The new CPU clock type allows the use of generic CPUfreq driver. Switch Exynos4x12 to using generic cpufreq driver. Previously (when exynos-cpufreq driver was used with boost functionality) ARM_EXYNOS_CPU_FREQ_BOOST_SW config option (which enabled boost functionality) selected EXYNOS_THERMAL one. After switching Exynos4x12 platforms to use cpufreq-dt driver boost support is enabled in the cpufreq-dt driver itself (because there are turbo OPPs defined in the board's DTS file). However we still would like to allow enabling boost support only if thermal support is also enabled for Exynos platforms. To achieve this make ARCH_EXYNOS config option select THERMAL and EXYNOS_THERMAL ones. Please also note that the switch to use the generic cpufreq-dt driver fixes the minor issue present with the old code (support for 'boost' mode in the exynos-cpufreq driver was enabled for all supported SoCs even though 'boost' frequency was provided only for Exynos4x12 ones).

The odroid-xu3 board which is based on exynos5422 not exynos5800 is booted from cortex-a7 core unlike exynos5800. The odroid-xu3's cpu order is quite strange. cpu0 and cpu5-7 are cortex-a7 cores and cpu1-4 are cortex-a15 cores. To correct this mis-odering, I added exynos5422-cpus.dtsi and reversing cpu orders from exynos5420. Now, cpu0-3 are cortex-a7 and cpu4-7 are cortex-a15. Reviewed-by:

Exynos4x12 based platforms have switched over to use generic cpufreq driver for cpufreq functionality. So the Exynos specific cpufreq support for these platforms can be removed. Also once Exynos4x12 based platforms support have been removed the shared exynos-cpufreq driver is no longer needed and can be deleted. Based on the earlier work by Thomas Abraham.

The Exynos5420 based Peach Pit and Exynos5800 based Peach Pi Chromebooks use the Maxim max77802 Power Management IC (PMIC). This PMIC has besides other devices, a set of regulators that can be controller over I2C. Commit f3caa529 ("ARM: multi_v7_defconfig: Enable max77802 regulator, rtc and clock drivers") was supposed to enable the config option for the regulator driver as a module but the final version that landed did not include this. The commit was modified and the REGULATOR_MAX77802 removed since it was thought to be useless. Unfortunately that's not the case for the mentioned reason above so this patch enables the needed Kconfig option. Signed-off-by:

In order for the Arria10 to be able to re-use the reset driver for SoCFPGA Cyclone5/Arria5, we need to read the 'altr,modrst-offset' property from the device tree entry. The 'altr,modrst-offset' property is the first register into the reset manager that is used for bringing peripherals out of reset. The driver assumes a modrst-offset of 0x10 in order to support legacy Cyclone5/Arria5 hardware. Signed-off-by:Dinh Nguyen <dinguyen@opensource.altera.com>

This reset controller features up to 64 reset lines connected to different blocks and peripheral in the SoC. Most reset lines on the controller are self clearing except for those dealing with the Cortex-M0 cores on LPC43xx devices. This driver also registers a restart handler that can be used to reset the entire device. Signed-off-by:
