* usb: gadget: f_midi: fix leak on failed to enqueue out requestsFelipe F. Tonello2015-11-191-0/+1
| | | | | | | | | This patch fixes a memory leak that occurs when an endpoint fails to enqueue the request. If that happens the complete function will never be called, thus never freeing the request. Signed-off-by: Felipe F. Tonello <eu@felipetonello.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: dwc2: Return errors from PHYStefan Wahren2015-11-191-5/+32
| | | | | | | | | | | | | | | | When searching for PHYs, any error was treated as if the PHY did not exist or was not specified. Thus the probe function did not correctly return error conditions such as -EPROBE_DEFER. Fixed so that only a non-existing PHY is ignored and any other error is returned.

* usb: renesas_usbhs: gadget: Fix NULL pointer dereference in usbhsg_ep_dequeue()Yoshihiro Shimoda2015-11-191-2/+9
| | | | | | | | | | | This patch fixes an issue that NULL pointer dereference happens when a gadget driver calls usb_ep_dequeue() for ep0 after disconnected a usb cable. This is because that usbhsg_try_stop() will call usbhsg_ep_disable(&dcp->ep) when a usb cable is disconnected and the pipe of dcp (ep0) is set to NULL.

| | | | | | | | | | | | | | | | | pxa27x disconnects pullups on suspend but doesn't notify the gadget driver about it, so gadget driver can't disable the endpoints it was using. This causes problems on resume because gadget core will think endpoints are still enabled and just ignore the following usb_ep_enable(). Fix this problem by calling gadget_driver->disconnect().

* usb: gadget: atmel_usba_udc: Expose correct device speedDouglas Gilbert2015-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | Following changes that appeared in lk 4.0.0, the gadget udc driver for some ARM based Atmel SoCs (e.g. at91sam9x5 and sama5d3 families) incorrectly deduced full-speed USB link speed even when the hardware had negotiated a high-speed link. The fix is to make sure that the UDPHS Interrupt Enable Register value does not mask the SPEED bit in the Interrupt Status Register. For a mass storage gadget this problem lead to failures when the host had a USB 3 port with the xhci_hcd driver. If the host was a USB 2 port using the ehci_hcd driver then the mass storage gadget worked (but probably at a lower speed than it should have).

* usb: dwc3: gadget: let us set lower max_speedBen McCauley2015-11-171-1/+23
| | | | | | | | | | | | | | | | | | | | | | | In some SoCs, dwc3 is implemented as a USB2.0 only core, meaning that it can't ever achieve SuperSpeed. Currect driver always sets gadget.max_speed to USB_SPEED_SUPER unconditionally. This can causes issues to some Host stacks where the host will issue a GetBOS() request and we will reply with a BOS containing Superspeed Capability Descriptor. At least Windows seems to be upset by this fact and prints a warning that we should connect $this device to another port.

