Subject: [PATCH v3 0/3] soc: qcom: llcc: Add LLCC support for the QCS8300
 platform

The QCS8300 platform has LLCC(Last Level Cache Controller) as the system
cache controller. Add binding, configuration and device tree node to
support this. There is an errata to get the number of the banks of the
LLCC on QCS8300 platform, hardcode it as a workaround.

This series depends on below patch series:

Changes in v3:
- patch rebased for using "num_banks" property defined in the config for hardcoding
- Add reviewed-by tag for dt change
- Link to v2: https://lore.kernel.org/r/20241010-qcs8300_llcc-v2-0-d4123a241db2@quicinc.com

Changes in v2:
- Hardcoding instead of adding property in dt node and remove related patches
- Add LLCC deivcetree node
- Add reviewed-by tag for binding change
- Patch rebased for LLCC configuration format change
- Link to v1: https://lore.kernel.org/r/20240903-qcs8300_llcc_driver-v1-0-228659bdf067@quicinc.com
