[RFC,v2,0/4] UFS on APQ8098

Message

Hello,

After weeks (literally!) of poking the system at random, Jeffrey found why UFS
refused to work on APQ8098: we were not setting the load on the vregs.

Difference between v1 and v2:
- New patch to add 'regulator-allow-set-load' prop to all vreg nodes
- Rename rpmcc node to 'clock-controller' + Add Review tags
- Drop UFS pinctrl gymnastics (not required, probably left enabled in bootloader)
- Delete GCC_UFS_ICE_CORE_CLK (ICE not used upstream, I think)
- Fix sizes of ufsphy register areas based on Jeffrey's feedback
- Hack ufshcd_set_vccq_rail_unused into a NOP to work around lock up + reboot


Marc Gonzalez (4):
  arm64: dts: qcom: msm8998: Add rpmcc node
  arm64: dts: qcom: msm8998: Add UFS nodes
  Add regulator-allow-set-load
  ufshcd_set_vccq_rail_unused locks up the board
