Subject: [PATCH 0/2] soc: hisilicon: Add power control support for kunpeng HBM

Add power control support for High Bandwidth Memory (HBM) for Kunpeng SoC
platform. HBM devices on Kunpeng SoC can provide higher bandwidth at the
cost of higher power consumption. Providing power control methods can help
reducing the power when the workload does not need use HBM.

Zhang Zekun (2):
  soc: hisilicon: kunpeng_hbmdev: Add support for controling the power
    of hbm memory
  soc: hisilicon: kunpeng_hbmcache: Add support for online and offline
    the hbm cache
