Hi all,

This patch series aims to add DM support for the AEMIF controller that
can be found in the DaVinci SoCs.

This controller has already a driver used by the Keystone SoCs so I
add my work to it.

As we can now easily import Linux device-trees, I try to stick the
most I can to the Linux bindings of the AEMIF controller. To do so I add
an 'intermediate' driver called 'ti-aemif-cs'. It's in charge of
configuring timings for a given chip select of the AEMIF controller.

Bastien Curutchet (6):
  memory: ti-aemif: Correct macro to ensure avoiding precedence issues
  memory: ti-aemif: Make AEMIF driver architecture agnostic
  memory: ti-aemif: Add ARCH_DAVINCI to architectures that uses TI_AEMIF
  memory: ti-aemif: Wrap the CS configuration into a function
  memory: ti-aemif: Add DM support
  memory: ti-aemif-cs: Compute timing configuration from DT parsing

Applied to u-boot/master, thanks!
