* i2c-viapro: Add support for the VT8237SJean Delvare2008-01-273-3/+8
| | | | | | | Add support for another variant of the VT8237. I couldn't test I2C block support but I assume it is present as well. 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>
* i2c-pxa: Add polling transferMike Rapoport2008-01-273-12/+133
| | | | | | | | | | Add polling I2C transfer implementation for PXA I2C. This is needed for cases where I2C transactions have to occur at times interrups are disabled. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Acked-by: eric miao <eric.miao@marvell.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Support i2c_transfer in atomic contextsMike Rapoport2008-01-271-1/+11
| | | | | | | | | Allow i2c_transfer to be called in contexts where sleeping is not allowed. It is the reponsability of the caller to ensure that the underlying i2c bus driver will not sleep either. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-sibyte: Remove the bus scan module parameterJean Delvare2008-01-271-28/+1
| | | | | | | | | | The implementation is unsafe, and anyway one can achieve the same from userspace using i2c-dev + i2cdetect. Also tag i2c_sibyte_add_bus __init. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Ralf Baechle <ralf@linux-mips.org>
* i2c: Discard unused driver IDsJean Delvare2008-01-271-60/+0
| | | | | | | | | 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. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-i801: Clear special mode bits as neededJean Delvare2008-01-271-1/+6
| | | | | | | | | | 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>
* i2c-i801: More explicit names for chip featuresJean Delvare2008-01-271-9/+15
| | | | | | | Use separate flags with explicit names to describe the features of the ICH chip. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-i801: Document which chip support what featureJean Delvare2008-01-271-24/+33
| | | | | | | Provide a clearer documentation of which additional features each ICH chip support, and which of these the driver supports. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c/tps65010: move header to <linux/i2c/...>David Brownell2008-01-2711-17/+14
| | | | | | | | | Move the tps65010 header file from the OMAP arch directory to the more generic <linux/i2c/...> directory, and remove the spurious dependency of this driver on OMAP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Rename main mutexJean Delvare2008-01-271-15/+15
| | | | | | | Rename the main mutex in i2c-core from core_lists to core_lock. This makes more sense now that the redundant lists are gone. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Drop redundant i2c_driver.listJean Delvare2008-01-272-24/+35
| | | | | | | | i2c_driver.list is superfluous, this list duplicates the one maintained by the driver core. Drop it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: David Brownell <dbrownell@users.sourceforge.net>
* i2c: Drop redundant i2c_adapter.listJean Delvare2008-01-273-24/+10
| | | | | | | | i2c_adapter.list is superfluous, this list duplicates the one maintained by the driver core. Drop it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: David Brownell <dbrownell@users.sourceforge.net>
* i2c: Change prototypes of refcounting functionsJean Delvare2008-01-273-27/+26
| | | | | | | | | | Use more standard prototypes for i2c_use_client() and i2c_release_client(). The former now returns a pointer to the client, and the latter no longer returns anything. This matches what all other subsystems do. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
* i2c: Use the driver model reference countingJean Delvare2008-01-273-48/+2
| | | | | | | | Don't implement our own reference counting mechanism for i2c clients when the driver model already has one. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
* i2c: Deprecate drivers for I2C buses on video adaptersJean Delvare2008-01-272-4/+20
| | | | | | | The framebuffer drivers for these pieces of hardware include support for the DDC/I2C buses, so there is no need for separate drivers. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Don't uselessly set i2c_adapter.retriesJean Delvare2008-01-275-6/+0
| | | | | | | | | | 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. As this retry mechanism is going away (at least in its current form), clean this up now so that we don't get build failures later. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Kill rogue driver IDsJean Delvare2008-01-273-7/+0
| | | | | | I2C driver IDs are optional, so if you don't need one, just omit it. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* i2c: Constify client address dataMark M. Hoffman2008-01-273-60/+46
| | | | | | | | This patch allows much of the I2C client address data to move from initdata into text. Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-algo-pcf: Delete broken 10-bit address supportJean Delvare2008-01-271-72/+13
| | | | | | | | The 10-bit address support in i2c-algo-pcf is so heavily broken that it can't have ever been used. Nobody ever complained, so I'll take it that nobody needs it. Let's just delete it. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c-algo-bit: Fix NAK/ARB commentsDavid Brownell2008-01-271-4/+20
| | | | | | | | | | | | | 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. Don't return bogus EFAULT code for inappropriate NAK; EIO is better, there is no bad userspace address in question.

* i2c: some overdue driver removalAdrian Bunk2008-01-276-213/+0
| | | | | | | | | | This patch contains the overdue removal of three I2C drivers.

* i2c-pasemi: use i2c_add_numbered_adapter()Olof Johansson2008-01-271-1/+2
| | | | | | | | | | | | | Use numbered adapter registration to always have the same hardware bus show up at the same number. PWRficient 1682M has three buses, they are all on the same PCI device but different functions. So do the simple thing and register them based on function number. Future products, if having a different number of busses, are expected to have similar behaviour w.r.t. device/function layout.

* i2c-nforce2: The nForce2 can do block transactionsJean Delvare2008-01-271-0/+1
| | | | | | | | | My guess is that all the chips supported by this driver support block transactions and reset, but for now we play it safe and only list the ones for which this was actually tested. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Oleg Ryjkov <olegr@olegr.ca>
