From 8019ff6cfc0440415fcfb6352c58c3951e6ab053 Mon Sep 17 00:00:00 2001 From: Nariman Poushin Date: Thu, 16 Jul 2015 16:36:21 +0100 Subject: regmap: Use reg_sequence for multi_reg_write / register_patch Separate the functionality using sequences of register writes from the functions that take register defaults. This change renames the arguments in order to support the extension of reg_sequence to take an optional delay to be applied after any given register in a sequence is written. This avoids adding an int to all register defaults, which could substantially increase memory usage for regmaps with large default tables. This also updates all the clients of multi_reg_write/register_patch.
