which are RGB.
Add support for the Wingtech CT2MHS01 hotspot, a Qualcomm mdm9650-based
device with a screen available for US$15-35. This device is often used
as a base platform for while labeled versions like the T-Mobile TMOHS1.
AT&T branded versions of the hotspot seem to be the most abundant.
The device has a framebuffer-driven screen at /dev/fb0 that behaves
similarly to the Orbic RC400L, although the userspace program
`displaygui` refreshes the screen significantly more often than on the
Orbic. This causes the green line on the screen to subtly flicker and
only be displayed during some frames. Subsequent work to fully control
the display without removing the OEM interface is desired.
