0b9483bf7f mfd: adp5585: Drop useless return statement 
In adp5585_reset_ev_parse(), when parsing the
adi,reset-pulse-width-us property, we were returning in case it was
found and valid. No point in doing that as we'll be returning anyways
after the exiting the property scope. And it could actually lead to bugs
if new properties happen to added after this one.

81a2c31257 mfd: simple-mfd-i2c: Add compatible strings for Layerscape QIXIS FPGA 
The QIXIS FPGA found on Layerscape boards such as LX2160AQDS, LS1028AQDS
etc deals with power-on-reset timing, muxing etc. Use the simple-mfd-i2c
as its core driver by adding its compatible string (already found in
some dt files). By using the simple-mfd-i2c driver, any child device
will have access to the i2c regmap created by it.

017bdcdb3a MAINTAINERS: Adjust file entry in LOONGSON SECURITY ENGINE DRIVERS 
Commit 5c83b07df9 ("tpm: Add a driver for Loongson TPM device") adds a
driver at drivers/char/tpm/tpm_loongson.c, and commit 74fddd5fba
("MAINTAINERS: Add entry for Loongson Security Engine drivers") adds a new
section LOONGSON SECURITY ENGINE DRIVERS intending to refer to that driver.
It however adds the entry drivers/char/tpm_loongson.c; note that it misses
the tpm subdirectory.

Adjust the entry to refer to the intended file.

a727bc0588 tpm: loongson: Add bufsiz parameter to tpm_loongson_send() 
Commit 5c83b07df9 ("tpm: Add a driver for Loongson TPM device") has a
semantic conflict with commit 07d8004d6f ("tpm: add bufsiz parameter
in the .send callback"), as the former change was developed against a
tree without the latter change. This results in a build error:

1efbee6852 mfd: vexpress-sysreg: Check the return value of devm_gpiochip_add_data() 
Commit 974cc7b934 ("mfd: vexpress: Define the device as MFD cells")
removed the return value check from the call to gpiochip_add_data() (or
rather gpiochip_add() back then and later converted to devres) with no
explanation. This function however can still fail, so check the return
value and bail-out if it does.

2215a87b02 mfd: tps6594: Add board power-off support 
Add a system level power-off handler if the "system-power-controller"
flag is set for this device in the device tree.

A power-off request is triggered by writing the TRIGGER_I2C_0 bit (which
is actually just a convention and really depends on the freely
programmable FSM).

170031ff27 input: tps6594-pwrbutton: Add power button functionality 
TPS6594 defines two interrupts for the power button one for push and
one for release.

This driver is very simple in that it maps the push interrupt to a key
input and the release interrupt to a key release.

Loongson Security Engine supports random number generation, hash,
symmetric encryption and asymmetric encryption. Based on these
encryption functions, TPM2 have been implemented in the Loongson
Security Engine firmware. This driver is responsible for copying data
into the memory visible to the firmware and receiving data from the
firmware.
