* i2c: Kill the old driver matching schemeJean Delvare2008-05-18
| | | | | | | Remove the old driver_name/type scheme for i2c driver matching. Only the standard aliasing model will be used from now on. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Match dummy devices by typeJean Delvare2008-05-11
| | | | | | | | | | | | As the old driver_name/type matching scheme is going away soon, change the dummy device mechanism to use the new matching scheme. This has the downside that dummy i2c clients can no longer choose their name, they'll all appear as "dummy" in sysfs and in log messages. I don't think it is a problem in practice though, as there is little reason to use these i2c clients to log messages. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Convert most new-style drivers to use module aliasingJean Delvare2008-04-29
| | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

* i2c: Add support for device alias namesJean Delvare2008-04-29
| | | | | | | | | | | | | | Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported.

* i2c: Add i2c_new_dummy() utilityDavid Brownell2008-01-27

* i2c: Stop using the redundant client listDavid Brownell2008-01-27
| | | | | | | | | | | | | | | | | | | | | | | | | 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: Remove i2c_algorithm.algo_control()David Brownell2007-10-13
| | | | | | | | | | | | | | | | | | This removes: - An effectively unused hook: i2c_algorithm.algo_control. - The i2c_control() call, used only by i2c-dev to call that unused hook or set two barely supported adapter params. (That param setting moves into i2c-dev.c ... still iffy due to lack of locking, but no other changes.) As shown by diffstat, this is a net code shrink.

* | i2c: Fix the i2c_smbus_read_i2c_block_data() prototypeJean Delvare2007-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let the drivers specify how many bytes they want to read with i2c_smbus_read_i2c_block_data(). So far, the block count was hard-coded to I2C_SMBUS_BLOCK_MAX (32), which did not make much sense. Many driver authors complained about this before, and I believe it's about time to fix it. Right now, authors have to do technically stupid things, such as individual byte reads or full-fledged I2C messaging, to work around the problem. We do not want to encourage that. I even found that some bus drivers (e.g. i2c-amd8111) already implemented I2C block read the "right" way, that is, they didn't follow the old, broken standard. The fact that it was never noticed before just shows how little i2c_smbus_read_i2c_block_data() was used, which isn't that surprising given how broken its prototype was so far. There are some obvious compatiblity considerations: * This changes the i2c_smbus_read_i2c_block_data() prototype. Users outside the kernel tree will notice at compilation time, and will have to update their code. * User-space has access to i2c_smbus_xfer() directly using i2c-dev, so the changed expectations would affect tools such as i2cdump. In order to preserve binary compatibility, we give I2C_SMBUS_I2C_BLOCK_DATA a new numeric value, and define I2C_SMBUS_I2C_BLOCK_BROKEN with the old numeric value. When i2c-dev receives a transaction with the old value, it can convert it to the new format on the fly. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* i2c: Move i2c-isa-only exported symbol declarationsJean Delvare2007-05-01

* i2c: Add i2c_new_probed_device()Jean Delvare2007-05-01
| | | | | | | | | | | | | | | | Add a new helper function to instantiate an i2c device. It is meant as a replacement for i2c_new_device() when you don't know for sure at which address your I2C/SMBus device lives. This happens frequently on TV adapters for example, you know there is a tuner chip on the bus, but depending on the exact board model and revision, it can live at different addresses. So, the new i2c_new_probed_device() function will probe the bus according to a list of addresses, and as soon as one of these addresses responds, it will call i2c_new_device() on that one address. This function will make it possible to port the old i2c drivers to the new model quickly. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Add i2c_add_numbered_adapter()David Brownell2007-05-01
| | | | | | | | | | | | | | | This adds a call, i2c_add_numbered_adapter(), registering an I2C adapter with a specific bus number and then creating I2C device nodes for any pre-declared devices on that bus. It builds on previous patches adding I2C probe() and remove() support, and that pre-declaration of devices. This completes the core support for "new style" I2C device drivers. Those follow the standard driver model for binding devices to drivers (using probe and remove methods) rather than a legacy model (where the driver tries to autoconfigure each bus, and registers devices itself).

* i2c: Add i2c_board_info and i2c_new_device()David Brownell2007-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides partial support for new-style I2C driver binding. It builds on "struct i2c_board_info" declarations that identify I2C devices on a given board. This is needed on systems with I2C devices that can't be fully probed and/or autoconfigured, such as many embedded Linux configurations where the way a given I2C device is wired may affect how it must be used. There are two models for declaring such devices: * LATE -- using a public function i2c_new_device(). This lets modules declare I2C devices found *AFTER* a given I2C adapter becomes available. For example, a PCI card could create adapters giving access to utility chips on that card, and this would be used to associate those chips with those adapters. * EARLY -- from arch_initcall() level code, using a non-exported function i2c_register_board_info(). This copies the declarations *BEFORE* such an i2c_adapter becomes available, arranging that i2c_new_device() will be called later when i2c-core registers the relevant i2c_adapter. For example, arch/.../.../board-*.c files would declare the I2C devices along with their platform data, and I2C devices would behave much like PNPACPI devices. (That is, both enumerate from board-specific tables.) To match the exported i2c_new_device(), the previously-private function i2c_unregister_device() is now exported. Pending later patches using these new APIs, this is effectively a NOP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: i2c stack can remove()David Brownell2007-05-01

* i2c: i2c stack can probe()David Brownell2007-05-01
| | | | | | | | | | | | | | | | | | | | | | | One of a series of I2C infrastructure updates to support enumeration using the standard Linux driver model. This patch updates probe() and associated hotplug/coldplug support, but not remove(). Nothing yet _uses_ it to create I2C devices, so those hotplug/coldplug mechanisms will be the only externally visible change. This patch will be an overall NOP since the I2C stack doesn't yet create clients/devices except as part of binding them to legacy drivers. Some code is moved earlier in the source code, helping group more of the per-device infrastructure in one place and simplifying handling per-device attributes. Terminology being adopted: "legacy drivers" create devices (i2c_client) themselves, while "new style" ones follow the driver model (the i2c_client is handed to the probe routine). It's an either/or thing; the two models don't mix, and drivers that try mixing them won't even be registered.

* i2c: Emulate SMBus block read over I2CJean Delvare2007-05-01
| | | | | | | | | | Let the I2C bus drivers emulate the SMBus Block Read and Block Process Call transactions if they wish.

* i2c: Shrink struct i2c_clientDavid Brownell2007-05-01
| | | | | | | | | | | | | | | | | | | | | | This shrinks the size of "struct i2c_client" by 40 bytes: - Substantially shrinks the string used to identify the chip type - The "flags" don't need to be so big - Removes some internal padding It also adds kerneldoc for that struct, explaining how "name" is really a chip type identifier; it's otherwise potentially confusing. Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name and for i2c_adapter.name, this needed to affect i2c_adapter too. The adapters which used that symbol now use the more-obviously-correct idiom of taking the size of that field. JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to avoid wasting space in padding.

Instead, set the class of i2c_adapter.dev to i2c_adapter_class, so that a symlink will be created for every i2c_adapter in /sys/class/i2c-adapter. The same change must be mirrored to i2c-isa as it duplicates some of the i2c-core functionalities. User-space tools and libraries might need some adjustments. In particular, libsensors from lm_sensors 2.10.3 or later is required for proper discovery of i2c adapter names after this change. Signed-off-by: Jean Delvare <khali@linux-fr.org>
