Javier Martinez Canillas 459b81808f gpio: kempld: use BIT() macro instead of shifting bits
Using the BIT() macro instead of shifting bits
makes the code less error prone and also more readable.

Make the module alias match the platform device name, so gpio-kempld module
should now autoload correctly.

Linus Walleij 9fb1f39eb2 gpio/pinctrl: make gpio_chip members typed boolean
This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

Brunner Michael 2e7f612264 gpio: Fix bit masking in Kontron PLD GPIO driver
This patch fixes the bit masking within the GPIO driver. The masking is
basically done twice which causes the wrong GPIOs to be addressed.

Michael Brunner 81e9df2c94 gpio: Fix platform driver name in Kontron PLD GPIO driver
This patch changes the driver name to be consistent with the name that
is registered as cell name in the MFD driver. Otherwise the driver won't
load.

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.
