Merge "Merge remote-tracking branch 'quic/dev/msm-4.14-display' into msm-4.14"

Required properties:

- compatible:		"qcom,dp-mst-sim"

Optional properties:

- qcom,dpcd-max-rate:     A u32 property defines dpcd reg 0x1.

- qcom,dpcd-max-lane:     A u32 property defines dpcd reg 0x2.

- qcom,dpcd-mst:          A u32 property defines dpcd reg 0x21.

- qcom,dpcd-regs:         A <addr,val> array property defines dpcd reg addr

                          and val.

- qcom,voltage-swing:     A u32 property that overwrite dpcd reg 0x103~0x106.

- qcom,pre-emphasis:      A u32 property that overwrite dpcd reg 0x103~0x106.

- qcom,link-training-cnt: A u32 property defines physical link training cnt

                          before switching to simulation mode.

- qcom,skip-edid:         A boolean property defines if edid will read from

                          internal edid buffer.

- qcom,skip-dpcd-read:    A boolean property defines if dpcd will read from

                          internal dpcd buffer.

- qcom,skip-link-training: A boolean property defines if link training will

                          be skipped.

- qcom,skip-dpcd-write:   A boolean property defines if dpcd write will be

                          ignored.

- qcom,skip-hpd:          A boolean property defines if HPD will be ignored

                          and always set high.

- qcom,skip-mst:          A boolean property defines if MST sideband message

                          need to be simulated.

Each child node represents a port at root branch, with properties:

- qcom,edid:               A u8 array property defines EDID raw data. Once

                           defined, below properties will be ignored. For any

                           mode with horizontal width > 4095, only EDID raw

                           data format is supported.

- qcom,mode-h-active:      A u32 property defines the horizontal active size.

- qcom,mode-h-front-porch: A u32 property defines the horizontal front porch.

- qcom,mode-h-pulse-width: A u32 property defines the horizontal pulse.

- qcom,dp-aux-bridge:		phandle for dp aux bridge module, for 3rd party dp bridge only.

- qcom,dp-aux-bridge-sim:	phandle for dp aux bridge module, for internal mst debug simulation only.

- qcom,dp-force-bond-mode:	Ignore tile information from EDID and force DP to work in bond mode.

- qcom,dp-force-connect-mode:	Boolean to specify if dp is in always-connected mode, only set

				when qcom,dp-aux-bridge is defined. Once set, dp will always

				report connected state to user. When HPD is high, mode from sink

				will be reported. When HPD is low, mode from dp-aux-bridge

				simulator will be reported.

- qcom,bond-dual-ctrl:		u32 array to specify the cell-index of the two DP controllers that support bond mode.

				The first controller in the array is the bond master. Driver will switch to bond mode

				if both DP controllers are connected to the same dual DP input monitor.
