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. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

This reverts commit e872154921a6b5256a3c412dd69158ac0b135176. Andrey Borzenkov reports that it resulted in a totally hung machine for him when loading the OHCI driver. Extensive netconsole capture with SysRq output shows that modprobe gets stuck in ohci_hub_status_data() when probing and enabling the OHCI controller, see for example http://lkml.org/lkml/2008/7/5/236 for an analysis. The problem appears to be an interrupt flood triggered by the commit that gets reverted, and Andrey confirmed that the revert makes things work for him again.

The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.

2006-09-27USB: Properly unregister reboot notifier in case of failure in ehci hcdAleksey Gorelov1-0/+2
If some problem occurs during ehci startup, for instance, request_irq fails, echi hcd driver tries it best to cleanup, but fails to unregister reboot notifier, which in turn leads to crash on reboot/poweroff. The following patch resolves this problem by not using reboot notifiers anymore, but instead making ehci/ohci driver get its own shutdown method. For PCI, it is done through pci glue, for everything else through platform driver glue. One downside: sa1111 does not use platform driver stuff, and does not have its own shutdown hook, so no 'shutdown' is called for it now. I'm not sure if it is really necessary on that platform, though.

2006-09-27USB: ohci-s3c2410.c: clock now usb-bus-hostBen Dooks1-1/+1
With the newer Samsung S3C2412 and S3C2413 SoC devices, the 48MHz USB clock has been given an individual gate into the USB OHCI and gadget blocks. This clock is called usb-bus-clock, and we need to replace the old use of the USB PLL (upll) directly with the new usb-bus-host. The S3C2410 clock driver has been updated already to provide a virtual clock which is a child of the UPLL to maintain compatibility. The S3C2412 clock driver correctly enables the PLL when either usb-bus clock is active. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-27USB: OHCI avoids root hub timer pollingDavid Brownell1-0/+1
This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing root hub timers most of the time and switching over to the "new" root hub polling scheme. It's complicated by the fact that implementations of OHCI trigger and ack that IRQ differently (the spec is vague there). Avoiding root hub timers helps mechanisms like "dynamic tick" leave the CPU in lowpower modes for longer intervals.

2006-04-14[PATCH] USB: S3C2410: use clk_enable() to ensure 48MHz to OHCI coreBen Dooks1-8/+24
Get the "usb-bus" clock and ensure it is enabled when the OHCI core is in use. It seems that a few bootloaders do not enable the UPLL at startup, which stops the OHCI core having a 48MHz bus clock. The improvements to the clock framework for the s3c24xx now allow the USB PLL to be started and stopped when being used.

It seems that clk_use() and clk_unuse() are additional complexity which isn't required anymore. Remove them from the clock framework to avoid the additional confusion which they cause, and update all ARM machine types except for OMAP. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
