Subject: [PATCH 00/12] Tegra XHCI controller ELPG support
Date: Fri, 28 Aug 2020 09:10:44 +0800 [thread overview]
Message-ID: <20200828011056.1067559-1-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 (12):
clk: tegra: Add PLLE HW power sequencer control
clk: tegra: don't enable PLLE HW sequencer at init
phy: tegra: xusb: t210: rearrange UPHY init
phy: tegra: xusb: t210: add lane_iddq operations
phy: tegra: xusb: add sleepwalk and suspend/resume
soc/tegra: pmc: provide usb sleepwalk register map
arm64: tegra210: XUSB PADCTL add "nvidia,pmc" prop
phy: tegra: xusb: t210: support wake and sleepwalk
phy: tegra: xusb: t186: support wake and sleepwalk
arm64: tegra210/tegra186/tegra194: XUSB PADCTL irq
usb: host: xhci-tegra: unlink power domain devices
xhci: tegra: enable ELPG for runtime/system PM
