2012-04-16drivercore: Generalize module_platform_driverLars-Peter Clausen
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: allow regmap instances to be namedStephen Warren
Some devices have multiple separate register regions. Logically, one regmap would be created per region. One issue that prevents this is that each instance will attempt to create the same debugfs files. Avoid this by allowing regmaps to be named, and use the name to construct the debugfs directory name.

2012-04-15regmap: add MMIO bus supportStephen Warren
This is a basic memory-mapped-IO bus for regmap. It has the following features and limitations: * Registers themselves may be 8, 16, 32, or 64-bit. 64-bit is only supported on 64-bit platforms. * Register offsets are limited to precisely 32-bit. * IO is performed using readl/writel, with no provision for using the __raw_readl or readl_relaxed variants.

2012-04-15regmap: introduce fast_io busses, and use a spinlock for themStephen Warren
Some bus types have very fast IO. For these, acquiring a mutex for every IO operation is a significant overhead. Allow busses to indicate their IO is fast, and enhance regmap to use a spinlock for those busses.

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.

2012-04-15regmap: Allow drivers to sync only part of the register cacheMark Brown
Provide a regcache_sync_region() operation which allows drivers to write only part of the cache back to the hardware. This is intended for use in cases like power domains or DSP memories where part of the device register map may be reset without fully resetting the device. Fully supporting these devices is likely to require additional work to make specific regions of the register map cache only while they are in reset, but this is enough for most devices.
