Subject: [PATCH 0/2] dmaengine: at_xdmac: retrieve DMA channels from device tree
Date: Wed, 5 Feb 2025 11:17:01 +0530 [thread overview]
Message-ID: <20250205-mchp-dma-v1-0-124b639d5afe@microchip.com> (raw)
This patch series adds support to get the number of DMA channels available in
XDMAC from dts. This property is required when the channel count cannot be read
from the XDMAC_GTYPE register (which occurs when accessing from non-secure
world on certain devices)
