Subject: [PATCH v4 0/9] Introduce STMFX I2C Multi-Function eXpander
Date: Wed, 27 Feb 2019 10:34:45 +0100 [thread overview]
Message-ID: <1551260094-32570-1-git-send-email-amelie.delaunay@st.com> (raw)
This series adds support for STMicroelectronics Multi-Function eXpander
(STMFX), used on some STM32 discovery and evaluation boards.
STMFX is an STM32L152 slave controller whose firmware embeds the following
features:
- I/O expander (16 GPIOs + 8 extra if the other features are not enabled),
- resistive touchscreen controller,
- IDD measurement.
I2C stuff and chip initialization is based on an MFD parent driver, which
registers STMFX features MFD children.
---
Changes in v4:
- mfd: move registers #define into the header
- mfd: merge stmfx and stmfx_ddata structures into one stmfx structure
- mfd: change stmfx_chip_init/exit and stmfx_irq_init/exit args: use
i2c_client struct and i2c_get_clientdata
- mfd: fix typos
- mfd: add MFD cells for IDD and TS features
- pinctrl: rework registers #define
- dts: add STMFX support on stm32mp157c-ev1
Changes in v3:
- fix MFD interrupt bindings
- fix drivers/mfd/stmfx.c:103:8: warning: 'mask' may be used uninitialized
in this function
Changes in v2:
- move to MFD parent driver for i2c stuff and chip initialization
- improve regmap configuration
- take advantage of the use of gpio-ranges
