Subject: [U-Boot] [PATCH 2/3] Tegra30: fdt: Update DT files with I2C info for T30/Cardhu
Date: Fri, 21 Dec 2012 17:16:38 -0700 [thread overview]
Message-ID: <1356135399-28339-3-git-send-email-twarren@nvidia.com> (raw)
In-Reply-To: <1356135399-28339-1-git-send-email-twarren@nvidia.com>
Note that T30 does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
DVC_I2C is still used to designate the controller intended for
power control (PWR_I2C in the schematics). On Cardhu, it's used
to access the PMU and EEPROM, as well as the audio codec, temp
sensor, and fuel gauge devices from the OS.
