drm/meson: venc: include linux/bitfield.h

2023-06-02T13:47:52+00:00

Without this header, the use of FIELD_PREP() can cause a build failure:

drm/meson: add support for MIPI-DSI transceiver

2023-06-01T14:10:24+00:00

The Amlogic G12A/G12B/SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver
(ver 1.21a), with a custom glue managing the IP resets, clock and data
inputs similar to the DW-HDMI Glue on other Amlogic SoCs.

This adds support for the Glue managing the transceiver, mimicing the init
flow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver,
the digital D-PHY and the Analog PHY in the proper way.

An optional "MEAS" clock can be enabled to measure the delay between each
vsync feeding the DW-MIPI-DSI transceiver.

drm/meson: add DSI encoder

2023-06-01T14:10:23+00:00

This adds an encoder bridge designed to drive a MIPI-DSI display
by using the ENCL encoder through the internal MIPI DSI transceiver
connected to the output of the ENCL pixel encoder.

drm/meson: only use components with dw-hdmi

2023-06-01T14:10:22+00:00

Only DW-HDMI currently needs components since it reuses
the drm-meson driver context to access HHI registers (sic).

Once this is solved, we can get rid on components.

Until now, limit the components matching to the dw-hdmi compatibles
we know to require this hack, for other bridges simply use probe defer
instead and get over this components sitation.

The back story is that we simply cannot attach DSI adapters bridges
if we use components, only DSI panels, this is because we bind/unbind
the DSI controller at each drm-meson driver master bind tentative.
With this the I2C DSI bridge is unable to find the DSI controller
host and everything fails to probe.

This will simplify a lot adding new or older HDMI bridges.

drm/meson: fix unbind path if HDMI fails to bind

2023-06-01T14:10:21+00:00

If the case the HDMI controller fails to bind, we try to unbind
all components before calling drm_dev_put() which makes drm_bridge_detach()
crash because unbinding the HDMI controller frees the bridge memory.

The solution is the unbind all components at the end like in the remove
path.

drm/aperture: Remove primary argument

2023-04-16T12:17:41+00:00

Only really pci devices have a business setting this - it's for
figuring out whether the legacy vga stuff should be nuked too. And
with the preceding two patches those are all using the pci version of
this.

Which means for all other callers primary == false and we can remove
it now.

v2:
- Reorder to avoid compile fail (Thomas)
- Include gma500, which retained it's called to the non-pci version.

v4:
- fix Daniel's S-o-b address

v5:
- add back an S-o-b tag with Daniel's Intel address

Merge v6.3-rc4 into drm-next

2023-03-29T14:00:23+00:00

I just landed the fence deadline PR from Rob that a bunch of drivers
want/need to apply driver-specific patches. Backmerge -rc4 so that
they don't have to be stuck on -rc2 for no reason at all.
