Subject: [U-Boot] [PATCH v3 2/3] Tegra114: fdt: Update DT files with I2C info for T114/Dalmore
Date: Fri,  8 Feb 2013 10:25:31 -0700	[thread overview]
Message-ID: <1360344332-14664-3-git-send-email-twarren@nvidia.com> (raw)
In-Reply-To: <1360344332-14664-1-git-send-email-twarren@nvidia.com>

T114, like T30, 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). PWR_I2C is set to 400KHz.

---
v2: Match dts files with kernel files, remove unused apdma node
v3:
- moved aliases to dtsi file as per StephenW
- removed tegra30-car & tegra20-i2c compatible strings
- changed I2C5 (PWR_I2C) clock to 400MHz
