Currently Exynos cpufreq drivers rely on globally mapped clock controller registers to configure frequency of CPU cores. This is obviously wrong and will be removed in near future, but to enable support for multi-platform builds without introducing a regression it needs to be worked around. This patch hacks the code to look for clock controller node in device tree and map its registers using of_iomap(), instead of relying on global mapping, so dependencies on platform headers are removed and the driver can compile again with multiplatform support.

The keystone SoC can be rebooted in several ways. By external reset pin, by soft and by watchdogs. To allow keystone SoC reset if watchdog is triggered we have to enable it in reset mux configuration register regarding of watchdog configuration. Also we need to set soft/hard reset we are going to use. So add keystone reset driver to handle all this stuff. Reviewed-by:

This node is intended to allow SoC reset in case of software reset or appropriate watchdogs. The Keystone SoCs can contain up to 4 watchdog timers to reset SoC. Each watchdog timer event input is connected to the Reset Mux block. The Reset Mux block can be configured to cause reset or not. Additionally soft or hard reset can be configured. Reviewed-by:

A look at the code reveals use of S5P_VA_SYSRAM macro, in case of certain SoC revisions, which is not valid any longer, after SYSRAM started to be mapped dynamically. The new dynamic mapping is stored in sysram_base_addr variable, which is declared static in platsmp.c This fix makes sysram_base_addr non-static, declared it in common.h and used in pm.c instead of S5P_VA_SYSRAM.

There is no point to register the cpuidle driver for the 5440 as it has only one WFI state which is the default idle function when the cpuidle driver is disabled. By disabling cpuidle we prevent to enter to the governor computation for nothing, thus saving a lot of processing time. The only drawback is the statistic via sysfs on this state which is lost but it is meaningless and it could be retrieved from the ftrace easily. Signed-off-by:
