Subject: [PATCH 4/6] drm: Check for "panel orientation" connector property
|
|
|
a802d9 |
|
|
|
a802d9 |
On some devices the LCD panel is mounted in the casing in such a way
|
|
|
a802d9 |
that the up/top side of the panel does not match with the top side of
|
|
|
a802d9 |
the device (e.g. it is mounted upside-down).
|
|
|
a802d9 |
|
|
|
a802d9 |
Kernel 4.16 introduces a new "panel-orientation" property on the drm
|
|
|
a802d9 |
connector which allows modesetting applications / code to check for
|
|
|
a802d9 |
such LCD panels.
|
|
|
a802d9 |
|
|
|
a802d9 |
This commit adds support for this new property and passes this to the
|
|
|
a802d9 |
pixel_buffer code using the new ply_pixel_buffer_new_with_device_rotation
|
|
|
a802d9 |
method, so that the pixel_buffer code will automatically rotate the
|
|
|
a802d9 |
image to correct for the panel orientation.
