Subject: [PATCH v2 00/15] dmaengine: dw-edma: HDMA support
Date: Tue, 2 Feb 2021 13:40:14 +0100 [thread overview]
Message-ID: <cover.1612269536.git.gustavo.pimentel@synopsys.com> (raw)
This patch series adds the HDMA support, as long the IP design has set
the compatible register map parameter, which allows compatibility at
some degree for the existing Synopsys DesignWare eDMA driver that is
already available on the Kernel.
The HDMA "Hyper-DMA" IP is an enhancement of the eDMA "embedded-DMA" IP.
This new improvement comes with a PCI DVSEC that allows to the driver
recognize and switch behavior if it's an eDMA or an HDMA, becoming
retrocompatible, in the absence of this DVSEC, the driver will assume
that is an eDMA IP.
It also adds the interleaved support, since it will be similar to the
current scatter-gather implementation.
As well fixes/improves some abnormal behaviors not detected before, such as:
- crash on loading/unloading driver
- memory space definition for the data area and for the linked list space
- scatter-gather address calculation on 32 bits platforms
- minor comment and variable reordering
Change log:
From V1 to V2
- Applied changes based on Bjorn Helgaas' review
- Rebased patches on top of v5.11-rc1 version
