Subject: [PATCH v2 0/6] Add support for MSM8996 GDSCs

Changes since v1:
* For votable gdscs which are 'on' at boot, put an explicit vote
* Added a delay post disable for votable gdscs
* Added back the status check after timeout
* rearranged some patch ordering to avoid bisect issues

This series adds support for GDSCs' which are part of gcc and mmcc
in QCOM msm8996 SoC. Series applies on top of clk-next

There are many more cases of gdscs within gdscs (hierarchical power
domains) in msm8996 (msm8974 has one such instance which is supported
upstream) and hence the series adds support within gdsc driver to
handle this.

Also msm8996 has gdscs with gds hw controllers within, for ensuring
slave device idleness before gdscs are powered off, hence the series
also adds support for gdscs with gds hw controllers.

ToDo: Series does not yet add support for gpu gdscs which are part
of mmcc

Tested on apq8096 dragonboards to make sure all modelled gdscs can
be turned on/off successfully

Rajendra Nayak (6):
  clk: qcom: gdsc: Add support for hierarchical power domains
  clk: qcom: gdsc: Add support for gdscs with gds hw controller
