Subject: [PATCH 28/36] ARM: bcm2835: Add devicetree for the Raspberry Pi 3.
|
|
|
df68cbf |
|
|
|
df68cbf |
For now this doesn't support the new hardware present on the Pi 3 (BT,
|
|
|
df68cbf |
wifi, GPIO expander). Since the GPIO expander isn't supported, we
|
|
|
df68cbf |
also don't have the LEDs like the other board files do.
