mfd: stmpe: Make stmpe_remove() return void

2021-11-05T14:40:26+00:00

Up to now stmpe_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

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: 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: Use generic bit mask name

2016-08-10T08:24:29+00:00

In order to prepare the ground to STMPE1600, as STMPE1600's SYS_CTRL register has the same layout as STMPE801 variant, unify STMPExxx_REG_SYS_CTRL_RESET/INT_EN/INT_HI bit masks to more generic STMPE_SYS_CTRL_RESET/INT_EN/INT_HI Signed-off-by: Patrice Chotard Signed-off-by: Lee Jones

mfd: stmpe: Add reset support for all STMPE variant

2016-08-10T08:23:33+00:00

Reset was only implemented for STMPE1801 variant despite all variant have a SOFT_RESET bit. For STMPE2401/2403/801/1601/1801 SOFT_RESET bit is bit 7 of SYS_CTRL register. For STMPE610/811 (which have the same variant id) SOFT_RESET bit is bit 1 of SYS_CTRL register. Signed-off-by: Patrice Chotard Acked-by: Linus Walleij Signed-off-by: Lee Jones

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: 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
