This patch series aims to add support for Clock/Reset, Real-Time Clock 
and
SDMMC on the RDA Micro RDA8810PL platform.

It also adds Intelligent Flow Controller (IOW, a DMA controller) which 
is
important for working with this MMC IP.

Tested on the Orange Pi 2G-IOT.

Thanks for work! Is it possible to split this patchset logically to 
ease
reviewing and also merging? It currently touches different subsystems 
and has 25
patches.

You could easily split this into different series adding Clock/Reset, 
RTC, IFC,
SDMMC and other misc patches in one series.

Will do. Is it possible for you to test it on your i96 board?
