* dma: keystone_nav: generalize driver usageKhoronzhuk, Ivan2014-10-23-89/+98
| | | | | | | | | | | | | | | | | | | The keystone_nav driver is general driver intended to be used for working with queue manager and pktdma for different IPs like NETCP, AIF, FFTC, etc. So the it's API shouldn't be named like it works only with one of them, it should be general names. The names with prefix like netcp_* rather do for drivers/net/keystone_net.c driver. So it's good to generalize this driver to be used for different IP's and delete confusion with real NETCP driver. The current netcp_* functions of keystone navigator can be used for other settings of pktdma, not only for NETCP. The API of this driver is used by the keystone_net driver to work with NETCP, so net driver also should be corrected. For convenience collect pkdma configurations in drivers/dma/keystone_nav_cfg.c.

* dma: keystone_nav: move keystone_nav driver to driver/dma/Khoronzhuk, Ivan2014-10-23-29/+59
| | | | | | | | | | | | | | The keystone_nav is used by drivers/net/keystone_net.c driver to send and receive packets, but currently it's placed at keystone arch sources. So it should be in the drivers directory also. It's separate driver that can be used for sending and receiving pktdma packets by others drivers also. This patch just move this driver to appropriate directory and doesn't add any functional changes.

| * dm: serial: Tidy up the pl01x driverSimon Glass2014-10-22-140/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adjust the driver so that leaf functions take a pointer to the serial port register base. Put all the global configuration in the init function, and use the same settings from then on. This makes it much easier to move to driver model without duplicating the code, since with driver model we use platform data rather than global settings. The driver is compiled with either the CONFIG_PL010_SERIAL or CONFIG_PL011_SERIAL option and this determines the uart type. With driver model this needs to come in from platform data, so create a new CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the driver to support both peripheral variants.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use gpio_request for all the gpios that are utilized by various subsystems in cm-fx6, and refactor the relevant init functions so that all gpios are requested during board_init(), not during subsystem init, thus avoiding the need to manage gpio ownership each time a subsystem is initialized. The new division of labor is: During board_init() muxes are setup and gpios are requested. During subsystem init gpios are toggled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want the SPI flash probing feature to operate as a standard driver. Add a driver for the basic probing feature used by most boards. This will be activated by device_probe() as with any other driver. The 'sf probe' command currently keeps track of the SPI slave that it last used. This doesn't work with driver model, since some other driver or system may have probed the device and have access to it too. On the other hand, if we try to probe a device twice the second probe is a nop with driver model. Fix this by searching for the matching device, removing it, and then probing it again. This should work as expected regardless of other device activity. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
