This is a hack to change the USB class/subclass/protocol for the RNDIS USB gadget function. According to [1], this is "RNDIS over Ethernet". This configuration is recognized by rndiscmp.inf in Windows so that the correct driver loads without the need for a custom signed .inf. Furthermore, it is ignored on macOS and Linux (so we can use CDC/ECM instead). [1]: http://www.usb.org/developers/defined_class/#BaseClassEFh

ADC channel 0 photodiode detects both infrared + visible light, but ADC channel 1 just detects infrared. However, the latter is a bit more sensitive in that range so complete darkness or low light causes a error condition in which the chan0 - chan1 is negative that results in a -EAGAIN. This patch changes the resulting lux1_input sysfs attribute message from "Resource temporarily unavailable" to a user-grokable lux value of 0. Signed-off-by: Matt Ranostay <[email protected]>

Some applications require applying the same overlay to a different target according to some external condition (for instance depending on the slot a card has been inserted, the overlay target is different). The indirect target use requires using the new of_overlay_create_indirect() API which uses a text selector. The format requires the use of a target-indirect node as follows: fragment@0 { target-indirect { foo { target = <&foo_target>; }; bar { target = <&bar_target>; }; }; }; Calling of_overlay_create_indirect() with a "foo" argument selects the foo_target and so on.

The target facility of an overlay allows the target to be any point in the live kernel tree, since it usually that's required when creating overlays for internal SoC devices.

This probably misplaced (in drivers/misc) patch allows use of device tree overlays on the two kinds of probeable busses that count nowadays, PCI & USB. It does so by dynamically creating device nodes for the busses & devices that are probed and according to user-configuration applying an overlay when they appear.

Ethernet drivers implementing both {GS}RXFH and {GS}CHANNELS ethtool ops incorrectly allow SCHANNELS when it would conflict with the settings from SRXFH. This occurs because it is not possible for drivers to understand whether their Rx flow indirection table has been configured or is in the default state. In addition, drivers currently behave in various ways when increasing the number of Rx channels. Some drivers will always destroy the Rx flow indirection table when this occurs, whether it has been set by the user or not. Other drivers will attempt to preserve the table even if the user has never modified it from the default driver settings. Neither of these situation is desirable because it leads to unexpected behavior or loss of user configuration. The correct behavior is to simply return -EINVAL when SCHANNELS would conflict with the current Rx flow table settings. However, it should only do so if the current settings were modified by the user. If we required that the new settings never conflict with the current (default) Rx flow settings, we would force users to first reduce their Rx flow settings and then reduce the number of Rx channels. This patch proposes a solution implemented in net/core/ethtool.c which ensures that all drivers behave correctly. It checks whether the RXFH table has been configured to non-default settings, and stores this information in a private netdev flag. When the number of channels is requested to change, it first ensures that the current Rx flow table is not going to assign flows to now disabled channels.

This patch implements sub command ETHTOOL_GCOALESCE for ioctl ETHTOOL_PERQUEUE. It introduces an interface get_per_queue_coalesce to get coalesce of each masked queue from device driver. Then the interrupt coalescing parameters will be copied back to user space one by one.

This patch implements sub command ETHTOOL_SCOALESCE for ioctl ETHTOOL_PERQUEUE. It introduces an interface set_per_queue_coalesce to set coalesce of each masked queue to device driver. The wanted coalesce information are stored in "data" for each masked queue, which can copy from userspace. If it fails to set coalesce to device driver, the value which already set to specific queue will be tried to rollback.

