Hi Tomi, l-o list,
The main purpose of this patch set is to create a platform device for audio
support from the OMAPDSS HDMI driver. This tries to follow an approach similar
to MFD drivers in which a core driver creates domain-specific devices. Under
this approach, the OMAPDSS HDMI drivers acts as the core driver, retrieves its
resources (from DT or hwmod) and passes the relevant audio resources for
other drivers to use.
This is also beneficial for future DT boot support, as the OMAP HDMI IP will be
represented by a single node in the tree.
Before creating the platform device for audio, I also did minor cleanup to the
OMAPDSS HDMI driver probe function.
Changes from v2:
*Check the validity of the audio platform device by checking a non-NULL
condition
rather than an error pointer condition.
*Pass the ID of the HDMI platform device to handle more than one instance of
HDMI audio platform devices. This is for future implementations that support
more than one HDMI output.
Changes from v1:
*Simplify ioremap further by using devm_request_and_ioremap.
*Pass to the audio driver only the DMA port and not the whole register space.
*Use a local array for the audio resources and init them with DEFINE_RES_MEM.
*Obtain the DMA port address offset and size from the HDMI IP-specific library.
