The MS Presenter 8000 bluetooth mouse is a "dual-use" device: If you press a button on the top, you can turn it around and find special keys on the other side, useful for presentations. This patch maps those three bottom-keys that are not already detected to the intended functions. The magic bottom on the top is mapped to F5 when we switch from mouse to presenter mode in order to activate the presentation mode in the related software (e.g. OpenOffice).

Zero-bytes transfers would leave the bus transaction unfinished (no i2c stop is sent), with the following transfer actually sending the slave address to the previously addressed device, resulting in weird device failures (e.g. reset minute register values in my RTC). This patch instructs the controller to send an I2C STOP right after the slave address in case of a zero-byte transfer.

由 David Brownell 提交于
This goes on top of the patch removing most i2c_adapter.clients usage, updating i2c_attach_client: - Don't call device_register() while holding clist_lock. This removes a self-deadlock when on the i2c_driver.probe() path, for drivers that need to attach new devices (e.g. dummies). - Remove a redundant address check. The driver model core does this as a consequence of guaranteeing unique names. - Move the "device registered" diagnostic so that it never lies; previously, on error paths it would falsely report success.

The redundant i2c client list maintained by i2c-core is going away soon, so drivers should stop using it now. Instead, they can use the standard iterator provided by the device driver model (device_for_each_child).

The i2c_adapter.clients list of i2c_client nodes duplicates driver model state. This patch starts removing that list, letting us remove most existing users of those i2c-core lists. * The core I2C code now iterates over the driver model's list instead of the i2c-internal one in some places where it's safe: - Passing a command/ioctl to each client, a mechanims used almost exclusively by DVB adapters; - Device address checking, in both i2c-core and i2c-dev. * Provide i2c_verify_client() to use with driver model iterators. * Flag the relevant i2c_adapter and i2c_client fields as deprecated, to help prevent new users from appearing. For the moment the list needs to stick around, since some issues show up when deleting devices created by legacy I2C drivers. (They don't follow standard driver model rules. Removing those devices can cause self-deadlocks.) Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NJean Delvare <khali@linux-fr.org>

The i2c-amd756 and i2c-viapro drivers make use of the driver_data field of the PCI device ID. When adding device IDs dynamically (by writing to the new_id sysfs file) you cannot set the value of this field by default. It has to be allowed explicitly. Do that, and check the value so that the user can't crash the kernel accidentally. Signed-off-by: NJean Delvare <khali@linux-fr.org> Acked-by: NGreg Kroah-Hartman <gregkh@suse.de>

Discard all I2C driver IDs that aren't used anywhere. That's not just a couple of them, but more like 49 or one quarter of all defined IDs! And this is just a first pass, next will come all IDs that are set but never used, or used but never set. Signed-off-by: NJean Delvare <khali@linux-fr.org>

I2C block read is supported since the ICH5. I couldn't get it to work using the block buffer, so it's using the old-style byte-by-byte mode for now. Note: I'm also updating the driver author... The i2c-i801 driver was really written by Mark Studebaker, even though he based his work on the i2c-piix4 driver which was written by Philip Edelbrock.

Update comments and logging on return path for byte writes. NAK is an error, to be reported or optionally ignored. Timeouts are always errors. Lost arbitration is not currently handled, so don't even list it as an option in the error message.
