Subject: [PATCH] ASoC: SOF: Intel: initial support for Elkhart Lake
Git-commit: 6173269038e98408c27cfb438ff07d463fbd0b33
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518
Add Kconfig, PCI ID and chip info for EHL platform.
Note that the core mask is different from previous platforms, only
Core0 can be controlled by the host. Additional patches will be
required for multi-core functionality.
