pinctrl: samsung: Remove bogus irq_[un]mask from resource management

2017-08-16T20:40:30+00:00

commit 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c upstream. The irq chip callbacks irq_request/release_resources() have absolutely no business with masking and unmasking the irq. The core code unmasks the interrupt after complete setup and masks it before invoking irq_release_resources(). The unmask is actually harmful as it happens before the interrupt is completely initialized in __setup_irq(). Remove it.

pinctrl: sunxi: add a missing function of A10/A20 pinctrl driver

2017-08-16T20:40:30+00:00

commit d81ece747d8727bb8b1cfc9a20dbe62f09a4e35a upstream. The PH16 pin has a function with mux id 0x5, which is the DET pin of the "sim" (smart card reader) IP block. This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver. Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now.

pnfs/blocklayout: require 64-bit sector_t

2017-08-16T20:40:30+00:00

commit 8a9d6e964d318533ba3d2901ce153ba317c99a89 upstream. The blocklayout code does not compile cleanly for a 32-bit sector_t, and also has no reliable checks for devices sizes, which makes it unsafe to use with a kernel that doesn't support large block devices.

iio: adc: vf610_adc: Fix VALT selection value for REFSEL bits

2017-08-16T20:40:30+00:00

commit d466d3c1217406b14b834335b5b4b33c0d45bd09 upstream. In order to select the alternate voltage reference pair (VALTH/VALTL), the right value for the REFSEL field in the ADCx_CFG register is "01", leading to 0x800 as register mask. See section 8.2.6.4 in the reference manual[1].

usb:xhci:Add quirk for Certain failing HP keyboard on reset after resume

2017-08-16T20:40:30+00:00

commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 upstream. Certain HP keyboards would keep inputting a character automatically which is the wake-up key after S3 resume On some AMD platforms USB host fails to respond (by holding resume-K) to USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures that resume is signaled for at least 20 ms (TDRSMDN), which is defined in USB 2.0 spec. The result is that the keyboard is out of function. In SNPS USB design, the host responds to the resume request only after system gets back to S0 and the host gets to functional after the internal HW restore operation that is more than 1 second after the initial resume request from the USB device. As a workaround for specific keyboard ID(HP Keyboards), applying port reset after resume when the keyboard is plugged in.

usb: quirks: Add no-lpm quirk for Moshi USB to Ethernet Adapter

2017-08-16T20:40:30+00:00

commit 7496cfe5431f21da5d27a8388c326397e3f0a5db upstream. Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to connect to Realtek r8153. The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk can make it work. Since another r8153 dongle at my hand does not have the issue, so add the quirk to the Genesys Logic hub instead. Signed-off-by: Kai-Heng Feng Signed-off-by: Greg Kroah-Hartman

usb: core: unlink urbs from the tail of the endpoint's urb_list

2017-08-16T20:40:30+00:00

commit 2eac13624364db5b5e1666ae0bb3a4d36bc56b6e upstream. While unlink an urb, if the urb has been programmed in the controller, the controller driver might do some hw related actions to tear down the urb. Currently usb_hcd_flush_endpoint() passes each urb from the head of the endpoint's urb_list to the controller driver, which could make the controller driver think each urb has been programmed and take the unnecessary actions for each urb. This patch changes the behavior in usb_hcd_flush_endpoint() to pass the urbs from the tail of the list, to avoid any unnecessary actions in an controller driver.

USB: Check for dropped connection before switching to full speed

2017-08-16T20:40:30+00:00

commit 94c43b9897abf4ea366ed4dba027494e080c7050 upstream. Some buggy USB disk adapters disconnect and reconnect multiple times during the enumeration procedure. This may lead to a device connecting at full speed instead of high speed, because when the USB stack sees that a device isn't able to enumerate at high speed, it tries to hand the connection over to a full-speed companion controller. The logic for doing this is careful to check that the device is still connected. But this check is inadequate if the device disconnects and reconnects before the check is done. The symptom is that a device works, but much more slowly than it is capable of operating. The situation was made worse recently by commit 22547c4cc4fe ("usb: hub: Wait for connection to be reestablished after port reset"), which increases the delay following a reset before a disconnect is recognized, thus giving the device more time to reconnect. This patch makes the check more robust. If the device was disconnected at any time during enumeration, we will now skip the full-speed handover.
