[PATCH kernel-4.19 2/3] ALSA: hda: Add support of Zhaoxin NB HDAC
Add the new PCI ID 0x1d17 0x9141/0x9142/0x9144 Zhaoxin NB HDAC support. And add some special initialization for Zhaoxin NB HDAC. The patch is scheduled to be submitted to the kernel mainline in 2021.

Add the new PCI ID 0x1d17 0x9141/0x9142/0x9144 Zhaoxin NB HDAC support. And add some special initialization for Zhaoxin NB HDAC.
The patch is scheduled to be submitted to the kernel mainline in 2021.

Then chip->driver_caps & AZX_DCAPS_CTX_WORKAROUND will run extra azx_rirb_zxdelay() as well, does it have side effect?
No. azx_rirb_azdelay() only apply to Zhaoxin NB HDAC controller actually.
OK, I can see remap_diu_addr is introduced for this purpose, not good enough, but we can keep this as it is. Reviewed-by: Hanjun Guo <guohanjun@huawei.com> Thanks Hanjun
