Analyze and fix the following issue in the Linux kernel code: arm64: dts: qcom: sc7280: Fix the base addresses of LLCC banks
Problem Details: The LLCC block has several banks each with a different base address and holes in between. So it is not a correct approach to cover these banks with a single offset/size. Instead, the individual bank's base address needs to be specified in devicetree with the exact size. While at it, let's also fix the...
