However, this code has no effect after commit 41863fc (ACPI / power: Drop automaitc resume of power resource dependent devices) and the mechanism it was supposed to implement is regarded as a bad idea now, so drop it.

It is racy, because if the power resource is turned on and then immediately off, the device resume triggered by the first transition to "on" may still happen, causing the power resource to be turned on again. That again will trigger the "resume of dependent devices" mechanism, but if the devices in question are not in use, they will be suspended in the meantime causing the power resource to be turned off. However, the "resume of dependent devices" will next resume them again and so on. In some cases (USB port PM in particular) that leads to an endless busy loop of flipping the resource on and off continuously. It is needless, because whoever turns a power resource on will most likely turn it off at some point and the devices that go into "D0" as a result of turning it on will then go back into D3cold (generally, the state they were in before). Moreover, turning on all power resources a device needs to go into D0 is not sufficient for a full transition into D0 in general. Namely, _PS0 may need to be executed in addition to that in some cases. This means that the whole rationale of the "resume of dependent devices" mechanism was incorrect to begin with and it's best to remove it entirely. Signed-off-by: Rafael J.

| | | * | | | | | xhci: Fix spurious wakeups after S5 on HaswellTakashi Iwai2013-10-093-0/+25

After discussing with BIOS engineers, they explained that the new BIOS expects that the wakeup sources are cleared and set to D3 for all wakeup devices when the system is going to sleep or power off, but the current xhci driver doesn't do this properly (partly intentionally). This patch introduces a new quirk, XHCI_SPURIOUS_WAKEUP, for fixing the spurious wakeups at S5 by calling xhci_reset() in the xhci shutdown ops as done in xhci_stop(), and setting the device to PCI D3 at shutdown and remove ops. The PCI D3 call is based on the initial fix patch by Oliver Neukum. [Note: Sarah changed the quirk name from XHCI_HSW_SPURIOUS_WAKEUP to XHCI_SPURIOUS_WAKEUP, since none of the other quirks have system names in them. Sarah also fixed a collision with a quirk submitted around the same time, by changing the xhci->quirks bit from 17 to 18.] This patch should be backported to kernels as old as 3.0, that contain the commit 1c12443ab8eba71a658fae4572147e56d1f84f66 "xhci: Add Lynx Point to list of Intel switchable hosts."

It has nothing to do with the device suspend remote wakeup from L2. The RWE bit is designed to be set once (when USB 2.0 LPM is enabled for the port) and cleared only when USB 2.0 LPM is disabled for the port. The xHCI bus suspend method was setting the RWE bit erroneously, and the bus resume method was clearing it. The xHCI 1.0 specification with errata up to Aug 12, 2012 says in section 4.23.5.1.1.1 "Hardware Controlled LPM": "While Hardware USB2 LPM is enabled, software shall not modify the HIRDBESL or RWE fields of the USB2 PORTPMSC register..." If we have previously enabled USB 2.0 LPM for a device, that means when the USB 2.0 bus is resumed, we violate the xHCI specification by clearing RWE. It also means that after a bus resume, the host would think remote wakeup is disabled from L1 for ports with USB 2.0 Link PM enabled, which is not what we want. This patch should be backported to kernels as old as 3.2, that contain the commit 65580b4321eb36f16ae8b5987bfa1bb948fc5112 "xHCI: set USB2 hardware LPM". That was the first kernel that supported USB 2.0 Link PM. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: stable@vger.kernel.org

Since commit fe4cb09 ("usb: musb: gadget: remove hcd initialization") the loaded gadget does non pop up on the host. All I see is |usb 4-5: new high-speed USB device number 52 using ehci-pci |usb 4-5: device descriptor read/64, error -110 Since a later commit 2cc65fe ("usb: musb: add musb_host_setup() and musb_host_cleanup()) the gadget shows up on the host again but only in OTG mode (because we have the host init code running). It does not work in device only mode. If running in OTG mode and the gadget is removed and added back (rmmod followed by modprobe of a gadget) then the same error is pops up on the host side. This patch ensures that the gadget side also executes musb_start() which puts the chip in "connect accept" mode. With this change the device works in OTG & device mode and the gadget can be added & removed multiple times. A device (if musb is in OTG mode acting as a host) is only recognized if it is attached during module load (musb_hdrc module). After the device unplugged and plugged again the host does not recognize it. We get a buch of errors if musb running in OTG mode, attached to a host and no gadget is loaded. Bah. This is one step forward. Host & device only mode should work. I will look at OTG later. I looked at this before commit fe4cb09 and OTG wasn't working there perfectly so I am not sure that it is a regression :) Cc: <stable@vger.kernel.org> # v3.11 Cc: Daniel Mack <zonque@gmail.com> Cc: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>

Conversely, if device_node was NULL, an unitialized port ended up being used. This patch adds the missing braces, fixing the issues.
