Subject: [PATCH 1324/1350] dts: bcm2712-rpi: Add aliases for the CSI/DSI I2Cs
|
|
|
|
Older Pis arrange that the camera I2C ports appear as /dev/i2c-10. Add
|
|
aliases so that on the Pi 5 family, i2c_csi_dsi0 becomes i2c-10 and
|
|
i2c_csi_dsi1 becomes i2c-11. Only the I2C buses that appear on the
|
|
40-pin header, i.e. I2C0 to I2C3, get a low bus number.
|
|
|
|
Also add hints for our udev rules about which symlinks to create for
|
|
backwards-compatibility with the previous bus numbers. Note that
|
|
lower numbers have priority, so i2c-0 on CM5 masks i2c-11, forcing
|
|
i2c-11 to be a symlink to i2c-0, not vice versa.
