From 0f5b461b9bf028c5ce8fd22e8bd45d8c1234e2fd Mon Sep 17 00:00:00 2001 From: Liam Beguin Date: Tue, 14 Mar 2017 11:24:45 -0400 Subject: i2c: lpc32xx: Force consistent bus numbering Normally, this would probably be done by adding devicetree aliases to the main dtsi file for the lpc32xx and using bus->req_seq instead. Since we want to have consistent i2c numbering, we cannot force the bus->req_seq because. If for instance we have 3 buses numbered from 0 to 2 with i2c0 enabled, i2c1 disabled and i2c2 enabled; i2c2 can be selected using 'i2c dev 1' and 'i2c dev 2' commands because a bus can be probed using req_seq or seq interchangeably.
