From mboxrd@z Thu Jan 1 00:00:00 1970 From: Paul Walmsley Subject: [PATCH 15/27] omap2 clock: convert remaining clksel clocks to use omap2_clksel_recalc Date: Mon, 27 Aug 2007 02:39:11 -0600 Message-ID: <20070827084123.566780960@pwsan.com> References: <20070827083856.549249288@pwsan.com> Return-path: Content-Disposition: inline; filename=use_clksel_recalc_for_all_clksel_clks.patch List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-omap-open-source-bounces+gplao-linux-omap-open-source=gmane.org@linux.omap.com Errors-To: linux-omap-open-source-bounces+gplao-linux-omap-open-source=gmane.org@linux.omap.com To: linux-omap-open-source@linux.omap.com List-Id: linux-omap@vger.kernel.org This completes the transition to struct clksel/clksel_rate by converting the remaining clksel clocks to call omap2_clksel_recalc() on rate recalculation. Also remove RATE_FIXED from some clocks that can now recalculate their own rates correctly via clksel.
