The patch
regmap: slimbus: add support to multi read/write
has been applied to the regmap tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

SLIMbus supports upto 16 bytes in value management messages, so add support to read/writes upto 16 bytes.
This also removes redundant single register reg_read/reg_write.
Also useful for paged register access on SLIMbus interfaced codecs.
