2018-12-07Revert "usb: dwc3: pci: Use devm functions to get the phy GPIOs"Stephan Gerhold1-4/+4
Commit 211f658b7b40 ("usb: dwc3: pci: Use devm functions to get the phy GPIOs") changed the code to claim the PHY GPIOs permanently for Intel Baytrail devices. This causes issues when the actual PHY driver attempts to claim the same GPIO descriptors. For example, tusb1210 now fails to probe with: tusb1210: probe of dwc3.0.auto.ulpi failed with error -16 (EBUSY) dwc3-pci needs to turn on the PHY once before dwc3 is loaded, but usually the PHY driver will then hold the GPIOs to turn off the PHY when requested (e.g. during suspend). To fix the problem, this reverts the commit to restore the old behavior to put the GPIOs immediately after usage.

2018-11-14usb: dwc3: Fix NULL pointer exception in dwc3_pci_remove()Kuppuswamy Sathyanarayanan1-1/+3
In dwc3_pci_quirks() function, gpiod lookup table is only registered for baytrail SOC. But in dwc3_pci_remove(), we try to unregistered it without any checks. This leads to NULL pointer de-reference exception in gpiod_remove_lookup_table() when unloading the module for non baytrail SOCs. This patch fixes this issue.

2018-07-26usb: dwc3: pci: Add GPIO lookup table on platforms without ACPI GPIO resourcesHans de Goede1-0/+18
Bay Trail / BYT SoCs do not have a builtin device-mode phy, instead they require an external ULPI phy for device-mode. Only some BYT devices have an external phy, but even on those devices device-mode is not working because the dwc3 does not see the phy. The problem is that the ACPI fwnode for the dwc3 does not contain the expected GPIO resources for the GPIOs connected to the chip-select and reset pins of the phy. I've found the workaround which some Android x86 kernels use for this: https://github.com/BORETS24/Kernel-for-Asus-Zenfone-2/blob/master/arch/x86/platform/intel-mid/device_libs/pci/platform_usb_otg.c Which boils down to hardcoding the GPIOs for these devices. The good news it that all boards (*) use the same GPIOs. This commit fixes the ULPI phy not woring by adding a gpiod_lookup_table call which adds a hardcoded mapping for BYT devices. Note that the mapping added by gpiod_add_lookup_table is a fallback mapping, so boards which properly provide GPIO resources in the ACPI firmware-node resources will not use this. *) Except for the first revision of the evalulation-kit, which normal users don't have Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2017-11-07USB: dwc3: Remove redundant license textGreg Kroah-Hartman1-9/+0
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman1-0/+1
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

2017-10-24usb: dwc3: pci: Runtime resume child device from wqManu Gautam1-2/+27
Driver currently resumes and increments pm usage_count of its child device (dwc3 main) from its runtime_resume handler. This requires dwc3 runtime_resume to perform pm_runtime_put to decrement the pm usage_count. However runtime_put from dwc3 happens for non pci drivers (e.g. dwc3-if-simple.c) as well which results in dwc3 pm usage_count becoming negative after couple of runtime suspend resume iterations. Fix this by performing runtime_get/put from dwc3-pci driver only using workqueue. Signed-off-by: Manu Gautam <mgautam@codeaurora.org> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2017-06-28PM / core: Drop run_wake flag from struct dev_pm_infoRafael J. Wysocki1-2/+1
The run_wake flag in struct dev_pm_info is used to indicate whether or not the device is capable of generating remote wakeup signals at run time (or in the system working state), but the distinction between runtime remote wakeup and system wakeup signaling has always been rather artificial. The only practical reason for it to exist at the core level was that ACPI and PCI treated those two cases differently, but that's not the case any more after recent changes. For this reason, get rid of the run_wake flag and, when applicable, use device_set_wakeup_capable() and device_can_wakeup() instead of device_set_run_wake() and device_run_wake(), respectively.
