| * | usb: gadget: OS Feature Descriptors supportLi Jun2021-01-313-1/+431

Microsoft hereby grants to You a nonexclusive, royalty-free, nontransferable, worldwide license under Microsoft鈥檚 patents embodied solely within the Specification and that are owned or licensable by Microsoft to make, use, import, offer to sell, sell and distribute directly or indirectly to Your Licensees Your Implementation. You may sublicense this patent license to Your Licensees under the same terms and conditions." The said extension is maintained by Microsoft for Microsoft. Yet it is fairly common for various devices to use it, and a popular proprietary operating system expects devices to provide "OS descriptors", so Linux-based USB gadgets whishing to be able to talk to a variety of operating systems should be able to provide the "OS descriptors". This patch adds optional support for gadgets whishing to expose the so called "OS Feature Descriptors", that is "Extended Compatibility ID" and "Extended Properties". Hosts which do request "OS descriptors" from gadgets do so during the enumeration phase and before the configuration is set with SET_CONFIGURATION. What is more, those hosts never ask for configurations at indices other than 0. Therefore, gadgets whishing to provide "OS descriptors" must designate one configuration to be used with this kind of hosts - this is what os_desc_config is added for in struct usb_composite_dev. There is an additional advantage to it: if a gadget provides "OS descriptors" and designates one configuration to be used with such non-USB-compliant hosts it can invoke "usb_add_config" in any order because the designated configuration will be reported to be at index 0 anyway. This patch also adds handling vendor-specific requests addressed at device or interface and related to handling "OS descriptors"."

| * | cmd: bcb: Add support for processing const string literals in bcb_set()Eugeniu Rosca2021-01-312-7/+14

However, since we recently exposed bcb_write_reboot_reason() API to be called by U-Boot fastboot, the idea is to be able to pass const string literals to this new BCB API, carrying the reboot reason. Since 'strsep' (just like its older/superseded sibling 'strtok') modifies the input string passed as parameter, BCB command in its current state would attempt to perform in-place modifications in a readonly string, which might lead to unexpected results. Fix the above with the cost of one dynamic memory allocation ('strdup'). This will also ensure no compiler warnings when passing string literals to bcb_write_reboot_reason().

| * | cros_ec: Add vstore supportSimon Glass2021-01-304-2/+202
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EC can store small amounts of data for the benefit of the verified boot process. Since the EC is seldom reset, this can allow the AP to store data that survives a reboot or a suspend/resume cycle. Add support for this. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | cros_ec: Allow use with of-platdataSimon Glass2021-01-301-0/+2
| | | | | | | | | | | | | | | | | | Avoid reading the device tree when of-platdata is in use. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | cros_ec: Show events in human-readable formSimon Glass2021-01-303-7/+112
| | | | | | | | | | | | | | | | | | | | | Add a command to show the current events as a list of names. This is easier to decipher than a bit mask. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | cros_ec: Add support for switchesSimon Glass2021-01-307-0/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | On x86 platforms the EC provides a way to read 'switches', which are on/off values determined by the EC. Add a new driver method for this and implement it for LPC. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | cros_ec: Add documentation for cros_ec driver operationsSimon Glass2021-01-301-0/+40
| | | | | | | | | | | | | | | | | | | | | Add comments to these methods so it is documented in this central place, not just in each driver. Signed-off-by: Simon Glass <sjg@chromium.org>
| * | cros_ec: Support reading EC featuresSimon Glass2021-01-306-10/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EC can support a variety of features and provides a way to find out what is available. Add support for this. Also update the feature list to the lastest available while we are here.

| * | cros_ec: Add support for reading the SKU IDSimon Glass2021-01-305-0/+55
| | | | | | | | | | | | | | | | | | | | | This allows reading strapping pins attached to the EC. Add an implementation for this. Signed-off-by: Simon Glass <sjg@chromium.org>
