* USB: Add driver for NXP ISP1301 USB transceiverRoland Stigge2012-05-011-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | This new driver registers the NXP ISP1301 chip via the I2C subsystem. The chip is the USB transceiver shared by ohci-nxp, lpc32xx_udc (gadget) and isp1301_omap. ISP1301 is a very low-level driver that primarily separates out the I2C client registration of the ISP1301 chip (including instantiation via DT), used by other drivers, and declares the chip's registers. It's only a helper driver for some OHCI and USB device drivers. The driver can be considered as a register set extension of ohci-nxp, lpc32xx-udc and isp1301_omap, which in turn know best what to do with the low level functionality (individual ISP1301 registers and timing, see the different initialization strategies in those drivers). Those drivers previously internally duplicated ISP1301 register definitions which is solved by this new isp1301 driver. The ISP1301 registers exposed via isp1301.h can be accessed by other drivers using it with standard i2c_smbus_*() accesses. Following patches let the respective USB host and gadget drivers use this driver, instead of duplicating ISP1301 handling.

* usbhid: prevent deadlock during timeoutOliver Neukum2012-05-011-0/+3
| | | | | | | | | | | | | | | On some HCDs usb_unlink_urb() can directly call the completion handler. That limits the spinlocks that can be taken in the handler to locks not held while calling usb_unlink_urb() To prevent a race with resubmission, this patch exposes usbcore's infrastructure for blocking submission, uses it and so drops the lock without causing a race in usbhid.

| | | | | | | | | I thought this had been removed years ago. All in-kernel users of this call have now been cleaned up and converted over to use dev_err() instead, which is the correct thing to do.

The incoming cpuidle driver uses the 'prcmu_enable_wakeups' and the 'prcmu_set_power_state' functions but these ones are defined but not implemented for the db5500, leading to an unresolved symbol error at link time. In order to compile, we have to disable the db5500 support which is not acceptable for the default config. I noticed there are also some other functions which are defined but not implemented. This patch fix this by removing the functions definitions and move out of the config section the empty functions which are normally used when the DB550 config is disabled. Only the functions which are not implemented are concerned by this modification.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have to export our internal do_mmap_pgoff() function. Some day we hopefully don't have to export do_mmap() either, if all modular users can become the simpler vm_mmap() instead. We're actually very close to that already, with the notable exception of the (broken) use in i810, and a couple of stragglers in binfmt_elf.

For the dwc3 driver we have a memory leak fix, a very important fix for USB30CV with SetFeature tests and the hability to handle ep0 requests bigger than wMaxPacketSize. On top of that there's a bunch of gadget driver minor fixes adding proper section annotations, and fixing up the sysfs interface for doing device-initiated connect/disconnect and so on. All patches have been pending on the mailing list for quite a while and look good for your for-linus branch.

This can lead to a page leak as pages are pinned using get_user_pages, but only unpinned with put_page if they still exist in the memslots list on vm shutdown. A memslot that is destroyed while an iommu domain is enabled for the guest will therefore result in an elevated page reference count that is never cleared. Additionally, without this fix, the iommu is only programmed with the first translation for a gpa. This can result in peer-to-peer errors if a mapping is destroyed and replaced by a new mapping at the same gpa as the iommu will still be pointing to the original, pinned memory address.

Platforms that wish to use the regulator API to manage their power domains can indirect via the power domain interface. This feature is only used with the vape supply of the db8500 PRCMU driver which supplies the UARTs and MMC controllers, none of which have support for managing vcore at runtime in mainline (only pl022 SPI controller does). Update that supply to have an always_on constraint until the power domain support for the system is updated so that it is enabled for these users, this is likely to have no impact on practical systems as probably at least one of these devices will be active and cause AMBA to hold the supply on anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC's NULL is actually __null, which allows detecting some questionable NULL usage and warn about it. Moreover each platform/compiler should have its own stddef.h anyway (which is different from linux/stddef.h). So there's no good reason to leak kernel's NULL to userspace and override what the compiler provides.

This results in a huge autoconf.h file, on the order of 16k lines for a x86_64 defconfig. Fixing IS_ENABLED to be able to work on the smaller subset of just things that we really have defined is step one to fixing this. Which means it has to not choke when fed non-enabled options, such as: include/linux/netdevice.h:964:1: warning: "__enabled_CONFIG_FCOE_MODULE" is not defined [-Wundef] The original prototype of how to implement a C and preprocessor compatible way of doing this came from the Google+ user "comex ." in response to Linus' crowdsourcing challenge for a possible improvement on his earlier C specific solution: #define config_enabled(x) (__stringify(x)[0] == '1') In this implementation, I've chosen variable names that hopefully make how it works more understandable.

Unloading and reloading a serial driver while a serial device is plugged in causes errors because of the code in usb_serial_disconnect() that tries to make sure the port_remove method is called. With the new order of driver registration introduced in the 3.4 kernel, this is definitely not the right thing to do (if indeed it ever was). The patch removes that whole section code, along with the mechanism for keeping track of each port's registration state, which is no longer needed. The driver core can handle all that stuff for us. Note: This has been tested only with one or two USB serial drivers. In theory, other drivers might still run into trouble. But if they do, it will be the fault of the drivers, not of this patch -- that is, the drivers will need to be fixed.

Register reads coincident with new interrupt notifications sometimes result in this device clearing the interrupt event without reporting it in the read data. The serial core already has a heuristic for determining when a device has an untrustworthy iir register. In this case when we apriori know that the iir is faulty use a flag (UPF_BUG_THRE) to bypass the test and force usage of the background timer.

The semantic of UPF_IIR_ONCE is only guaranteed to workaround the race condition in the kt serial's iir register if the only source of interrupts is THRE (fifo-empty) events. An modem status event at the wrong time can again cause an iir read to drop the 'empty' status leading to a hang. So, revert this in preparation for using the existing "I don't trust my iir register" workaround in the 8250 core (UART_BUG_THRE).
