Subject: [PATCH 3/5] i2c: tegra: Add Tegra264 support
Date: Wed, 8 Jan 2025 16:36:18 +0530	[thread overview]
Message-ID: <20250108110620.86900-4-kkartik@nvidia.com> (raw)
In-Reply-To: <20250108110620.86900-1-kkartik@nvidia.com>

From: Akhil R <akhilrajeev@nvidia.com>

Add support for Tegra264 SoC which supports 17 generic I2C controllers,
two of which are in the AON (always-on) partition of the SoC. Tegra264
I2C supports all the features supported by Tegra194 I2C controllers.
