLEX board audio patchset version.

Defines from dt-bindings/sound/fsl-imx-audmux.h are now used in audmux
configuration instead of hardcoded register values.

Also patchset is now based on branch for-next from
git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git which
means:

- removed #sound-dai-cells in ssi2 node since it was already moved to
  imx6qdl.dtsi;
- patch for imx_v6_v7_defconfig now enables only
  CONFIG_SND_SOC_TLV320AIC3X since CONFIG_SND_SIMPLE_CARD also was
  already enabled.

[PATCH v3 1/4] ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02

[Dmitry Lavnikevich]

Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.

This patch fixes i2c2, i2c3 pin configuration which caused messages:

[PATCH v3 1/4] ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02

[Dmitry Lavnikevich]

Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.

This patch fixes i2c2, i2c3 pin configuration which caused messages:

[PATCH v3 4/4] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

[PATCH v3 4/4] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

@0 and @1 are used for "usb_otg_vbus" and "usb_h1_vbus" regulators in 
dts for phyFLEX module (imx6qdl-phytec-pfla02.dtsi) which gets included 
before base board dts (imx6qdl-phytec-pbab01.dtsi)

why is there no need for 'regulator-alweys-on'? I see it in
similar fixed regulator descriptions in imx6qdl-sabrelite.dtsi,
imx6qdl-wandboard.dtsi, imx6qdl-nitrogen6x.dtsi and many other

yes, thanks. It is present in Documentation but now I see that it

For a regulator that is not GPIO controlled you don't need to pass
'regulator-always-on'.

For a regulator that is not GPIO controlled you don't need to pass
'regulator-always-on'.

Ok, I will remove it also.

I will wait some time for other notes on patches and resend patchset.

[PATCH v4 0/4] Add Phytec pbab01 audio support

[Dmitry Lavnikevich]

New phyFLEX board audio patchset version.

Small changes made since last version:

- removed unnecessary 'regulator-always-on' in fixed regulators dts
  description;
- removed 'fsl,mode = "i2s-slave"' from ssi2 node in dts since it was
  already removed from fsl-ssi driver.

Based on branch for-next from
git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git

[PATCH v4 1/4] ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02

[Dmitry Lavnikevich]

Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.

This patch fixes i2c2, i2c3 pin configuration which caused messages:

[PATCH v4 4/4] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

[PATCH v4 4/4] ASoC: tlv320aic3x: fix PLL D configuration

[Dmitry Lavnikevich]

Current caching implementation during regcache_sync() call bypasses
all register writes of values that are already known as default
(regmap reg_defaults). Same time in TLV320AIC3x codecs register 5
(AIC3X_PLL_PROGC_REG) write should be immediately followed by register
6 write (AIC3X_PLL_PROGD_REG) even if it was not changed. Otherwise
both registers will not be written.

This brings to issue that appears particulary in case of 44.1kHz
playback with 19.2MHz master clock. In this case AIC3X_PLL_PROGC_REG
is 0x6e while AIC3X_PLL_PROGD_REG is 0x0 (same as register
default). Thus AIC3X_PLL_PROGC_REG also remains not written and we get
wrong playback speed.

In this patch snd_soc_read() is used to get cached pll values and
snd_soc_write() (unlike regcache_sync() this function doesn't bypasses
hardware default values) to write them to registers.

Applied, thanks.  This should really have been sent separately to the
other patches - it's not in any way specific to the board and there's no
dependency in either direction.
