Hi, this is continuation for the MMIO accessor rewrite and cleanup. I am currently running nv28 with these patches applied, but I cannot test on PPC. Please, review and comment. If the direction is good, I'll do the same to INSTANCE_{RD,WR} as I did for nv_{rd,wr}32, and change PRAMIN from drm_local_map to simple ioremap. Can the same be done for channel specific mappings, that is

Hi, Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at kernel.org/ 1. Constify also ioreadX_rep() and mmio_insX(), 2. Squash lib+alpha+powerpc+parisc+sh into one patch for bisectability, 3. Add acks and reviews, 4. Re-order patches so all optional driver changes are at the end. Description =========== The ioread8/16/32() and others have

Hi, Multiple architectures are affected in the first patch and all further patches depend on the first. Maybe this could go in through Andrew Morton's tree? Changes since v2 ================ 1. Drop all non-essential patches (cleanups), 2. Update also drivers/sh/clk/cpg.c . Changes since v1 ================ https://lore.kernel.org/lkml/1578415992-24054-1-git-send-email-krzk at

Hi, The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not. It seems there is nothing really stopping all of them to take pointer to const. Patchset was really tested on all affected architectures. Build testing is in progress - I hope auto-builders will point any issues. Todo ==== Convert also string versions (ioread16_rep()
