If the gpio DT node has the 'gpio-ranges' property, the range will be added by the gpio core and doesn't need to be added by the pinctrl driver. By having the gpio-ranges property, we can map every pin between gpio node and pinctrl node and we can stop using the deprecated pinctrl_add_gpio_range() function.

2020-12-07media: vivid: fix 'disconnect' error injectionHans Verkuil
The 'disconnect' error injection functionality suffered from bit rot. New device nodes were added without updating vivid_user_gen_s_ctrl(), so that function had to be updated for the new device nodes. Also, vivid didn't check if specific device nodes were actually ever created, so the vivid_is_last_user() would fail on that (it would return true instead of false in that case). Finally, selecting Disconnect, then unbind the vivid driver would fail since the remove() would think that the device nodes were already unregistered. Keep track of whether disconnect was pressed and re-register the device nodes in remove() before doing the real unregister.

2020-12-07media: rcar-vin: Mask VNCSI_IFMD registerJacopo Mondi
The VNCSI_IFMD register controls the data expansion mode and the channel routing between the CSI-2 receivers and VIN instances. According to the chip manual revision 2.20 not all fields are available for all the SoCs: - V3M, V3H and E3 do not support the DES1 field has they do not feature a CSI20 receiver. - D3 only supports parallel input, and the whole register shall always be written as 0. Inspect the per-SoC channel routing table where the available CSI-2 instances are reported and configure VNCSI_IFMD accordingly.

2020-12-07media: gspca: Fix memory leak in probeAlan Stern
The gspca driver leaks memory when a probe fails. gspca_dev_probe2() calls v4l2_device_register(), which takes a reference to the underlying device node (in this case, a USB interface). But the failure pathway neglects to call v4l2_device_unregister(), the routine responsible for dropping this reference. Consequently the memory for the USB interface and its device never gets released. This patch adds the missing function call.

For the latter category, the names use a components order convention that is the opposite of the first category, and the opposite of DRM pixel formats. This has led to lots of confusion in the past, and would really benefit from being explained more precisely. Do so, which also prepares for the addition of additional RGB pixels formats.

2020-12-07Revert "ACPI / resources: Use AE_CTRL_TERMINATE to terminate resources walks"Daniel Scally
This reverts commit 8a66790b7850a6669129af078768a1d42076a0ef. Switching this function to AE_CTRL_TERMINATE broke the documented behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in fact, terminate the resource walk because acpi_walk_resource_buffer() ignores it (specifically converting it to AE_OK), referring to that value as "an OK termination by the user function". This means that acpi_dev_get_resources() does not abort processing when the preproc function returns a negative value.

2020-12-07ACPI: scan: Add PNP0D80 to the _DEP exceptions listRafael J. Wysocki
The PNP0D80 ("Windows-compatible System Power Management Controller") device ID is used for identifying the special device object providing the LPI (Low-power S0 Idle) _DSM interface [1]. That device object does not supply any operation regions, but it appears in _DEP lists for other devices in the ACPI tables on some systems to enforce specific enumeration ordering that does not matter for Linux. For this reason, _DEP list entries pointing to the device object whose _CID returns PNP0D80 need not be taken into account as real operation region dependencies, so add that device ID to the list of device IDs for which the matching _DEP list entries should be ignored. Accordingly, update the function used for matching device IDs in that list to allow it to check _CID as well as _HID and rename it to acpi_info_matches_ids().

2020-12-07PM: ACPI: Refresh wakeup device power configuration every timeRafael J. Wysocki
When wakeup signaling is enabled for a bridge for the second (or every next) time in a row, its existing device wakeup power configuration may not match the new conditions. For example, some devices below it may have been put into low-power states and that changes the device wakeup power conditions or similar. This causes functional problems to appear on some systems (for example, because of it the Thunderbolt port on Dell Precision 5550 cannot detect devices plugged in after it has been suspended). For this reason, modify __acpi_device_wakeup_enable() to refresh the device wakeup power configuration of the target device on every invocation, not just when it is called for that device first time in a row.

2020-12-07PM: ACPI: PCI: Drop acpi_pm_set_bridge_wakeup()Rafael J. Wysocki
The idea behind acpi_pm_set_bridge_wakeup() was to allow bridges to be reference counted for wakeup enabling, because they may be enabled to signal wakeup on behalf of their subordinate devices and that may happen for multiple times in a row, whereas for the other devices it only makes sense to enable wakeup signaling once. However, this becomes problematic if the bridge itself is suspended, because it is treated as a "regular" device in that case and the reference counting doesn't work. For instance, suppose that there are two devices below a bridge and they both can signal wakeup. Every time one of them is suspended, wakeup signaling is enabled for the bridge, so when they both have been suspended, the bridge's wakeup reference counter value is 2. Say that the bridge is suspended subsequently and acpi_pci_wakeup() is called for it. Because the bridge can signal wakeup, that function will invoke acpi_pm_set_device_wakeup() to configure it and __acpi_pm_set_device_wakeup() will be called with the last argument equal to 1. This causes __acpi_device_wakeup_enable() invoked by it to omit the reference counting, because the reference counter of the target device (the bridge) is 2 at that time. Now say that the bridge resumes and one of the device below it resumes too, so the bridge's reference counter becomes 0 and wakeup signaling is disabled for it, but there is still the other suspended device which may need the bridge to signal wakeup on its behalf and that is not going to work. To address this scenario, use wakeup enable reference counting for all devices, not just for bridges, so drop the last argument from __acpi_device_wakeup_enable() and __acpi_pm_set_device_wakeup(), which causes acpi_pm_set_device_wakeup() and acpi_pm_set_bridge_wakeup() to become identical, so drop the latter and use the former instead of it everywhere.

The mv64x60 EDAC driver depends on CONFIG_MV64X60. But that symbol is not user-selectable, and the last code that selected it was removed with the C2K board support in 2018, see: 92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support") That means the driver is now dead code, so remove it.
