From f32bd7787561ceb887e45d81ca41d6c7a903751f Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 8 May 2012 11:34:28 -0600 Subject: ARM: OMAP2xxx: hwmod data: add HDQ/1-wire hwmod Add the HDQ1W hwmod for all OMAP2xxx devices. Assume that OMAP2xxx chips have the same HDQ idle handling bug as OMAP3: http://www.spinics.net/lists/linux-omap/msg63576.html and set the OCPIF_SWSUP_IDLE flag accordingly on the HDQ's OCP interface.
