Subject: [PATCH] drm/dsi: Document the meaning and spec references for
|
|
MIPI_DSI_MODE_*
|
|
|
|
The MIPI_DSI_MODE_* flags have fairly terse descriptions and no reference
|
|
to the DSI specification as to their exact meaning. Usage has therefore
|
|
been rather fluid.
|
|
|
|
Extend the descriptions and provide references to the part of the
|
|
MIPI DSI specification regarding what they mean.
