Jingoo Han	8074cf063e	spi: use dev_get_platdata() 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>	2013-08-29 13:56:23 +01:00
Jingoo Han	d9740f6aa6	spi: bfin-v3: remove unnecessary platform_set_drvdata() 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>	2013-08-22 10:58:42 +01:00
Julia Lawall	de0fa83c41	spi/spi-{bcm63xx.c,bfin-v3.c}: simplify use of devm_ioremap_resource 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>	2013-08-14 17:47:58 +01:00
Scott Jiang	fa4bd4f1ad	spi: add spi controller v3 master driver for Blackfin 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.
