2015-10-09usb: dwc3: pci: Set enblslpm quirk for Synopsys platformsJohn Youn1-0/+1
Certain Synopsys prototyping PHY boards are not able to meet timings constraints for LPM. This allows the PHY to meet those timings by leaving the PHY clock running during suspend.

2015-07-29usb: dwc3: pci: make better use of gpiod APIUwe Kleine-König1-10/+16
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Use this additional parameter and the _optional variant to simplify the driver and improve error handling. Also expand the comment to explain why it's not sensible to switch to devm_gpiod_get and why the gpiod_put is also necessary. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.

The "nop" driver isn't a do-nothing-stub but supports a couple functions like clock on/off or is able to use a voltage regulator. This patch simply renames the driver to "generic" since it is easy possible to extend it by a simple function istead of writing a complete driver.

2013-07-29usb: dwc3: switch to GPL v2 onlyFelipe Balbi1-28/+8
This is a Linux-only driver which makes use of GPL-only symbols. It makes no sense to maintain Dual BSD/GPL licensing for this driver. Considering that the amount of work to use this driver in any different operating system would likely be as large as developing the driver from scratch and considering that we depend on GPL-only symbols, we will switch over to a GPL v2-only license.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.11 merge window All function drivers are now converted to our new configfs-based binding. Eventually this will help us getting rid of in-kernel gadget drivers and only keep function drivers in the kernel. MUSB was taught that it needs to be built for host-only and device-only modes too. We had this support long ago but it involved a ridiculous amount of ifdefs. Now we have a much cleaner approach. Samsung Exynos4 platform now implements HSIC support. We're introducing support for AB8540 and AB9540 PHYs. MUSB module reinsertion now works as expected, before we were getting -EBUSY being returned by the resource checks done on driver core. DWC3 now has minimum support for TI's AM437x series of SoCs. OMAP5 USB3 PHY learned one extra DPLL configuration values because that PHY is reused in TI's DRA7xx devices. We're introducing support for Faraday fotg210 UDCs. Last, but not least, the usual set of non-critical fixes and cleanups ranging from usage of platform_{get,set}_drvdata to lock improvements.

2013-05-28usb: dwc3: pci: PHY should be deleted later than dwc3 corePeter Chen1-1/+1
If the glue layer is removed first (core layer later), it deletes the phy device first, then the core device. But at core's removal, it still uses PHY's resources, it may cause kernel's oops. It is much like the problem Paul Zimmerman reported at: http://marc.info/?l=linux-usb&m=136547502011472&w=2. Besides, it is reasonable the PHY is deleted at last as the controller is the PHY's user.

2012-01-04drivers/usb/dwc3/dwc3-pci.c: introduce missing kfreeJulia Lawall1-1/+1
Glue needs to be freed on exiting the function in an error case. Furthermore, pci, which is the first argument to the probe function should not be freed before leaveing the function, as it is reused at the call site. So the free of pci is changed to free glue instead. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
