kernel/include/linux/mfd/stmfx.h, branch linux-5.14.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.14.y2020-05-26T09:51:21Zmfd: stmfx: Disable IRQ in suspend to avoid spurious interrupt2020-05-26T09:51:21ZAmelie Delaunayamelie.delaunay@st.com2020-04-22T09:08:33Zurn:sha1:97eda5dcc2cde5dcc778bef7a9344db3b6bf8ef5
When STMFX supply is stopped, spurious interrupt can occur. To avoid that,
disable the interrupt in suspend before disabling the regulator and
re-enable it at the end of resume.

STMicroelectronics Multi-Function eXpander (STMFX) is a slave controller
using I2C for communication with the main MCU. Main features are:
- 16 fast GPIOs individually configurable in input/output
- 8 alternate GPIOs individually configurable in input/output when other
STMFX functions are not used
- Main MCU IDD measurement
- Resistive touchscreen controller
