4 - compatible : For Tegra30, must contain "nvidia,tegra30-ahub". For Tegra114,
5 must contain "nvidia,tegra114-ahub". For Tegra124, must contain
6 "nvidia,tegra124-ahub". Otherwise, must contain "nvidia,<chip>-ahub",
9 the AHUB's register blocks.
10 - Tegra30 requires 2 entries, for the APBIF and AHUB/AUDIO register blocks.
12 - interrupts : Should contain AHUB interrupt
58 AHUB client modules need to specify the IDs of their CIFs (Client InterFaces).
59 For RX CIFs, the numbers indicate the register number within AHUB routing
61 For TX CIFs, the numbers indicate the bit position within the AHUB routing
