Subject: [PATCH v6 00/15] Tegra XHCI controller ELPG support
Date: Tue, 19 Jan 2021 16:55:31 +0800	[thread overview]
Message-ID: <20210119085546.725005-1-jckuo@nvidia.com> (raw)

Tegra XHCI controler can be placed in ELPG (Engine Level PowerGated)
state for power saving when all of the connected USB devices are in
suspended state. This patch series includes clk, phy and pmc changes
that are required for properly place controller in ELPG and bring
controller out of ELPG.

JC Kuo (15):
  clk: tegra: Add PLLE HW power sequencer control
  clk: tegra: Don't enable PLLE HW sequencer at init
  phy: tegra: xusb: Move usb3 port init for Tegra210
  phy: tegra: xusb: tegra210: Do not reset UPHY PLL
  phy: tegra: xusb: Rearrange UPHY init on Tegra210
  phy: tegra: xusb: Add Tegra210 lane_iddq operation
  phy: tegra: xusb: Add sleepwalk and suspend/resume
  soc/tegra: pmc: Provide USB sleepwalk register map
  arm64: tegra210: XUSB PADCTL add "nvidia,pmc" prop
  dt-bindings: phy: tegra-xusb: Add nvidia,pmc prop
  phy: tegra: xusb: Add wake/sleepwalk for Tegra210
  phy: tegra: xusb: Tegra210 host mode VBUS control
  phy: tegra: xusb: Add wake/sleepwalk for Tegra186
  usb: host: xhci-tegra: Unlink power domain devices
  xhci: tegra: Enable ELPG for runtime/system PM
