From: Jonathan Neuschäfer Date: Sat, 8 Oct 2022 12:59:23 +0000 (+0200) Subject: i2c: npcm7xx: Group bank 0/1 registers together for readability X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a826b6e9e467ed378a2c50c4a03cb863ab681198;p=linux.git i2c: npcm7xx: Group bank 0/1 registers together for readability The unlabelled registers NPCM_I2CCTL4 to NPCM_I2CSCLHT overlap with the bank 1 registers below, and they are accessed after selecting bank 0, so they clearly belong to bank 0. Move them together with the other bank 0 registers, and move the unrelated definition of npcm_i2caddr down to keep the banked registers in one piece.
