[PATCH v2 6/7] ARM: mxs: convert stmp378x_devb board to device tree
From: Shawn Guo <hidden>
Date: 2012-07-10 05:39:35
Subsystem:
arm port, the rest · Maintainers:
Russell King, Linus Torvalds
The enc28j60 spi device does not get converted to dts file, because there is no mxs spi driver on mainline so far. The enc28j60 spi in mach-stmp378x_devb.c does not work anyway.
