From 1b121c6ab548a9af0a27876e9eaa0c654c1dc3e1 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Fri, 29 Sep 2017 00:15:16 +0200 Subject: apalis-tk1: support v1.2 hardware revision Support the V1.2 hardware revision with the following pin muxing changes: Ddc_scl_pv4 and ddc_sda_pv5 previously used as Apalis GPIO3 and GPIO4 are now used as DDC pins. Gen2_i2c_scl_pt5 and gen2_i2c_sda_pt6 previously used as DDC pins are now used as USB power enable signals. Usb_vbus_en0_pn4 and usb_vbus_en1_pn5 previously used as USB power enable signals are now used as GPIO3 and GPIO4. Additionally a new device tree file tegra124-apalis-v1.2-eval.dtb is loaded on V1.2 and later modules and resp. USB power enable signals activated.
