2021-04-08dt-bindings: arm: Convert nuvoton,npcm750 binding to YAMLJonathan Neuschäfer2-6/+23
The general trend is to have devicetree bindings in YAML format, to allow automatic validation of bindings and devicetrees. Convert the NPCM SoC family's binding to YAML before it accumulates more entries. The nuvoton,npcm750-evb compatible string is introduced to keep the structure of the binding a little simpler.

2021-04-07Documentation: kunit: add tips for using current->kunit_testDaniel Latypov1-2/+76
As of commit 359a376081d4 ("kunit: support failure from dynamic analysis tools"), we can use current->kunit_test to find the current kunit test. Mention this in tips.rst and give an example of how this can be used in conjunction with `test->priv` to pass around state and specifically implement something like mocking. There's a lot more we could go into on that topic, but given that example is already longer than every other "tip" on this page, we just point to the API docs and leave filling in the blanks as an exercise to the reader. Also give an example of kunit_fail_current_test().

2021-04-07vfio/mdev: Simplify driver registrationJason Gunthorpe1-4/+1
This is only done once, we don't need to generate code to initialize a structure stored in the ELF .data segment. Fill in the three required .driver members directly instead of copying data into them during mdev_register_driver(). Further the to_mdev_driver() function doesn't belong in a public header, just inline it into the two places that need it. Finally, we can now clearly see that 'drv' derived from dev->driver cannot be NULL, firstly because the driver core forbids it, and secondly because NULL won't pass through the container_of(). Remove the dead code.

2021-04-07vfio/mdev: Add missing typesafety around mdev_deviceJason Gunthorpe1-2/+2
The mdev API should accept and pass a 'struct mdev_device *' in all places, not pass a 'struct device *' and cast it internally with to_mdev_device(). Particularly in its struct mdev_driver functions, the whole point of a bus's struct device_driver wrapper is to provide type safety compared to the default struct device_driver. Further, the driver core standard is for bus drivers to expose their device structure in their public headers that can be used with container_of() inlines and '&foo->dev' to go between the class levels, and '&foo->dev' to be used with dev_err/etc driver core helper functions. Move 'struct mdev_device' to mdev.h Once done this allows moving some one instruction exported functions to static inlines, which in turns allows removing one of the two grotesque symbol_get()'s related to mdev in the core code.

Qualcomm ARM64 DT updates for 5.13 This extends the initial SM8350 description merged in v5.12 with CPUfreq, SMMU, UFS, RPMHPD, SPMI, USB and remoteproc support. It adds initial PMIC definitions for the 6 PMICs found on the MTP and it introduces the new SM8350 Hardware Development Kit (HDK). SC7180 is further polished, the DisplayPort portion of the QMP phy is defined and several new SKUs of the Trogdor devices are introduced. The new SC7280 platform is introduced, with RPMH, RPMHPD, RPMCC, SPMI, CPU idle, SMMU and watchdog defined. SDM845 gains the camera related nodes and some cleanups.

On a typical end product, a vendor may choose to secure some regions in the NAND memory which are supposed to stay intact between FW upgrades. The access to those regions will be blocked by a secure element like Trustzone. So the normal world software like Linux kernel should not touch these regions (including reading). So let's add a property for declaring such secure regions so that the drivers can skip touching them.

Binding covering the ad7150, ad7151 and ad7156 capacitance to digital convertors. The only difference between these is how many channels they have (1 or 2) Whilst it is clearly necessary to provide power to the part, we don't need to know the voltage or anything so if it is always on, there should be no need to have it specified in the binding.

2021-04-06vfio: Split creation of a vfio_device into init and register opsJason Gunthorpe1-11/+16
This makes the struct vfio_device part of the public interface so it can be used with container_of and so forth, as is typical for a Linux subystem. This is the first step to bring some type-safety to the vfio interface by allowing the replacement of 'void *' and 'struct device *' inputs with a simple and clear 'struct vfio_device *' For now the self-allocating vfio_add_group_dev() interface is kept so each user can be updated as a separate patch. The expected usage pattern is driver core probe() function: my_device = kzalloc(sizeof(*mydevice)); vfio_init_group_dev(&my_device->vdev, dev, ops, mydevice); /* other driver specific prep */ vfio_register_group_dev(&my_device->vdev); dev_set_drvdata(dev, my_device); driver core remove() function: my_device = dev_get_drvdata(dev); vfio_unregister_group_dev(&my_device->vdev); /* other driver specific tear down */ kfree(my_device); Allowing the driver to be able to use the drvdata and vfio_device to go to/from its own data. The pattern also makes it clear that vfio_register_group_dev() must be last in the sequence, as once it is called the core code can immediately start calling ops. The init/register gap is provided to allow for the driver to do setup before ops can be called and thus avoid races.

2021-04-06pata_legacy: Add `probe_mask' parameter like with ide-genericMaciej W. Rozycki1-0/+11
Carry the `probe_mask' parameter over from ide-generic to pata_legacy so that there is a way to prevent random poking at ISA port I/O locations in attempt to discover adapter option cards with libata like with the old IDE driver. By default all enabled locations are tried, however it may interfere with a different kind of hardware responding there. For example with a plain (E)ISA system the driver tries all the six possible locations: scsi host0: pata_legacy ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100 ata1.00: 19541088 sectors, multi 16: LBA ata1.00: configured for PIO scsi 0:0:0:0: Direct-Access ATA ST310211A 3.54 PQ: 0 ANSI: 5 scsi 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] 19541088 512-byte logical blocks: (10.0 GB/9.32 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk scsi host1: pata_legacy ata2: PATA max PIO4 cmd 0x170 ctl 0x376 irq 15 scsi host1: pata_legacy ata3: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11 scsi host1: pata_legacy ata4: PATA max PIO4 cmd 0x168 ctl 0x36e irq 10 scsi host1: pata_legacy ata5: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8 scsi host1: pata_legacy ata6: PATA max PIO4 cmd 0x160 ctl 0x366 irq 12 however giving the kernel "pata_legacy.probe_mask=21" makes it try every other location only: scsi host0: pata_legacy ata1: PATA max PIO4 cmd 0x1f0 ctl 0x3f6 irq 14 ata1.00: ATA-4: ST310211A, 3.54, max UDMA/100 ata1.00: 19541088 sectors, multi 16: LBA ata1.00: configured for PIO scsi 0:0:0:0: Direct-Access ATA ST310211A 3.54 PQ: 0 ANSI: 5 scsi 0:0:0:0: Attached scsi generic sg0 type 0 sd 0:0:0:0: [sda] 19541088 512-byte logical blocks: (10.0 GB/9.32 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: sda1 sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk scsi host1: pata_legacy ata2: PATA max PIO4 cmd 0x1e8 ctl 0x3ee irq 11 scsi host1: pata_legacy ata3: PATA max PIO4 cmd 0x1e0 ctl 0x3e6 irq 8 Signed-off-by: Maciej W.

This patch is not a compatible change, but we must do this modifaction because MediaTek IOMMU add the device_link between the smi-larb device and venc_device, if the venc device call the pm_runtime_get_sync, the smi-larb's pm_runtime_get_sync also be called automatically.
