From 819c1de344c5b8350bffd35be9a0fa74541292d3 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Mon, 29 Jul 2013 12:25:01 +0100 Subject: clk: add CLK_SET_RATE_NO_REPARENT flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes being reparented during clk_set_rate. To avoid breaking existing platforms, all callers of clk_register_mux() are adjusted to pass the new flag. Platform maintainers are encouraged to remove the flag if they wish to allow mux reparenting on set_rate.
