Subject: [PATCH v5 00/12] drm/sun4i: Add A83t LVDS support
Date: Thu, 21 Dec 2017 12:02:26 +0100 [thread overview]
Message-ID: <cover.e5a47cc96ec5274dd932daa2bde47df073087da9.1513854122.git-series.maxime.ripard@free-electrons.com> (raw)
Hi,
Here is an attempt at supporting the LVDS output in our DRM driver. This
has been tested on the A83T (with DE2), but since everything is basically
in the TCON, it should also be usable on the older SoCs with minor
modifications.
This was the occasion to refactor a bunch of things. The most notable ones
would be the documentation, and split of the UI layers in the mixer code,
and the switch to kfifo for our endpoint parsing code in the driver that
fixes an issue introduced by the switch to BFS.
Let me know what you think,
Maxime
Changes from v4:
- Changed the order of the clk_prepare_enable and clk_set_rate for the
mixer module clock
- Squash the two DT PWM patches
- Removed the output pins muxing
- Changed the flag to tell if you have an LVDS alternate clock to
has_lvds_alt
- Used SPDX headers
Changes from v3:
- Collect the tags
- Use SPDX headers when possible
- Added the new mixer configuration options
- Changed the LVDS clock for lvds-alt instead of lvds-pll
- Removed the MIPI PLL from the A31s
- Changed the LVDS_ANA0 macros name to reflect the generation they were
introduced in, and added a comment to mention the changes needed to
support the older SoCs
Changes from v2:
- Move the module clock rate to the mixer structure
- Adjusted the simple-panel documentation for power-supply
- Changed the compatible for the first A83t mixer to mixer 0
- Rebased on top of current drm-misc
- Split out the A83t bindings in its separate patch
Changes from v1:
- Added a fix for the error path handling in the TCON
- Enable the TCON by default
- Removed the patch that changes the channels offset but kept most of the
modifications as a cleanup
- Deal with the LVDS clock being able to have another PLL parent on some
SoCs
- Renamed the TCON compatible to TCON-TV, following the convention used
on newer SoCs
- Removed the hardcoded timings
- Moved LVDS enable quirks to a separate function
- Used clock indices define in the DT
- Removed the hardcoded clock rate in the DT and moved it to the driver
- Changed sun8i_mixer_planes to sun8i_mixer_ui_planes to be consistent
- Added the various tags collected
- Rebased on top of 4.15
