From e75892715db800ee96fe4ac0407b73b57d866a68 Mon Sep 17 00:00:00 2001 From: Florian Tobias Schandinat Date: Sat, 30 Jul 2011 01:25:29 +0000 Subject: [PATCH 01/13] viafb: add auxiliary device management infrastructure This patch adds the basic infrastructure and a few stub drivers for devices that are connected via I2C busses. The infrastructure will be used to replace and extend the support that is scattered throughout viafb. The stub drivers are not very useful yet but they show how the infrastructure works, provide information about the chips integrated into a system and maybe gather some testers as it would be very difficult for a single person to get a sane test environment. The only thing this actually does is probing the I2C busses which will hopefully not cause any regressions.

Schandinat Date: Sun, 26 Feb 2012 10:51:51 +0000 Subject: [PATCH 13/13] viafb: avoid refresh and mode lookup in set_par As check_var already ensures that the mode is valid there is no need to do those expensive lookups here again. The only thing that might change is that the deprecated interface could report slightly different refresh rates due to rounding errors.
