Subject: [PATCH 1248/1350] dts: Add 'AI Camera' support
|
|
|
|
The AI Camera combines an IMX500 and a RP2040 GPIO bridge on a single
|
|
module. The Raspberry Pi camera regulator is used for both IMX500 and
|
|
RP2040. SPI, clocks, and reset (required by IMX500) are provided by the
|
|
RP2040 GPIO bridge.
