* spi: convert spi-bfin-v3.c to a multiplatform driverScott Jiang2014-04-141-965/+0
| | | | | | | | Spi v3 controller is not only used on Blackfin. So rename it and use ioread/iowrite api to make it work on other platform. Signed-off-by: Scott Jiang <scott.jiang.linux@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>

| | | | | | | | | | | | | | | | Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>

| * spi/spi-{bcm63xx.c,bfin-v3.c}: simplify use of devm_ioremap_resourceJulia Lawall2013-08-141-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. Move the call to platform_get_resource adjacent to the call to devm_ioremap_resource to make the connection between them more clear. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@linaro.org>
* | spi: bfin-v3: remove unnecessary platform_set_drvdata()Jingoo Han2013-08-221-2/+0
|/ | | | | | | | | The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
* spi: add spi controller v3 master driver for BlackfinScott Jiang2013-07-151-0/+973
New spi controller(version 3) is integrated into Blackfin 60x processor. Comparing to bf5xx spi controller, we support 32 bits word size and independent receive and transmit DMA channels now. Also mode 0 and 2 (CPHA = 0) can get fully supported becasue cs line may be controlled by the software.
