[PATCH v3 3/3] ASoC: sunxi: sun4i-spdif: Reorder clock enable sequence
From: phucduc . bui
Date: Tue Jun 02 2026 - 07:51:31 EST
From: bui duc phuc <phucduc.bui@xxxxxxxxx>
Reorder the runtime resume clock enable sequence to match the hardware
dependency and ensure symmetry with the suspend path.
The APB bus clock drives the register interface and must be enabled before
the functional module clock. This aligns the resume sequence to be the
exact reverse of the suspend sequence.

NOTE: This patch is compile-tested only.
Changes in v3:
- Clarify in the commit message that the resume sequence becomes the
reverse of the suspend sequence.
