From 846b38981f8014cc6562f3b89bef4c87cbc8ca2a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Thu, 27 Sep 2012 10:20:33 +0000 Subject: [PATCH] mx5 clocks: Cleanup MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Clean up the i.MX5 clock driver: - Use readl() and writel() instead of their __raw_ counterparts. - Use the clr/setbits_le32() family of macros rather than expanding code. - Use accessor macros for bit-fields instead of _MASK and _OFFSET.
