The previous commit adding new sysfs for keyboard language has warning and few code correction has to be done as per new review comments. Below changes has been addressed in this version: - corrected warning. Many thanks to kernel test robot <lkp@intel.com> for reporting and determining this warning. - used sysfs_emit_at() API instead of strcat. - sorted keyboard language array. - removed unwanted space and corrected sentences.

2021-02-02ALSA: jack: implement software jack injection via debugfsHui Wang2-0/+167
This change adds audio jack injection feature through debugfs, with this feature, we could validate alsa userspace changes by injecting plugin or plugout events to the non-phantom audio jacks. With this change, the sound core will build the folders $debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled. And if users also enable the SND_JACK_INJECTION_DEBUG, the jack injection nodes will be built in the folder cardN like below: $tree $debugfs_mount_dir/sound $debugfs_mount_dir/sound ├── card0 │   ├── HDMI_DP_pcm_10_Jack │   │   ├── jackin_inject │   │   ├── kctl_id │   │   ├── mask_bits │   │   ├── status │   │   ├── sw_inject_enable │   │   └── type ... │   └── HDMI_DP_pcm_9_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type └── card1 ├── HDMI_DP_pcm_5_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type ... ├── Headphone_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type └── Headset_Mic_Jack ├── jackin_inject ├── kctl_id ├── mask_bits ├── status ├── sw_inject_enable └── type The nodes kctl_id, mask_bits, status and type are read-only, users could check jack or jack_kctl's information through them. The nodes sw_inject_enable and jackin_inject are directly used for injection. The sw_inject_enable is read-write, users could check if software injection is enabled or not on this jack, and users could echo 1 or 0 to enable or disable software injection on this jack. Once the injection is enabled, the jack will not change by hardware events anymore, once the injection is disabled, the jack will restore the last reported hardware events to the jack. The jackin_inject is write-only, if the injection is enabled, users could echo 1 or 0 to this node to inject plugin or plugout events to this jack. For the detailed usage information on these nodes, please refer to Documentation/sound/designs/jack-injection.rst.

2021-02-01usb: typec: Provide PD Specification Revision for cable and partnerBenson Leung1-0/+13
The USB Power Delivery specification Section 6.2.1.1.5 outlines revision backward compatibility requirements starting from Revision 3.0. The Port, the Cable Plug, and the Port Partner may support either revision 2 or revision 3 independently, and communication between ports, partners, and cables of different revisions are allowed under rules that the parties agree to communicate between each other using the lowest common operating revision. This may mean that Port-to-Partner operating revision comms may be different than Port-to-CablePlug operating revision comms. For example, it is possible for a R3.0 port to communicate with a R3.0 partner using R3.0 messages, while the R3.0 port (in the same session) must communicate with the R2.0 cable using R2.0 messages only. Introduce individual revision number properties for cable and port partner so that the port can track them independently.

Add a resource-managed variant of blk_ksm_init() so that drivers don't have to worry about calling blk_ksm_destroy(). Note that the implementation uses a custom devres action to call blk_ksm_destroy() rather than switching the two allocations to be directly devres-managed, e.g. with devm_kmalloc(). This is because we need to keep zeroing the memory containing the keyslots when it is freed, and also because we want to continue using kvmalloc() (and there is no devm_kvmalloc()).

Document the compatible value for the Direct Memory Access Controller blocks in the Renesas R-Car V3U (R8A779A0) SoC. The most visible difference with DMAC blocks on other R-Car SoCs is the move of the per-channel registers to a separate register block.

2021-02-01kbuild: remove PYTHON variableMasahiro Yamada2-2/+2
Python retired in 2020, and some distributions do not provide the 'python' command any more. As in commit 51839e29cb59 ("scripts: switch explicitly to Python 3"), we need to use more specific 'python3' to invoke scripts even if they are written in a way compatible with both Python 2 and 3. This commit removes the variable 'PYTHON', and switches the existing users to 'PYTHON3'. BTW, PEP 394 (https://www.python.org/dev/peps/pep-0394/) is a helpful material.

2021-01-29net: dsa: allow changing the tag protocol via the "tagging" device attributeVladimir Oltean1-2/+9
Currently DSA exposes the following sysfs: $ cat /sys/class/net/eno2/dsa/tagging ocelot which is a read-only device attribute, introduced in the kernel as commit 98cdb4807123 ("net: dsa: Expose tagging protocol to user-space"), and used by libpcap since its commit 993db3800d7d ("Add support for DSA link-layer types"). It would be nice if we could extend this device attribute by making it writable: $ echo ocelot-8021q > /sys/class/net/eno2/dsa/tagging This is useful with DSA switches that can make use of more than one tagging protocol. It may be useful in dsa_loop in the future too, to perform offline testing of various taggers, or for changing between dsa and edsa on Marvell switches, if that is desirable. In terms of implementation, drivers can support this feature by implementing .change_tag_protocol, which should always leave the switch in a consistent state: either with the new protocol if things went well, or with the old one if something failed. Teardown of the old protocol, if necessary, must be handled by the driver. Some things remain as before: - The .get_tag_protocol is currently only called at probe time, to load the initial tagging protocol driver. Nonetheless, new drivers should report the tagging protocol in current use now. - The driver should manage by itself the initial setup of tagging protocol, no later than the .setup() method, as well as destroying resources used by the last tagger in use, no earlier than the .teardown() method. For multi-switch DSA trees, error handling is a bit more complicated, since e.g. the 5th out of 7 switches may fail to change the tag protocol. When that happens, a revert to the original tag protocol is attempted, but that may fail too, leaving the tree in an inconsistent state despite each individual switch implementing .change_tag_protocol transactionally. Since the intersection between drivers that implement .change_tag_protocol and drivers that support D in DSA is currently the empty set, the possibility for this error to happen is ignored for now.
