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

2016-02-01T21:14:00Z

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

2016-01-25T15:39:59Z

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

2016-01-22T03:42:35Z

Provide this method so that 'gpio status' works fully. It now shows whether a pin is used for input, output or some other function. Signed-off-by: Simon Glass

rockchip: gpio: Read the GPIO value correctly

2016-01-22T03:42:35Z

This function should return 0 or 1, not a mask. Fix it. Signed-off-by: Simon Glass

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

2016-01-21T02:06:22Z

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. Signed-off-by: Simon Glass

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21Z

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. Signed-off-by: Tom Rini

gpio: mxs: add name_to_gpio() function

2016-01-07T16:54:16Z

Override the default name_to_gpio() function with one that accepts strings of the form bank:pin. If a colon is present in the provided name, it behaves like the default version. This lets the "gpio" command work with sane names rather than requiring the user to enter the bank/pin composite in decimal. Signed-off-by: Mans Rullgard Reviewed-by: Stefano Babic
