Subject: [PATCH 12/28] omap2 clock: stop using clk->src_offset in omap2_clk_set_rate()
Date: Mon, 20 Aug 2007 03:53:59 -0600 [thread overview]
Message-ID: <20070820095531.141524497@pwsan.com> (raw)
In-Reply-To: 20070820095347.933473149@pwsan.com
[-- Attachment #1: convert_set_rate.patch --]
[-- Type: text/plain, Size: 1472 bytes --]
Stop using clk->rate_offset in omap2_clk_set_rate(); use what we get
from the clksel code instead.
