2021-03-07Input: exc3000 - factor out vendor data requestLucas Stach
Factor out the vendor data i2c request handling to make it reusable for other functions. Also don't cache the model and firmware version string in the device private data as we never use the cached version, but always read from the device.

2021-03-07Input: exc3000 - split MT event handling from IRQ handlerLucas Stach
Split out the multitouch event handling into its own function to allow other events to be handled in the IRQ handler without disturbing the MT handling. Now that things are separated a bit more, stop treating vendor data requests special by cehcking for a locked mutex, but just look at the event ID to figure out if the message is a MT report or a vendor data query reply.

The common cros-ec keymap has been defined as macros. This patch uses the macros to simply linux,keymap in cros-ec-keyboard.dtsi file. This patch also creates an alias for keyboard-controller to make it easier to override the keymap in board-specific dts later.

2021-02-22dt-bindings: input: Create macros for cros-ec keymapPhilip Chen
In Chrome OS, the keyboard matrix can be split to two groups: The keymap for the top row keys can be customized based on OEM preference, while the keymap for the other keys is generic/fixed across boards. This patch creates marcos for the keymaps of these two groups, making it easier to reuse the generic portion of keymap when we override the keymap in the board-specific dts for custom top row design.

2021-02-22Input: cros-ec-keyb - expose function row physical map to userspacePhilip Chen
The top-row keys in a keyboard usually have dual functionalities. E.g. A function key "F1" is also an action key "Browser back". Therefore, when an application receives an action key code from a top-row key press, the application needs to know how to correlate the action key code with the function key code and do the conversion whenever necessary. Since the userpace already knows the key scanlines (row/column) associated with a received key code. Essentially, the userspace only needs a mapping between the key row/column and the matching physical location in the top row. So, enhance the cros-ec-keyb driver to create such a mapping and expose it to userspace in the form of a function_row_physmap attribute. The attribute would be a space separated ordered list of row/column codes for the keys in the function row, in a left-to-right order. The attribute will only be present when the device has a custom design for the top-row keys.

2021-02-19Input: applespi - don't wait for responses to commands indefinitely.Ronald Tschalär
The response to a command may never arrive or it may be corrupted (and hence dropped) for some reason. While exceedingly rare, when it did happen it blocked all further commands. One way to fix this was to do a suspend/resume. However, recovering automatically seems like a nicer option. Hence this puts a time limit (1 sec) on how long we're willing to wait for a response, after which we assume it got lost.

2021-02-12arm64: mte: Allow PTRACE_PEEKMTETAGS access to the zero pageCatalin Marinas
The ptrace(PTRACE_PEEKMTETAGS) implementation checks whether the user page has valid tags (mapped with PROT_MTE) by testing the PG_mte_tagged page flag. If this bit is cleared, ptrace(PTRACE_PEEKMTETAGS) returns -EIO. A newly created (PROT_MTE) mapping points to the zero page which had its tags zeroed during cpu_enable_mte(). If there were no prior writes to this mapping, ptrace(PTRACE_PEEKMTETAGS) fails with -EIO since the zero page does not have the PG_mte_tagged flag set. Set PG_mte_tagged on the zero page when its tags are cleared during boot. In addition, to avoid ptrace(PTRACE_PEEKMTETAGS) succeeding on !PROT_MTE mappings pointing to the zero page, change the __access_remote_tags() check to (vm_flags & VM_MTE) instead of PG_mte_tagged.

2021-02-12btrfs: initialize fs_info::csum_size earlier in open_ctreeSu Yue
User reported that btrfs-progs misc-tests/028-superblock-recover fails: [TEST/misc] 028-superblock-recover unexpected success: mounted fs with corrupted superblock test failed for case 028-superblock-recover The test case expects that a broken image with bad superblock will be rejected to be mounted. However, the test image just passed csum check of superblock and was successfully mounted. Commit 55fc29bed8dd ("btrfs: use cached value of fs_info::csum_size everywhere") replaces all calls to btrfs_super_csum_size by fs_info::csum_size. The calls include the place where fs_info->csum_size is not initialized. So btrfs_check_super_csum() passes because memcmp() with len 0 always returns 0. Fix it by caching csum size in btrfs_fs_info::csum_size once we know the csum type in superblock is valid in open_ctree().
