Subject: [RFC v5 0/6] dmaengine: Add Synopsys eDMA IP driver (version 0)
Date: Mon, 11 Feb 2019 18:34:29 +0100 [thread overview]
Message-ID: <cover.1549905325.git.gustavo.pimentel@synopsys.com> (raw)
Add Synopsys eDMA IP driver (version 0 and for EP side only) to Linux
kernel. This IP is generally distributed with Synopsys PCIe EndPoint IP
(depends of the use and licensing agreement), which supports:
- legacy and unroll modes
- 16 independent and concurrent channels (8 write + 8 read)
- supports linked list (scatter-gather) transfer
- each linked list descriptor can transfer from 1 byte to 4 Gbytes
- supports cyclic transfer
- PCIe EndPoint glue-logic
This patch series contains:
- eDMA core + eDMA core v0 driver (implements the interface with
DMAengine controller APIs and interfaces with eDMA HW block)
- eDMA PCIe glue-logic reference driver (attaches to Synopsys EP and
provides memory access to eDMA core driver)
Gustavo Pimentel (6):
dmaengine: Add Synopsys eDMA IP core driver
dmaengine: Add Synopsys eDMA IP version 0 support
dmaengine: Add Synopsys eDMA IP version 0 debugfs support
PCI: Add Synopsys endpoint EDDA Device ID
dmaengine: Add Synopsys eDMA IP PCIe glue-logic
