The Tegra 3 Interface Design Guide states the same 133 MHz.

[PATCH v2 0/6] Add support for Tegra GMI bus controller

[Mirza Krak]

From: Mirza Krak <mirza.krak@gmail.com>

Hi.

This is a follow up to my previous RFC to add support for Tegra GMI bus
controller.

I have tested this series on a Tegra30 using a Colibri T30 SOM on a custom
carrier board which has multiple CAN controllers (SJA1000) connected to the
GMI bus.

I have rebased on top of latest tegra/for-next in V2. Also see individual
patches for changes in V2.

See below links for previous discussions.

[PATCH v2 2/6] clk: tegra: add TEGRA30_CLK_NOR to init table

[Mirza Krak]

From: Mirza Krak <mirza.krak-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Add TEGRA30_CLK_NOR to init table and set default rate to 127 MHz which
is max rate.
