Merge "ARM: dts: Document guidelines for DCS command timeout issue"

					byte 5, 6: 16 bits length in network byte order

					byte 7 and beyond: number byte of payload

Note, if a short DCS packet(i.e packet with Byte 0:dcs data type as 05) mentioned in

qcom,mdss-dsi-on-command/qcom,mdss-dsi-off-command stream fails to transmit,

then 3 options can be tried.

	1. Send the packet as a long packet instead

				Byte 0: dcs data type = 05 (DCS short Packet)

				Byte 0: dcs data type = 29 (DCS long Packet)

	2. Send the packet in one burst by prepending with the next packet in packet stream

				Byte 1 = 01 (indicates this is an individual packet)

				Byte 1 = 00 (indicates this will be appended to the next

					     individual packet in the packet stream)

	3. Prepend a NULL packet to the short packet and send both in one burst instead of

	   combining multiple short packets and sending them in one burst.

Optional properties:

- qcom,mdss-dsi-panel-name:		A string used as a descriptive name of the panel

- qcom,cont-splash-enabled:		Boolean used to enable continuous splash mode.
