Hi,

This series enables the SPI NAND found on the Avaota A1 in Quad SPI
mode. The SPI driver already supports Dual SPI and Quad SPI, but the
bindings need to be updated to allow it.

Patch 1 updates the binding to allow Dual SPI and Quad SPI on the newer
SoCs. It also allows describing no TX or no RX available.

Patch 2 adds another set of pins for spi0 on the A523 SoC family. This
set is used for the SPI NAND on the Avaota A1 board.

Patch 3 enables the SPI NAND found on the board. No partition layout
is provided at the moment.


Please have a look.


Thanks
ChenYu