* usb: musb: fix tx fifo flush handlingBin Liu2015-11-171-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are a few changes in musb_h_tx_flush_fifo(). - It has been observed that sometimes (if not always) musb is unable to flush tx fifo during urb dequeue when disconnect a device. But it seems to be harmless, since the tx fifo flush is done again in musb_ep_program() when re-use the hw_ep. But the WARN() floods the console in the case when multiple tx urbs are queued, so change it to dev_WARN_ONCE(). - applications could queue up many tx urbs, then the 1ms delay could causes minutes of delay in device disconnect. So remove it to get better user experience. The 1ms delay does not help the flushing anyway. - cleanup the debug code - related to lastcsr. ---- Note: The tx fifo flush issue has been observed during device disconnect on AM335x. To reproduce the issue, ensure tx urb(s) are queued when unplug the usb device which is connected to AM335x usb host port. I found using a usb-ethernet device and running iperf (client on AM335x) has very high chance to trigger the problem. Better to turn on dev_dbg() in musb_cleanup_urb() with CPPI enabled to see the issue when aborting the tx channel. Signed-off-by: Bin Liu <b-liu@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: dwc2: host: Fix remote wakeup when not in DWC2_L2Douglas Anderson2015-11-171-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 734643dfbdde ("usb: dwc2: host: add flag to reflect bus state") we changed dwc2_port_suspend() not to set the lx_state anymore (instead it sets the new bus_suspended variable). This introduced a bug where we would fail to detect device insertions if: 1. Plug empty hub into dwc2 2. Plug USB flash drive into the empty hub. 3. Wait a few seconds 4. Unplug USB flash drive 5. Less than 2 seconds after step 4, plug the USB flash drive in again. The dwc2_hcd_rem_wakeup() function should have been changed to look at the new bus_suspended variable. Let's fix it. Since commit b46146d59fda ("usb: dwc2: host: resume root hub on remote wakeup") talks about needing the root hub resumed if the bus was suspended, we'll include it in our test. It appears that the "port_l1_change" should only be set to 1 if we were in DWC2_L1 (the driver currently never sets this), so we'll update the former "else" case based on this test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The comment for ahbcfg for rk3066 parameters (also used for rk3288) claimed that ahbcfg was INCR16, but it wasn't. Since the bits weren't shifted properly, the 0x7 ended up being masked and we ended up programming 0x3 for the HBstLen. Let's set it to INCR16 properly. As per Wu Liang Feng at Rockchip this may increase transmission efficiency. I did blackbox tests with writing 0s to a USB-based SD reader (forcefully capping CPU Freq to try to measure efficiency): cd /sys/devices/system/cpu/cpu0/cpufreq echo userspace > scaling_governor echo 126000 > scaling_setspeed for i in $(seq 10); do dd if=/dev/zero of=/dev/sdb bs=1M count=750 done With the above tests I found that speeds went from ~15MB/s to ~18MB/s. Note that most other tests I did (including reading from the same USB reader) didn't show any difference in performance.

| * MIPS: VDSO: Add implementations of gettimeofday() and clock_gettime()Alex Smith2015-11-111-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add user-mode implementations of gettimeofday() and clock_gettime() to the VDSO. This is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below the VDSO data page. When a supported clocksource is not in use, the VDSO functions will return -ENOSYS, which causes libc to fall back on the standard syscall path. When support for neither of these clocksources is compiled into the kernel at all, the VDSO still provides clock_gettime(), as the coarse realtime/monotonic clocks can still be implemented. However, gettimeofday() is not provided in this case as nothing can be done without a suitable clocksource. This causes the symbol lookup to fail in libc and it will then always use the standard syscall path. This patch includes a workaround for a bug in QEMU which results in RDHWR on the CP0 count register always returning a constant (incorrect) value. A fix for this has been submitted, and the workaround can be removed after the fix has been in stable releases for a reasonable amount of time. A simple performance test which calls gettimeofday() 1000 times in a loop and calculates the average execution time gives the following results on a Malta + I6400 (running at 20MHz): - Syscall: ~31000 ns - VDSO (GIC): ~15000 ns - VDSO (CP0): ~9500 ns [markos.chandras@imgtec.com: - Minor code re-arrangements in order for mappings to be made in the order they appear to the process' address space. - Move do_{monotonic, realtime} outside of the MIPS_CLOCK_VSYSCALL ifdef - Use gic_get_usm_range so we can do the GIC mapping in the arch/mips/kernel/vdso instead of the GIC irqchip driver] Signed-off-by: Alex Smith <alex.smith@imgtec.com> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-kernel@vger.kernel.org Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/11338/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Mixing select and depends on is bad practice as it may lead to circular Kconfig dependencies. Since the platform devices that are matched with these drivers are registered by the ChromeOS EC mfd driver, they really depend on MFD_CROS_EC. And because this config option selects CROS_EC_PROTO, that dependency is met as well. So make the drivers to depend on MFD_CROS_EC instead of CROS_EC_PROTO.

