Re: [PATCH v3 04/19] clk: at91: add PMC macro file for dt definitions

From: Nicolas Ferre
Date: Mon Oct 07 2013 - 11:18:06 EST


On 08/08/2013 07:04, Boris BREZILLON :
This patch adds a new macro file for PMC macros.

This macro file includes the definitions of SR (status register) bit
offsets and will be use to reference PMC irqs.
