Subject: [PATCH 2/3] Add gpio-m058ssan kernel driver
BugLink: https:/
[ Impact ]
gpio-m058ssan driver needed for ODM partner
[ Test Plan ]
Connect the loopback GPIO connector to the ReliaCOR-40-13 system and connect the power supply of the GPIO connector.
insert the "m058ssan" module:
modprobe m058ssan
create GPIOchip:
echo "m058ssan 0x40" > /sys/bus/
get the GPIO chip base and export 16 GPIOs. The former 8 are GPOs , the latter 8 are GPIs.
Set and reset all of the GPOs one at a time and check that the corresponding GPI is set and reset accordingly.
[ Where problems could occur ]
Make sure that the power supply of the GPIO connector is correctly connected, otherwise the GPI will always report 0.
Events could occur on the i2c bus communication that may cause miss-behavior of the driver.
