2005-12-16[PATCH] i2c: Fix i2c-mv64xxx compilation errorMark A. Greer

2005-11-07[PATCH] i2c-viapro: Some adjustmentsJean Delvare
The big i2c-viapro SMBus driver update which went into 2.6.14-git1 introduced a few minor issues. Nothing critical, but I would like a few adjustments to be merged in to fix the following problems: * VIA should not be spelled Via. * Frodo Looijaard and Philip Edelbrock did not write the i2c-viapro driver. * When debugging is disabled, half of messages would be logged. * Drop an unneeded masking. * Some port reads can be avoided now that the transaction size is passed as a parameter to vt596_transaction(). * SMBus Receive Byte transactions are used for probing too (for EEPROMs), so hide errors on these too.

2005-10-28[PATCH] i2c: Fix i2c-elektor on AlphaStig Telfer
This patch updates the i2c-elektor driver, enabling it to compile cleanly, load and run. The key change is that it uses the new __iomem/iowrite8/ioread8 functions to abstract the direct or memory-mapped variants of register access. Also, the original driver would crash on module load on the Alpha because the PCI memory region was not remapped into kernel memory. I have managed the following testing: * compiled and tested it on my Alpha UP2000+ system. * compiles cleanly for x86 but I don't have the hardware to test.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-09-22[PATCH] ppc64: SMU driver update & i2c supportBenjamin Herrenschmidt
The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

2005-09-05[PATCH] I2C: Drop probe parameter of i2c-keywestJean Delvare
The i2c-keywest driver has a "probe" module parameter which enables bus scanning at load time. This can be done in userspace with the i2cdetect tool (part of the lm_sensors package) instead. What's more, i2cdetect gives more control on the way the bus is scanned, and is safer (i2c-keywest currently scans reserved addresses and doesn't properly handle the famous 24RF08 corruption case.) Thus, I would propose that this module parameter be simply dropped.

2005-09-05[PATCH] I2C: Kill i2c_algorithm.id (6/7)Jean Delvare
In theory, there should be no more users of I2C_ALGO_* at this point. However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.
