[PATCH v2 0/2] Allow syscon to use spinlocks with regmap fast_io
From: AngeloGioacchino Del Regno
Date: Mon Apr 04 2022 - 04:47:55 EST
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.

mfd: syscon: Allow using spinlocks with regmap fast_io
dt-bindings: mfd: syscon: Add support for regmap fast-io
