Function intel_pixel_encoding_setup_vsc handles vsc header and data block setup for pixel encoding / colorimetry format. Setup VSC header and data block in function intel_pixel_encoding_setup_vsc for pixel encoding / colorimetry format as per dp 1.4a spec, section 2.2.5.7.1, table 2-119: VSC SDP Header Bytes, section 2.2.5.7.5, table 2-120:VSC SDP Payload for DB16 through DB18. v2: Minor style fix. [Maarten] Refer to commit ids instead of patchwork. [Maarten] v6: Rebase v7: Rebase and addressed review comments from Ville. Use a structure initializer instead of memset(). Fix non-standard comment format. Remove a referring to specific commit. Add a setting of dynamic range bit to vsc_sdp.DB17. Add a setting of bpc which is based on pipe_bpp. Remove duplicated checking of connector's ycbcr_420_allowed from intel_pixel_encoding_setup_vsc(). It is already checked from intel_dp_ycbcr420_config(). Remove comments for VSC_SDP_EXTENSION_FOR_COLORIMETRY_SUPPORTED. It is already implemented on intel_dp_get_colorimetry_status(). v8: A missing of setting bpc to VSC setup is the pretty fatal case, it replaces DRM_DEBUG_KMS() to MISSING_CASE(). [Maarten] v9: Use a changed member name of struct dp_sdp. it renamed to db from DB.

* from HDCP over DP, so to account for these differences, we need to
|

* communicate with the receiver through this shim.
|
|
*
|
|
* For completeness, the 2 buses differ in the following ways:
|
|
* - DP AUX vs. DDC
|
|
* HDCP registers on the receiver are set via DP AUX for DP, and
|
|
* they are set via DDC for HDMI.
|
|
* - Receiver register offsets
|
|
* The offsets of the registers are different for DP vs. HDMI
|
|
* - Receiver register masks/offsets
|
|
* For instance, the ready bit for the KSV fifo is in a different
|
|
* place on DP vs HDMI
|
|
* - Receiver register names
|
|
* Seriously. In the DP spec, the 16-bit register containing
|
|
* downstream information is called BINFO, on HDMI it's called
|
|
* BSTATUS. To confuse matters further, DP has a BSTATUS register
|
|
* with a completely different definition.
|
|
* - KSV FIFO
|
|
* On HDMI, the ksv fifo is read all at once, whereas on DP it must
|
|
* be read 3 keys at a time
|
|
* - Aksv output
|
|
* Since Aksv is hidden in hardware, there's different procedures
|
|
* to send it over DP AUX vs DDC
