From 996588521a2240397b4a89e5ad5f5708f930dbc8 Mon Sep 17 00:00:00 2001 From: Uwe Poeche Date: Tue, 5 Nov 2019 15:44:42 +0100 Subject: src/mainboard/siemens: Use PTN3460 chip driver This patch replaces and cleans up the redundant PTN3460 driver files in /mainboard/siemens directories by using the now available driver in src/drivers/i2c/ptn3460 and providing mainboard specific functions to the driver. TEST=Display is working on Siemens mainboards (e.g. mc_tcu3, mc_apl1, ...).
