treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 464

2019-06-19T15:09:10+00:00

Based on 1 normalized pattern(s): license terms gnu general public license version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 11 file(s).

mfd: stmpe: Preparations for STMPE ADC driver

2019-01-16T12:36:12+00:00

This prepares the MFD for the STMPE ADC driver. This commit introduces devicetree settings that are used by the ADC and adds an init function. Common ADC settings that are shared with the touchscreen driver can now reside in the overlying MFD.

mfd: stmpe: Move ADC related defines to MFD header

2019-01-16T12:35:41+00:00

Move defines that are ADC related to the header of the overlying MFD, so they can be used from multiple sub-devices. Signed-off-by: Philippe Schenker Acked-by: Dmitry Torokhov Signed-off-by: Lee Jones

mfd: Add STMPE1600 support

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

STMPE1600 is a 16-bit port expander.

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
