Samsung DTS ARM changes for v5.2 1. Use proper ADC on Exynos4412. 2. Extend the Exynos5420 Arndale Octa board with: CPU cooling maps, unused regulators, ADC and UHS-I SD card support. Beside that adjust regulators to proper level and add always-on when needed. 3. Extend the Exynos5260: high speed I2C and proper external interrupts. Also fix shared external interrupt line and use better PLL for MMC clocks. 4. Fix audio recording (broken around v5.1) and microphone recording (since v4.14) on Exynos5422 Odroid XU3 boards. 5. Minor cleanups (stdout-path and bootargs).
