2017-06-02frv: declare jiffies to be located in the .data sectionMatthias Kaehlcke
Commit 7c30f352c852 ("jiffies.h: declare jiffies and jiffies_64 with ____cacheline_aligned_in_smp") removed a section specification from the jiffies declaration that caused conflicts on some platforms. Unfortunately this change broke the build for frv: kernel/built-in.o: In function `__do_softirq': (.text+0x6460): relocation truncated to fit: R_FRV_GPREL12 against symbol `jiffies' defined in *ABS* section in .tmp_vmlinux1 kernel/built-in.o: In function `__do_softirq': (.text+0x6574): relocation truncated to fit: R_FRV_GPREL12 against symbol `jiffies' defined in *ABS* section in .tmp_vmlinux1 kernel/built-in.o: In function `pwq_activate_delayed_work': workqueue.c:(.text+0x15b9c): relocation truncated to fit: R_FRV_GPREL12 against symbol `jiffies' defined in *ABS* section in .tmp_vmlinux1 ... Add __jiffy_arch_data to the declaration of jiffies and use it on frv to include the section specification. For all other platforms __jiffy_arch_data (currently) has no effect.

At the time commit 7e7844226f10 ("lockdep: allow to disable reclaim lockup detection") was written we still had __GFP_OTHER_NODE but I have removed it in commit 41b6167e8f74 ("mm: get rid of __GFP_OTHER_NODE") and forgot to lower the bit value.

2017-06-02i2c: sh_mobile: remove platform_dataWolfram Sang
No platform currently upstream makes use of this platform_data anymore. The ones that did are converted to DT meanwhile. So, remove it. The old platforms likely don't have the 'clks_per_cnt' feature, otherwise it would have been implemented by now. And in the unlikely case they need to setup a different bus speed, we should rather go for a generic i2c platform data just for that.

2017-06-01mtd: nand: add support for Micron on-die ECCThomas Petazzoni
Now that the core NAND subsystem has support for on-die ECC, this commit brings the necessary code to support on-die ECC on Micron NANDs. In micron_nand_init(), we detect if the Micron NAND chip supports on-die ECC mode, by checking a number of conditions: - It must be an ONFI NAND - It must be a SLC NAND - Enabling *and* disabling on-die ECC must work - The on-die ECC must be correcting 4 bits per 512 bytes of data. Some Micron NAND chips have an on-die ECC able to correct 8 bits per 512 bytes of data, but they work slightly differently and therefore we don't support them in this patch. Then, if the on-die ECC cannot be disabled (some Micron NAND have on-die ECC forcefully enabled), we bail out, as we don't support such NANDs. Indeed, the implementation of raw_read()/raw_write() make the assumption that on-die ECC can be disabled. Support for Micron NANDs with on-die ECC forcefully enabled can easily be added, but in the absence of such HW for testing, we preferred to simply bail out. If the on-die ECC is supported, and requested in the Device Tree, then it is indeed enabled, by using custom implementations of the ->read_page(), ->read_page_raw(), ->write_page() and ->write_page_raw() operation to properly handle the on-die ECC. In the non-raw functions, we need to enable the internal ECC engine before issuing the NAND_CMD_READ0 or NAND_CMD_SEQIN commands, which is why we set the NAND_ECC_CUSTOM_PAGE_ACCESS option at initialization time (it asks the NAND core to let the NAND driver issue those commands).

2017-05-30mtd: nand: Make sure drivers not supporting SET/GET_FEATURES return -ENOTSUPPBoris Brezillon
A lot of drivers are providing their own ->cmdfunc(), and most of the time this implementation does not support all possible NAND operations. But since ->cmdfunc() cannot return an error code, the core has no way to know that the operation it requested is not supported. This is a problem we cannot address for all kind of operations with the current design, but we can prevent these silent failures for the GET/SET FEATURES operation by overloading the default ->onfi_{set,get}_features() methods with one returning -ENOTSUPP.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control fixes from Linus Walleij: "Here is an overdue pull request for pin control fixes, the most prominent feature is to make Intel Chromebooks (and I suspect any other Cherryview-based Intel thing) happy again, which we really want to see. There is a patch hitting drivers/firmware/* that I was uncertain to who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's review tags on it and I trust them both 100% to do the right thing for Intel platform drivers. Summary: - Make a few Intel Chromebooks with Cherryview DMI firmware work smoothly. - A fix for some bogus allocations in the generic group management code. - Some GPIO descriptor lookup table stubs. Merged through the pin control tree for administrative reasons. - Revert the "bi-directional" and "output-enable" generic properties: we need more discussions around this. It seems other SoCs are using input/output gate enablement and these terms are not correct. - Fix mux and drive strength atomically in the MXS driver. - Fix the SPDIF function on sunxi A83T. - OF table terminators and other small fixes" * tag 'pinctrl-v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: pinctrl: sunxi: Fix SPDIF function name for A83T pinctrl: mxs: atomically switch mux and drive strength config pinctrl: cherryview: Extend the Chromebook DMI quirk to Intel_Strago systems firmware: dmi: Add DMI_PRODUCT_FAMILY identification string pinctrl: core: Fix warning by removing bogus code gpiolib: Add stubs for gpiod lookup table interface Revert "pinctrl: generic: Add bi-directional and output-enable" pinctrl: cherryview: Add terminate entry for dmi_system_id tables

