GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage. This branch does the work to completely eliminate GENERIC_GPIO. However, it is not trivial to just create a branch to remove it. Over the course of the v3.9 cycle more code referencing GENERIC_GPIO has been added to linux-next that conflicts with this branch. The following must be done to resolve the conflicts when merging this branch into mainline: * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be replaced with CONFIG_GPIOLIB * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese documentation. * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB * definitions of the option in architecture Kconfig code should be deleted. Stephen has 3 merge fixup patches[1] that do the above. They are currently applicable on mainline as of May 2nd.

If you say yes to this option, support will be included for an

I2C multimaster arbitration scheme using GPIOs and a challenge &

response mechanism where masters have to claim the bus by asserting
|
|
a GPIO.
|

This driver can also be built as a module. If so, the module

will be called i2c-arb-gpio-challenge.

If you say yes to this option, support will be included for a

I2C busses connected through a MUX, which is controlled

If you say yes to this option, support will be included for an I2C
|
|
multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
|
|
This is useful for SoCs whose I2C module's signals can be routed to
|
|
different sets of pins at run-time.
|
|
|
|
This driver can also be built as a module. If so, the module will be
|
|
called pinctrl-i2cmux.
