Add proper named constants for the Synaptics SYN43711 (AP6611S)
WiFi chip used on Orange Pi 5 Ultra:
- SDIO_VENDOR_ID_SYNAPTICS (0x06cb) in sdio_ids.h
- SDIO_DEVICE_ID_BROADCOM_CYPRESS_43711 (0xaabf) in sdio_ids.h
- CY_CC_43711_CHIP_ID (43711) in brcm_hw_ids.h
Driver changes:
- bcmsdh.c: bind both Broadcom (0x02d0) and Synaptics (0x06cb) vendors
- chip.c: add RAM base 0x170000 (from bcmdhd CR4_43711_RAM_BASE)
- sdio.c: firmware mapping entry for brcmfmac43711-sdio
In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.
In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.
Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.

Add an atomic variant of the ->detect callback and a new helper to call
the hook while passing an optional drm_modeset_acquire_ctx reference.
When both ->detect_ctx and ->detect are defined, the latter is ignored.
If acquire_ctx is unset, the function takes care of the locking,
while also handling EDEADLK.

with dp to hdmi converter bridge present. By enabling this, we can use the 2nd hdmi as a secondary display for AOSP(or even primary if first hdmi port is not used).
These modifications are from Detlev Casanova from collabora, who is currently developing HW stateless video decoders drivers for rk3588 and rk3576 SoC's . Using his patch for linux and ffmpeg using v4l2 requests and my patches for ffmpeg_codec2, I was able to get 4k@25 fps - 8-bit, running( HEVC and h.264) but still yet to optimise it and need to add hw decoders for vp9, av1, vp8 etc. NOTE - This is a testing build and might cause kernel panics.
