If we can't find a replacement in the software table, we accidently leave a duplicate in the HW table. This patch ensures that duplicate is marked as not valid. What we should do is find the replacement in the software table, before we find a victim in the HW table - but its too late in the release cycle to do that much restructuring of this code. Rather that duplicate code, connect Hardware Errors (irq5) into trap_c, so user space processes get killed properly. The rest of irq_panic() can be moved into traps.c (later) There is still a small corner case that causes problems when a pheriperal interrupt goes off a single cycle before a user space hardware error. This causes a kernel panic, rather than the user space process being killed. But, this checkin makes things work in 99.9% of the cases, and is a vast improvement from what is there today (which fails 100% of the time).

* | i2c-au1550: properly terminate zero-byte transfersManuel Lauss2008-01-271-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | i2c: Add i2c_new_dummy() utilityDavid Brownell2008-01-272-1/+64
| | | | | | | | | | | | | | | | | | This adds a i2c_new_dummy() primitive to help work with devices that consume multiple addresses, which include many I2C eeproms and at least one RTC. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* | i2c-remove-redundant-i2c_client-list.patchDavid Brownell2008-01-271-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | i2c: Drivers stop using the redundant client listJean Delvare2008-01-272-19/+40
| | | | | | | | | | | | | | | | | | | | | | 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).

* | i2c: Stop using the redundant client listDavid Brownell2008-01-273-52/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

* | i2c-piix4: Drop redundant PCI function number checkJean Delvare2008-01-271-26/+15
| | | | | | | | | | | | | | Checking the PCI function number doesn't add any value, and it makes adding dynamic IDs to the driver more difficult. Drop this check. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* | i2c: Let the user specify PCI driver data through new_idJean Delvare2008-01-272-0/+10
| | | | | | | | | | | | | | | | | | | | | | 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: Jean Delvare <khali@linux-fr.org> Acked-by: Greg 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: Jean Delvare <khali@linux-fr.org>
* | i2c-i801: Implement I2C block read supportJean Delvare2008-01-272-28/+56
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Clear special mode bits (PEC, block buffer) at driver load time, you never know in which state the device was left by its last user. Also make sure that we reset the block buffer mode at the end of every transaction, not only when PEC was used. Signed-off-by: Jean Delvare <khali@linux-fr.org>

| | | | | | | | | | | | | | | | | | | | Use more standard prototypes for i2c_use_client() and i2c_release_client().

| | | | | | | | | | | | | | | | | | | | I2C adapter drivers are supposed to handle retries on nack by themselves if they do, so there's no point in setting .retries if they don't.

Lost arbitration is not currently handled, so don't even list it as an option in the error message.
