From b3dba0b81e9612c385c4fb55d546e0104661168d Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Thu, 22 Oct 2009 14:47:42 -0700 Subject: [PATCH] omap1: Fix DSP public peripherals support for ams-delta DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?) machines as long as old dspgateway code were present in the l-o tree. For several months it is no longer included, breaking support for McBSP1 based audio on Amstrad Delta, for example. This patch, derived from the old dspgateway code, corrects the problem for the board by simply taking the DSP out of reset state, I guess. That way, things should not break when a new dsp code is added to the tree, and the change can be reverted then. If there are any reports on McBSP1 or other DSP public peripherals not working for other OMAP1 machines (I've not heard of any for now), I can prepare a more general patch providing an extra include file with a helper function defined.
