git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Second set of IIO fixes for the 4.9 cycle. Interestingly scale related fixes for accelerometers at both ends of the range. Obviously more varied devices turning up than we've seen before! * ad5933 - fix an uninitialized value in a return case that is winding up GCC. * hid sensors - missing pm function prevents hid rotations sensors from working on newer ISH hubs (works by luck on older ones) - increase of scale precision needed to fix a case where on a yoga 260 the reported scale is 0 (presumably a high precision but very low g sensor). * st_sensors - fix an issue seen with the hs3lis331dl where the range is much greater than previous devices (100's of g) and hence the per bit scale is greater than 1.

2016-11-06mm/filemap: don't allow partially uptodate page for pipesEryu Guan1-0/+3
Starting from 4.9-rc1 kernel, I started noticing some test failures of sendfile(2) and splice(2) (sendfile0N and splice01 from LTP) when testing on sub-page block size filesystems (tested both XFS and ext4), these syscalls start to return EIO in the tests. e.g. sendfile02 1 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 26, got: -1 sendfile02 2 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 24, got: -1 sendfile02 3 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 22, got: -1 sendfile02 4 TFAIL : sendfile02.c:133: sendfile(2) failed to return expected value, expected: 20, got: -1 This is because that in sub-page block size cases, we don't need the whole page to be uptodate, only the part we care about is uptodate is OK (if fs has ->is_partially_uptodate defined). But page_cache_pipe_buf_confirm() doesn't have the ability to check the partially-uptodate case, it needs the whole page to be uptodate. So it returns EIO in this case. This is a regression introduced by commit 82c156f85384 ("switch generic_file_splice_read() to use of ->read_iter()"). Prior to the change, generic_file_splice_read() doesn't allow partially-uptodate page either, so it worked fine. Fix it by skipping the partially-uptodate check if we're working on a pipe in do_generic_file_read(), so we read the whole page from disk as long as the page is not uptodate.

Commit efd9e03facd0 ("arm64: Use static keys for CPU features") introduced support for static keys in asm/cpufeature.h, including linux/jump_label.h.

interpretation. While testing, it was observed that on some platforms the scale value from iio sysfs for gyroscope is always 0 (E.g. Yoga 260). This results in the final angular velocity component values to be zeros. This is caused by insufficient precision of scale value displayed in sysfs. If the precision is changed to nano from current micro, then this is sufficient to display the scale value on this platform. Since this can be a problem for all other HID sensors, increase scale precision of all HID sensors to nano from current micro.

Add common hid sensor iio pm function for rotation sensor. Further clarification from Srinivas: If CONFIG_PM is not defined, then this prevents this sensor to function. So above commit caused this.

2016-11-05HID: sensor: fix attributes in HID sensor interfaceOoi, Joyce1-3/+3
User is unable to access to input-X-yyy and feature-X-yyy where X is a hex value and more than 9 (e.g. input-a-yyy, feature-b-yyy) in HID sensor custom sysfs interface. This is because when creating the attribute, the attribute index is written to using %x (hex). However, when reading and writing values into the attribute, the attribute index is scanned using %d (decimal). Hence, user is unable to access to attributes with index in hex values (e.g. 'a', 'b', 'c') but able to access to attributes with index in decimal values (e.g. 1, 2, 3,..). This fix will change input-%d-%x-%s and feature-%d-%x-%s to input-%x-%x-%s and feature-%x-%x-%s in show_values() and store_values() accordingly.

But IRQF_NO_SUSPEND and IRQF_SHARED should not be used together, so removed IRQF_NO_SUSPEND flag.

2016-11-05phy: sun4i: check PMU presence when poking unknown bit of pmuIcenowy Zheng1-1/+1
Allwinner SoC's PHY 0, when used as OTG controller, have no pmu part. The code that poke some unknown bit of PMU for H3/A64 didn't check the PHY, and will cause kernel oops when PHY 0 is used. This patch will check whether the pmu is not NULL before poking.

2016-11-05phy-rockchip-pcie: remove deassert of phy_rst from exit callbackShawn Lin1-12/+1
The deassert of phy_rst from exit callback is incorrect as when doing phy_exit, we expect the phy_rst is on asserted state which was done by power_off callback, but not deasserted state. Meanwhile when disabling clk_pciephy_ref, the assert/deassert signal can't actually take effect on the phy. So let's fix it anyway.

2016-11-05pinctrl: cherryview: Prevent possible interrupt storm on resumeMika Westerberg1-3/+4
When the system is suspended to S3 the BIOS might re-initialize certain GPIO pins back to their original state or it may re-program interrupt mask of others. For example Acer TravelMate B116-M had BIOS bug where certain GPIO pin (MF_ISH_GPIO_5) was programmed to trigger on high level, and the pin state was high once the BIOS gave control to the OS on resume. This triggers lots of messages like: irq 117, desc: ffff88017a61e600, depth: 1, count: 0, unhandled: 0 ->handle_irq(): ffffffff8109b613, handle_bad_irq+0x0/0x1e0 ->irq_data.chip(): ffffffffa0020180, chv_pinctrl_exit+0x2d84/0x12 [pinctrl_cherryview] ->action(): (null) IRQ_NOPROBE set We reset the mask back to known state in chv_pinctrl_resume() but that is called only after device interrupts have already been enabled. Now, this particular issue was fixed by upgrading the BIOS to the latest (v1.23) but not everybody upgrades their BIOSes so we fix it up in the driver as well. Prevent the possible interrupt storm by moving suspend and resume hooks to be called at _noirq time instead. Since device interrupts are still disabled we can restore the mask back to known state before interrupt storm happens.

If async suspend is enabled, the driver may access registers concurrently with another instance which may fail because of the bug in Cherryview GPIO hardware. Prevent this by taking the shared lock while accessing the hardware in suspend and resume hooks.

2016-11-04PCI: designware: Check for iATU unroll support after initializing hostNiklas Cassel1-2/+5
dw_pcie_iatu_unroll_enabled() reads a dbi_base register. Reading any dbi_base register before pp->ops->host_init has been called causes "imprecise external abort" on platforms like ARTPEC-6, where the PCIe module is disabled at boot and first enabled in pp->ops->host_init. Move dw_pcie_iatu_unroll_enabled() to dw_pcie_setup_rc(), since it is after pp->ops->host_init, but before pp->iatu_unroll_enabled is actually used.
