* usb: host: ohci-platform: remove custom USB PHY handlingMartin Blumenstingl2018-03-091-51/+5
| | | | | | | | | | | | | The new PHY wrapper is now wired up in the core HCD code. This means that PHYs are now controlled (initialized, enabled, disabled, exited) without requiring any host-driver specific code. Remove the custom USB PHY handling from the ohci-platform driver as the core HCD code now handles this.

* usb: add a flag to skip PHY initialization to struct usb_hcdMartin Blumenstingl2018-03-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The USB HCD core driver parses the device-tree node for "phys" and "usb-phys" properties. It also manages the power state of these PHYs automatically. However, drivers may opt-out of this behavior by setting "phy" or "usb_phy" in struct usb_hcd to a non-null value. An example where this is required is the "Qualcomm USB2 controller", implemented by the chipidea driver. The hardware requires that the PHY is only powered on after the "reset completed" event from the controller is received. A follow-up patch will allow the USB HCD core driver to manage more than one PHY. Add a new "skip_phy_initialization" bitflag to struct usb_hcd so drivers can opt-out of any PHY management provided by the USB HCD core driver. This also updates the existing drivers so they use the new flag if they want to opt out of the PHY management provided by the USB HCD core driver. This means that for these drivers the new "multiple PHY" handling (which will be added in a follow-up patch) will be disabled as well.

* USB: host: ohci: Remove redundant license textGreg Kroah-Hartman2017-11-071-2/+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.

* USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-041-0/+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. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

| | | | | | | | | | | | | | | | | | | | The ohci-platform driver checks for misconfigurations in cases where the Device Tree data specifies big-endian registers or descriptors but the corresponding driver config settings have not been enabled. As Jonas Gorski suggested, we may as well apply the same check to general platform data too. This requires moving the code that sets the big-endian quirk flags from the ohci_platform_reset() routine into ohci_platform_probe(), and moving the checks out of the DT-specific "if" statement clause. The patch also changes the text of the error messages in an attempt to make the nature of the error more clear.

* ohci-platform: Change compatible string from usb-ohci to generic-ohciHans de Goede2014-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The initial versions of the devicetree enablement patches for ohci-platform used "ohci-platform" as compatible string. However this was disliked by various reviewers because the platform bus is a Linux invention and devicetree is supposed to be OS agnostic. After much discussion I gave up and went with the generic usb-ohci as requested. In retro-spect I should have chosen something different, the dts files for many existing boards already claim to be compatible with "usb-ohci", ie they have: compatible = "ti,ohci-omap3", "usb-ohci"; In theory this should not be a problem since the "ti,ohci-omap3" entry takes presedence, but in practice using a conflicting compatible string is an issue, because it makes which driver gets used depend on driver registration order. This patch changes the compatible string claimed by ohci-platform to "generic-ohci", avoiding the driver registration / module loading ordering problems.

* drivers/usb/host/ohci-platform.c: fix error return codeJulia Lawall2012-08-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert a possibly 0 error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier ret; expression e,e1,e2,e3,e4,x; @@ ( if (\(ret != 0\|ret < 0\) || ...) { ... return ...; } | ret = 0 ) ... when != ret = e1 *x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...); ... when != x = e2 when != ret = e3 *if (x == NULL || ...) { ... when != ret = e4 * return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | usb_ohci_pdata is certainly required in ohci-platform driver. This patch avoids using BUG_ON() from driver, and return from probe with WARN_ON() if pdata was NULL.

* USB: OHCI: Add a generic platform device driverHauke Mehrtens2012-03-151-0/+194
This adds a generic driver for platform devices. It works like the PCI driver and is based on it. This is for devices which do not have an own bus but their OHCI controller works like a PCI controller. It will be used for the Broadcom bcma and ssb USB OHCI controller.
