[PATCH 0/2][SRU][J] Add ODM driver gpio-m058ssan

[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/2045386

[ 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/i2c/devices/i2c-0/new_device

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.
