[PATCH v2 0/2] ARM: dts: exynos: Updates for Odroid HDMI audio

[Sylwester Nawrocki]

These patches are intended for v4.16-rc1 as they depend on the HDMI
codec patch which is going to be merged in coming merge window.

[PATCH v2 1/2] ARM: dts: exynos: Switch to dedicated Odroid-XU3 sound card binding

[Sylwester Nawrocki]

The new sound card DT binding is used for Odroid XU3 in order
to properly support the HDMI audio path.
Clocks configuration is changed so the I2S controller is now the bit
and the frame clock master with EPLL as the root clock source.

Patch looks good but I do not understand this last sentence. What did
you want to say?

Which part is hard to understand exactly? Perhaps this is clearer?

"Clocks configuration is changed so the I2S controller is now the bit
clock and the frame clock master.  The EPLL output clock is now the 
audio root clock adjusted to each audio sample rate."

Previously the CODEC's internal PLL was used for generating the I2S
bit and frame clocks accorrding to each audio sample rate.

Ahhh, makes sense, the previous "is not the bit and..." mislead me. I
thought it's a typo, you wanted to use "but" and something is missing.
The extended description is I think better, so I'll use it in commit
msg when applying.

Best regards,
Krzysztof

Unfortunately this patch causes the audio card to disappear on Odroid
XU3. "aplay -L" shows nothing and obviously speaker-test fails.

Applied on v4.15-rc1... any dependencies are missing?

Full boot-logs are here:
http://www.krzk.eu/#/builders/1/builds/976
(test exits on aplay -L).

Should this be dropped?

Best regards,
Krzysztof

Please add CONFIG_SND_SOC_ODROID=y to you .config. Probably exynos_defconfig
and multi_v7_defconfig should be updated too.

That would explain it. Can you send a patch for both of configs?

[PATCH v2 2/2] ARM: dts: exynos: Add sound support for Odroid XU4

[Sylwester Nawrocki]

This patch adds support for Odroid XU4 audio. The main difference
comparing to Odroid XU3 is a missing on-board audio CODEC, only
HDMI output is supported on Odroid XU4. External CODEC could be
optionally connected to the I2S port connector.
