Subject: [PATCH 00/10] mfd: ac100: Add support for X-Powers AC100 audio codec / RTC combo IC

Hi everyone,

This series adds support for X-Powers' AC100 audio codec / RTC combo IC.
This chip is found on Allwinner A80 SoC based boards, and is also part
of the AXP813/AXP818 PMIC found with Allwinner A83T SoCs.

The series focuses on the RTC side of the chip. The audio codec will
be done later, once the digital audio interface of the SoC is supported.

Patch 1 adds bulk write support for regmaps without raw formatting.
This is used in the RTC driver to write out the date and time in one
call.

Patch 2 adds device tree bindings for the AC100.

Patch 3 adds the mfd driver for the AC100.

Patch 4 adds the RTC driver for the AC100.

Patch 5 adds RTC clk output support to the RTC driver.
This is a separate patch as the clk code is over 300 LoC. Having a
separate patch should make it easier for the clk maintainers to review.

Patch 6 adds the AC100 device nodes to the A80 Optimus board dts.

Patch 7 adds the AC100 device nodes to the Cubieboard4 board dts.

Patch 8 fixes the order of device nodes in the A80 Optimus board dts.

Patch 9 fixes the order of device nodes in the Cubieboard4 board dts.

Patch 10 changes the fixed osc_32k clk to a fixed factor clk,
representing the 32k clk input pin on the SoC, and also hooks up the
ac100 rtc clk output to this clk in the board dts files.

I'm hoping we can merge the driver bits (patches 2~5) through the
mfd tree, with acks from the rtc and clk maintainers for patches
4 and 5.

Regards
ChenYu
