Merge branch 'imx/dt/for-3.5' of git://git.linaro.org/people/shawnguo/linux-2.6.git into next/dt2
Shawn Guo <shawn.guo@linaro.org> writes: I chose to base it on Sascha's imx-common-clk series than -rc, because otherwise it will keep patching clock file that has been removed by imx-common-clk series. It also depends on imx-pinctrl pull-request I just sent to be functional. Note: when imx-common-clk and imx-pinctrl get merged together, the following files will have conflicts. But the conflicts should not be so hard to resolve. [arnd: resolved those merge conflicts by pulling pinctrl branch] * imx/dt: (24 commits) ARM: dts: imx53-qsb: enable audio support ARM: dts: imx51-babbage: enable audio support ARM: imx: add audio codec clk lookup for imx53-qsb ARM: imx: add audmux pad setting for imx51-babbage ARM: imx: add more imx5 ssi clocks ARM: dts: imx53-qsb: Add Dialog DA9053 PMIC support ARM: dts: imx6q-sabrelite: add serial2 pinctrl support ARM: dts: imx6q-sabrelite: add sound device imx6q-sabrelite-sgtl5000 ARM: imx6q_sabrelite: clk_register_clkdev cko1 for sgtl5000 ARM: imx6q: add ssi1_ipg clk_lookup ARM: dts: imx6q-sabrelite: add audmux pinctrl support ARM: dts: imx6q-sabrelite: add i2c1 pinctrl support ARM: dts: imx6q-sabrelite: add audmux device ARM: dts: imx6q-sabrelite: add ssi device ARM: dts: imx6q-arm2: add pinctrl state for usdhc ARM: imx6: Add UART2 for low-level debug ARM: imx6q: register phy fixup only when CONFIG_PHYLIB is enabled ARM: imx6q: move imx6q_sabrelite specific code to a dedicated function ARM: dts: imx6q-sabrelite: Add SPI NOR support ARM: dts: Add basic support for imx6q-sabresd ...
