-Subject: [PATCH] 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.
