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
