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 >From e76ad18b56775aa20c0fb8e6203fae2aaee57e5c Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 6 Jul 2018 16:05:27 +0100 Subject: [PATCH] regmap: slimbus: add support to multi read/write 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.
