Subject: [PATCH] dts: Add hogs for RP1 GPIO 46/48 on CM5
|
||||||
|
|
||||||
|
On Pi5 5, GPIOs 46/48 are made available on the 'CAM/DISP 1' connector as
|
||||||
|
'CD1_IO0_MICCLK'/'CD1_IO1_MICDAT1'. These GPIOs are not connected on
|
||||||
|
CM5.
|
||||||
|
|
||||||
|
Add hogs for GPIO 46/48 on CM5 to prevent camera drivers from
|
||||||
|
inadvertently using them when connected to 'CAM/DISP 1'
