This series adds support for enabling the regmap's fast_io configuration option for SoCs featuring very fast MMIO operations, for which mutexes are introducing a lot of overhead / latency. This has been tested locally on some MediaTek Chromebooks (but, of course, that requires devicetree patches that are not included in this series). Changes in v2: - Reworded dt-bindings fast-io description to remove references to regmap, making it generic, as per Krzysztof's suggestion.
