Subject: [PATCH 2/3] ASoC: SOF: Intel: hda-loader: Make sure that the fw load sequence is followed
Date: Thu,  9 Jun 2022 11:59:48 +0300	[thread overview]
Message-ID: <20220609085949.29062-3-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20220609085949.29062-1-peter.ujfalusi@linux.intel.com>

The hda_dsp_enable_core() is powering up _and_ unstall the core in one
call while the first step of the firmware loading  must not unstall the
core.
The core can be unstalled only after the set cpb_cfp and the configuration
of the IPC register for the ROM_CONTROL message.
