[U-Boot] [PATCH v3 09/10] apalis-tk1: support v1.2 hardware revision

5 Aug 2019

From: Marcel Ziswiler marcel.ziswiler@toradex.com
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.
