[U-Boot] [PATCH v2 2/3] Tegra114: fdt: Update DT files with I2C info for T114/Dalmore

Tom Warren twarren.nvidia at gmail.com
Thu Feb 7 00:26:47 CET 2013


Note that T114 does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
I2C5 is used to designate the controller intended for power
control (PWR_I2C in the schematics).
