Subject: [PATCH 00/17] Basical Allwinner R329 support

This patchset tries to add basical support for Allwinner R329 SoC to the
Linux kernel, including clock/pintrl driver and MMC support.

Three patches from the H616 patchset, which are used to support the RTC
with linear day, are attached into this patchset. Other RTC-related
patches of that patchset is not included, because the binding of the
clock part there is still under discussion.

Then I added RTC binding and support (which is now only a struct
addition). I added RTC into this patchset, with the same reason that
H616 patchset contains RTC, which is to make the clock tree correct at
the first inclusion.

After RTC, main basical SoC-specific part, pinctrl and CCU, come. The
R329 CCU is something special because PLLs are in R-CCU, no main CCU.

MMC support is added here because it's also a simple struct addition
work, no main driver code change needed.

Finally it comes the DT part. The DT binding of MaixSense, the device
that I am working on now, is added. Then the DTSI for R329 SoC, the DTSI
file for Sipeed Maix IIA SoM (which is utilized on MaixSense) and the
main DT file for MaixSense are added.
