Merge tag 'gemini-v4.13-dts-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt
This is a first set of Gemini DTS patches for the v4.13 cycle. This adds the reset and clock lines to the Gemini core DTS SoC. These bindings have been ACKed by the DT maintainer Rob. The reset driver is going to be merged by the reset maintainer. The clock driver is going to be merged by the clock maintainers. Each of these have their macro defines coming with them, split off as separate patches. A post-rc1 patch will be sumbitted for switching the numerical values to the defined macros in line with the ARM SoC DT header merge strategy. * tag 'gemini-v4.13-dts-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: ARM: dts: Add clocks to the Gemini SoC ARM: dts: Add the Gemini reset controller dt-bindings: Augment Gemini for clocks, resets Signed-off-by: Olof Johansson <olof@lixom.net>
