Ricardo Neri 80a4859628 OMAPDSS: HDMI: Create function to enable HDMI audio
In order to separate clearly IP-specific code from general DSS code,
a function for OMAP4 audio enable is created. This function is
included in the HDMI IP ops to align with the current implementation
of the DSS HDMI driver. This function is to be used by the ASoC
HDMI audio codec.

Tomi Valkeinen 759593ffa7 OMAP: DSS2: HDMI: implement detect()
Implement detect() by checking the hot plug detect status.

The implementation is not very good, as it always turns on the HDMI
output to get the detection working. HDMI driver needs improvements so
that we could enable only core parts of it.

Tomi Valkeinen 937fce138f OMAP: DSS2: HDMI: clean up edid reading & fix checksum
Clean up reading of EDID by passing direct address to the block being
read, instead of start address of the whole EDID memory area. Rewrite
the loop which reads the EDID.

This also fixes the checksum calculation, which used to calculate the
checksum only for the first block.

Mythri P K 60634a28bc OMAP4: DSS2: HDMI: Function pointer approach to call
HDMI IP fundamentally has replaceable core PHY and PLL blocks.
These blocks might vary across OMAP's but the end functionality such as to
enable or disable PLL, PHY, function to read EDID would remain the same.

Thus to make the current hdmi DSS driver compatible with different OMAP's having
different IP blocks( A combination of different core, PHY, PLL blocks), function
pointer approach is introduced.

With function pointer, relevant IP dependent functions are mapped to the generic
functions used by DSS during the initialization based on the OMAP compiled.
Thus making hdmi DSS driver IP agnostic.

Mythri P K 176b578b1a OMAP4: DSS2: HDMI: Rename the functions in HDMI IP library
Functions that are included in HDMI IP driver is renamed to have
IP specific names so that it will not conflict with similar functions
from other IP.

Mythri P K 7d983f39ec OMAP4: DSS2: HDMI: Split the current HDMI driver to move
Split the current HDMI driver to move the HDMI IP dependent ( PLL/PHY/Core
configuration code) to a new IP file (ti_hdmi_4xxx_ip.c.
This is to separate IP dependent OMAP agnostic code from OMAP specific DSS
dependent code.

Mythri P K 94c52987d2 OMAP4: DSS2: HDMI: Move HDMI IP independent generic header
Some of the header file definitions that are there in the hdmi.h are generic
and can be used across OMAP's, Thus moving generic definition to new file.
