Merge tag 'samsung-dt-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup3
Merge "Samsung 2nd DT updates for v3.15" from Kukjin Kim: - add DT entry for AHCI SATA and SATA PHY with using generic PHY framework for exynos5250 and arndale, smdk5250 boards. - add SSS DT node for exynos5420 and exynos5250 - remove leftover spi0 node for smdk5250 board - add ADC and thermistor nodes for exynos4412-trats2 board - move common irq-combiner node for exynos4x12 from exynos4212 and exynos4412 - add ADC, PMU and GPS_ALIVE power domain nodes for exynos4x12 Note that based on previous tags/samsung-dt and tags/exynos-clk * tag 'samsung-dt-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung: ARM: dts: enable ahci sata and sata phy for exynos5250 ARM: dts: add dt node for sss module for exynos5250/5420 ARM: dts: Remove leftover spi0 node for smdk5250 ARM: dts: Add ADC and themistor nodes for exynos4412-trats2 ARM: dts: Move common dt data for interrupt combiner controller for exynos4x12 ARM: dts: Add GPS_ALIVE power domain for exynos4x12 ARM: dts: Add PMU dt data to support PMU for exynos4x12 ARM: dts: Add ADC's dt data to read raw data for exynos4x12 Signed-off-by: Arnd Bergmann <arnd@arndb.de>
