Subject: [PATCH 204/703] arm: dt: Add DT overlays for ADV7282M, OV5647, and
|
|
TC358743
|
|
|
|
DT overlays to setup the above devices via i2c_arm and csi1.
|
|
(This currently does not use the i2c-mux-pinctrl driver to
|
|
dynamically switch the pinctrl)
|
|
|
|
tc358743 is tc358743 running at a default link frequency
|
|
of 972Mbit/s. This allows up to 1080P50 UYVY on 2 lanes.
|
|
There is a parameter to allow changing the link frequency,
|
|
but the only values supported by the driver are 297000000
|
|
for 594Mbit/s, and 486000000 for 972Mbit/s.
|
|
There is also a parameter to enable 4 lane mode (only
|
|
relevant to Compute Module (1 or 3) csi1).
|
|
|
|
tc358743-audio overlay enables I2S audio from the TC358743
|
|
to the Pi (SD to GPIO20, SCK to GPIO18, WFS to GPIO19).
|
|
|
|
ADV7282M is the Analog Devices analogue video to CSI bridge
|
|
chip.
|
|
|
|
OV5647 is the Pi V1.3 camera module. Currently the driver only
|
|
supports VGA 8bit Bayer and very few controls.
