x86: ich6_gpio: Convert to use proper DM API

2016-02-05T04:47:21+00:00

At present this GPIO driver still uses the legacy PCI API. Now that
we have proper PCH drivers we can use those to obtain the information
we need. While the device tree has nodes for the GPIO peripheral it is
not in the right place. It should be on the PCI bus as a sub-peripheral
of the PCH device.

Update the device tree files to show the GPIO controller within the PCH,
so that PCI access works as expected. This also adds '#address-cells'
and '#size-cells' to the PCH node.

dm: vybrid_gpio: Drop legacy code

2016-02-02T20:36:10+00:00

All boards using this driver are with device tree support,
hence drop the legacy code in driver to have a pure DT solution.

drivers: gpio: add driver for Microchip PIC32 GPIO controller.

2016-02-01T21:14:00+00:00

In PIC32 GPIO controller is part of PIC32 pin controller.
PIC32 has ten independently programmable ports and each with multiple pins.
Each of these pins can be configured and used as GPIO, provided they
are not in use for other peripherals.

bug.h: move BUILD_BUG_* defines to include/linux/bug.h

2016-01-25T15:39:59+00:00

BUILD_BUG_* macros have been defined in several headers.  It would
be nice to collect them in include/linux/bug.h like Linux.

This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.

I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot.  I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

rockchip: gpio: Implement the get_function() method

2016-01-22T03:42:35+00:00

Provide this method so that 'gpio status' works fully. It now shows
whether a pin is used for input, output or some other function.

This function should return 0 or 1, not a mask. Fix it.

dm: gpio: Allow the uclass to work without printf()

2016-01-21T02:06:22+00:00

For SPL we don't really need sprintf() and with tiny-printf this is not
available. Allow this to be dropped in SPL when using tiny-printf.

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21+00:00

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.
