Subject: [PATCHv2 0/2] spi: orion: Add multiple chip select support to spi-orion

Hello,      

This patch series adds multiple chip select support for the spi-orion driver.
The first patch moves spi-orion to use the spi setup/set_cs/transfer_one         
function pointers, which reduces duplicated code, and simplifies the chip 
select support implementation.

The second patch adds support for multiple chip selects. Currently
there is no additional support for gpio chip selects, as I do not 
have a board to test that with. 

These patches have been tested on an Armada 375 with 2 SPI-NOR chips.

Thanks,
Ken
