* switch all platform_bus device/driver registering to ↵Jean-Christophe PLAGNIOL-VILLARD2012-10-041-0/+3
| | | | | | | | platform_driver/device_register now register_driver and register_device are for bus only usage. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

| * Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-171-4/+0
| | | | | | | | | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | of: add devicetree probing supportSascha Hauer2012-09-141-0/+10
| | | | | | | | | | | | | | This adds code to probe devices from a devicetree. Most helper functions are directly imported from Linux. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | driver: Add platform_device_id mechanismSascha Hauer2012-09-141-0/+9
| | | | | | | | | | | | | | | | It is common for drivers to handle multiple similar devices. On Linux the driver can distinguish between the devices using the platform_device_id mechanism. Introduce the same for barebox. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | driver: rewrite dev_printf as a functionSascha Hauer2012-09-141-3/+3
|/ | | | | | | | | | Printing device context normally should be "driver instance:", but instead we printed the device name twice. This patch fixes this and as a bonus makes the binary a bit smaller. Instead of a '@' between driver and instance this function now prints a whitespace which is a bit more like Linux. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: set DEVICE_ID_DYNAMIC to -2 and DEVICE_ID_SINGLE to -1Jean-Christophe PLAGNIOL-VILLARD2012-08-121-2/+2
| | | | | | | so we can have the same behaviour as in the kernel for id = -1 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* serial_ns16550: change the driver's nameAntony Pavlov2012-07-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The name "serial_ns16550" is not handy because the devices will have the names like "serial_ns165500", "serial_ns165501", "serial_ns165502" etc. The names like "ns16550_serial0" and "ns16550_serial1" look much better. Also it is reasonable to make serial driver's names unification. E.g. see the names for drivers in drivers/serial directory: "netx_serial", "mpc5xxx_serial", "altera_serial", "s3c_serial", "imx_serial", "pxa_serial", "blackfin_serial", "stm_serial", "pl010_serial", and even "g_serial" in ./drivers/usb/gadget/serial.c Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: fix standard zero, full devicesSascha Hauer2012-07-041-0/+1
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.
