Subject: [PATCH] clkdev: Add default clkdev.h
Date: Tue, 28 Aug 2012 11:56:53 -0700	[thread overview]
Message-ID: <1346180213-14963-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)

Ease the deployment of clkdev by providing a default asm/clkdev.h for
use if the arch does not have an include/asm/clkdev.h.

Due to limitations in Kbuild we manually add clkdev.h to all
architectures that don't have one rather than having the header appear
by default.
