[rtc-linux] [PATCH v4 0/6] SA1100/PXA RTC clean-up

[Rob Herring <robh@kernel.org>]

This series enables building the SA1100 RTC driver for ARM64 in
preparation for enabling CONFIG_ARCH_MMP on ARM64. This is needed for
supporting the PXA1928 SOC. Clean-up of SA1100 RTC is complicated by the
fact that some PXA chips use both sa1100-rtc and pxa-rtc drivers and
share the same registers. This does not work well with the Linux driver
model. So the first step is removing this sharing by the 2 drivers and
making sa1100-rtc and pxa-rtc mutually exclusive.

The previous versions can be found here[1][2][3]. Patches 1 and 2 are new.
Patches 3, 5, and 6 are unchanged. Patch 4 is mostly the same, but
adjusted due to patches 1 and 2.

A git branch is here[4]. I've tested sa1100-rtc on PXA1928. I need help
testing on PXA27x/3xx.
