2017-10-21iio: dac: Add Texas Instruments 8/10/12-bit 2/4-channel DAC driverGravatar Lukas Wunner 1-0/+1
The DACrrcS085 (rr = 08/10/12, c = 2/4) family of SPI DACs was inherited by TI when they acquired National Semiconductor in 2011. This driver was developed for and tested with the DAC082S085 built into the Revolution Pi by KUNBUS, but should work with any of the other chips as they share the same programming interface. There is also a family of I2C DACs with just a single channel called DACrr1C08x (rr = 08/10/12, x = 1/5). Their programming interface is very similar and it should be possible to extend the driver for these chips with moderate effort. Alternatively they could be integrated into ad5446.c. (The AD5301/AD5311/AD5321 use different power-down modes but otherwise appear to be comparable.) Furthermore there is a family of 8-channel DACs called DACrr8S085 (rr = 08/10/12) as well as two 16-bit DACs called DAC161Sxxx (xxx = 055/997). These are more complicated devices with support for daisy-chaining and the ability to power down each channel separately. They could either be handled by a separate driver or integrated into the present driver with a larger effort.

2017-10-13mm, swap: use page-cluster as max window of VMA based swap readaheadGravatar Huang Ying 1-10/+0
When the VMA based swap readahead was introduced, a new knob /sys/kernel/mm/swap/vma_ra_max_order was added as the max window of VMA swap readahead. This is to make it possible to use different max window for VMA based readahead and original physical readahead. But Minchan Kim pointed out that this will cause a regression because setting page-cluster sysctl to zero cannot disable swap readahead with the change. To fix the regression, the page-cluster sysctl is used as the max window of both the VMA based swap readahead and original physical swap readahead. If more fine grained control is needed in the future, more knobs can be added as the subordinate knobs of the page-cluster sysctl. The vma_ra_max_order knob is deleted. Because the knob was introduced in v4.14-rc1, and this patch is targeting being merged before v4.14 releasing, there should be no existing users of this newly added ABI.

2017-10-05dm raid: fix incorrect status output at the end of a "recover" processGravatar Jonathan Brassow 1-0/+1
There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().

2017-10-05ovl: fix regression caused by exclusive upper/work dir protectionGravatar Amir Goldstein 1-1/+4
Enforcing exclusive ownership on upper/work dirs caused a docker regression: https://github.com/moby/moby/issues/34672. Euan spotted the regression and pointed to the offending commit. Vivek has brought the regression to my attention and provided this reproducer: Terminal 1: mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none merged/ Terminal 2: unshare -m Terminal 1: umount merged mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none merged/ mount: /root/overlay-testing/merged: none already mounted or mount point busy To fix the regression, I replaced the error with an alarming warning. With index feature enabled, mount does fail, but logs a suggestion to override exclusive dir protection by disabling index. Note that index=off mount does take the inuse locks, so a concurrent index=off will issue the warning and a concurrent index=on mount will fail. Documentation was updated to reflect this change.

This could arguably be moved to the next merge window but it also seemed relatively harmless to include now. - Amlogic/meson had driver changes merged that required devicetree changes to avoid functional/performance regressions. I've already asked them to be more careful about this going forward, and making sure drivers are compatible with older DTs when they make these kind of changes.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Round one of new device support, features and cleanup for IIO in the 4.15 cycle. Note there is a misc driver drop in here given we have support in IIO and the feeling is no one will care. A large part of this series is a boiler plate removal series avoiding the need to explicitly provide THIS_MODULE in various locations. It's very dull but touches all drivers. New device support * ad5446 - add ids to support compatible parts DAC081S101, DAC101S101, DAC121S101. - add the dac7512 id and drop the misc driver as feeling is no one is using it (was introduced for a board that is long obsolete) * mt6577 - add bindings for mt2712 which is fully compatible with other supported parts. * st_pressure - add support for LPS33HW and LPS35HW with bindings (ids mostly). New features * ccs811 - Add support for the data ready trigger. * mma8452 - remove artifical restriction on supporting multiple event types at the same time. * tcs3472 - support out of threshold events Core and tree wide cleanup * Use macro magic to remove the need to provide THIS_MODULE as part of struct iio_info or struct iio_trigger_ops. This is similar to work done in a number of other subsystems (e.g. i2c, spi). All drivers are fixed and then the fields in these structures are removed. This will cause build failures for out of tree drivers and any new drivers that cross with this work going into the kernel. Note mostly done with a coccinelle patch, included in the series on the mailing list but not merged as the fields no longer exist in the structures so the any hold outs will cause a build failure. Cleanups * ads1015 - avoid writing config register when it doesn't change. - add 10% to conversion wait time as it seems it is sometimes a little small. * ade7753 - replace use of core mlock with a local lock. This is part of a long term effort to make the use of mlock opaque and single purpose. * ade7759 - expand the use of buf_lock to cover previous mlock cases. This is a slightly nicer solution to the same issue as in ade7753. * cros_ec - drop an unused variable * inv_mpu6050 - add a missing break in a switch for consistency - not actual bug, - make some local arrays static to save on object code size. * max5481 - drop manual setting of the spi module owner as handled by the spi core. * max5487 - drop manual setting of the spi module owner as handled by the spi core. * max9611 - drop explicit setting of the i2c module owner as handled by the i2c core. * mcp320x - speed up reads on single channel devices, - drop unused of_device_id data elements, - document the struct mcp320x, - improve binding docs to reflect restrictions on spi setup and to make it explicit that the reference regulator is needed. * mma8452 - symbolic to octal permissions, - unsigned to unsigned int. * st_lsm6dsx - avoid setting odr values multiple times, - drop config of LIR as it is only ever set to the existing defaults, - drop rounding configuration as it only ever matches the defaults. * ti-ads8688 - drop manual setting of the spi module owner as handled by the spi core. * tsl2x7x - constify the i2c_device_id, - cleanup limit checks to avoid static checker warnings (and generally have nicer code).

All chips supported by this driver clock data out on the falling edge and latch data in on the rising edge, hence SPI mode (0,0) or (1,1) must be used. Furthermore, none of the chips has an internal reference voltage regulator, so an external supply is always required and needs to be specified in the device tree lest the IIO "scale" in sysfs cannot be calculated. Document these requirements in the device tree binding, add compatible strings for the newly supported mcp3550/1/3 and explain that SPI mode (0,0) should be preferred for these chips.

Use integers (reg property) to tell the number of the LED to the driver instead of the node name. While both of these approaches are currently used by the LED bindings, using integers will require less driver changes for ACPI support. Additionally, it will make possible LED naming using chip and LED node names, effectively making the label property most useful for human-readable names only.
