Hello: This series was applied to netdev/net-next.git (master) by David S. Miller [off-list ref]: On Sun, 13 Feb 2022 11:12:50 -0800 you wrote:
Ocelot loops over memory regions to gather stats on different ports. These regions are mostly continuous, and are ordered. This patch set uses that information to break the stats reads into regions that can get read in bulk. The motiviation is for general cleanup, but also for SPI. Performing two back-to-back reads on a SPI bus require toggling the CS line, holding, re-toggling the CS line, sending 3 address bytes, sending N padding bytes, then actually performing the read. Bulk reads could reduce almost all of that overhead, but require that the reads are performed via regmap_bulk_read. [...]
