Subject: [PATCH v3 2/2] drm/panel: simple: Add support BOE nv101wxmn51
10.1WXGA is a color active matrix TFT LCD module using amorphous silicon
TFT's as an active switching devices. It can be supported by the
simple-panel driver.
Read the panel default edid information:
EDID MODE DETAILS
name = <NULL>
pixel_clock = 71900
lvds_dual_channel = 0
refresh = 0
ha = 1280
hbl = 160
hso = 48
hspw = 32
hborder = 0
va = 800
vbl = 32
vso = 3
vspw = 5
vborder = 0
phsync = +
pvsync = -
x_mm = 0
y_mm = 0
drm_display_mode
.hdisplay = 1280
.hsync_start = 1328
.hsync_end = 1360
.htotal = 1440
.vdisplay = 800
.vsync_start = 803
.vsync_end = 808
.vtotal = 832
There are two modes in the edid:
Detailed mode1: Clock 71.900 MHz, 216 mm x 135 mm
1280 1328 1360 1440 hborder 0
800 803 808 832 vborder 0
+hsync -vsync
Detailed mode2: Clock 57.500 MHz, 216 mm x 135 mm
1280 1328 1360 1440 hborder 0
800 803 808 832 vborder 0
+hsync -vsync
Add the both edid to support more modes for BOE nv101wxmn51.

Changes in v3:
- As Stéphane commented on https://patchwork.kernel.org/patch/9465911,
add downclock mode for edid.
Changes in v2:
- fix the vsync_start and vsync_end from the edid.
- change the commit.
