* Input: adp5588-keys - support GPI events for ADP5588 devicesXiaolong CHEN2010-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | A column or row configured as a GPI can be programmed to be part of the key event table and therefore also capable of generating a key event interrupt. A key event interrupt caused by a GPI follows the same process flow as a key event interrupt caused by a key press. GPIs configured as part of the key event table allow single key switches and other GPI interrupts to be monitored. As part of the event table, GPIs are represented by the decimal value 97 (0x61 or 1100001) through the decimal value 114 (0x72 or 1110010). See table below for GPI event number assignments for rows and columns.

| | | | | | | | | | | | | | | | | | This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to use only the external HW resistor >=470 Ohm for the assured functionality in HS mode. While testing the I2C in High Speed mode, it was discovered that without a proper pull-up resistor, there is data corruption during multi-byte transfer. RTC(time_set) test case was used for testing. From the analysis done, it was concluded that ideally we need a pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for assured performance in HS mode.

* OMAP4: PMIC: Add support for twl6030 codecMisael Lopez Cruz2010-02-24
| | | | | | | | | | | | | | | | | | | | | | | In order to have TWL6030 CODEC driver as a platform driver, codec data should be passed through twl_platform_data structure. For twl6030 audio codec, the following data may be passed: - audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high transition powers codec up. Setting audpwron_gpio to a negative value means that codec will use manual power sequence instead of automatic sequence - naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line to low when an interrupt (codec ready, plug insertion/removal, etc) is detected However, codec driver can operate if any or none of them are passed.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New MFD child to twl4030 MFD device. Reason for the twl4030_codec MFD: the vibra control is actually in the codec part of the twl4030. If both the vibra and the audio functionality is needed from the twl4030 at the same time, than they need to control the codec power and APLL at the same time without breaking the other driver. Also these two has to be able to work without the need for the other driver. This MFD device will be used by the drivers, which needs resources from the twl4030 codec like audio and vibra.

* | mfd: Add support for TWL4030/5030 dynamic power switchingAmit Kucheria2009-09-17
|/ | | | | | | | | | | | | The TWL4030/5030 family of multifunction devices allows board-specific control of the the various regulators, clock and reset lines through 'scripts' that are loaded into its memory. This allows for Dynamic Power Switching (DPS). Implement board-independent core support for DPS that is then used by board-specific code to load custom DPS scripts.

* Input: add twl4030_keypad driverDavid Brownell2009-08-28
| | | | | | | | | | | | Add a driver for the keypad controller on TWL4030 family chips. These support up to an 8x8 key matrix. The TWL4030 multifunction chips are mostly used on OMAP3 (or OMAP 2430) based boards.

| * regulator: twl4030 regulatorsDavid Brownell2009-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.

* | memory_accessor: implement the new memory_accessor interface for I2C EEPROMKevin Hilman2009-04-02
|/ | | | | | | | | | | | | | | In the case of at24, the platform code registers a 'setup' callback with the at24_platform_data. When the at24 driver detects an EEPROM, it fills out the read and write functions of the memory_accessor and calls the setup callback passing the memory_accessor struct. The platform code can then use the read/write functions in the memory_accessor struct for reading and writing the EEPROM.