It's possible that it can't actually return -EIO and this patch is not needed but in that case this patch is harmless and silences a static checker warning so it's still worth it.

In order to catch all variants of the Yoga 3, I'm changing both the entry for the 1470 (using "Yoga" as the name) and the entry for the Pro 1370 (using all-caps "YOGA") to not match the exact model number but only the generation. This way, the 1170 and 1470 models share one entry, but if the firmware changes from one format to the other, it will still work. The second entry for Yoga 2 Pro that was recently added for some reason ended up not being added in alphanumeric order, and I'm moving the Yoga 3 1470 entry down while making the change, so they are sorted more logically.

Unfortunately, the Yoga 3 11/13/14 models have one important exception, which is the Fn-ESC combination. On other Lenovo Laptops, this is FnLock, which switches the function keys between the primary (Mute, Vol down, Vol up, ...) and the secondary (F1, F2, F3, ...) behavior. On the new machines, FnLock is only available through BIOS setup (possibly through a yet-to-be-implemented feature in this driver) but not through Fn-ESC, but instead the ESC key itself switched between ESC and a "Paper Display" app for Windows. Unfortunately, that means that you can never have both ESC *and* the function keys working at the same time without needing to press Fn on one of them. As pointed out in the official Lenovo Forum by dozens of users, this makes the machine rather useless for any serious work [1]. I have now studied the ACPI DSDT one more time and found the event that is generated for the ESC key. Unlike all other key events on this machine, it is actually a WMI, while the other ones are read from the embedded controller. I am now installing a WMI notifier that uses the event number from the WMI subsystem as the scancode. The only event number generated here is '128', and that fits in nicely with the two existing ranges of scancodes used by the EC: 0-15 for the 16-bit VPCCMD_R_VPC register, 16-17 for the VPCCMD_R_NOVO register and 64-67 for VPCCMD_R_SPECIAL_BUTTONS. The only sane way to handle this button (in absence of the Windows Paper Display driver) seems to be to have it emit KEY_ESC, so that is what I use as the default. Should any user ever want to overwrite the default, they can install their own keymap. To ensure that we can still build the driver without adding a CONFIG_WMI dependency, all new code is enclosed in #ifdef.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates the SPI functionality from core functionality that overlaps with the tsc2004. Prepares kernel for new tsc2004 driver without much redundant code. Signed-off-by: Michael Welling <mwelling@ieee.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Unfortunately, this caused a compile failure (detected by linux-next), which then had to be fixed up and incubated. In addition to the mpt2/3sas rework, there are updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus an assortment of changes including some year 2038 issues, a fix for a remove before detach issue in some drivers and a couple of other minor issues" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits) mpt3sas: fix inline markers on non inline function declarations sd: Clear PS bit before Mode Select. ibmvscsi: set max_lun to 32 ibmvscsi: display default value for max_id, max_lun and max_channel. mptfusion: don't allow negative bytes in kbuf_alloc_2_sgl() scsi: pmcraid: replace struct timeval with ktime_get_real_seconds() mvumi: 64bit value for seconds_since1970 be2iscsi: Fix bogus WARN_ON length check scsi_scan: don't dump trace when scsi_prep_async_scan() is called twice mpt3sas: Bump mpt3sas driver version to 09.102.00.00 mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAs mpt2sas, mpt3sas: Update the driver versions mpt3sas: setpci reset kernel oops fix mpt3sas: Added OEM Gen2 PnP ID branding names mpt3sas: Refcount fw_events and fix unsafe list usage mpt3sas: Refcount sas_device objects and fix unsafe list usage mpt3sas: sysfs attribute to report Backup Rail Monitor Status mpt3sas: Ported WarpDrive product SSS6200 support mpt3sas: fix for driver fails EEH, recovery from injected pci bus error mpt3sas: Manage MSI-X vectors according to HBA device type ...
