HDMI IP block is common between TI OMAP4 Procerssor and Netra processor although
the Display subsytem is different.Also the IP block in future OMAP may differ
from the one existing in OMAP4. Thus to reuse the code between these two
processors , and maintain the multi omap build functionality in DSS.
HDMI IP dependant code is seperated out from hdmi.c and moved to
new library file hdmi_ti_4xxx_ip.c.From the DSS dependent HDMI code only the
function pointer to functionality/features offered by HDMI is called.
This patch series does the split and also renames hdmi_omap4_panel.c to
hdmi_panel.c as that file has nothing specific to OMAP4 and can be reused for
other OMAP family of processors as well.
This patch series is based on Tomi's LO-DSS2 master branch.
changes since V1: Function pointer approach to call the HDMI IP functions from
DSS HDMI
Mythri P K (10):
OMAP4: DSS: HDMI: HDMI clean up to pass base_address dynamically
to IP dependant functions of HDMI
OMAP4: DSS: HDMI: Move pll and video configuration info to ip_data
structure
OMAP4: DSS: HDMI: Use specific HDMI timings structure instead of OMAP
DSS timings
OMAP4: DSS: HDMI: Move the common header file definition to
Include/video
OMAP4 : DSS : HDMI : Move the EDID portion from HDMI IP header
OMAP4: DSS2: HDMI: Split the HDMI driver to DSS and IP
specific portion.
OMAP4: DSS2: HDMI: Provide a wrapper API to configure PLL and
PHY configuration
OMAP4: DSS2: HDMI: Function pointer approach to call HDMI IP
driver function from DSS
MAP4: DSS: HDMI: Rename the functions in HDMI IP library to IP
specific name
OMAP4: DSS: Rename hdmi_omap4_panel.c to hdmi_panel.c

As the base_address of the HDMI might differ across SoC's, offset of the HDMI
logical blocks and base address got from the platform data are passed
dynamically to the functions that modify HDMI IP registers.

As the pll and the video configuration info are part of the ip_data those
structures are moved to the ip_data strtucure.Also the functions are modified
accordingly to take care of this movement.

Some of the header file definitions of HDMI IP are needed by audio driver thus
moving the common defintion to more generic Include/video.

To make the current hdmi DSS driver compatible with future OMAP with different
IP blocks , add HDMI as a feature in dss_features and abstract the internal
function in hdmi dss driver.

Functions that are included in the generic video include of HDMI TI OMAP4, TI8xx
etc IP library is renamed to have IP specific names so that it will not conflict
with similar function from other IP.

structure and definition typoed. And the point is not to remove hdmi
stuff from dss, but dss stuff from hdmi. The generic hdmi driver cannot
use omap dss specific stuff.

I don't think I quite understood why refsel is not part of the pll info.
And if it has to be hardcoded, you could as well do that in
hdmi_pll_init().

This commit message doesn't make much sense. What you do in this patch
is just rename the functions, and add the hdmi_pll_disable function.

No space before comma.
The description could use some improvement, HDMI is not "a feature in
dss_features", and I don't understand what the rest of the sentence
means.

As the functions will be renamed to hdmi_ti_4xxx_*, perhaps the header
file is a bit misnamed.
Also, please first do the changes/renamings/etc, and only then move the
finished header file to include/video/ to prevent unnecessary changes in
include/video.

So, why refsel is not part of the pll info? The HW doesn't support
changing it? If so, is it only for OMAPs or for all SoCs?

The Include/video hdmi header file is a generic file that can be used
across 4 ,5 and Netra. Actually even the hdmi_ti_5xxx_ definitions
would come in this header so what do you think it can be named as ? ,
If you have any better name for hdmi_ti_4xxx_ip as well please suggest
would be happy to take it , as it doesn't sound that intuitive to me
as well.

It is a variable parameter ,H/w supports changing it but it is never tried,
I was considering hard-coding it in the hdmi.c and passing it,
so that there would be no hard-coding in IP functions.

Well, I think whatever the header name is, it should somehow match the
functions and the .c file. So if the functions and the .c file in this
case are hdmi_ti_4xxx, then it'd be logical for the .h file to be named
similarly.
So, if it will contain functions for other IPs also, perhaps just leave
the 4xxx out of it and name it hdmi_ti.h. Then the functions could be
named hdmi_ti_4xxx_yyy(), and accordingly the .c file can be
hdmi_ti_4xxx.c.
Or, perhaps ti_hdmi.h (and funcs & .c files accordingly) would be more
"standard", as it's quite usual to name drivers etc. starting with the
company name.
