[PATCH v4 0/7] UFS on APQ8098/MSM8998

From: Marc Gonzalez
Date: Fri Feb 08 2019 - 17:23:22 EST


Hello,

This series adds support for the UFS host controller on
APQ8098/MSM8998-based boards.

I CCed the regulator maintainers to discuss the revert in
patch 6. Basically, the original patch added a quirk which
forcefully disables vccq when the UFSHC is connected to a
Samsung or Hynix Flash chip. Problem is, this disabling
breaks init on my board, and Jeffrey's board as well.
Hence the revert, for which I don't see any adverse
consequences?

Differences between v3 and v4:
- Rebase on top of -next
- Pick up Douglas Anderson's UFSHC doc fix
- Document 8998 UFSHC binding
- Improve UFS PHY binding doc
- Put the UFS DT patch at the end of the series

Difference between v2 and v3:
- Add qcom,msm8998-qmp-ufs-phy compat string and match it in the PHY driver
- Drop vdd-hba-fixed-regulator
- Write the reg addresses with full 32-bit width
- Set regulator-allow-set-load only on the 3 rails used by UFS.
- Revert the patch introducing ufshcd_set_vccq_rail_unused

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
