* i2c-i801: Restore the device state before leavingJean Delvare2007-03-22
| | | | | | | | | | | | | Restore the original host configuration on driver unload and on suspend. In particular this returns the SMBus master in I2C mode if it was originally in I2C mode, which should help with suspend/resume if the BIOS expects to find the SMBus master in I2C mode.

* | [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* | i2c: Remove the warning on missing adapter deviceJean Delvare2007-02-13
| | | | | | | | | | | | | | | | | | Now that the i2c_adapter migration plan changed and we are going to keep i2c_adapter.dev, it's no longer that urgent to add a proper device to all i2c_adapter drivers.

If any i2c drivers were previously using the old suspend/resume calls in "struct driver", they were getting warning messages ... and will now no longer work. Other than that, this patch changes no behaviors; and it lets I2C drivers use conventional PM and shutdown support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2c-ali1563 initialization looks quite broken to me: * If the I/O space isn't enabled, we forcibly set 3 bits in the PCI configuration space instead of just the one enabling the I/O space. * After that we pretend to check if the write worked, but we don't actually read the new value from the register. * It's probably not a good idea to enable the I/O space if no base address has been set. So I propose the following changes to that part of the driver: * Merge ali1563_enable() into ali1563_setup(). * Check the base address before the I/O space enabled bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have a Marvell board which has the same i2c hw block than mv64xxx, so I'm trying to use i2c-mv64xxx driver.

| | | | | | | | | | | | | | | | | | | Flag i2c_adapter.dev for removal after userspace tools get upgraded, and include a near-term code migration aid to facilitate this: - The class device gets the name attribute it should have had.

Sysfs based tools and libraries can start converting right away. - Issue a warning for legacy adapter drivers that don't provide any physical device node; so systems with those drivers will know to fix this problem earlier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a custom board with ds1337 RTC I found that upgrade from 2.6.15 to 2.6.18 broke RTC support. The main problem are changes to ds1337_init_client(). When a ds1337 recognizes a problem (e.g. power or clock failure) bit 7 in status register is set. This has to be reset by writing 0 to status register. But since there are only 16 byte written to the chip and the first byte is interpreted as an address, the status register (which is the 16th) is never written. The other problem is, that initializing all registers to zero is not valid for day, date and month register. Funny enough this is checked by ds1337_detect(), which depends on this values not being zero. So then treated by ds1337_init_client() the ds1337 is not detected anymore, whereas the failure bit in the status register is still set.

* | i2c: Whitespace cleanupsDavid Brownell2006-12-10
| | | | | | | | | | | | | | | | Remove extraneous whitespace from various i2c headers and core files, like space-before-tab and whitespace at end of line. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* | i2c: Use put_user instead of copy_to_user where possibleJean Delvare2006-12-10
| | | | | | | | | | | | | | This speeds up the I2C_FUNCS ioctl by 5 to 8% in my tests. Signed-off-by: Jean Delvare <khali@linux-fr.org> Laughed-at-by: Mark M. Hoffman <mhoffman@lightlink.com>
* | i2c: New Atmel AT91 bus driverAndrew Victor2006-12-10
| | | | | | | | | | | | | | | | | | | | Add support for the I2C (Two-wire interface) controller integrated in the Atmel AT91RM9200 processor. This driver should also be usable on the Atmel AT91SAM9261 and AT91SAM9260 processors. Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Mark M.

* | i2c: Add support for nested i2c bus lockingJiri Kosina2006-12-10
| | | | | | | | | | | | | | | | | | | | This patch adds the 'level' field into the i2c_adapter structure, which is used to represent the 'logical' level of nesting for the purposes of lockdep. This field is then used in the i2c_transfer() function, to acquire the per-adapter bus_lock with correct nesting level.

* | i2c: Cleanups to the i2c-nforce2 bus driverHans-Frieder Vogt2006-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary of changes: - fixes: o legacy I/O region size is 64 bytes, not 8 bytes - general cleanup: o removed code for the unsupported I2C block data, block data, proc call and block proc call transfer modes o removed detail warnings about unsupported modes that are covered in a general warning (unsupported transaction...) anyway o removed necessity of a definition of struct i2c_adapter o moved definition of struct i2c_algorithm, making forward declarations of nforce2_access and nforce2_func unnecessary - minor changes: o in the description mention the nForce 5xx chipsets o changes my e-mail address in MODULE_AUTHOR Theses cleanups shrink the driver binary size from 4.0 kB to 2.7 kB on i386.

* | i2c: Add request/release_mem_region to i2c-ibm_iic bus driverJean-Baptiste Maneyrol2006-12-10
| | | | | | | | | | | | | | | | | | Reserving I/O memory for a driver with request_mem_region is necessary to avoid memory access conflicts. Even if it's never going to happen, it is cleaner and it allows to monitor I/O memory used in /proc/iomem.
