such as CAR.
nvidia,tegra30-apbmisc means. Also, the register range for this new node
overlaps that for the pinmux node, so they can't both "request" their
register region. You may need multiple entries in the apbmisc reg
property to avoid this.
apbmisc reg for Tegra30 can be divided into following entries:
jtag configuration registers
pull_up/pull_down control registers
vclk control registers
chip id revision registers
pad control registers
This list is not same for Tegra20 and Tegra30.
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?
