Subject: [PATCH v3 0/3] Add Mediatek SoC RTC driver 

RTC is one submodule of Mediatek MT6397 PMIC chip[1]. This series
support RTC driver that work with Mediatek SoC like MT8135, MT8173.
It implements second counter and also provide alarm function.

This series base on 4.1-rc1, Test ok on MT8173 platform.

Change in v3:
1. Replace magic number in mt6397-core.c
2. Add comment for some equation and write trigger.
3. Use regmap_bulk_read and regmap_bulk_write to avoid muliple regmap_read
   and regmap_write
4. Replace devm_request_threaded_irq with request_threaded_irq and add
   irq_dispose_mapping
5. Fix Tomasz Figa review comment.

Change in v2:
1. Move RTC address and interrupt to mt6397-core.c, and register
   these resource in mfd_cell.
   http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/323239.html
2. Remove dt-binding document due to register resouce in mfd_cell, not from
   device tree.
3. Update MAINTAINER file to add Mediatek RTC mainainter.
4. Add prefix mtk_ to some internal functions.
5. Fix racy condition
6. Check return value of regmap_read and regmap_write
7. Remove some unnecessary register readback, clear, then write.
8. Add disable alarm in mtk_rtc_set_alarm function
9. Fix Uwe Kleine-König review comment
