2010-03-02i2c-parport-light: Add SMBus alert supportJean Delvare
Add support for the SMBus alert mechanism to the i2c-parport-light driver. The ADM1032 evaluation board at least is properly wired for this. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Trent Piepho <tpiepho@freescale.com>

2009-06-15i2c-viapro: Add new PCI device ID for VX855Harald Welte
The south bridge of the VIA VX855 chipset has a different PCI Device ID so i2c-viapro.c needs to be updated with this. Signed-off-by: Harald Welte <HaraldWelte@viatech.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-13i2c-ocores: Can add I2C devices to the busRichard Röjfors
There is sometimes a need for the ocores driver to add devices to the bus when installed. i2c_register_board_info can not always be used, because the I2C devices are not known at an early state, they could for instance be connected on a I2C bus on a PCI device which has the Open Cores IP. i2c_new_device can not be used in all cases either since the resulting bus nummer might be unknown. The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

The MCP78S and MCP79 appear to be compatible with the previous nForce chips as far as the SMBus controller is concerned. The MCP67 and MCP73 were not tested yet but I'd be very surprised if they weren't compatible too.

2008-01-27i2c-viapro: Add support for the VT8237SJean Delvare
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-i801: Implement I2C block read supportJean Delvare
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.

2007-08-31i2c-piix4: Fix SB700 PCI device IDShane Huang
We find that SB700 and SB800 use the same SMBus device ID as SB600, which is 0x4385, instead of the already submitted 0x4395. Besides removing the wrong SB700 device ID, add SB800 support to kernel, by renaming the PCI_DEVICE_ID_ATI_IXP600_SMBUS into PCI_DEVICE_ID_ATI_SBX00_SMBUS.

2007-07-12i2c-i801: Use the internal 32-byte buffer on ICH4+Oleg Ryjkov
Add an ability to utilize the internal SRAM buffer on ICH4 and newer host controllers to speed up execution of block operations. I've split the code so that it is more clear which block transaction is performed. First of all the host controller's type is identified. isich4 is set when we think that the controller has the internal buffer. Then, before every block transaction, if isich4 is set, we attempt to enable the E32B bit in SMBAUXCTL register.

2007-02-13i2c-parport: Add support for One For All remote JP1 interfaceJonathan McDowell
This simple patch adds support to i2c-parport for the One For All remote JP1 parallel port interfaces which can be found detailed at: http://www.hifi-remote.com/jp1/hardware.shtml These allow access to the internal configuration EEPROM on various remote controls and there are a variety of Windows tools that make use of this hardware. I have tested this patch with the "simple" parallel port device and a One For All URC-7562 and confirmed that the data read using the eeprom i2c driver matches that returned by the Windows "IR" JP1 tool.

Add support for the new nForce4 MCP51 (also known as nForce 410 or 430) and nForce4 MCP55 to the i2c-nforce2 driver. Some code changes were required because the base I/O address registers have changed in these versions. Standard BARs are now being used, while the original nForce2 chips used non-standard ones.

2006-06-22[PATCH] I2C: i2c-piix4: Remove the fix_hstcfg parameterRudolf Marek
This patch removes the fix_hstcfg option from the driver and related SMBus Interrupt Select register magic because now we know what are valid values for this register. This patch updates the documentation and adds new IRQ mode check so we are sure not to miss any new "unusual" value. The PCI quirk for users of fix_hstcfg was not developed because the chipset lacks of subsystem ID registers and DMI is stated "To be filled". Impact to existing systems is minimal because the problem showed up on motherboards like 10 years back. On the other hand users of newer Serverworks and HT1000 systems won't be misleaded by the message suggesting to try the fix_hstcfg any more.

2006-04-14[PATCH] i2c-parport: Make type parameter mandatoryMark M. Hoffman
This patch forces the user to specify what type of adapter is present when loading i2c-parport or i2c-parport-light. If none is specified, the driver init simply fails - instead of assuming adapter type 0. This alleviates the sometimes lengthy boot time delays which can be caused by accidentally building one of these into a kernel along with several i2c slave drivers that have lengthy probe routines (e.g. hwmon drivers). Kconfig and documentation updated accordingly. Signed-off-by: Mark M.

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.
