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

GPIO based I2C multiplexer. This driver provides access to

I2C busses connected through a MUX, which is controlled

through GPIO pins.

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

will be called i2c-mux-gpio.

help
|

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.
