Subject: Seeking Guidance for New SPI Driver in Mainline Linux Kernel
Date: Fri, 18 Aug 2023 18:40:14 +0530 [thread overview]
Message-ID: <CAHhAz+jdBS3KPCDL2WZ8UBFRhu0hZyHqs0HAdnhamswswF6iug@mail.gmail.com> (raw)
Dear Linux Kernel Community,
I hope this email finds you well.
I am writing to seek your guidance and assistance regarding the
development of a new SPI device driver for our hardware system.
Our hardware, implemented on an FPGA, features an SPI interface that
acts as a Master, offering two distinct modes for data transmission
and reception.
This hardware is connected to the Linux system via the PCIe bus.
This hardware offers two modes for communication: using registers for
debugging purposes and utilizing DMA channels for high-bandwidth
applications. Both modes leverage the PCIe interface for data
exchange.
The hardware boasts several noteworthy features, including support for
multiple speed settings, SPI port switching, configurable sample edge
programming, and adjustable SPI transfer sizes.
As we embark on the task of developing a device driver for this SPI
interface, we intend to follow best practices and leverage existing
resources within the Mainline Linux kernel tree. To achieve this, we
plan to refer to and adapt existing SPI drivers.
We kindly request your recommendations on which existing SPI driver
within the Mainline Linux kernel tree would serve as the most suitable
reference for our endeavor. Your invaluable expertise would greatly
aid us in ensuring the success of this driver development process.
Thank you for your time and consideration. We eagerly anticipate your
guidance and insights.
Warm regards,
Sekhar
