Subject: [PATCH V4 0/4] Add i.MX system controller RTC driver
Date: Thu, 29 Nov 2018 01:49:57 +0000 [thread overview]
Message-ID: <1543455856-18021-1-git-send-email-Anson.Huang@nxp.com> (raw)
NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as
system controller, the system controller is in charge of system
power, clock and secure RTC etc. management, Linux kernel
has to communicate with system controller via MU (message unit)
IPC to do RTC operation.
Since the RTC set time MUST to be done in secure EL3 mode (required
by system controller firmware) and ALARM functions needs to be done
with general MU IRQ handle, these are NOT ready NOW, so this patch
ONLY supports RTC read time for now.
Note that this patch set is based on [V4,5/5] defconfig: arm64: add imx8qxp support,
https://patchwork.kernel.org/patch/10677315/
