Merge tag 'media/v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - Documentation for digital TV (both kAPI and uAPI) are now in sync with the implementation (except for legacy/deprecated ioctls). This is a major step, as there were always a gap there - New sensor driver: imx274 - New cec driver: cec-gpio - New platform driver for rockship rga and tegra CEC - New RC driver: tango-ir - Several cleanups at atomisp driver - Core improvements for RC, CEC, V4L2 async probing support and DVB - Lots of drivers cleanup, fixes and improvements. * tag 'media/v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (332 commits) dvb_frontend: don't use-after-free the frontend struct media: dib0700: fix invalid dvb_detach argument media: v4l2-ctrls: Don't validate BITMASK twice media: s5p-mfc: fix lockdep warning media: dvb-core: always call invoke_release() in fe_free() media: usb: dvb-usb-v2: dvb_usb_core: remove redundant code in dvb_usb_fe_sleep media: au0828: make const array addr_list static media: cx88: make const arrays default_addr_list and pvr2000_addr_list static media: drxd: make const array fastIncrDecLUT static media: usb: fix spelling mistake: "synchronuously" -> "synchronously" media: ddbridge: fix build warnings media: av7110: avoid 2038 overflow in debug print media: Don't do DMA on stack for firmware upload in the AS102 driver media: v4l: async: fix unregister for implicitly registered sub-device notifiers media: v4l: async: fix return of unitialized variable ret media: imx274: fix missing return assignment from call to imx274_mode_regs media: camss-vfe: always initialize reg at vfe_set_xbar_cfg() media: atomisp: make function calls cleaner media: atomisp: get rid of storage_class.h media: atomisp: get rid of wrong stddef.h include ...

+device-tree bindings for rockchip 2D raster graphic acceleration controller (RGA)
+
+RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
+graphics operations, such as point/line drawing, image scaling, rotation,
+BitBLT, alpha blending and image blur/sharpness.
+
+Required properties:
+- compatible: value should be one of the following
+ "rockchip,rk3288-rga";
+ "rockchip,rk3399-rga";
+
+- interrupts: RGA interrupt specifier.
+
+- clocks: phandle to RGA sclk/hclk/aclk clocks
+
+- clock-names: should be "aclk", "hclk" and "sclk"
+
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: should be "core", "axi" and "ahb"
+
+Example:
+SoC-specific DT entry:
+ rga: rga@ff680000 {
+ compatible = "rockchip,rk3399-rga";
+ reg = <0xff680000 0x10000>;
+ interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA_CORE>;
+ clock-names = "aclk", "hclk", "sclk";
+
+ resets = <&cru SRST_RGA_CORE>, <&cru SRST_A_RGA>, <&cru SRST_H_RGA>;
+ reset-names = "core, "axi", "ahb";
+ };
