From e126edec184ea3049cc1f8b652c6eeb06aa65fda Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 15 Feb 2016 05:24:51 +0000 Subject: [PATCH] regmap: add regmap_fields_update_bits_base() This patch adds new regmap_fields_update_bits_base() which is using regmap_update_bits_base(). Current regmap_fields_xxx() can be merged into it by macro.
