i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLING

2012-05-30T08:55:34+00:00

Since there are uses for I2C_M_NOSTART which are much more sensible and
standard than most of the protocol mangling functionality (the main one
being gather writes to devices where something like a register address
needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART
for this feature and update all the users to use it.

Also strengthen the disrecommendation of the protocol mangling while we're
at it.

In the case of regmap-i2c we remove the requirement for mangling as
I2C_M_NOSTART is the only mangling feature which is being used.

regmap: introduce explicit bus_context for bus callbacks

2012-04-06T09:47:34+00:00

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.

regmap: Implement managed regmap_init()

2012-01-30T21:06:43+00:00

Save error handling and unwinding code in drivers by providing managed
versions of the regmap init functions, simplifying usage.

regmap: Remove redundant owner field from the bus type struct

2011-09-05T17:57:04+00:00

No longer used as users link directly with the bus types so the core
module infrastructure does refcounting for us.

regmap: Specify a module license

2011-08-12T01:42:02+00:00

CONFIG_REGMAP_I2C/SPI are set to m when selected by a tristate config
option that's set to m. The regmap modules don't specify a license, so
fail to link to regmap_init at load time, since that is EXPORT_SYMBOL_GPL.
Fix this by specifying a license for the regmap modules.

regmap: Remove unused type and list fields from bus interface

2011-08-09T15:26:38+00:00

We no longer enumerate the bus types, we rely on the driver telling us
this on init.
