Subject: [PATCH 04/17] ARM: MXS: Add MXS specific clk types
Date: Thu, 20 Jun 2013 08:54:08 +0200	[thread overview]
Message-ID: <1371711261-10039-5-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1371711261-10039-1-git-send-email-s.hauer@pengutronix.de>

MXS needs some special MXS specific clock types:

- pll
- ref (fractional divider)
- busy divider (divider with additional busy bit to poll on a rate change)
- lcdif (Combined clock out of a fractional divider, a divider and a gate.
