This patch removes restart hook from machine_desc of Exynos, and moves respective code into reboot_notifiers. Exynos5440 handles reboot via clock register so let's register a reboot_notifier in Exynos5440 clock driver. For reset Exynos SoC, reboot is handled via PMU SWRESET register so let's register a reboot_notifier in PMU driver for handling this. This patch is inspired and dependent on following patch series[1] from Geunter Roeck. Also this patch is dependent on PMU platform driver patch [2] by me, and has been prepared on top of it. [1]: kernel: Add support for kernel restart handler call chain https://lkml.org/lkml/2014/8/19/652 [2]: ARM: Exynos: Convert PMU implementation into a platform driver https://lkml.org/lkml/2014/9/30/219 I have tested reboot functionality on Exynos3250 based board, on kgene/for-next as well as linux-next's next-20140925 tag. Patch v1 and related discussion can be found here http://www.spinics.net/lists/linux-samsung-soc/msg37445.html Changes since v1: - Addressed review comments from Tomasz Figa. Removed usage of local variables where ever unnecessary. - Make reg_base as global in clk-exynos5440.c file, to avoid iomapping it again in reboot_notifier handler.
