I wanted to use devm_ioremap_resource but could not find DT entry
required for this driver in any of the .dts files. So did not change
that. I could not find any dts/dtsi for this platform. So I assume
that the dtb is not present in the kernel, dtb is supplied by the
bootloader. I may be wrong in this. Can anyone confirm this?
