Subject[PATCH 14/21] ASoC: SOF: mediatek: Add mt8195 hardware support
Date
From: YC Hung <yc.hung@mediatek.com>

This patch initialize to support SOF on Mediatek mt8195 platform.
MT8195 has four Cortex A78 cores paired with four Cortex A55 cores.
It also has Cadence HiFi-4 DSP single core. There are shared DRAM and
mailbox interrupt between AP and DSP to use for IPC communication.
