Subject: [PATCH 1/7] soundwire: bus: use property to set interrupt masks
Date: Tue, 18 Aug 2020 22:06:50 +0800 [thread overview]
Message-ID: <20200818140656.29014-2-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20200818140656.29014-1-yung-chuan.liao@linux.intel.com>
From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
Add a slave-level property and program the SCP_INT1_MASK as desired by
the codec driver. Since there is no DisCo property this has to be an
implementation-specific firmware property or hard-coded in the driver.
The only functionality change is that implementation-defined
interrupts are no longer set for amplifiers - those interrupts are
typically for jack detection or acoustic event detection/hotwording.
