Subject: [PATCHv3 16/35] ARM: OMAP2+: PRM: move SoC specific init calls within a generic API
Date: Wed, 25 Feb 2015 21:04:26 +0200	[thread overview]
Message-ID: <1424891085-10392-17-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1424891085-10392-1-git-send-email-t-kristo@ti.com>

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

Subject: [PATCHv3 16/35] ARM: OMAP2+: PRM: move SoC specific init calls within a generic API
Date: Wed, 25 Feb 2015 21:04:26 +0200	[thread overview]
Message-ID: <1424891085-10392-17-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1424891085-10392-1-git-send-email-t-kristo@ti.com>

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.
