No need to do the irq_chip->irq_mask() if it already masked.
BTW, unconditionally do the irq_chip->irq_mask() will also bring issues

Add the possibility to add architecture specific vDSO

Should this go to Documentation, not a changelog?

Hi Bingbu,
Thank you for the patch.

GPIO recovery has been added already for some I2C bus drivers, such as
imx, pxa and at91. These drivers use similar bindings and have more or
less the same code for recovery. For this reason, we aim to move the
GPIO bus recovery implementation to the I2C core so that other drivers
can benefit from
The I2C GPIO bus recovery properties consist of two GPIOS and one extra
pinctrl state ("gpio" or "recovery"). "recovery" pinctrl state is
considered deprecated and "gpio" should be used instead.
Not all are mandatory for recovery.

Multiple I2C bus drivers use similar bindings to obtain information needed
for I2C recovery. For example, for platforms using device-tree, the
properties look something like this:
&i2c {
...
pinctrl-names = "default", "gpio";
pinctrl-0 = <&pinctrl_i2c_default>;
pinc
Even if I2C bus GPIO recovery is optional, devm_gpiod_get() can return
-EPROBE_DEFER, so we should at least treat that. This ends up with
i2c_register_adapter() to be able to return -EPROBE_DEFER.

The burst read function (BRF) provides a method for reading a batch of
data (status, temperature, gyroscopes, accelerometers, timestamp/data
counter and CRC code), which does not require a stall time between each
16-bit sgment and only requires on command on the DIN line to init
