From 3cbd107b5f33364ef3ca286b2ffaffee79f14781 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Thu, 27 Sep 2012 10:23:42 +0000 Subject: mx5 clocks: Simplify imx_get_cspiclk() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code handling the dividers was duplicated for each possible input clock, and this function can benefit from the newly introduced get_standard_pll_sel_clk() function instead of duplicating this mux handling code.
