From mboxrd@z Thu Jan 1 00:00:00 1970 From: axel.lin@ingics.com (Axel Lin) Date: Wed, 01 May 2013 23:32:05 +0800 Subject: [RFT][PATCH 2/2] clk: wm831x: Fix wm831x_clkout_get_parent In-Reply-To: <1367422261.8160.1.camel@phoenix> References: <1367422261.8160.1.camel@phoenix> Message-ID: <1367422325.8160.2.camel@phoenix> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Current code looks strange because calling wm831x_clkout_set_parent() with 0 as parent parameter, wm831x_clkout_get_parent() will return 1. According to the datasheet: R16528 (4090h) Clock Control1 BIT 0: CLKOUT output source select 0 = FLL output 1 = 32.768kHz oscillator Thus fix the entry order in wm831x_clkout_parents[] to make it has the same meaning as the datasheet and make the return value of wm831x_clkout_get_parent() consistent with the parent pass to wm831x_clkout_set_parent().
