[PATCH 0/3] add Atmel EBI (External Bus Interface) DT nodes for AT91SAM9263

[PATCH 0/3] add Atmel EBI (External Bus Interface) DT nodes for AT91SAM9263

[Alexander Stein]

This is based on and requires Boris' work on an EBI driver for AT91. Please
refer to https://lkml.org/lkml/2014/12/3/806.
The reason I added no pinctrl is that those pins from EBI1 in my case are not
muxable. They are fixed so there is nothing I can test here.
I used this patchset and the EBI to configure a PSRAM to be used by the
atmel_lcdfb driver which works so far.
This also means EBI0 is rather untested, but it should behave like EBI1 if
the numbers are correct.

Best regards,
Alexander

Thanks for your patches.
Unless there are other changes in the EBI/SMC bindings (which I'm not
sure since the EBI driver has not been accepted yet) you have my
