[PATCH v2 10/13] ARM: davinci: da830-evm: use aemif platform driver

From: Bartosz Golaszewski
Date: Tue Jun 26 2018 - 05:27:14 EST


From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

We now support board files in the aemif driver. Register a platform
device instead of using the handcrafted API in da830-evm.
