From fa28e067c3b8af96c79c060e163b1387c172ae75 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Sat, 9 Feb 2008 23:24:08 +0100 Subject: [PATCH] x86: GEODE: MFGPT: drop module owner usage from MFGPT API We had planned to use the 'owner' field for allowing re-allocation of MFGPTs; however, doing it by module owner name isn't flexible enough. So, drop this for now. If it turns out that we need timers in modules, we'll need to come up with a scheme that matches the write-once fields of the MFGPTx_SETUP register, and drops ponies from the sky.
