[PATCH v4 0/2] OMAPDSS: HDMI: Boardfile cleanup

From: Mythri P K <mythripk <at> ti.com>

Clean up of boardfiles to have the functions common to differnt boards in a
common display file, Also in some OMAP4 boards external pull-up's are enabled
thus enabling internal pull up should be a parameter from the boardfile.

changes since v3 : Comment improvement to move some portion from boardfile to
display.
changes since v2 : Make the flag as enum.
changes since v1 : Make omap hdmi_init generic to handle different parameters
and pass the pull up as a flag instead of int. 

Mythri P K (2):
  OMAPDSS: HDMI: Move duplicate code from boardfile
  OMAPDSS: HDMI: Disable DDC internal pull up

[PATCH v4 2/2] OMAPDSS: HDMI: Disable DDC internal pull up

From: Mythri P K <mythripk <at> ti.com>

Disables the internal pull resistor for SDA and SCL which are enabled by
default, as there are external pull up's in 4460 and 4430 ES2.3
SDP, Blaze and Panda Boards, It is done to avoid the EDID read failure.

[PATCH 0/4] OMAPDSS: HDMI: Improve the timings logic in HDMI

From: Mythri P K <mythripk <at> ti.com>

There are some duplicate timing structure which are not needed thus removing
them to clean the code.
Also the static mapped timing structure is quite complicated to add new
timings, so simplify it by using array indexed method.

changes since V1: change of hdmi_find_timing function to return pointer to the
timing struct rather than deep copy to timing structure passed as parameter
variable name change from temp to timing2 in comparator function.

Mythri P K (4):
  OMAPDSS: HDMI: remove duplicate video interface code
  OMAPDSS: HDMI: update static timing table
  OMAPDSS: HDMI: change the timing match logic
  OMAPDSS: HDMI: remove duplicate code and mode parameter

[PATCH v2 1/4] OMAPDSS: HDMI: remove duplicate video interface code

From: Mythri P K <mythripk <at> ti.com>

video interface structure is a duplicate structure with parameters which are
already present in ip_data config structure, Thus removing the structure and
modifying corresponding code.

[PATCH v2 3/4] OMAPDSS: HDMI: change the timing match logic

From: Mythri P K <mythripk <at> ti.com>

Change the timing match logic, Instead of the statically mapped method
to get the corresponding timings for a given code and mode, move to a
simpler array indexed method. It  will help to scale up to add more
timings when needed.
