Spi enumeration in trm

Tegra186_Linux_R32.5.1_aarch64.tbz2 device tree bootloader/t186ref/BCT/tegra194-p2888-0001-p2822-0000.dtb contains aliases and symbols:

spi0 = "/spi@3210000";
spi1 = "/spi@c260000";
spi2 = "/spi@3230000";

Xavier Series SoC Technical Reference Manual 1.4p has on p. 42ff.

SPI1  0x03210000  0x0321ffff  SYSTEM
SPI3  0x03230000  0x0323ffff  SYSTEM
SPI2  0x0c260000  0x0c26ffff  SYSTEM

Why is it different? How do I find out, what start address the PADCTL_AO_SPI2_CS0_0 is connected to? Is it 0x03230000 or 0x0c260000?

Thanks for your support!

TRM is HW name count from 1, device is count from 0
The PADCTL_AO_SPI2_CS0_0 is HW SPI2 so it is software SPI1 aka spi@c260000
