[PATCH v3 00/14] drm/sun4i: Allwinner D1 Display Engine 2.0 Support

[PATCH v3 00/14] drm/sun4i: Allwinner D1 Display Engine 2.0 Support

[Samuel Holland]

This series adds binding and driver support for Display Engine 2.0
variant found in the Allwinner D1.

So far it has only been tested with HDMI. I will be sending the HDMI
support series separately, because the hardware comes with a brand new
custom HDMI PHY, which requires some refactoring to support cleanly.

This series was tested on A33, D1 and H3.

Changes in v3:
 - Drop redundant minItems and maxItems

Changes in v2:
 - New patch: I/O helper portability
 - Use Jernej's patches for mixer mode setting.
 - Use an enumeration for the ccsc value.

Jernej Skrabec (3):
  sun4i/drm: engine: Add mode_set callback
  sun4i/drm: backend: use mode_set engine callback
  sun4i/drm: sun8i: use mode_set engine callback

Samuel Holland (11):
  dt-bindings: display: Separate clock item lists by compatible
  dt-bindings: display: Add D1 display engine compatibles
  drm/sun4i: Remove obsolete references to PHYS_OFFSET
  drm/sun4i: hdmi: Use more portable I/O helpers
  drm/sun4i: Allow building the driver on RISC-V
  drm/sun4i: Allow VI layers to be primary planes
  drm/sun4i: csc: Add support for the new MMIO layout
  drm/sun4i: Add support for D1 mixers
  drm/sun4i: Add support for D1 TCON TOP
  drm/sun4i: Add support for D1 TCONs
  drm/sun4i: Add compatible for D1 display engine

[PATCH v3 01/14] dt-bindings: display: Separate clock item lists by compatible

[Samuel Holland]

So far, the binding and driver have relied on the fact that the H6
clocks are both a prefix and a subset of the R40 clocks. This allows
them to share the clocks/clock-names items and the clock-output-names
order between the hardware variants.

However, the D1 hardware has TCON TV0 and DSI, but no TCON TV1. This
cannot be supported by the existing scheme because it puts a gap in the
middle of the item lists. To prepare for adding D1 support, use separate
lists for variants with different combinations of clocks.

[PATCH v3 03/14] drm/sun4i: Remove obsolete references to PHYS_OFFSET

[Samuel Holland]

commit b4bdc4fbf8d0 ("soc: sunxi: Deal with the MBUS DMA offsets in a
central place") added a platform device notifier that sets the DMA
offset for all of the display engine frontend and backend devices.

The code applying the offset to DMA buffer physical addresses was then
removed from the backend driver in commit 756668ba682e ("drm/sun4i:
backend: Remove the MBUS quirks"), but the code subtracting PHYS_OFFSET
was left in the frontend driver.

As a result, the offset was applied twice in the frontend driver. This
likely went unnoticed because it only affects specific configurations
(scaling or certain pixel formats) where the frontend is used, on boards
with both one of these older SoCs and more than 1 GB of DRAM.

In addition, the references to PHYS_OFFSET prevent compiling the driver
on architectures where PHYS_OFFSET is not defined.

[PATCH v3 05/14] drm/sun4i: Allow building the driver on RISC-V

[Samuel Holland]

Allwinner D1 is a RISC-V SoC which contains a DE 2.0 engine. Let's
remove the dependency on a specific CPU architecture, so the driver can
be built wherever ARCH_SUNXI is selected.

[PATCH v3 06/14] sun4i/drm: engine: Add mode_set callback

[Samuel Holland]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

This optional callback is useful for setting properties which depends
only on current mode. Such properties are width, height and interlaced
output.

These properties are currently set in update layer callback for primary
plane which is less than ideal. More about that in follow up patches,
which will migrate that code to this newly defined callback.

[PATCH v3 07/14] sun4i/drm: backend: use mode_set engine callback

[Samuel Holland]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

Newly introduced mode_set callback in engine structure is a much better
place for setting backend output size and interlace mode for following
reasons:
1. Aforementioned properties change only when mode changes, so it's
   enough to be set only once per mode set. Currently it's done whenever
   properties of primary plane are changed.
2. It's assumed that primary plane will always cover whole screen. While
   this is true most of the time, it's not always. Planes are universal.
   There is no reason to add artificial limitation to primary plane.

[PATCH v3 07/14] sun4i/drm: backend: use mode_set engine callback

[Samuel Holland]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

Newly introduced mode_set callback in engine structure is a much better
place for setting backend output size and interlace mode for following
reasons:
1. Aforementioned properties change only when mode changes, so it's
   enough to be set only once per mode set. Currently it's done whenever
   properties of primary plane are changed.
2. It's assumed that primary plane will always cover whole screen. While
   this is true most of the time, it's not always. Planes are universal.
   There is no reason to add artificial limitation to primary plane.

