treewide: Fix gdsys mail addresses

2018-03-09T14:23:10+00:00

The @gdsys.cc addresses are supposed to be used for mailing lists.
Switch all occurrences of @gdsys.de mail addresses to their @gdsys.cc
equivalent.

Also, Dirk's address was wrong in one place; fix that as well.

gpio: pca953x_gpio: Support label setting from DT

2018-03-05T15:06:05+00:00

The PCA953x driver uses "gpio@%x_" as the GPIO bank name, where "%x" is
instantiated with the I2C address of the chip. While this works, it
becomes very confusing if a board has multiple PCAs with the same
address on different I2C busses, and it also becomes an issue when a
GPIO's value is to be set via the 'gpio' command, because this command
only ever sets the value of the first device it encounters, leaving the
other devices inaccessible to the command.

As to not break boards that rely on this naming scheme, we introduce a
new device tree string property "label" for the driver. If it exists, it
is used to build a bank name of the form "%s@%x_" (where %x is still
instantiated with the I2C address). If it does not exist, the legacy
labeling scheme is used.

sandbox: Rename 'num-gpios' property to avoid dtc warning

2018-02-18T22:53:32+00:00

At present dtc produces these warnings when compiling sandbox:

arch/sandbox/dts/test.dtb: Warning (gpios_property):
	Could not get phandle node for /base-gpios:num-gpios(cell 0)
arch/sandbox/dts/test.dtb: Warning (gpios_property):
	Missing property '#gpio-cells' in node /reset-ctl or bad phandle
	(referred from /extra-gpios:num-gpios[0])

Both are due to it assuming that the 'num-gpios' property holds a phandle
pointing to a GPIO node.

To avoid these warnings, rename the sandbox property so that it does not
include the string 'gpios'.

bcm283x: Add pinctrl driver

2018-01-28T17:27:32+00:00

The bcm283x family of SoCs have a GPIO controller that also acts as
pinctrl controller.

This patch introduces a new pinctrl driver that can actually properly mux
devices into their device tree defined pin states and is now the primary
owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.

That way whenever a device asks for pinctrl support, it gets it
automatically from the pinctrl driver and GPIO support is still available
in the normal command line phase.
