Such is the case with the Microchip ENCX24J600. Thanks, I've applied this. I'll extend it so that individual devices can do this as well - I've not looked at your driver but it might be that this is a better option than regmap_bus for your driver (but both are supported so meh). Dave, I've tagged the commit and there's a pull request for this below: The following changes since commit 6ff33f3902c3b1c5d0db6b1e2c70b6d76fba357f: Linux 4.3-rc1 (2015-09-12 16:35:56 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git tags/regmap-offload-update-bits for you to fetch changes up to 77792b11409c9270d98e604b4314b85ce886ac7d: regmap: Allow installing custom reg_update_bits function (2015-10-06 16:12:34 +0100) regmap: Allow buses to provide a custom update_bits() operation Some buses provide a native _update_bits() operation which for uncached registers is faster than doing a read/modify/write cycle as it is a single bus transaction. Add support for implementing this to regmap.
