[PATCH 3/4] ARM: dts: Add support of STid127 Soc.
Patrice CHOTARD
patrice.chotard at st.com
Thu Jan 30 09:55:43 EST 2014
From: Alexandre TORGUE <alexandre.torgue at st.com>
The STid127 integrates all harware components to function as a cable modem
or, in combination with a back end device, as a Gateway set top boxe.
Supported devices:
-UART0
-UART2