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.13 cycle Two entirely new drivers in here plus the usual range of cleanups and features. New device support * ad5064 - add ltc2631, ltc2633 and ltc2635 support. * bma180 - trivial support for bma250e (new id) * hid-sensor-rotation - add relative orientation and geometric orientation support. * isl29028 - add isl29030 support (its effectively the same part from a driver point of view) * maxim_thermocouple - add max31856 id. * meson-saradc - add meson8b SoC adc support. * ti-adc084s021 - new driver and bindings. * ti-adc108s102 - new driver and bindings. Staging graduations * isl29028 Features * bma180 - ACPI enumeration for BMA250E which is used in various x86 tablets. * hi8453 - add raw access rather than only events. * hid-sensor-hub - Implement batch mode in which we can set a threshold on the amount of time between data coming from the fifos. This is the first device to do this rather than use a watershed on the number of samples. * hts221 - power management support * lsm6dsx - add system power management support. * rpr0521 - sampling frequency read / write * stm32-trigger - add support for TRG02 triggers. * tsl2583 - runtime power management support. Cleanups * core - inkern: fix a double unlock in iio_read_available_channel_raw when raw value doesn't appear to be raw (error path). - fixup accidental sizeof pointer in iio_device_add_mask_type. * docs - fix an accidental duplicated line in sysfs-bus-iio-meas-spec. * tools - use local include/uapi headers to ensure always up to date. - increase length of allowed trigger names. * ad9834 - symbolic to octal permissions. * ade7753 - symbolic to octal permissions. - fix indentation * ade7754 - symbolic to octal permissions. * ade7758 - symbolic to octal permissions. - ade7854 - symbolic to octal permissions. * as3935 - move out of storm check to given consistent results for raw and processed values. * bmp280 - fix bme280 naming in Kconfig help. * hi8435 - avoid garbage on event after enable. - add missing in_voltage_sensing_mode_available to list possible enum options. - handle the reset gpio with the obvious polarity rather than relying on DT to provide it correctly. * hid-sensors - fix a wrong error path scrubbing of return values. * hid-sensors-accel - drop static on a local variable * hid-sensors-rotation - Add missing scale and offset property parsing support. * ina2xx - Fix a bad use of GENMASK and some typos and whitespace issues. * isl29018 - only declare the ACPI table when ACPI is enabled. * isl29028 - fix proximity sleep times. * lsm6dsx - replace ifdef CONFIG_PM with __maybe_unused to avoid the complexity of dealing with the various PM config variables. * meson-saradc - mark meson_sar_adc_data static and const. * rcar-gyroadc - derive the interface clock speed from the fck clock on the basis they are the same actual clock. - drop the now unused if clock from the bindings. * rpr0521 - disable sensor when marked as such rather than always enabling it. - poweroff if probe fails and we can talk to device. - make sure device powered off when it doesn't need to be on. - use sizeof rather than hardcoded size on value read. - whitespace fixup. - reorder channel numbers ready for buffered support which didn't quite make this pull request. * st-accel - fix platform data initialization to allow remove and reprobe. * st-pressure - fix platform data initialization to allow remove and reprobe. * tsl2x7x - S_IRUGO, S_IWUSR to octal values - rename driver for consistency with more recent drivers - drop FSF mailing address - replace DEVICE_ATTR macros with the shorter DEVICE_ATTR_RW form and relevant function renames. * zpa2326 - report an error for consistency with other error paths.
