From 7ce93f3186119754ec7a646bcbeb1f80e4214767 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 25 Nov 2013 14:23:45 -0800 Subject: ARM: OMAP2+: Fix more missing data for omap3.dtsi file After dropping the duplicate data in hwmod that now should come from the .dts files, I noticed few more entries missing. Let's add these as otherwise devices relying on these won't work. Looks like the side tone entries are bundled into the mcbsp1 to 3, so that may needs some special handling in the hwmod code as it's currently trying to look up mcbsp2_sidetone and mcbsp3_sidetone entries.

Reference discussions on forums [1] [2]. Earlier patch solving this on other OMAPs [3]. For OMAP SoCs with this errata, the fix has been to not enable Posted mode. However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode is enabled on reset. So we not only need to ignore enabling of the POSTED bit when the timer is requested, but also disable Posted mode if errata is present.

C4) and Beagle-XM (all revs) need VAUX2 1.8V supply for the USB PHY. As the generic PHY driver can't handle more than one supply at the moment, we configure this supply to be always on. This will cause a very small power impact if the USB host subsystem is not in use, about 76.86 micro-W + LDO power. Older Beagle boards (prior to C4) don't have VAUX2 connected anywhere, so there won't be any functional impact on those boards other than some additional LDO power consumption.
