* devfs: Drop dev_lseek_default()Andrey Smirnov2019-01-291-1/+0
| | | | | | | | | | | | | | | | | | | | | Only the following cdevs do not declare an .lseek() operation: - Console devices in common/console.c - Firmware framework in common/firmware.c - JTAG driver in drivers/misc/jtag.c - UBI in drivers/mtd/ubi/barebox.c Of those four, first two are marked DEVFS_IS_CHARACTER_DEV and implement only .write() operation and the last two don't implement anything but .ioctl(). While there's probably no meaningful way to use lseek() against any of those devices, there doesn't seem to be any harm in allowing it either. Change devfs_lseek() to ignore absense of .lseek() callback and drop dev_lseek_default() and all references to it in the codebase.

* i2c: introduce device_i2c_driver() macroMarco Felsch2018-10-191-9/+1
| | | | | | | | | Add macro and dependency to avoid boilerplate code. Since now simple i2c drivers only have to include the i2c.h header and call the device_i2c_driver() macro to register a i2c device driver.

* rename file_operations -> cdev_operationsSascha Hauer2018-04-061-1/+1
| | | | | | | | Linux also has struct file_operations which are something different. Rename our file_operations to cdev_operations which better matches what we have. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-2/+2
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* treewide: Add missing includesSascha Hauer2013-11-081-0/+1
| | | | | | | | A lot of files rely on include/driver.h including include/of.h (and this including include/errno.h. include the files explicitly so we can eventually get rid of including of.h from driver.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | mfd: stmpe: Add devicetree probe supportSascha Hauer2013-06-061-2/+30
|/ | | | | | | | Our driver matches stmpe-i2c and stmpe-spi. It seems the device we really support is the stmpe1601, so use this one for matching the devicetree compatible. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* I2C: Put I2C devices on their own busSascha Hauer2012-09-141-1/+1
| | | | | | | | This patch adds a I2C bus on which the I2C devices and drivers register. This makes it cleaner as I2C devices won't accidently end up probed by a platform_device driver. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mfd: add stmpe-i2c driverSteffen Trumtrar2012-09-051-0/+153
The stmpe mfds can be connected via i2c and spi. This driver provides the basic infrastructure for the i2c kind. It can be added as a normal i2c-device in the board code. To enable functions a platform_data struct has to be provided, that describes what parts of the chip are to be used.
