This isn't just an internal detail, since xrandr actually exposes "VGA" as the output name. Define some new enums so that vc4's DPI can have a more informative name. I considered other names for the connector as well. For VC4, the Adafruit DPI kippah takes the 28 GPIO pins and routes them to a standard-ish 40-pin FPC connector, but "40-pin FPC" doesn't uniquely identify an ordering of pins (apparently some other orderings exist), doesn't explain things as well for the user (who, if anything, knows their product is a DPI kippah/panel combo), and actually doesn't have to exist (one could connect the 28 GPIOs directly to something else). Simply "DPI" seems like a good compromise name to distinguish from the HDMI, DSI, and TV connectors . Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

The "device dax" implementation was revised this week in response to review feedback, and to address failures detected by the recently expanded ndctl unit test suite. Not included in this pull request are two dax topic branches (dax error handling, and dax radix-tree locking). These topics were deferred to get a few more days of -next integration testing, and to coordinate a branch baseline with Ted and the ext4 tree. Vishal and Ross will send the error handling and locking topics respectively in the next few days. This branch has received a positive build result from the kbuild robot across 226 configs. Summary: - Device DAX for persistent memory: Device DAX is the device-centric analogue of Filesystem DAX (CONFIG_FS_DAX). It allows memory ranges to be allocated and mapped without need of an intervening file system. Device DAX is strict, precise and predictable. Specifically this interface: a) Guarantees fault granularity with respect to a given page size (pte, pmd, or pud) set at configuration time. b) Enforces deterministic behavior by being strict about what fault scenarios are supported. Persistent memory is the first target, but the mechanism is also targeted for exclusive allocations of performance/feature differentiated memory ranges. - Support for the HPE DSM (device specific method) command formats.

It is also clear that future platform generations (ACPI or not) will continue to revise and extend the DIMM command set as new devices and use cases arrive. It is obviously untenable to continue to proliferate divergence of these command definitions, and to that end a standardization process has begun to provide for a unified specification. However, that leaves a problem about what to do with this first generation where vendors are already shipping divergence. The Linux kernel can support these initial diverged platforms without giving platform-firmware free reign to continue to diverge and compound kernel maintenance overhead. The kernel implementation can encourage standardization in two ways: 1/ Require that any function code that userspace wants to send be explicitly white-listed in the implementation. For ACPI this means function codes marked as supported by acpi_check_dsm() may only be invoked if they appear in the white-list. A function must be publicly documented before it is added to the white-list. 2/ The above restrictions can be trivially bypassed by using the "vendor-specific" payload command. However, since vendor-specific commands are by definition not publicly documented and have the potential to corrupt the kernel's view of the dimm state, we provide a toggle to disable vendor-specific operations. Enabling undefined behavior is a policy decision that can be made by the platform owner and encourages firmware implementations to choose public over private command implementations.

Features * core - convenience functions to claim / release direct access to the device. Makes more consistent handling of this corner easier. Used in ad7192 driver. * ak8975 - power regulator support. * at91-sama5d2 - differential channel support. * mma8452 - runtime pm support - drop device specific autosleep and use the runtime pm one instead. * ms5611 - DT bindings - oversampling ratio support Cleanups and minor fixes * MAINTAINERS - Peter got married - hence name change! * Documentation - Fix a typo in in_proximity_raw description. - Add some missing docs for iio_buffer_access_funcs. * Tools - update iio_event_monitor names to match new stuff. - make generic_buffer look for triggers ending in -trigger as we let these in for a number of drivers a long time back and now it is a fairly common option. Drivers * staging wide - convert bare unsigned usage to unsigned int to comply with coding style. * non staging wide: - since boiler plate gpio handling of interrupts has been moved into the ACPI core we don't need to include gpio/consumer.h in a load of drivers so drop it. * ad7606 - fix an endian casting sparse warning. * ak8975 - fix a possible unitialized warning from gcc. - drop and unused field left over from earlier cleanups - fix a missing regulator_disable on exit. * at91-sama5d2 - typo and indentation - missing IOMEM dependency. - cleanup mode register usage by avoidling erasing whole thing when changing the sampling frequency. * bmc150 - use the core demux and available_scan_masks to simplify buffer handling - optimize the transfers in the trigger handler now we have a magic function to emulate bulk reads (under circumstances met here). This matters with some rather dumb i2c adapters in particular. - use a single regmap_conf for all bus types as they were all the same. * bmg160 - use the core demux and available_scan_masks to simplify the buffer handling - optimize the transfers in the trigger handler now we have a magic funciton to emulate bulk rads (under circumstances met here). - drop gpio interrupt probing from the driver (ACPI) as now handled by the ACPI core. * ina2xx-adc - update the CALIB register when RShunt changes. - fix scale for VShunt - in reality this error canceled out when used. * isl29028 - use regmap to retrieve the struct device instead of carrying a second copy of it around. * kxcjk-1013 - use core demux - optimize i2c transfers in the trigger handler. * mcp4531 - refactor to use a pointer to access model parameters instead of indexing into the array each time. * mma8452 - style fixes - avoid swtiching to active whenever the config changes - add missin i2c_device_id for mma8451 * mpu6050 - fix possible NULL dereference. - fix the name / chip_id used when ACPI used (otherwise reports as NULL). * ms5611 - fix a missing regulator_disable that left the regulator on during removal. * mxc4005 - drop gpio interrupt handling for ACPI case from driver as the core now handles this case. * st-sensors - note that there are only ever a maximum of 3 axis on current st-sensors so just allocate a fixed sized buffer big enough for that. * tpl0102 - change the i2c_check_functionality condition to bring it inline with other IIO users as EOPNOTSUPP. * tsl2563 - replace deprecated flush_scheduled_work
