From dcf3d458304aafda3d12413ade39fdf19740dbc3 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik <robert.jarzmik@free.fr> Date: Tue, 7 Oct 2014 01:07:57 +0200 Subject: [PATCH] clk: pxa: fix pxa27x CCCR bit usage Trivial fix to check the A bit of CCCR for memory frequency calculations, where the shift of the bit index was missing, triggering a wrong calculation of memory frequency.
