Subject: [PATCH v3 0/6] HDMI 2.0: Scrambling in DRM layer
Date: Fri, 10 Feb 2017 21:59:22 +0530 [thread overview]
Message-ID: <1486744168-7857-1-git-send-email-shashank.sharma@intel.com> (raw)
HDMI 2.0 spec defines a method to reduce the RF footprint while
operating at higher pixel clocks, which is called Scrambling.
Scrambling can be controlled over a new set of I2C registers
which are accessible over existing DDC I2C lines, called SCDC
register set.
This patch series contains 6 patches:
- First two patches add generic drm helper functions to read and
write into SCDC registers. These patches are written by Thierry,
in a patch series published here:
https://patchwork.kernel.org/patch/9459051/
Minor changes were done to map the patches into this series.
- Next two patches add functions for scrambling detection and
scrambling control.
- Next two patches use this infrastructure in DRM layer from
I915 driver, to enable scrambling on a GLK deivce which sports
a native HDMI 2.0 controller.
V2:
- addressed review comments from Thierry, Ville and Dhinakaran
- added signed-off-by:self in first two patches(Jani N)
V3:
- addressed review comments from Jose and Jani
Shashank Sharma (4):
drm/edid: detect SCDC support in HF-VSDB
drm: scrambling support in drm layer
drm/i915: enable scrambling
drm/i915: allow HDMI 2.0 clock rates
Thierry Reding (2):
drm: Add SCDC helpers
drm/edid: check for HF-VSDB block
