drm/amdgpu: clean wptr on wb when gpu recovery

The TDR will be randomly failed due to compute ring
test failure. If the compute ring wptr & 0x7ff(ring_buf_mask)
is 0x100 then after map mqd the compute ring rptr will be
synced with 0x100. And the ring test packet size is also 0x100.
Then after invocation of amdgpu_ring_commit, the cp will not
really handle the packet on the ring buffer because rptr is equal to wptr.

The previous way of using SDMA queue count to infer whether we should unmap

drm/radeon: Inline drm_get_pci_dev

It's the last user, and more importantly, it's the last non-legacy
user of anything in drm_pci.c.

The only tricky bit is the agp initialization. But a close look shows
that radeon does not use the drm_agp midlayer (the main use of that is
drm_bufs for legacy drivers), and instead could use the agp subsystem
directly (like nouveau does already). Hence we can just pull this in
too.

A further step would be to entirely drop the use of drm_device->agp,
but feels like too much churn just for this patch.

drm/amdgpu: Drop DRIVER_USE_AGP

call drm_get_pci_dev(). Which amdgpu stopped doing with

    drm/amdgpu: drop deprecated drm_get_pci_dev and drm_put_dev

No idea whether this was intentional or accidental breakage, but I
guess anyone who manages to boot a this modern gpu behind an agp
bridge deserves a price. A price I never expect anyone to ever collect

drm/omap: hdmi4: Move mode set, enable and disable operations to bridge

Move the omap_dss_device .set_timings(), .enable() and .disable()
operations to the drm_bridge functions. As the drm_bridge for the HDMI
encoder is unconditionally registered and attached, those operations
will be called at the appropriate time.

The omapdss device .set_infoframe() and .set_hdmi_mode() operations have
no equivalent in drm_bridge. Thir content is thus moved to the bridge
.enable() operation as the data they store is not needed before the HDMI
encoder gets enabled.

drm/omap: hdmi5: Register a drm_bridge for EDID read

In order to integrate with a chain of drm_bridge, the internal HDMI5
encoder has to expose the EDID read operation through the drm_bridge
API. Register a bridge at initialisation time to do so.

For the time being make the next bridge in the chain optional as the
HDMI output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.

drm/omap: hdmi5: Rework EDID read to isolate data read

In preparation of adding DRM bridge support to the hdmi5 encoder code,
rework the EDID read to isolate data read.

The hdmi_read_edid() function is the main entry point. It performs all
initialisation steps required prior to reading the EDID (such as
ensuring the device is powered on), as well as corresponding cleanup
steps afterwards. EDID read itself is handled by hdmi_read_edid_data()
that calls the hdmi5_core_ddc_read() function to read individual blocks.

This new code architecture will allow reusing hdmi_read_edid() and
hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while
swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid()
function.

drm/omap: Add infrastructure to support drm_bridge local to DSS outputs

In order to support drm_bridge-based pipeline, the internal HDMI
encoders will need to expose the EDID read operation through the
drm_bridge API, and thus to expose a drm_bridge instance corresponding
to the encoder. The HDMI encoders are however handled as omap_dss_device
instances, which conflicts with this requirement.

In order to move forward with the drm_bridge transition, add support for
creating drm_bridge instances local to DSS outputs. If a local bridge is
passed to the omapdss_device_init_output() function, it is used as the
first bridge in the chain, and the omap_dss_device.next_bridge field is
set to the next bridge for the use of the internal encoders' bridges.

drm/omap: dss: Fix output next device lookup in DT

The DSS core looks up the next device connected to an output by
traversing the OF graph. It currently hardcodes the local port number to
0, which breaks any output with a different port number (SDI on OMAP3
and any DPI output but the first one). Fix this by repurposing the
currently unused of_ports bitmask in omap_dss_device with an of_port
output port number, and use it to traverse the OF graph.
