Subject: [PATCH v2 09/24] ASoC: rsnd: Add audmacpp clock and reset support for RZ/G3E
Date: Thu, 2 Apr 2026 11:05:08 +0200 [thread overview]
Message-ID: <20260402090524.9137-10-john.madieu.xa@bp.renesas.com> (raw)
In-Reply-To: <20260402090524.9137-1-john.madieu.xa@bp.renesas.com>
RZ/G3E requires additional audmapp clock and reset lines for
Audio DMA-PP operation.
Add global audmacpp clock/reset management in rsnd_dma_probe()
using optional APIs to remain transparent to other platforms.
