[PATCH v2] arm64: dts: mediatek: mt8192: Mark scp_adsp clock as broken

From: Chen-Yu Tsai
Date: Thu Dec 29 2022 - 05:16:41 EST


The scp_adsp clock controller is under the SCP_ADSP power domain. This
power domain is currently not supported nor defined.

Mark the clock controller as broken for now, to avoid the system from
trying to access it, and causing the CPU or bus to stall.

Fixes: 5d2b897bc6f5 ("arm64: dts: mediatek: Add mt8192 clock controllers")

Changes since v1:
- Changed "broken" to "fail"
- Rebased onto v6.2-rc1 plus v6.2-tmp/* from mediatek repo
