mfd: Add STMPE1600 support

2016-08-10T08:25:18+00:00

STMPE1600 is a 16-bit port expander. Datasheet is available here : http://www2.st.com/content/st_com/en/products/interfaces-and-transceivers/ i-o-expanders-and-level-translators/i-o-expanders/stmpe1600.html Signed-off-by: Amelie DELAUNAY Signed-off-by: Patrice Chotard Acked-by: Linus Walleij Signed-off-by: Lee Jones

mfd: stmpe: Rework registers access

2016-08-10T08:24:39+00:00

this update allows to use registers map as following : regs[reg_index + offset] instead of regs[reg_index] + offset This makes code clearer and will facilitate the addition of STMPE1600 on which LSB and MSB registers are respectively located at addr and addr + 1. Despite for all others STMPE variant, LSB and MSB registers are respectively located in reverse order at addr + 1 and addr. For variant which have 3 registers's bank, we use LSB,CSB and MSB indexes which contains respectively LSB (or LOW), CSB (or MID) and MSB (or HIGH) register addresses (STMPE1801/STMPE24xx). For variant which have 2 registers's bank, we use LSB and CSB indexes only. In this case the CSB index contains the MSB regs address (STMPE 1601).

mfd: stmpe: Add STMPE_IDX_SYS_CTRL/2 enum

2016-08-10T08:23:25+00:00

As STMPE1801/1601/24xx has a SYS_CTRL register and STMPE1601/2403 has even a SYS_CTRL2 register, add STMPE_IDX_SYS_CTRL/2 and update driver code accordingly This update prepares the ground for not yet supported STMPE1600 which share similar REG_SYS_CTRL register.

mfd: stmpe: Move platform data into MFD driver

2016-06-29T09:15:51+00:00

The STMPE platform data is only populated from the device tree in all existing users, so push the struct and make the OF case the norm. Signed-off-by: Linus Walleij Signed-off-by: Lee Jones

Input: stmpe-ts - enforce device tree only mode

2015-05-26T21:16:08+00:00

The STMPE MFD is only used with device tree configured systems (and STMPE MFD core depends on OF), so force the configuration to come from device tree only. Tested-by: Heiner Kallweit Reviewed-by: Marek Vasut Acked-by: Lee Jones Signed-off-by: Dmitry Torokhov

gpio: stmpe: enforce device tree only mode

2015-01-20T10:03:22+00:00

Require that device tree be used with STMPE (all platforms use this) and enforce OF_GPIO, then delete the platform data. Signed-off-by: Linus Walleij

Input: stmpe - enforce device tree only mode

2014-12-16T05:46:12+00:00

The STMPE keypad controller is only used with device tree configured systems, so force the configuration to come from device tree only, and now actually get the rows and cols from the device tree too. Signed-off-by: Linus Walleij Acked-by: Lee Jones Signed-off-by: Dmitry Torokhov

mfd: stmpe: add pull up/down register offsets for STMPE

2014-12-16T05:46:11+00:00

This adds the register offsets for pull up/down for the STMPE 1601, 1801 and 24xx expanders. This is used to bias GPIO lines and keypad lines. Signed-off-by: Linus Walleij Acked-by: Lee Jones Signed-off-by: Dmitry Torokhov

mfd: stmpe: root out static GPIO and IRQ assignments

2014-05-23T08:41:01+00:00

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

2014-05-09T09:51:12+00:00

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