[PATCH v3 08/14] sun4i/drm: sun8i: use mode_set engine callback

[Samuel Holland]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

Newly introduced mode_set callback in engine structure is a much better
place for setting mixer output size and interlace mode for the following
reasons:
1. Aforementioned properties change only when mode changes, so it's
   enough to be set only once per mode set. Currently it's done whenever
   properties of primary plane are changed.
2. It's assumed that primary plane will always cover whole screen. While
   this is true most of the time, it's not always. DE2/3 planes are
   universal and mostly equal in functionality. There is no reason to
   add artificial limitation to primary planes.
3. The current code only works for UI layers, but some mixers do not
   have any UI layers.

[PATCH v3 08/14] sun4i/drm: sun8i: use mode_set engine callback

[Samuel Holland]

From: Jernej Skrabec <jernej.skrabec@gmail.com>

Newly introduced mode_set callback in engine structure is a much better
place for setting mixer output size and interlace mode for the following
reasons:
1. Aforementioned properties change only when mode changes, so it's
   enough to be set only once per mode set. Currently it's done whenever
   properties of primary plane are changed.
2. It's assumed that primary plane will always cover whole screen. While
   this is true most of the time, it's not always. DE2/3 planes are
   universal and mostly equal in functionality. There is no reason to
   add artificial limitation to primary planes.
3. The current code only works for UI layers, but some mixers do not
   have any UI layers.

[PATCH v3 09/14] drm/sun4i: Allow VI layers to be primary planes

[Samuel Holland]

D1's mixer 1 has no UI layers, only a single VI layer. That means the
mixer can only be used if the primary plane comes from this VI layer.
Add the code to handle this case.

[PATCH v3 10/14] drm/sun4i: csc: Add support for the new MMIO layout

[Samuel Holland]

D1 changes the MMIO offsets for the CSC blocks in the first mixer. The
mixers' ccsc property is used as an index into the ccsc_base array. Use
an enumeration to describe this index, and add the new set of offsets.

Signed-off-by: Samuel Holland <samuel@sholland.org>

(no changes since v2)

Changes in v2:
 - Use an enumeration for the ccsc value.

[PATCH v3 11/14] drm/sun4i: Add support for D1 mixers

[Samuel Holland]

D1 has a display engine with the usual pair of mixers, albeit with
relatively few layers. In fact, D1 appears to be the first SoC to have
a mixer without any UI layers. Add support for these new variants.

[PATCH v3 12/14] drm/sun4i: Add support for D1 TCON TOP

[Samuel Holland]

D1 has a TCON TOP with TCON TV0 and DSI, but no TCON TV1. This puts the
DSI clock name at index 1 in clock-output-names. Support this by only
incrementing the index for clocks that are actually supported.

[PATCH v3 12/14] drm/sun4i: Add support for D1 TCON TOP

[Samuel Holland]

D1 has a TCON TOP with TCON TV0 and DSI, but no TCON TV1. This puts the
DSI clock name at index 1 in clock-output-names. Support this by only
incrementing the index for clocks that are actually supported.

[PATCH v3 13/14] drm/sun4i: Add support for D1 TCONs

[Samuel Holland]

D1 has a TCON TOP, so its quirks are similar to those for the R40 TCONs.
While there are some register changes, the part of the TCON TV supported
by the driver matches the R40 quirks, so that quirks structure can be
reused. D1 has the first supported TCON LCD with a TCON TOP, so the TCON
LCD needs a new quirks structure.

D1's TCON LCD hardware supports LVDS; in fact it provides dual-link LVDS
from a single TCON. However, it comes with a brand new LVDS PHY. Since
this PHY has not been tested, leave out LVDS driver support for now.

[PATCH v3 13/14] drm/sun4i: Add support for D1 TCONs

[Samuel Holland]

D1 has a TCON TOP, so its quirks are similar to those for the R40 TCONs.
While there are some register changes, the part of the TCON TV supported
by the driver matches the R40 quirks, so that quirks structure can be
reused. D1 has the first supported TCON LCD with a TCON TOP, so the TCON
LCD needs a new quirks structure.

D1's TCON LCD hardware supports LVDS; in fact it provides dual-link LVDS
from a single TCON. However, it comes with a brand new LVDS PHY. Since
this PHY has not been tested, leave out LVDS driver support for now.
