2013-04-09mfd: support stmpe1801 18 bits enhanced port expanderJean-Nicolas Graux1-0/+3
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.

2012-11-30mfd: stmpe: Get rid of irq_invert_polarityViresh Kumar1-2/+0
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.

2012-11-11mfd: Provide the STMPE driver with its own IRQ domainLee Jones1-0/+2
The STMPE driver is yet another IRQ controller which requires its own IRQ domain. So, we provide it with one.

2012-05-09mfd: Allow for const stmpe keyboard dataLinus Walleij1-1/+1
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.

2012-03-16device.h: audit and cleanup users in main include dirPaul Gortmaker1-1/+3
The <linux/device.h> 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 <paul.gortmaker@windriver.com>

2012-01-09mfd: Add support for stmpe variant 801Viresh Kumar1-0/+1

2012-01-09mfd: Add support for stmpe variant 610Viresh Kumar1-0/+1
STMPE610 is very much like STMPE811, except the number of gpio pins, which is 8 in 811 and 6 in 610. This patch adds support for variant 610. STMPE610 will share most of the code with STMPE811. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-01-09mfd: Separate out STMPE controller and interface specific codeViresh Kumar1-2/+5
Few STMPE controller can have register interface over SPI or I2C. Current implementation only supports I2C and all code is present in a single file stmpe.c. It would be better to separate out I2C interface specific code from controller specific code. Later SPI specific code can be added in a separate file. This patch separates out I2C and controller specific code into separate files, making stmpe.c independent of I2C.

2012-01-09mfd: Add support for irq over gpio pin to stmpeViresh Kumar1-0/+7

2010-10-29gpio: Add bitmask to block requests to unavailable stmpe GPIOsWolfram Sang1-0/+6
GPIOs on these controller are multi-functional. If you decided to use some of them e.g. as input channels for the ADC, you surely don't want those pins to be reassigned as simple GPIOs (which may be triggered even from userspace via 'export'). Same for the touchscreen controller pins. Since knowledge about the hardware is needed to decide which GPIOs to reserve, let this bitmask be inside platform_data and provide some defines to assist potential users.
