2025-05-01power: reset: syscon-reboot: add gs101-specific resetAndré Draszik
Linux supports a couple different reset modes, but this driver here doesn't distinguish between them and issues the same syscon register write irrespective of the reset mode requested by the kernel. Since DTs should not encode register writes (see e.g. [1]), update this driver to support different reset modes based on DT compatible match. At the same time, add support for Google GS101, which does support cold, hard, warm, and soft. As an example why this is useful, other than properly supporting the Linux reboot= kernel command line option or sysfs entry, this change allows gs101-platforms to default to a more secure cold-reset, but also to warm-reset in case RAM contents needs to be retained across the reset.

2025-04-29power: reset: add Toradex Embedded ControllerEmanuele Ghidoli
Toradex SMARC iMX8MP and SMARC iMX95 SoM modules use a small Embedded Controller (EC) to manage power and reset functions and related SMARC signals. This driver implements power-off and reboot handlers, communicating with the EC via I2C to issue the appropriate power management commands. During probe, the driver logs the Embedded Controller ID (unique ID for each SMARC board supported) in hex format along with the firmware version.

2025-04-28power: reset: reboot-mode: better compatibility with DT (replace ' ,/')André Draszik
This driver's purpose is to parse boot modes described in DT, via key (node name) / value pairs, and to match them to a reboot mode requested by the kernel. Unfortunately, DT node names can not contain certain characters, like space ' ' or comma ',' or slash '/', while the requested reboot mode may. This is a problem because it makes it impossible to match reboot modes containing any of those characters. For example, this makes it impossible to communicate DM verity errors to the boot loader - DM verity errors trigger a reboot with mode "dm-verity device corrupted" in drivers/md/dm-verity-target.c and devices typically have to take action in that case [1]. Changing this string itself is not feasible, see e.g. discussion in [2], but would also just cover this one case. Another example is Android, which may use comma in the reboot mode string, e.g. as "shutdown,thermal" in [3]. The kernel also shouldn't prescribe what characters are allowed inside the boot mode string for a user to set. It hasn't done this so far, and introducing such a restriction would be an interface break and arbitrarily enforce a random new policy. Therefore, update this driver to do another round of string matching, after replacing the common characters mentioned above with dash '-', if a match hasn't been found without doing said replacement. This now allows us to have DT entries of e.g.: mode-dm-verity-device-corrupted = <...> and so on.

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier. There is also no real benefit in printing errors on missing syscon argument, because this is done just too late: runtime check on static/build-time data. Dtschema and Devicetree bindings offer the static/build-time check for this already.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/power/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

Use this helper to register sys_off handler. Drivers should move away from setting pm_power_off directly as it only allows for one handler. The new way allows for trying multiple if the first one doesn't work.
