This patch generalizes the module_platform_driver macro and introduces a new module_driver macro. The module_driver macro takes a driver name, a register and a unregister function for this driver type. Using these it construct the module init and exit sections which register and unregister the driver. Since such init/exit sections are commonly found in drivers this macro can be used to eliminate a lot of boilerplate code. The macro is not intended to be used by driver modules directly, instead it should be used to generate bus specific macros for registering drivers like the module_platform_driver macro.

2012-04-15regmap: implement register stridingStephen Warren
regmap_config.reg_stride is introduced. All extant register addresses are a multiple of this value. Users of serial-oriented regmap busses will typically set this to 1. Users of the MMIO regmap bus will typically set this based on the value size of their registers, in bytes, so 4 for a 32-bit register. Throughout the regmap code, actual register addresses are used. Wherever the register address is used to index some array of values, the address is divided by the stride to determine the index, or vice-versa. Error- checking is added to all entry-points for register address data to ensure that register addresses actually satisfy the specified stride. The MMIO bus ensures that the specified stride is large enough for the register size.

2012-04-15regmap: introduce explicit bus_context for bus callbacksStephen Warren
The only context needed by I2C and SPI bus definitions is the device itself; this can be converted to an i2c_client or spi_device in order to perform IO on the device. However, other bus types may need more context in order to perform IO. Enable this by having regmap_init accept a bus_context parameter, and pass this to all bus callbacks. The existing callbacks simply pass the struct device here. Future bus types may pass something else.

2012-04-03regulator: fixed: Support for open drain gpio pinLaxman Dewangan
Adding flag on fixed regulator board configuration structure to specify whether gpio is open drain type or not. Passing this information to gpio library when requesting gpio so that gpio driver can set the pin state accordingly, for open drain type: - Pin can be set HIGH as setting as input, PULL UP on pin make this as HIGH. - Pin can be set LOW as setting it as output and drive to LOW. The non-open drain pin can be set HIGH/LOW by setting it to output and driving it to HIGH/LOW.
