Merge tag 'regmap-fix-v4.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fixes from Mark Brown: "This is rather too late so it'd be completely understandable if you don't want to pull it at this point, I had thought I'd sent this earlier but it seems I didn't. Everything has been in -next for some time now. The main set of fixes here are mopping up some more issues with MMIO, fixing handling of endianness configuration in DT (which just wasn't working at all) and cases where the register and value endianness are different. There is also a fix for bulk register reads on SPMI" * tag 'regmap-fix-v4.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: spmi: Fix regmap_spmi_ext_read in multi-byte case regmap: mmio: Explicitly say little endian is the defualt in the bus config regmap: mmio: Parse endianness definitions from DT regmap: Fix implicit inclusion of device.h regmap: mmio: Fix value endianness selection regmap: fix documentation to match code
