Subject: [PATCH 10/13] ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setup
Date: Thu, 25 Oct 2012 17:21:20 -0600	[thread overview]
Message-ID: <20121025232119.17558.41615.stgit@dusk.lan> (raw)
In-Reply-To: <20121025231818.17558.57884.stgit@dusk.lan>

Split omap2_set_globals_prcm() into PRM, CM, and PRCM_MPU variants, since
these are all separate IP blocks.  This should make it easier to move the
PRM, CM, PRCM_MPU code into drivers/ in future patchsets.

At this point arch/arm/plat-omap/include/plat/prcm.h is empty; a
subsequent patch will remove it, and remove the #include from all the
files that #include it.

Subject: [PATCH 10/13] ARM: OMAP2+: PRCM: split and relocate the PRM/CM globals setup
Date: Thu, 25 Oct 2012 17:21:20 -0600	[thread overview]
Message-ID: <20121025232119.17558.41615.stgit@dusk.lan> (raw)
In-Reply-To: <20121025231818.17558.57884.stgit@dusk.lan>

Split omap2_set_globals_prcm() into PRM, CM, and PRCM_MPU variants, since
these are all separate IP blocks.  This should make it easier to move the
PRM, CM, PRCM_MPU code into drivers/ in future patchsets.

At this point arch/arm/plat-omap/include/plat/prcm.h is empty; a
subsequent patch will remove it, and remove the #include from all the
files that #include it.
