This patchset adds platform_data for spi-altera, to enable more IP configurations, and creating specific spi client devices. It also adds regmap support, to enable the indirect access to this IP. We have a PCIE based FPGA platform which integrates this IP to communicate with a BMC chip (Intel MAX10) over SPI. The IP is configured as 32bit data width. There is also an indirect access interface in FPGA for host to access the registers of this IP. This patchset enables this use case. Matthew Gerlach (1): spi: altera: fix size mismatch on 64 bit processors Xu Yilun (5): spi: altera: add 32bit data width transfer support. spi: altera: add SPI core parameters support via platform data. spi: altera: add platform data for slave information. spi: altera: use regmap instead of direct mmio register access spi: altera: move driver name string to header file drivers/spi/Kconfig | 1 + drivers/spi/spi-altera.c | 161 +++++++++++++++++++++++++++++++++++++-------- include/linux/spi/altera.h | 37 +++++++++++ 3 files changed, 171 insertions(+), 28 deletions(-) create mode 100644 include/linux/spi/altera.h -- 2.7.4
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
