Subject: ARM: OMAP2+: PRM: provide generic API for system reset
X-Git-Tag: omap-for-v3.19/prcm-cleanup^0
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=61c8621e2bd14faad9b89ab2284955b28000bcd5;p=pandora-kernel.git

ARM: OMAP2+: PRM: provide generic API for system reset

This patch combines the various prm_warm_reset calls under a common
API prm_reset_system, and adds the SoC specific implementation under
prm_ll_data.
