Subject: ARM: OMAP4: hwmod data: add GPMC
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eb42b5d3997c3a7d0da6c3bb56c1a0055ba3b2be;p=linux-beck.git

ARM: OMAP4: hwmod data: add GPMC

Add the GPMC hwmod and associated interconnect data.   The GPMC is a
programmable parallel-bus memory controller.
