* treewide: remove address of the Free Software FoundationAntony Pavlov2014-06-112-9/+0
| | | | | | | | | | | | | | | | | | The FSF address has changed; The FSF site says that address is Free Software Foundation 51 Franklin Street, Fifth Floor Boston, MA 02110-1301 USA (see http://www.fsf.org/about/contact/) Instead of updating it each time the address changes, just drop it completely treewide.

| | | | | | | | | | | | | | | | | | | | The omap3 and omap4/am33xx spi cores differ in the offset of the registers in the address space. Instead of encoding this into the resources use the platform_device_id mechanism. This is done in preparation for devicetree probe support where the address space is in the devicetree and can't be adjusted. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.

| |/ | | | | | | | | | | | | | | | | | | | | This creates a Linux OF API compatible counterpart of of_get_named_gpio_flags. Existing of_get_named_gpio is converted to a static inline function, which is in the corresponding of_gpio.h include. While at it, drivers/of/gpio.c is also renamed to drivers/of/of_gpio.c to follow the of_ prefix naming scheme. The new include is also added to existing users of of_get_named_gpio.
