Merge tag 'imx-dt-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt
Pull "The i.MX device tree changes for 3.19" from Shawn Guo: - Device additions for board vf610-colibri, pwm, backlight, I2C, RTC, ADC etc. - Update i.MX6 phyFLEX board to include PCIe, CAN and audio support - Improve SSI clocks description for i.MX5 platforms - Add ENET2 support for imx6sx-sdb board - Add device tree source for LS1021A SoC, board QDS and TWR - Enable cpufreq support for i.MX53 - Enable VPU device support for i.MX6QDL - Enable poweroff support for i.MX6 SoCs - Add support for TBS2910 Matrix ARM mini PC which is built on i.MX6Q - Create generic base device trees for Vybrid and add support for Colibri VF50 Note: the change set is built on top of imx-soc-3.19 to resolve the dependency that "ARM: dts: imx53: add cpufreq-dt support" uses the clock define IMX5_CLK_ARM that is added by "ARM: imx53: clk: add ARM clock". * tag 'imx-dt-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: (51 commits) ARM: dts: imx6q-tbs2910: Enable snvs-poweroff ARM: dts: imx6: add pm_power_off support for i.mx6 chips ARM: dts: vf-colibri: add USB regulators ARM: dts: imx6: phyFLEX: Add CAN support ARM: dts: imx6: phyFLEX: Add PCIe ARM: dts: imx6: phyFLEX: Set correct interrupt for pmic ARM: dts: imx6: phyFLEX: Enable gpmi in module file ARM: dts: imx6: phyFLEX: set nodes in alphabetical order ARM: dts: vf-colibri-eval-v3.dts: Enable ST-M41T0M6 RTC ARM: dts: vf-colibri: Add I2C support ARM: dts: imx6qdl: Enable CODA960 VPU ARM: dts: imx6q-tbs2910: Remove unneeded 'fsl,mode' property ARM: dts: vf610: enable USB misc/phy nodes where necessary ARM: dts: vf610: use new GPIO support ARM: dts: pbab01: enable I2S audio on phyFLEX-i.MX6 boards ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02 ARM: dts: vf500-colibri: add Colibri VF50 support ARM: dts: vf610: create generic base device trees ARM: dts: vf610: assign oscillator to clock module dt-bindings: arm: add Freescale LS1021A SoC device tree binding ...
