From 51c19541624f5588bccb9d4fb3ae518c68c8082e Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Mon, 22 Feb 2010 22:09:26 -0700 Subject: OMAP clock: drop RATE_FIXED clock flag The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it simply causes the omap1_clk_round_rate() function to return the current rate of the clock. omap1_clk_round_rate(), however, should never be called for a fixed-rate clock, since none of these clocks have a .round_rate function pointer set in their struct clk records. Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes the clock code to emit a warning if the OMAP clock maintainer was foolish enough to add a .round_rate function pointer to a fixed-rate clock. "Doctor, it hurts when I pretend that a fixed-rate clock is rate-changeable." "Then don't pretend that a fixed-rate clock is rate-changeable." It has no functional value. This patch drops the RATE_FIXED clock flag, removing it from all clocks that are so marked.
