Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/g…

…it/tomba/linux Pull fbdev changes from Tomi Valkeinen: "Nothing particularly stands out in this pull request. The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons. There are also a few commits that have changes to arch/arm/mach-at91 and arch/avr32, which have been acked by the maintainers" * tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux: (143 commits) fb: reorder the lock sequence to fix potential dead lock fbdev: shmobile-lcdcfb: Convert to clk_prepare/unprepare fbdev: shmobile-hdmi: Convert to clk_prepare/unprepare omapdss: Add new panel driver for Topolly td028ttec1 LCD. video: exynos_mipi_dsi: Unlock the mutex before returning video: da8xx-fb: remove unwanted define video: Remove unnecessary semicolons simplefb: use write-combined remapping simplefb: fix unmapping fb during destruction OMAPDSS: connector-dvi: fix releasing i2c_adapter OMAPDSS: DSI: fix perf measuring ifdefs framebuffer: Use fb_<level> framebuffer: Add fb_<level> convenience logging macros efifb: prevent null-deref when iterating dmi_list fbdev: fix error return code in metronomefb_probe() video: xilinxfb: Fix for "Use standard variable name convention" OMAPDSS: Fix de_level in videomode_to_omap_video_timings() video: xilinxfb: Simplify error path video: xilinxfb: Use devm_kzalloc instead of kzalloc video: xilinxfb: Use standard variable name convention ...

+Atmel LCDC Framebuffer
+-----------------------------------------------------
+
+Required properties:
+- compatible :
+	"atmel,at91sam9261-lcdc" , 
+	"atmel,at91sam9263-lcdc" ,
+	"atmel,at91sam9g10-lcdc" ,
+	"atmel,at91sam9g45-lcdc" ,
+	"atmel,at91sam9g45es-lcdc" ,
+	"atmel,at91sam9rl-lcdc" ,
+	"atmel,at32ap-lcdc"
+- reg : Should contain 1 register ranges(address and length)
+- interrupts : framebuffer controller interrupt
+- display: a phandle pointing to the display node
+
+Required nodes:
+- display: a display node is required to initialize the lcd panel
+	This should be in the board dts.
+- default-mode: a videomode within the display with timing parameters
+	as specified below.
+
+Example:
+
+	fb0: fb@0x00500000 {
+		compatible = "atmel,at91sam9g45-lcdc";
+		reg = <0x00500000 0x1000>;
+		interrupts = <23 3 0>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&pinctrl_fb>;
+		display = <&display0>;
+		status = "okay";
+		#address-cells = <1>;
+		#size-cells = <1>;
+
+	};
+
+Atmel LCDC Display
+-----------------------------------------------------
+Required properties (as per of_videomode_helper):
+
+ - atmel,dmacon: dma controler configuration
+ - atmel,lcdcon2: lcd controler configuration
+ - atmel,guard-time: lcd guard time (Delay in frame periods)
+ - bits-per-pixel: lcd panel bit-depth.
+
+Optional properties (as per of_videomode_helper):
+ - atmel,lcdcon-backlight: enable backlight
+ - atmel,lcd-wiring-mode: lcd wiring mode "RGB" or "BRG"
+ - atmel,power-control-gpio: gpio to power on or off the LCD (as many as needed)
+
+Example:
+	display0: display {
+		bits-per-pixel = <32>;
+		atmel,lcdcon-backlight;
+		atmel,dmacon = <0x1>;
+		atmel,lcdcon2 = <0x80008002>;
+		atmel,guard-time = <9>;
+		atmel,lcd-wiring-mode = <1>;
+
+		display-timings {
+			native-mode = <&timing0>;
+			timing0: timing0 {
+				clock-frequency = <9000000>;
+				hactive = <480>;
+				vactive = <272>;
+				hback-porch = <1>;
+				hfront-porch = <1>;
+				vback-porch = <40>;
+				vfront-porch = <1>;
+				hsync-len = <45>;
+				vsync-len = <1>;
+			};
+		};
