exynos_dp.txt (3478B)

      1The Exynos display port interface should be configured based on
      2the type of panel connected to it.
      3
      4We use two nodes:
      5	-dp-controller node
      6	-dptx-phy node(defined inside dp-controller node)
      7
      8For the DP-PHY initialization, we use the dptx-phy node.
      9Required properties for dptx-phy: deprecated, use phys and phy-names
     10	-reg: deprecated
     11		Base address of DP PHY register.
     12	-samsung,enable-mask: deprecated
     13		The bit-mask used to enable/disable DP PHY.
     14
     15For the Panel initialization, we read data from dp-controller node.
     16Required properties for dp-controller:
     17	-compatible:
     18		should be "samsung,exynos5-dp".
     19	-reg:
     20		physical base address of the controller and length
     21		of memory mapped region.
     22	-interrupts:
     23		interrupt combiner values.
     24	-clocks:
     25		from common clock binding: handle to dp clock.
     26	-clock-names:
     27		from common clock binding: Shall be "dp".
     28	-phys:
     29		from general PHY binding: the phandle for the PHY device.
     30	-phy-names:
     31		from general PHY binding: Should be "dp".
     32
     33Optional properties for dp-controller:
     34	-interlaced:
     35		interlace scan mode.
     36			Progressive if defined, Interlaced if not defined
     37	-vsync-active-high:
     38		VSYNC polarity configuration.
     39			High if defined, Low if not defined
     40	-hsync-active-high:
     41		HSYNC polarity configuration.
     42			High if defined, Low if not defined
     43	-samsung,hpd-gpio:
     44		Hotplug detect GPIO.
     45			Indicates which GPIO should be used for hotplug
     46			detection
     47	-video interfaces: Device node can contain video interface port
     48			nodes according to [1].
     49	- display-timings: timings for the connected panel as described by
     50		Documentation/devicetree/bindings/display/panel/display-timing.txt
     51
     52For the below properties, please refer to Analogix DP binding document:
     53 * Documentation/devicetree/bindings/display/bridge/analogix_dp.txt
     54	-phys (required)
     55	-phy-names (required)
     56	-hpd-gpios (optional)
     57	 force-hpd (optional)
     58
     59Deprecated properties for DisplayPort:
     60-interlaced:            deprecated prop that can parsed from drm_display_mode.
     61-vsync-active-high:     deprecated prop that can parsed from drm_display_mode.
     62-hsync-active-high:     deprecated prop that can parsed from drm_display_mode.
     63-samsung,ycbcr-coeff:   deprecated prop that can parsed from drm_display_mode.
     64-samsung,dynamic-range: deprecated prop that can parsed from drm_display_mode.
     65-samsung,color-space:   deprecated prop that can parsed from drm_display_info.
     66-samsung,color-depth:   deprecated prop that can parsed from drm_display_info.
     67-samsung,link-rate:     deprecated prop that can reading from monitor by dpcd method.
     68-samsung,lane-count:    deprecated prop that can reading from monitor by dpcd method.
     69-samsung,hpd-gpio:      deprecated name for hpd-gpios.
