* i2c: Inform about deprecated chips directoryWolfram Sang2008-10-22

* i2c: MPC8349E-mITX Power Management and GPIO expander driverAnton Vorontsov2008-10-13
| | | | | | | | | | On MPC8349E-mITX, MPC8315E-RDB and MPC837x-RDB boards there is a Freescale MC9S08QG8 (MCU) chip with the custom firmware pre-programmed. The chip is used to power-off the board by the software, and to control some GPIO pins. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* gpiolib: allow user-selectionMichael Buesch2008-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

* i2c: Deprecate the legacy gpio driversDavid Brownell2008-07-14
| | | | | | | | | | | | The legacy pcf8574 and pcf8575 drivers should be avoided on systems using the new gpiolib code, and generally deprecated in the same way the legacy pca9539 driver is deprecated. Also, correct the pca9539 deprecation to match the current name of the preferred driver: pca953x, supporting several more chips.

* OMAP: add TI TWL92330/Menelaus Power Management chip driverTony Lindgren2007-07-17
| | | | | | | | | | | | | | | | | | | | | | Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.

* i2c: Deprecate legacy RTC driversJean Delvare2007-07-12
| | | | | | | | | | | | | | | | | | | We have a new RTC subsystem with better drivers. Legacy driver status: * ds1337: The DS1337 and DS1339 are now supported by the rtc-ds1307 driver, so it looks to me like we could even delete the ds1337 driver right away. * ds1374: Will soon be replaced with Scott Wood's rtc-ds1374 driver. * m41t00: The M41T00 is supported by the rtc-ds1307 driver. For the M41T81 and M41T85, the rtc-m41t80 driver written by Atsushi Nemoto should work. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <a.zummo@towertech.it> Acked-by: Mark A.

* [PATCH] hwmon: hwmon vs i2c, second round (07/11)Jean Delvare2005-09-05
| | | | | | | | | | | | | The only part left in i2c-sensor is the VRM/VRD/VID handling code. This is in no way related to i2c, so it doesn't belong there. Move the code to hwmon, where it belongs. Note that not all hardware monitoring drivers do VRM/VRD/VID operations, so less drivers depend on hwmon-vid than there were depending on i2c-sensor.

These chips are compatible with the other ones already supported by the driver, so I see no reason not to support them, especially when the Linux 2.4 version of the driver does already.

* [PATCH] I2C: New hardware monitoring driver: w83627ehfJean Delvare2005-06-22
| | | | | | | | | | | | | | | | | | | | | | This is a new hardware monitoring driver, w83627ehf, which supports the Winbond W83627EHF Super-I/O chip. The driver is not complete, but already usable. It only implements fan speed and temperature monitoring, while the chip also supports voltage inputs with VID, PWM output and temperature sensor selection. I have no more time to work on this, but anyone with supported hardware could add the missing functionalities later. This driver is largely derived from the w83627hf driver. Thanks to Leon Moonen and Steve Cliffe for tesing the preliminary versions of my driver and reporting the problems they encountered. Thanks to Grant Coady for noticing and fixing various corner cases in the fan management. This third version of the driver hopefully addresses all the issues the original version had.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
