Subject: [PATCH 0/3] Enable Multi Core Timer (MCT) for gs101
Date: Fri, 22 Dec 2023 16:53:52 +0000 [thread overview]
Message-ID: <20231222165355.1462740-1-peter.griffin@linaro.org> (raw)
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
