Hello, This is a fully featured series with hopefully all what is needed for upstream acceptance, ie: * A bit of OF cleanup * Full nvmem layout support merging Michael's and my patches * Only the fixes not applying to this series have been kept "un merged" * Support for SL28 VPD and ONIE TLV table layouts * Layouts can be compiled as modules In order for this series to work out-of-the-box it requires to be applied on top of Michael Walle's mtd fixes series (robots running on it, I will provide an immutable tag in the coming days) but for compile-testing only it is not required. Link: https://lore.kernel.org/linux-mtd/20230306125805.678668-1-michael@xxxxxxxx/T/#t So to summarize: * Rob's feedback is welcome on the OF patches * Greg's and Srinivas feedback is welcome on the nvmem patches * If everybody agrees I expect the full series to be applied rather early by Srinivas on top of the -rc he wants. * Once time for the final PR I expect Greg to merge the immutable tag I will provide with Michael's patches before taking these patches from Srinivas. * Rob might request an immutable tag from Greg (at least with the OF patches) if there are any conflicts with his tree. Otherwise if that's foreseen, Rob can also merge the OF patches and produce an immutable tag himself if that's preferred. Indeed, no hurry, but there are other OF cleanup patches which do not have to be in this series which will come later to continue the OF cleanup even further if my understanding of Rob's whishes is right :) Link: https://github.com/miquelraynal/linux-0day/tree/nvmem-layouts-and-of-cleanup Thanks, Miquèl Changes in v2: * Included all initial core nvmem changes. * Merged all the relevant fixes. * Updated the commit logs of the Fixes tag when relevant. * Followed Rob advises to migrate the module related helpers into of/module.c and get the useless helpers out of of_device.c * Added my Signed-off-by when relevant. * Collected tags.
