drm/exynos: Add DECON driver
This patch is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git DECON(Display and Enhancement Controller) is the new IP in exynos7 SOC for generating video signals using pixel data. DECON driver can be used to drive 2 different interfaces on Exynos7: DECON-INT(video controller) and DECON-EXT(Mixer for HDMI) The existing FIMD driver code was used as a template to create DECON driver. Only DECON-INT is supported as of now, and DECON-EXT support will be added later. The current version of the driver supports video mode displays. Changelog v2: - Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON.

Device-Tree bindings for Samsung Exynos7 SoC display controller (DECON)
|
||||
|
||||
DECON (Display and Enhancement Controller) is the Display Controller for the
|
||||
Exynos7 series of SoCs which transfers the image data from a video memory
|
||||
buffer to an external LCD interface.
|
||||
|
||||
Required properties:
|
||||
- compatible: value should be "samsung,exynos7-decon";
|
||||
|
||||
- reg: physical base address and length of the DECON registers set.
|
||||
|
||||
- interrupt-parent: should be the phandle of the decon controller's
|
||||
parent interrupt controller.
|
||||
|
||||
- interrupts: should contain a list of all DECON IP block interrupts in the
|
||||
order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier
|
||||
format depends on the interrupt controller used.
|
||||
|
||||
- interrupt-names: should contain the interrupt names: "fifo", "vsync",
|
||||
"lcd_sys", in the same order as they were listed in the interrupts
|
||||
property.
|
||||
|
||||
- pinctrl-0: pin control group to be used for this controller.
|
||||
|
||||
- pinctrl-names: must contain a "default" entry.
|
||||
|
||||
- clocks: must include clock specifiers corresponding to entries in the
|
||||
clock-names property.
|
||||
|
||||
- clock-names: list of clock names sorted in the same order as the clocks
|
||||
property. Must contain "pclk_decon0", "aclk_decon0",
|
||||
"decon0_eclk", "decon0_vclk".
|
||||
- i80-if-timings: timing configuration for lcd i80 interface support.
|
||||
|
||||
Optional Properties:
|
||||
- samsung,power-domain: a phandle to DECON power domain node.
|
||||
- display-timings: timing settings for DECON, as described in document [1].
|
||||
Can be used in case timings cannot be provided otherwise
|
||||
or to override timings provided by the panel.

||||
interrupt-names = "lcd_sys", "vsync", "fifo";
|
||||
interrupts = <0 188 0>, <0 189 0>, <0 190 0>;
|
||||
clocks = <&clock_disp PCLK_DECON_INT>,
|
||||
<&clock_disp ACLK_DECON_INT>,
|
||||
<&clock_disp SCLK_DECON_INT_ECLK>,
|
||||
<&clock_disp SCLK_DECON_INT_EXTCLKPLL>;
|
||||
clock-names = "pclk_decon0", "aclk_decon0", "decon0_eclk",
|
||||
"decon0_vclk";
|
||||
status = "disabled";
|
||||
};
|
||||
|
||||
Board specific DT entry:
|
||||
|
||||
decon@13930000 {
|
||||
pinctrl-0 = <&lcd_clk &pwm1_out>;
|
||||
pinctrl-names = "default";
