[Intel-gfx] [PATCH 0/7] Updated MIPI sequence for BYT

[Shobhit Kumar]

Hi,
The changes in DSI sequence are as suggested by HW and SV teams. Notable
difference apart form few WAs is that for MIPI it is suggetsed that the
PORT is enabled before PIPE and PLANE. The patch makes these changes.
So few sequence changes, few workarounds and few new feature support like
Clockstop.

A generic panel driver to enable MIPI is planned in next patchset

Known issue - 
Today the upstream kernel does not have PMIC driver amd these patches works if 
UEFI BIOS enables MIPI and reuse  BKL_EN, PANEL_EN from there, but during
suspend/resume things will still fail.

Regards
Shobhit
