[linux dev-4.13 0/6] SMC driver updates

[Cédric Le Goater]

Hello,

Here is a series bringing the Aspeed SMC driver to the level of what
we had in openbmc kernel 4.10. There are a couple of changes :

 - the DMA support is gone. It is not used, it only works for
   kmalloc'ed buffers and UBIFS uses vmalloc'ed buffers for instance.

 - the driver was slightly adapted to take into account the new clk
   driver.

Tested on a palmetto and an ast2500 eval boards.

Thanks,

C.
