[6..11]: IDA-based system-unique Device Number to be used for wake-capable devices such as jack codecs or microphone codecs. These values were chosen based on the typical maximum number of devices per link given electrical/PHY limitations. This configuration will e.g. allow for 8 amplifiers on 2 links, and additional devices on the remaining links. Example on Dell SDCA device with jack codec, two amplifiers and one microphone codec: only the jack codec relies on the IDA, others use the same Device Number 1 on separate links. rt711-sdca sdw:0:025d:0711:01: signaling enumeration completion for Slave 6 rt1316-sdca sdw:1:025d:1316:01: signaling enumeration completion for Slave 1 rt1316-sdca sdw:2:025d:1316:01: signaling enumeration completion for Slave 1 rt715-sdca sdw:3:025d:0714:01: signaling enumeration completion for Slave 1 Signed-off-by: Pierre-Louis Bossart Reviewed-by: Rander Wang Signed-off-by: Bard Liao --- drivers/soundwire/intel_auxdevice.c | 23 +++++++++++++++++++---- 1 file changed, 19 insertions(+), 4 deletions(-) diff --git a/drivers/soundwire/intel_auxdevice.c b/drivers/soundwire/intel_auxdevice.c index c1df6f014e6b..917edc75ddfb 100644 --- a/drivers/soundwire/intel_auxdevice.c +++ b/drivers/soundwire/intel_auxdevice.c @@ -23,8 +23,12 @@ #include "intel.h" #include "intel_auxdevice.h" -/* IDA min selected to avoid conflicts with HDaudio/iDISP SDI values */ -#define INTEL_DEV_NUM_IDA_MIN 4 +/* + * IDA min selected to allow for 5 unconstrained devices per link, + * and 6 system-unique Device Numbers for wake-capable devices. + */ + +#define INTEL_DEV_NUM_IDA_MIN 6 #define INTEL_MASTER_SUSPEND_DELAY_MS 3000 @@ -66,9 +70,20 @@ static void generic_new_peripheral_assigned(struct sdw_bus *bus, { struct sdw_cdns *cdns = bus_to_cdns(bus); struct sdw_intel *sdw = cdns_to_intel(cdns); + int min_dev = 1; + int max_dev = SDW_MAX_DEVICES; + + if (bus->dev_num_alloc == SDW_DEV_NUM_ALLOC_IDA) { + min_dev = INTEL_DEV_NUM_IDA_MIN; + } else if (bus->dev_num_alloc == SDW_DEV_NUM_ALLOC_IDA_WAKE_ONLY) { + if (slave->prop.wake_capable) + min_dev = INTEL_DEV_NUM_IDA_MIN; + else + max_dev = INTEL_DEV_NUM_IDA_MIN - 1; + } /* paranoia check, this should never happen */ - if (dev_num < INTEL_DEV_NUM_IDA_MIN || dev_num > SDW_MAX_DEVICES) { + if (dev_num < min_dev || dev_num > max_dev) { dev_err(bus->dev, "%s: invalid dev_num %d\n", __func__, dev_num); return; } @@ -167,7 +182,7 @@ static int intel_link_probe(struct auxiliary_device *auxdev, cdns->msg_count = 0; bus->link_id = auxdev->id; - bus->dev_num_alloc = SDW_DEV_NUM_ALLOC_IDA; + bus->dev_num_alloc = SDW_DEV_NUM_ALLOC_IDA_WAKE_ONLY; bus->dev_num_ida_min = INTEL_DEV_NUM_IDA_MIN; bus->clk_stop_timeout = 1;
