Hi!
Here's a new version of serdev multiplexing support. Thanks to everybody who
commented; I think I have included all non-optional suggestions. :)
Changes are manifold, please refer to the changelog below.
This version drops "mux: include compiler.h from mux/consumer.h",
which is on its way upstream by now.

Changes since RFC v2:
- parity: use an enum instead of the traditional enable/odd flags
- mux: include it in the serdev core, remove option
- mux: add "select MULTIPLEXER" to Kconfig
- serdev: use device "reg" node as serdev_device::nr
- mux: check if device has an of_node before trying to register mux
- serdev: remove check for !serdev->ops in,
serdev_controller_write_wakeup(), it is not needed
- max9260: replace register numbers, magic protocol bytes and device ID with
macros
- max9260: use enum instead of macros for the rx_state
- max9260: use wait_event_timeout() instead of
wait_event_interruptible_timeout()
- max9260: pass all parameters for max9260_transact() as arguments
- max9260: add "max9260_" prefix to max9260_wait_for_transaction()
- max9260: return -ENODEV instead of -EINVAL if the device does not respond
correctly
- max9260: change a number of length-bearing variables to size_t
- dt: number max9260 devices according to their "reg" node
Ulrich Hecht (6):
serdev: add method to set parity
serdev: add multiplexer support
serial: core: support deferring serdev controller registration
max9260: add driver for i2c over GMSL passthrough
ARM: dts: blanche: add SCIF1 and MAX9260 deserializer
dt-bindings: slave-device: add reg property
