Pull ARM SoC platform updates from Arnd Bergmann: "In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms. This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added. The main reason for this is that there's a removal of camera drivers for Freescale i.MX chips (driver was removed so the device registration isn't needed any more). There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff.

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:
|
|
- power-domains: 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.

Example:
|
|
|
|
SoC specific DT entry:
|
|
|
|
decon@13930000 {
|
|
compatible = "samsung,exynos7-decon";
|
|
interrupt-parent = <&combiner>;
|
|
reg = <0x13930000 0x1000>;
|
|
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";
|
|
status = "okay";
|
|
};
