The HannStar HSD070PWW1 LVDS panel data sheet lists allowed ranges
additionally to the typical values for pixel clock rate (64.3-82 MHz)
and blanking intervals (54-681 clock cycles horizontally, 3-23 lines
vertically).
This patch replaces this panel's display mode with the display timing
information to describe acceptable timings. Since the HSYNC and VSYNC
are unused, the distribution between front porches, back porches, and
sync pulse lengths was chosen at will.

Before shutting down the display using the DCS display_off command, wait
for 4 frames according to the datasheet.
Furthermore, after enabling the power supply, the supply voltage needs
around 10 ms to settle. After that, another 120 ms is required before a
DCS exit_sleep_mode command can be sent.
While at it, no longer send the DCS soft_reset command. This is totally
unnecessary because we've just powered up the display, hence it will be
in a reset state already.

Pull drm updates from Dave Airlie:
"Highlights:
- AMD KFD driver merge
This is the AMD HSA interface for exposing a lowlevel interface for
GPGPU use. They have an open source userspace built on top of this
interface, and the code looks as good as it was going to get out of
tree.
- Initial atomic modesetting work
The need for an atomic modesetting interface to allow userspace to
try and send a complete set of modesetting state to the driver has
arisen, and been suffering from neglect this past year. No more,
the start of the common code and changes for msm driver to use it
are in this tree. Ongoing work to get the userspace ioctl finished
and the code clean will probably wait until next kernel.
- DisplayID 1.3 and tiled monitor exposed to userspace.
Tiled monitor property is now exposed for userspace to make use of.
- Rockchip drm driver merged.
- imx gpu driver moved out of staging

This panel requires dual-channel mode. The device accepts command-mode

the controllers that gang up to provide the dual-channel DSI host.

The S6E8AA0 driver relies on the old asymmetric API and there's concern
