[U-Boot] [PATCH v1] apalis-tk1: support v1.2 hardware revision

Igor Opaniuk igor.opaniuk at gmail.com
Fri Aug 9 10:21:46 UTC 2019


From: Marcel Ziswiler <marcel.ziswiler at 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.
