[PATCH 0/3] ARM: OMAP: Add platform devices for ASoC HDMI drivers

[Ricardo Neri]

This set of patches is intended to add the platform devices for the ASoC
HDMI drivers when not using device tree. For this, I took an approach similar
to DMIC and McPDM by creating a dedicated functions to create the devices.

I included the device for the CPU DAI driver, omap-hdmi-audio-dai, and the
device for the machine driver, omap-hdmi-audio, in devices.c to reflect the
fact that any OMAP4 (and OMAP5 in the future) has HDMI IP. I put the device
for the codec in the board file to reflect the fact that not necessarily all
the boards with OMAP4/5 have the HDMI output wired.

Best regards

Ricardo

[PATCH 1/3] ARM: OMAP: devices: Register platform devices for HDMI audio

[Ricardo Neri]

Add platform registration for the devices HDMI audio support. The
omap-hdmi-audio-dai platform device is to be used by the ASoC HDMI
CPU DAI driver. The omap-hdmi-audio platform device is to be used
by the ASoC HDMI machine driver that links together the ASOC CPU DAI,
ASoC plaform and ASoC codec drivers.

[PATCH 2/3] ARM: OMAP4: board-4430sdp: Register platform device for HDMI audio codec

[Ricardo Neri]

Add platform device registratation for HDMI audio codec. This is to
be able to transmit audio through the HDMI output featured in SDP4430
and Blaze boards.

Hi Tony,

I was wondering if you've had the time to take a look at these patches.

Thanks!

Hi Tony,

This is me again; asking if you had any chance to look at these patches.

Thanks!
