-Subject: [PATCH] dt-bindings: i2c: brcmstb: Add BCM2711 BSC/AUTO-I2C
- binding
-
-The HDMI blocks in the BCM2771 have an i2c controller to retrieve the
-EDID. This block is split into two parts, the BSC and the AUTO_I2C,
-lying in two separate register areas.
-
-The AUTO_I2C block has a mailbox-like interface and will take away the
-BSC control from the CPU if enabled. However, the BSC is the actually
-the same controller than the one supported by the brcmstb driver, and
-the AUTO_I2C doesn't really bring any immediate benefit.
-
-We can model it in the DT as a single device with two register range,
-which will allow us to use or or the other in the driver without
-changing anything in the DT.
