Subject: [PATCH v5 0/2] New driver for the Loongson LS2X APB DMA Controller
Date: Wed, 22 Nov 2023 17:27:09 +0800 [thread overview]
Message-ID: <cover.1700644483.git.zhoubinbin@loongson.cn> (raw)
Hi all:
This patchset introduces you to the LS2X apbdma controller.
The Loongson LS2X APB DMA controller is available on Loongson-2K chips.
It is a single-channel, configurable DMA controller IP core based on the
AXI bus, whose main function is to integrate DMA functionality on a chip
dedicated to carrying data between memory and peripherals in APB bus
(e.g. nand).
Thanks.
