[PATCH] ASoC: sh: fsi-ak4642: Add FSI port and ak464x selection

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Current FSI-Ak4642 device had niche settings which were
FSI2-A-AK4643 and FSI-A-AK4642.
This patch add platform_device_id which can control
FSI/FSI2, PortA/PortB, AK4642/AK4643 from platform data.
