2015-08-26gpio: vf610: handle level IRQ's properlyStefan Agner
The GPIO IRQ controller is able to generate level triggered interrupts, however, these were handled by handle_simple_irq so far which did not take care of IRQ masking. This lead to "nobody cared (try booting with the "irqpoll" option)" stack traces. Use the generic interrupt handlers depending on the IRQ type.

2015-08-26pinctrl: mediatek: Fix multiple registration issue.Hongzhou Yang
Since our common driver need support main chip and PMU at the same time, that means it will register two pinctrl device, and the pinctrl_desc structure should be used two times. But pinctrl_desc use global static definition, then the latest registered pinctrl device will overwrite the old one's, all members in pinctrl_desc will set to the new one's, such as name, pins and pins numbers, etc. This is a bug. Move pinctrl_desc into mtk_pinctrl, assign new value for each pinctrl device to fix it.

2015-08-26powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF caseGuilherme G. Piccoli
Since commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the disable of MSI/MSI-X interrupts isn't being done at PCI probe time, as the logic responsible for this was moved in the aforementioned commit from pci_device_add() to pci_setup_device(). The latter function is not reachable on PowerPC pseries platform during Open Firmware PCI probing time. This exhibits as drivers not being able to enable MSI, eg: bnx2x 0000:01:00.0: no msix capability found This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X during PCI probe time on pSeries platform.

2015-08-26PCI: Make pci_msi_setup_pci_dev() non-static for use by arch codeGuilherme G. Piccoli
Commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI") changed the location of the code that initialises dev->msi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI probe time in devices that have this flag set. It moved the code from pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(), called by pci_setup_device(). The pseries PCI probing code does not call pci_setup_device(), so since the aforementioned commit the function pci_msi_setup_pci_dev() is not called and MSI/MSI-X interrupts are left enabled. Additionally because dev->msi_cap/msix_cap are not initialised no driver can ever enable MSI/MSI-X. To fix this, the pseries PCI probe should manually call pci_msi_setup_pci_dev(), so this patch makes it non-static.

This adds additional 0x0041 PCI Device ID definition to ath10k for QCA6164 which is a 1 spatial stream sibling of the QCA6174 (which is 2 spatial stream chip). The QCA6164 needs a dedicated board.bin file which is different than the one used for QCA6174. If the board.bin is wrong the device will crash early while trying to boot firmware. The register dump will look like this: ath10k_pci 0000:02:00.0: firmware register dump: ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 0x00955B31 ... Note the value 0x000A012D.

2015-08-26ath10k: add spectral scan support for 10.4 fwRaja Mani
To enable/configure spectral scan parameters in 10.4 firmware, existing wmi spectral related functions can be reused. Link those functions in 10.4 wmi ops table. In addition, adjust bin size (only when size is 68 bytes) before reporting bin samples to user space. The background for this adjustment is that qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte carries band edge detection data (+32) mainly used in radar detection purpose. Additional last 4 bytes are stripped to make bin size valid one. This bin size adjustment will happen only for qca99x0, all other chipsets will report proper bin sizes (64/128) without extra 4 bytes being added at the end. The changes are validated in qca99x0 using 10.4 firmware. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-08-26gpio: omap: fix clk_prepare/unprepare usageGrygorii Strashko
As per CCF documentation (clk.txt) the clk_prepare/unprepare APIs are not allowed in atomic context. But now OMAP GPIO driver uses them while applying debounce settings and as part of PM runtime irqsafe operations: - omap_gpio_debounce() is holding the lock with IRQs off. + omap2_set_gpio_debounce() + clk_prepare_enable() + clk_prepare() this one might sleep. - pm_runtime_get_sync() is holding the lock with IRQs off + omap_gpio_runtime_suspend() + raw_spin_lock_irqsave() + omap_gpio_dbck_disable() + clk_disable_unprepare() Hence, fix it by moeving dbclk prepare/unprepare in OMAP GPIO omap_gpio_probe/omap_gpio_remove. Also, while here, ensure that debounce functionality is disabled if clk_get() failed, because otherwise kernel will carsh in omap2_set_gpio_debounce().

2015-08-26gpio: omap: fix omap2_set_gpio_debounceGrygorii Strashko
According to TRMs: Required input line stable = (the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME + 1) × 31, where the value of the GPIO_DEBOUNCINGTIME[7:0].DEBOUNCETIME bit field is from 0 to 255. But now omap2_set_gpio_debounce() will calculate debounce time and behave incorrectly in the following cases: 1) requested debounce time is !0 and <32 calculated DEBOUNCETIME = 0x1 == 62 us; expected value of DEBOUNCETIME = 0x0 == 31us 2) requested debounce time is 0 calculated DEBOUNCETIME = 0x1 == 62 us; expected: disable debounce and DEBOUNCETIME = 0x0 3) requested debounce time is >32 and <63 calculated DEBOUNCETIME = 0x0 and debounce will be disabled; expected: enable debounce and DEBOUNCETIME = 0x1 == 62 us Hence, rework omap2_set_gpio_debounce() to fix above cases: 1) introduce local variable "enable" and use it to identify when debounce need to be enabled or disabled. Disable debounce if requested debounce time is 0. 2) use below formula for debounce time calculation: debounce = (DIV_ROUND_UP(debounce, 31) - 1) & 0xFF; Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Santosh Shilimkar <ssantosh@kernel.org> Tested-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2015-08-26surface pro 3: Add support driver for Surface Pro 3 buttonsChen Yu
Since Surface Pro 3 does not follow the specs of "Windows ACPI Design Guide for SoC Platform", code in drivers/input/misc/soc_array.c can not detect these buttons on it. According to bios implementation, Surface Pro 3 encapsulates these buttons in a device named "VGBI", with _HID "MSHW0028". When any of the buttons is pressed, a specify ACPI notification code for this button will be delivered to "VGBI". For example, if power button is pressed down, ACPI notification code of 0xc6 will be sent by Notify(VGBI, 0xc6). This patch leverages "VGBI" to distinguish different ACPI notification code from Power button, Home button, Volume button, then dispatches these code to input layer. Lid is already covered by acpi button driver, so there's no need to rewrite.

2015-08-26ALSA: hda - Fix widget sysfs tree corruption after refreshTakashi Iwai
When snd_hdac_refresh_widget_sysfs() is called before the first hda_widget_sysfs_init(), the next call overrides and eventually fails. This results in unexpected Oops, something like: BUG: unable to handle kernel NULL pointer dereference at 00000000000000c8 IP: [<ffffffff8180e2a3>] hdmi_chmap_ctl_info+0x23/0x40 The fix is to add a check of the existing sysfs tree. Also, for more safety, this patch adds the checks of device_is_registered() in snd-hdac_refresh_wdiget_sysfs(), too.

2015-08-26dmaengine: hdmac: Add memset capabilitiesMaxime Ripard
Just like for the XDMAC, the SoCs that embed the HDMAC don't have any kind of GPU, and need to accelerate a few framebuffer-related operations through their DMA controller. However, unlike the XDMAC, the HDMAC doesn't have the memset capability built-in. That can be easily emulated though, by doing a transfer with a fixed address on the variable that holds the value we want to set.
