mfd: stmpe: root out static GPIO and IRQ assignments

2014-05-23T08:41:01Z

The only platform using the STMPE expander now boots from device tree using all-dynamic GPIO and IRQ number assignments, so remove the mechanism to pass this from the device tree entirely. Signed-off-by: Linus Walleij

mfd: stmpe: add optional regulators

2014-05-09T09:51:12Z

The STMPE has VCC and VIO supply lines, and sometimes (as on Ux500) this comes from a software-controlled regulator. Make it possible to supply the STMPE with power from these regulators. Signed-off-by: Linus Walleij

mfd: support stmpe1801 18 bits enhanced port expander

2013-04-09T12:15:58Z

Provides support for 1801 variant of stmpe gpio port expanders. This chip has 18 gpios configurable as GPI, GPO, keypad matrix, special key or dedicated key function. Note that special/dedicated key function is not supported yet. Signed-off-by: Jean-Nicolas Graux Acked-by: Linus Walleij Signed-off-by: Samuel Ortiz

mfd: stmpe: Get rid of irq_invert_polarity

2012-11-30T10:54:51Z

Since the very first patch, stmpe core driver is using irq_invert_polarity as part of platform data. But, nobody is actually using it in kernel till now. Also, this is not something part of hardware specs, but is included to cater some board mistakes or quirks. So, better get rid of it.

mfd: Provide the STMPE driver with its own IRQ domain

2012-11-11T22:35:03Z

The STMPE driver is yet another IRQ controller which requires its own IRQ domain. So, we provide it with one. Acked-by: Arnd Bergmann Acked-by: Linus Walleij Signed-off-by: Lee Jones Signed-off-by: Samuel Ortiz

mfd: Allow for const stmpe keyboard data

2012-05-09T15:20:29Z

Since it's not like we will re-arrange the keys at run-time, it seems proper to allow the keymap data to be const. This solves a compilation warning in ux500. Cc: Dmitry Torokhov Signed-off-by: Linus Walleij Signed-off-by: Samuel Ortiz

device.h: audit and cleanup users in main include dir

2012-03-16T14:38:24Z

The header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker
