2017-08-28m68k: allow NULL clock for clk_get_rateJonas Gorski
Make the behaviour of clk_get_rate consistent with common clk's clk_get_rate by accepting NULL clocks as parameter. Some device drivers rely on this, and will cause an OOPS otherwise.

2016-09-26m68k: let clk_disable() return immediately if clk is NULLMasahiro Yamada
In many of clk_disable() implementations, it is a no-op for a NULL pointer input, but this is one of the exceptions. Making it treewide consistent will allow clock consumers to call clk_disable() without NULL pointer check.

2014-09-29m68k: move coldfire platform codeGreg Ungerer
Move the m68k ColdFire platform support code directory to be with the existing m68k platforms. Although the ColdFire is not a platform as such, we have always kept all its support together. No reason to change that as this time. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
