As per bpsec, CHICKEN_TRANS_EDP bit 12 ,15 must be programmed in
psr2 enable sequence.
bit 12 : Program Transcoder EDP VSC DIP header with a valid setting for
PSR2 and Set CHICKEN_TRANS_EDP(0x420cc) bit 12 for programmable
header packet.
bit 15 : Set CHICKEN_TRANS_EDP(0x420cc) bit 15 if Y coordinate is supported
v2: (Rodrigo)
- move CHICKEN_TRANS_EDP bit set logic right after setup_vsc
v3:(Rodrigo)
- initialize chicken_trans to CHICKEN_TRANS_BIT12 instead of 0
v4:(chris wilson)
- use BIT(12), remove CHICKEN_TRANS_BIT12
- remove unnecessary comments
- update commit message
v5:
- rename bit 12 PSR2_VSC_ENABLE_PROG_HEADER
- rename bit 15 PSR2_ADD_VERTICAL_LINE_COUNT
v6:(Rodrigo)
- remove TRANS_EDP=3, use cpu_transcoder

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
