2008-01-28rtc: rtc-sh: Split out the CPU defs to asm/cpu/.Paul Mundt1-19/+1
With all of the different CPU types this was getting a but unwieldly. Since sh64 is now integrated, we don't have to worry about multiple architectures caring about the header definitions. Split out the defs for each asm/cpu/ to make rtc-sh slightly less visually offensive. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Add SH7263 CPU support.Paul Mundt1-2/+4
This adds support for the SH7263 (SH-2A) CPU. This particular CPU is a superset of SH7203, adding some additional peripheral blocks and hooking up additional (reserved on SH7203) vectors in the INTC block. No visibly nasty surprises, yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-01-27i2c-bfin-twi: Register adapter with a specific bus numberKalle Pokki1-1/+2
All the users of this driver explicitly specify the I2C bus numbers to be used in their platform data. Make the driver respect that. Signed-off-by: Kalle Pokki <kalle.pokki@eke.fi> Cc: Bryan Wu <bryan.wu@analog.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c-au1550: Convert to platform driverManuel Lauss2-96/+102
Convert the i2c-au1550 bus driver to platform driver, and register a platform device for the Alchemy Db/Pb series of boards. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c-au1550: properly terminate zero-byte transfersManuel Lauss1-3/+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.

2008-01-27mpc-i2c: Propagate error values properlyJon Smirl1-12/+16
Propagate the error values returned by i2c_wait() instead of overriding them with a meaningless -1. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c: Add i2c_new_dummy() utilityDavid Brownell1-1/+58
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>
2008-01-27i2c: Drop legacy locking in i2c_new_probed_deviceJean Delvare1-2/+0
It is no longer required to hold adapter->clist_lock to call i2c_check_addr. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net>
2008-01-27i2c: Limit locking scope in i2c_detach_clientJean Delvare1-1/+2
We only need to hold adapter->clist_lock when we touch the client list. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c-remove-redundant-i2c_client-list.patchDavid Brownell1-14/+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.

2008-01-27i2c: Drivers stop using the redundant client listJean Delvare2-19/+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). Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <david-b@pacbell.net> Cc: Michael Hunold <michael@mihu.de>
2008-01-27i2c: Stop using the redundant client listDavid Brownell2-49/+58
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>
2008-01-27i2c-viapro: Add support for the VT8237SJean Delvare2-2/+6
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>
2008-01-27i2c-piix4: Drop redundant PCI function number checkJean Delvare1-26/+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>
2008-01-27i2c: Let the user specify PCI driver data through new_idJean Delvare2-0/+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>
2008-01-27i2c-pxa: Add polling transferMike Rapoport1-12/+121
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>
2008-01-27i2c: Support i2c_transfer in atomic contextsMike Rapoport1-1/+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>
2008-01-27i2c-sibyte: Remove the bus scan module parameterJean Delvare1-28/+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>
2008-01-27i2c-i801: Implement I2C block read supportJean Delvare1-25/+54
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>
2008-01-27i2c-i801: Clear special mode bits as neededJean Delvare1-1/+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>
2008-01-27i2c-i801: More explicit names for chip featuresJean Delvare1-9/+15
Use separate flags with explicit names to describe the features of the ICH chip. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-01-27i2c-i801: Document which chip support what featureJean Delvare1-24/+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>
2008-01-27i2c/tps65010: move header to <linux/i2c/...>David Brownell6-9/+5
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>
2008-01-27i2c: Rename main mutexJean Delvare1-15/+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>
2008-01-27i2c: Drop redundant i2c_driver.listJean Delvare1-23/+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>

2008-01-27i2c: Change prototypes of refcounting functionsJean Delvare2-22/+24
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>
2008-01-27i2c: Use the driver model reference countingJean Delvare2-45/+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>
2008-01-27i2c: Deprecate drivers for I2C buses on video adaptersJean Delvare1-4/+13
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>
2008-01-27i2c: Don't uselessly set i2c_adapter.retriesJean Delvare5-6/+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>
2008-01-27i2c: Kill rogue driver IDsJean Delvare2-4/+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>

2008-01-27i2c-algo-pcf: Delete broken 10-bit address supportJean Delvare1-72/+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>
2008-01-27i2c-algo-bit: Fix NAK/ARB commentsDavid Brownell1-4/+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.

2008-01-27i2c-pasemi: use i2c_add_numbered_adapter()Olof Johansson1-1/+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.
