JC Kuo c545a90567 phy: tegra: xusb: Add sleepwalk and suspend/resume ... This commit adds sleepwalk/wake and suspend/resume interfaces to Tegra XUSB PHY driver. Tegra XUSB host controller driver makes use of sleepwalk functions to enable/disable sleepwalk circuit which is in always-on partition and can respond to USB resume signals when controller is not powered. Sleepwalk can be enabled/disabled for any USB UPHY individually. - tegra_xusb_padctl_enable_phy_sleepwalk() - tegra_xusb_padctl_disable_phy_sleepwalk() Tegra XUSB host controller driver makes use of wake functions to enable/disable/query wake circuit which is in always-on partition can wake system up when USB resume happens. Wake circuit can be enabled/disabled for any USB PHY individually. - tegra_xusb_padctl_enable_phy_wake() - tegra_xusb_padctl_disable_phy_wake() - tegra_xusb_padctl_remote_wake_detected() This commit also adds two system suspend stubs that can be used to save and restore XUSB PADCTL context during system suspend and resume. - tegra_xusb_padctl_suspend_noirq() - tegra_xusb_padctl_resume_noirq() Signed-off-by: JC Kuo <jckuo@nvidia.com> Acked-By: Vinod Koul <vkoul@kernel.org> Signed-off-by: Thierry Reding <treding@nvidia.com>		2021-06-03 14:49:34 +02:00
