Subject: [PATCH 0/2] Allow syscon to use spinlocks with regmap fast_io

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).

AngeloGioacchino Del Regno (2):
  mfd: syscon: Allow using spinlocks with regmap fast_io
  dt-bindings: mfd: syscon: Add support for regmap fast-io
