Controller address and its mapping

hi all,
I am new to this platform. I understand the blsp address are got from corresponding blsp guide.
I am trying to understand from where the controller address are got and mapped correctly.
eg: sdhci@74a4900

From where this controller address is got for db820c.

Could any one guide me on this.

Thanks in advance

From the msm8996 manual/datasheet I assume, but this documentation is not publicly available. You need to discuss with your vendor, or Qualcomm if you need access.

Thanks for your response @Loic
