[PATCH 0/2] qnap-mcu: add ts233 support

[Heiko Stuebner]

For a better return on all the investigating I did into that MCU,
I got myself a 2nd device - the 2-bay TS233 this time.

Add the necessary driver-data and compatible for it to the MCU.

[PATCH 1/2] dt-bindings: mfd: qnap,ts433-mcu: add qnap,ts233-mcu compatible

[Heiko Stuebner]

The same MCU is used on other devices of the series with a slightly
different set of features, like the number of LEDs.

Add a compatible for the MCU used in the TS233 variant.

[PATCH 2/2] mfd: qnap-mcu: add driver data for ts233 variant

[Heiko Stuebner]

Add the TS233 compatible and affiliated driver data to qnap-mcu.
The TS233 is mostly similar to the TS433, except not having any of the
PCIe components, so there are only 2 drives.

The fan pwm-limits from the vendor-configuration also are the same
as for the ts433 variant.
