2021-12-16soc/tegra: Enable runtime PM during OPP state-syncingDmitry Osipenko
GENPD core now can set up domain's performance state properly while device is RPM-suspended. Runtime PM of a device must be enabled during setup because GENPD checks whether device is suspended and check doesn't work while RPM is disabled. Instead of replicating the boilerplate RPM-enable code around OPP helper for each driver, let's make OPP helper to take care of enabling it.

2021-12-16soc/tegra: pmc: Add reboot notifierJon Hunter
The Tegra PMC driver implements a restart handler that supports Tegra specific reboot commands such as placing the device into 'recovery' mode in order to reprogram the platform. This is accomplished by setting the appropriate bit in the PMC scratch0 register prior to rebooting the platform. For Tegra platforms that support PSCI or EFI, the default Tegra restart handler is not called and the PSCI or EFI restart handler is called instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra specific reboot commands do not currently work. Fix this by moving the code that programs the PMC scratch0 register into a separate reboot notifier that will always be called on reboot.

2021-12-16soc/tegra: Don't print error message when OPPs not availableDmitry Osipenko
Previously we assumed that devm_tegra_core_dev_init_opp_table() will be used only by drivers that will always have device with OPP table, but this is not true anymore. For example now Tegra30 will have OPP table for PWM, but Tegra20 not and both use the same driver. Hence let's not print the error message about missing OPP table in the common helper, we can print it elsewhere.

2021-12-16iio: iio_device_alloc(): Remove unnecessary self drvdataLars-Peter Clausen
Drvdata is typically used by drivers to attach driver specific data to a device. It is used to retrieve driver specific information when only the device to which the data is attached is available. In the IIO core in the `iio_device_alloc()` function we call `iio_device_set_drvdata(indio_dev, indio_dev)`. This sets the drvdata of the IIO device to itself. This is rather unnecessary since if we have a pointer to the IIO device to call `iio_device_get_drvdata()` on it we don't need to call the function since we already have the pointer. If we only have a pointer to the `struct device` we can use `dev_to_iio_dev()` to get the IIO device from it. Furthermore the drvdata is supposed to be reserved for drivers, so it should not be used by the IIO core in the first place. The `set_drvdata()` has been around from the very beginning of the IIO framework and back then it was used in the IIO device sysfs attribute handling code. But that was subsequently replaced with a `dev_to_iio_dev()` in commit e53f5ac52ec1 ("iio: Use dev_to_iio_dev()") and other cleanups. The self `set_drvdata()` is now no longer needed and can be removed. Verified that there no longer any users by checking for potential users using the following two coccinelle scripts and reviewing that none of the matches are problematic code. <smpl> @@ struct iio_dev *iio_dev; expression dev; identifier fn !~ "(remove|resume|suspend)"; @@ fn(...) { ... *iio_dev = dev_get_drvdata(dev) ... } </smpl> <smpl> @r1@ position p; struct iio_dev *indio_dev; identifier dev_fn =~ "^dev_"; identifier devm_fn =~ "^devm_"; @@ ( dev_fn | devm_fn ) (&indio_dev@p->dev, ...) @@ struct iio_dev *indio_dev; position p != r1.p; @@ *&indio_dev@p->dev</smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2021-12-16net: prestera: flower template supportVolodymyr Mytnyk
Add user template explicit support. At this moment, max TCAM rule size is utilized for all rules, doesn't matter which and how much flower matches are provided by user. It means that some of TCAM space is wasted, which impacts the number of filters that can be offloaded. Introducing the template, allows to have more HW offloaded filters by specifying the template explicitly. Example: tc qd add dev PORT clsact tc chain add dev PORT ingress protocol ip \ flower dst_ip 0.0.0.0/16 tc filter add dev PORT ingress protocol ip \ flower skip_sw dst_ip 1.2.3.4/16 action drop NOTE: chain 0 is the default chain id for "tc chain" & "tc filter" command, so it is omitted in the example above. This patch adds only template support for default chain 0 suppoerted by prestera driver at this moment. Chains are not supported yet, and will be added later.

