* 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 Felsch2018-10-191-8/+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>

| | | | | | | | | | | | | | 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>
* | I2C: Put I2C devices on their own busSascha Hauer2012-09-141-2/+2
|/ | | | | | | | 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>
