[PATCH 0/2] gpio: realtek-otto: Add RTL9311B support

[Joshua Scott]

The RTL9311B is an Arm-based Realtek switch SoC with the same GPIO
controller as the MIPS-based Otto SoCs, laid out like the RTL9310's.
This series adds a compatible for it and lets the driver be built for
ARCH_REALTEK.

Tested on an RTL9311B board with an Infineon SLM9670 TPM on a spi-gpio
bus using GPIO3-6: the TPM probes with tpm_tis_spi and responds to PCR
reads and TPM2_GetRandom.

These patches were prepared with the help of Claude Code
(claude-opus-5-5), which drafted the code changes and changelogs. I
reviewed them and tested them on hardware.
