2015-10-28spi: Drop owner assignment from spi_driversAndrew F. Davis1-1/+0
An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-09-09Lattice ECP3 FPGA: Check firmware pointerJean-Michel Hautbois1-0/+5
This patch corrects a lack of testing. If fw is NULL when calling firmware_load(), it results in a kernel oops. Signed-off-by: Jean-Michel Hautbois <jean-michel.hautbois@vodalys.com> Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-07-27Lattice ECP3 FPGA: Correct endiannessJean-Michel Hautbois1-7/+9
This code corrects endianness and avoids a sparse error. Tested with Lattice ECP3-35 with Freescale i.MX6. It also sends uevent in order to load it. Signed-off-by: Jean-Michel Hautbois <jean-michel.hautbois@vodalys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-02-08drivers/misc: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

Correct spelling typo in various part of drivers Signed-off-by: Masanari Iida <standby24x7@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2013-04-06misc: lattice-ecp3-config: use spi_get_drvdata()Jingoo Han1-1/+1
Use the wrapper functions for getting and setting the driver data using spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we can directly pass a struct spi_device. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-17misc: lattice-ecp3-config.c: remove __dev* markingsGreg Kroah-Hartman1-4/+4
These are now removed from the kernel, so remove them to allow the driver to build properly. Cc: Stefan Roese <sr@denx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-17misc: Add Lattice ECP3 FPGA configuration via SPIStefan Roese1-0/+243
This patch adds support for bitstream configuration (programming / loading) of the Lattice ECP3 FPGA's via the SPI bus. Here an example on my custom MPC5200 based board: $ echo 1 > /sys/class/firmware/spi0.0/loading $ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data $ echo 0 > /sys/class/firmware/spi0.0/loading leads to these messages: lattice-ecp3 spi0.0: FPGA Lattice ECP3-35 detected lattice-ecp3 spi0.0: Configuring the FPGA... lattice-ecp3 spi0.0: FPGA succesfully configured!
