In preparation of new sdm660-mainline kernel release all downstream ports will become irrelevant. If needed, downstream port can still be chosen as 'xiaomi-lavender-downstream' during pmbootstrap init.

Subject: [PATCH] mdss: update fb mode at mdss_panelinfo_to_fb_var to fix Xorg
|
|
|
|
When mdss_panelinfo_to_fb_var is called at
|
|
screen unblank it updates the values in fb_info->var,
|
|
meanwhile the fb_info->mode and modelist remain with old
|
|
values set at registering the fb causing mismatch when
|
|
Xorg attempts to set mode.
