Subject: [PATCH 0/3]  Enable Multi Core Timer (MCT) for gs101

Hi folks,

This series enables Multi Core Timer (MCT) for gs101. As part of enabling
MCT we also need to register cmu_misc bank of clocks early so exynos_mct can
obtain it's clock.

MCT timer is required longer term as the Arm arch timer can't wake the CPU from
suspend. This series is based off todays linux-next.

Note the dtsi change without the corresponding clock driver changes will result
in a system that doesn't boot. So ideally this would both be merged together
through Krzysztofs Samsung exynos tree. If that is OK with everyone?

regards,

Peter
