The AST2600 SoC hardware includes a set of i3c controllers, based on the designware i3c core, plus some global registers for SoC integration. This series adds support for these i3c controllers, through the existing dw i3c master controller driver, by adding a set of platform-specific hooks to handle the global register configuration. This also gives us a way to add any future hardware-specific behaviours. We also need a DT binding to describe the ast2600-specific hardware. Since this involves new (mandatory) properties, I have added this as a separate binding rather than add a new compat string to the dw binding. The dt-binding example depends on a prior submission to the dt binding headers: https://lore.kernel.org/linux-devicetree/cover.1676294433.git.jk@xxxxxxxxxxxxxxxxxxxx/ Full support for the global regmap will land with this queued mfd change: https://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git/commit/?id=cf2271843de835839e91c5c036492a87085af756 Of course, any queries/comments/etc are most welcome.
