Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx. Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y) Runtime-tested: bcm2708, bcm2710 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 354/454] drm/vc4: Advertise supported modifiers for planes
|
|
|
|
The IN_FORMATS blob allows the kernel to advertise to userspace which
|
|
format/modifier combinations are supported, per plane. Use this to
|
|
advertise that we support both T_TILED and linear.
|
|
|
|
v2:
|
|
- Only advertise T_TILED for RGB (Eric)
|
|
- Actually turn on allow_fb_modifiers (Eric)
