Subject: [RFC PATCH 00/10] Add support for DMA and audio codec of F1C100s

This is RFC patchset for Allwinner suniv F1C100s to support DMA and
audio codec.

Allwinner F1C100s has a audio codec that has necessary digital and
analog parts. It has r-l headphone output and microphone, line, r-l
FM inputs. ADC can capture any inputs and also output channels via mux.
Any input channels or DAC samples can feed output channels. 

Add support for this audio codec.

F1C100s utilizes DMA channels to send and receive ADC-DAC samples. So
DMA support needed. Patch 1~5 adds support for DMA. Suniv F1C100s has 
very similar DMA to sun4i. But there is some dissimilarities also. 
Suniv features a DMA reset bit in clock  control unit. It has smaller 
number of DMA channels. Several registers has different addresses. 
It's max burst size is 4 instead of 8. Also DMA endpoint numbers are 
different.

Patch 6 adds DMA max burst option to sun4i-codec.

Patch 7~8 Add support for suniv F1C100s audio codec.

Patch 9 adds audio codec to suniv-f1c100s.dtsi

Patch 10 adds audio codec support to Lichee Pi Nano board.

Thanks!