2021-12-16gve: Add optional metadata descriptor type GVE_TXD_MTDWillem de Bruijn
Allow drivers to pass metadata along with packet data to the device. Introduce a new metadata descriptor type * GVE_TXD_MTD This descriptor is optional. If present it immediate follows the packet descriptor and precedes the segment descriptor. This descriptor may be repeated. Multiple metadata descriptors may follow. There are no immediate uses for this, this is for future proofing. At present devices allow only 1 MTD descriptor. The lower four bits of the type_flags field encode GVE_TXD_MTD. The upper four bits of the type_flags field encodes a *sub*type. Introduce one such metadata descriptor subtype * GVE_MTD_SUBTYPE_PATH This shares path information with the device for network failure discovery and robust response: Linux derives ipv6 flowlabel and ECMP multipath from sk->sk_txhash, and updates this field on error with sk_rethink_txhash. Allow the host stack to do the same. Pass the tx_hash value if set. Also communicate whether the path hash is set, or more exactly, what its type is. Define two common types GVE_MTD_PATH_HASH_NONE GVE_MTD_PATH_HASH_L4 Concrete examples of error conditions that are resolved are mentioned in the commits that add sk_rethink_txhash calls. Such as commit 7788174e8726 ("tcp: change IPv6 flow-label upon receiving spurious retransmission"). Experimental results mirror what the theory suggests: where IPv6 FlowLabel is included in path selection (e.g., LAG/ECMP), flowlabel rotation on TCP timeout avoids the vast majority of TCP disconnects that would otherwise have occurred during link failures in long-haul backbones, when an alternative path is available. Rotation can be applied to various bad connection signals, such as timeouts and spurious retransmissions. In aggregate, such flow level signals can help locate network issues.

This is simpler than having both an ice_devlink_flash_update and an ice_flash_pldm_image. It will make additions like dry-run easier in the future. * reducing time to read Option ROM version information. * adding support for firmware activation via devlink reload, when possible.

2021-12-16drm/format-helper: Add drm_fb_xrgb8888_to_xrgb2101010_toio()Hector Martin
Add XRGB8888 emulation support for devices that can only do XRGB2101010. This is chiefly useful for simpledrm on Apple devices where the bootloader-provided framebuffer is 10-bit.

2021-12-16of: Move simple-framebuffer device handling from simplefb to ofHector Martin
This code is required for both simplefb and simpledrm, so let's move it into the OF core instead of having it as an ad-hoc initcall in the drivers.

2021-12-16rtc: gamecube: Report low battery as invalid dataEmmanuel Gil Peyrot
I haven’t been able to test this patch as all of my consoles have a working RTC battery, but according to the documentation it should work like that.

2021-12-16rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii UEmmanuel Gil Peyrot
These three consoles share a device, the MX23L4005, which contains a clock and 64 bytes of SRAM storage, and is exposed on the EXI bus (similar to SPI) on channel 0, device 1. This driver allows it to be used as a Linux RTC device, where time can be read and set. The hardware also exposes two timers, one which shuts down the console and one which powers it on, but these aren’t supported currently. On the Wii U, the counter bias is stored in a XML file, /config/rtc.xml, encrypted in the SLC (eMMC storage), using a proprietary filesystem. In order to avoid having to implement all that, this driver assumes a bootloader will parse this XML file and write the bias into the SRAM, at the same location the other two consoles have it.

2021-12-16drm/bridge: lvds-codec: Add support for pixel data sampling edge selectMarek Vasut
The OnSemi FIN3385 Parallel-to-LVDS encoder has a dedicated input line to select input pixel data sampling edge. Add DT property "pclk-sample", not the same as the one used by display timings but rather the same as used by media, and configure bus flags based on this DT property.
