[PATCH] ARM: BCM5301X: add NAND flash chip description
Hauke Mehrtens
hauke at hauke-m.de
Fri May 29 14:39:47 PDT 2015
This adds the NAND flash chip description for a standard chip found
connected to this SoC. This makes use of generic Broadcom NAND driver
with the iProc interface.
Signed-off-by: Hauke Mehrtens <hauke at hauke-m.de>

changes since RFC:
* remove linux,part-probe, there are still discussion about how
this binding should look like
* always activate the nand driver
* put the description of the nand chip into an own file
* do not remove the IRQ number from the bcma entry
This is based on Broadcom stblinux branch bcm/dts
Florian can you take this.
