Subject: [PATCH] ASoC: Intel: CNL: Define DPN package for SDW1.
|
|
|
|
As DPN package entries are not defined in the BIOS for SoundWire
|
|
device 1(SDW1), the capability data-port-type can not be mapped
|
|
for SDW1.
|
|
|
|
As a workaround, hard code data-port-type for SDW1.
|
|
Workaround is not required for other devices, since
|
|
BIOS has entry for them.
|
|
|
|
This patch can be reverted once BIOS has entry for SDW1.
|
|
