Merge tag 'omap-for-v4.5/81xx-dts-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
Pull "reworked dts changes for ti81xx devices and minimal dra62x j5ec-evm support" from Tony Lindgren: Add minimal device tree support for dra62x also known j5eco. It is related to dm814x, just the clocks are a bit different and it has a different set of integrated devices. And let's get some basic dm814x and dra62x devices working as many of the devices are like on am33xx:: - pinctrl using the pinctrl defines as for am33xx - Updated EDMA bindings with support for using exma_xbar - MMC support for dm814x-evm, t410 and dra62x-j5eco-evm - USB support for dm814x-evm, t410 and dra62x-j5eco-evm This branch depends on an earlier omap-for-v4.5/81xx-fixes-signed branch that has dm814x dts fixes interlaced with SoC related fixes to keep things booting. The interlaced SoC and dts fixes were needed because of issues with the device tree defined clocks that just happened to work on bootloader timings for t410 earlier. * tag 'omap-for-v4.5/81xx-dts-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (21 commits) ARM: dts: Add usb support for j5-eco evm ARM: dts: Add usb support for hp t410 ARM: dts: Add usb support for dm814x-evm ARM: dts: Add usb support for dm814x and dra62x ARM: dts: Enable emmc on hp t410 ARM: dts: Add mmc support for dra62x j5-eco evm ARM: dts: Add mmc support for dm8148-evm ARM: dts: Add mmc device entries for dm814x ARM: dts: Update edma bindings on dm814x to use edma_xbar ARM: dts: Add pinctrl macros for dm814x ARM: dts: Add minimal dra62x j5-eco evm support ARM: dts: Add basic support for dra62x j5-eco SoC ARM: OMAP2+: Remove useless check for legacy booting for dm814x ARM: OMAP2+: Enable GPIO for dm814x ARM: dts: Fix dm814x pinctrl address and mask ARM: dts: Fix dm8148 control modules ranges ARM: OMAP2+: Fix timer entries for dm814x ARM: dts: Fix some mux and divider clocks to get dm814x-evm booting ARM: OMAP2+: Add DPPLS clock manager for dm814x clk: ti: Add few dm814x clock aliases ...
