Re: [PATCH v25 06/10] power: reset: Add psci-reboot-mode driver

[sashiko-bot@kernel.org]

> PSCI supports different types of resets like SYSTEM_RESET, SYSTEM_RESET2
> ARCH WARM reset and SYSTEM_RESET2 vendor-specific resets. Currently
> there is no common driver that handles all supported psci resets at one
> place. Additionally, there is no common mechanism to issue the supported
> psci resets from userspace.
> 
> Add psci-reboot-mode as an auxiliary device created by the psci-devices
> driver. Define two types of PSCI resets, predefined-resets and
> vendor-specific resets.  Predefined-resets are defined by psci driver
> and vendor-specific resets are defined by SoC vendors, under the
> psci:reboot-mode node of SoC device tree.
> 
> Register the driver with the reboot-mode framework to interface these
> resets to userspace. When userspace initiates a supported command, pass
> the reset arguments to the PSCI driver to enable command-based reset.
> 
> This change allows userspace to issue supported PSCI reset commands
> using the standard reboot system calls while enabling SoC vendors to
> define their specific resets for PSCI.
