Subject: [PATCH v4 00/16] Tegra XHCI controller ELPG support
Date: Fri, 16 Oct 2020 21:07:10 +0800 [thread overview]
Message-ID: <20201016130726.1378666-1-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 (16):
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
arm64: tegra210/tegra186/tegra194: XUSB PADCTL irq
usb: host: xhci-tegra: Unlink power domain devices
xhci: tegra: Enable ELPG for runtime/system PM
