apbmisc reg for Tegra30 can be divided into following entries:
strap registers jtag configuration registers pull_up/pull_down control registers vclk control registers tvdac registers chip id revision registers pad control registers
This list is not same for Tegra20 and Tegra30.
OR
another way is to add chip id revision register region to CAR node as done for pinmux node and remove apb misc node.
What is preferred?