This patch defines a new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API, handled by the new get_link_ksettings/set_link_ksettings callbacks. This API provides support for most legacy ethtool_cmd fields, adds support for larger link mode masks (up to 4064 bits, variable length), and removes ethtool_cmd deprecated fields (transceiver/maxrxpkt/maxtxpkt). This API is deprecating the legacy ETHTOOL_GSET/SSET API and provides the following backward compatibility properties: - legacy ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks. - legacy ethtool with new get/set_link_ksettings drivers: the new driver callbacks are used, data internally converted to legacy ethtool_cmd. ETHTOOL_GSET will return only the 1st 32b of each link mode mask. ETHTOOL_SSET will fail if user tries to set the ethtool_cmd deprecated fields to non-0 (transceiver/maxrxpkt/maxtxpkt). A kernel warning is logged if driver sets higher bits. - future ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks, internally converted to new data structure. Deprecated fields (transceiver/maxrxpkt/maxtxpkt) will be ignored and seen as 0 from user space. Note that that "future" ethtool tool will not allow changes to these deprecated fields. - future ethtool with new drivers: direct call to the new callbacks. By "future" ethtool, what is meant is: - query: first try ETHTOOL_GLINKSETTINGS, and revert to ETHTOOL_GSET if fails - set: query first and remember which of ETHTOOL_GLINKSETTINGS or ETHTOOL_GSET was successful + if ETHTOOL_GLINKSETTINGS was successful, then change config with ETHTOOL_SLINKSETTINGS. A failure there is final (do not try ETHTOOL_SSET). + otherwise ETHTOOL_GSET was successful, change config with ETHTOOL_SSET. A failure there is final (do not try ETHTOOL_SLINKSETTINGS). The interaction user/kernel via the new API requires a small ETHTOOL_GLINKSETTINGS handshake first to agree on the length of the link mode bitmaps. If kernel doesn't agree with user, it returns the bitmap length it is expecting from user as a negative length (and cmd field is 0). When kernel and user agree, kernel returns valid info in all fields (ie. link mode length > 0 and cmd is ETHTOOL_GLINKSETTINGS). Data structure crossing user/kernel boundary is 32/64-bit agnostic. Converted internally to a legal kernel bitmap. The internal __ethtool_get_settings kernel helper will gradually be replaced by __ethtool_get_link_ksettings by the time the first "link_settings" drivers start to appear. So this patch doesn't change it, it will be removed before it needs to be changed. Signed-off-by: David Decotigny <[email protected]> Signed-off-by: David S. Miller <[email protected]>

When the ETHTOOL_GLINKSETTINGS implementation finds that userland is using the wrong number of words of link mode bitmaps (or is trying to find out the right numbers) it sets the cmd field to 0 in the response structure. This is inconsistent with the implementation of every other ethtool command, so let's remove that inconsistency before it gets into a stable release.

The Modio cape exposes 4 UARTs as 3xRS485 and 1xRS232 port on the BeagleBoneBlack. To function, it needs the cape manager to be disabled, since the capemanager shares pins with one of the UART devices. This device tree file is based on the minimal dts file. It currently sets up RTS pins as GPIO pins, which the OMAP_SERIAL driver can function with. So far, I have not managed to make the driver simply set the RTS flag in order to control the port.

Commit 520bd7a ("mmc: core: Optimize boot time by detecting cards simultaneously") causes regressions for some platforms. These platforms relies on fixed mmcblk device indexes, instead of deploying the defacto standard with UUID/PARTUUID. In other words their rootfs needs to be available at hardcoded paths, like /dev/mmcblk0p2. Such guarantees have never been made by the kernel, but clearly the above commit changes the behaviour. More precisely, because of that the order changes of how cards becomes detected, so do their corresponding mmcblk device indexes. As the above commit significantly improves boot time for some platforms (magnitude of seconds), let's avoid reverting this change but instead restore the behaviour of how mmcblk device indexes becomes picked. By using the same index for the mmcblk device as for the corresponding mmc host device, the probe order of mmc host devices decides the index we get for the mmcblk device. For those platforms that suffers from a regression, one could expect that this updated behaviour should be sufficient to meet their expectations of "fixed" mmcblk device indexes. Another side effect from this change, is that the same index is used for the mmc host device, the mmcblk device and the mmc block queue. That should clarify their relationship.

Reduce max_segs to 64, a value that allows allocation of an entire EDMA descriptor list within a single page - EDMA descriptors are 40 bytes and the header is much larger. This avoids doing a higher order GFP_ATOMIC allocation in edma_prep_slave_sg when setting up a transfer which can potentially fail due to fragmentation under heavy I/O load. The current value of 1024 is unusually high in comparison to other mmc host drivers which mostly use values of between 1 and 256. The EDMA driver at present splits lists above 20 segments in any case so reducing the size of lists we pass to it shouldn't add much overhead. rcn-ee: add use_adma option: https://www.spinics.net/lists/linux-omap/msg137942.html Signed-off-by: Will Newton <[email protected]> Signed-off-by: Robert Nelson <[email protected]>
