Subject[PATCH] drm: remove zte display driver
Date
From: Arnd Bergmann <arnd@arndb.de>

The zte zx platform is getting removed, so this driver is no
longer needed.

-ZTE VOU Display Controller
-
-This is a display controller found on ZTE ZX296718 SoC. It includes multiple
-Graphic Layer (GL) and Video Layer (VL), two Mixers/Channels, and a few blocks
-handling scaling, color space conversion etc. VOU also integrates the support
-for typical output devices, like HDMI, TV Encoder, VGA, and RGB LCD.
-
-* Master VOU node
-
-It must be the parent node of all the sub-device nodes.
-
-Required properties:
- - compatible: should be "zte,zx296718-vou"
- - #address-cells: should be <1>
- - #size-cells: should be <1>
- - ranges: list of address translations between VOU and sub-devices
-
-* VOU DPC device
-
-Required properties:
- - compatible: should be "zte,zx296718-dpc"
- - reg: Physical base address and length of DPC register regions, one for each
- entry in 'reg-names'
- - reg-names: The names of register regions. The following regions are required:
- "osd"
- "timing_ctrl"
- "dtrc"
- "vou_ctrl"
- "otfppu"
- - interrupts: VOU DPC interrupt number to CPU
- - clocks: A list of phandle + clock-specifier pairs, one for each entry
- in 'clock-names'
- - clock-names: A list of clock names. The following clocks are required:
- "aclk"
- "ppu_wclk"
- "main_wclk"
- "aux_wclk"
-
-* HDMI output device
-
-Required properties:
- - compatible: should be "zte,zx296718-hdmi"
- - reg: Physical base address and length of the HDMI device IO region
- - interrupts : HDMI interrupt number to CPU
- - clocks: A list of phandle + clock-specifier pairs, one for each entry
- in 'clock-names'
- - clock-names: A list of clock names. The following clocks are required:
- "osc_cec"
- "osc_clk"
- "xclk"
-
-* TV Encoder output device
-
-Required properties:
- - compatible: should be "zte,zx296718-tvenc"
- - reg: Physical base address and length of the TVENC device IO region
- - zte,tvenc-power-control: the phandle to SYSCTRL block followed by two
- integer cells. The first cell is the offset of SYSCTRL register used
- to control TV Encoder DAC power, and the second cell is the bit mask.
-
-* VGA output device
-
-Required properties:
- - compatible: should be "zte,zx296718-vga"
- - reg: Physical base address and length of the VGA device IO region
- - interrupts : VGA interrupt number to CPU
- - clocks: Phandle with clock-specifier pointing to VGA I2C clock.
- - clock-names: Must be "i2c_wclk".
- - zte,vga-power-control: the phandle to SYSCTRL block followed by two
- integer cells. The first cell is the offset of SYSCTRL register used
- to control VGA DAC power, and the second cell is the bit mask.
-
-Example:
-
-vou: vou@1440000 {
- compatible = "zte,zx296718-vou";
- #address-cells = <1>;
- #size-cells = <1>;
- ranges = <0 0x1440000 0x10000>;
-

- <0x5000 0x1000>, <0x6000 0x1000>,
- <0xa000 0x1000>;
- reg-names = "osd", "timing_ctrl",
