regulator: Fixes for v6.10
A bunch of fixes that came in during the merge window, Matti found several issues with some of the more complexly configured Rohm regulators and the helpers they use and there were some errors in the specification of tps6594 when regulators are grouped together. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmZPLEoACgkQJNaLcl1U h9DNfQf7B5ppKeMfWEzJKGywWmmzG96AldSvl7rcMyFxdzXjFu/kptGO0tLkJwTs DnlZF6TBooB/RezoHhVgq6nLtJcowQPlbhM3Y4gujzvumZiJ2k2Chsyy+H0YRvkZ kC9Bb2VGk7v5PimZiSugwgc1ZF+AE3LsZyzwWo4d0LZxOE1EyeQQ3SzygoKXtqzF QJxsT6+ynaeYBxVwW+pHztWca8b3o+kqNLauxcWb0J0sPJPu/dl2PIQrKIZBsOWC E34Y8MrrktqPApGE7kVL7dkmofceZI7Qv71aq2UJvRJOhvWP47f2L7nYwYi3kuIH EjioQuqa1Bf7Wms59Q68WLjn4e0ILA== =NeiV -----END PGP SIGNATURE----- Merge tag 'regulator-fix-v6.10-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator fixes from Mark Brown: "A bunch of fixes that came in during the merge window.
