Subject: [PATCH] dtoverlays: Create Pi5 variant of tc358743 overlay
|
|
|
|
The Pi0-4 variant wants to change the compatible string for
|
|
the CSI2 node to "brcm,bcm2835-unicam-legacy" to disable Media
|
|
Controller by default, which would switch to Unicam when Pi5 needs
|
|
the CFE driver.
|
|
|
|
Split the overlay into an include and base pi0-4 and pi5 overlay
|
|
files
