From 380d2b2d5a0491e47dfa250b40e3d849a922871d Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Fri, 28 May 2021 02:54:00 +0300 Subject: regulator: core: Add regulator_sync_voltage_rdev() Some NVIDIA Tegra devices use a CPU soft-reset method for the reboot and in this case we need to restore the coupled voltages to the state that is suitable for hardware during boot. Add new regulator_sync_voltage_rdev() helper which is needed by regulator drivers in order to sync voltage of a coupled regulators.

regulator found on boards based on MediaTek MT6779 and probably other SoCs. It is a so called pmic and connects as a slave to SoC using SPI, wrapped inside the pmic-wrapper.

reboot: Add hardware protection power-off There can be few cases when we need to shut-down the system in order to protect the hardware. Currently this is done at least by the thermal core when temperature raises over certain limit. Some PMICs can also generate interrupts for example for over-current or over-voltage, voltage drops, short-circuit, ... etc. On some systems these are a sign of hardware failure and only thing to do is try to protect the rest of the hardware by shutting down the system. Add shut-down logic which can be used by all subsystems instead of implementing the shutdown in each subsystem. The logic is stolen from thermal_core with difference of using atomic_t instead of a mutex in order to allow calls directly from IRQ context and changing the WARN() to pr_emerg() as discussed here: https://lore.kernel.org/lkml/YJuPwAZroVZ%2Fw633@alley/ and here: https://lore.kernel.org/linux-iommu/20210331093104.383705-4-geert+renesas@glider.be/ Signed-off-by: Matti Vaittinen Acked-by: Daniel Lezcano Link: https://lore.kernel.org/r/e83ec1ca9408f90c857ea9dcdc57b14d9037b03f.1622628333.git.matti.vaittinen@fi.rohmeurope.com Signed-off-by: Mark Brown --- include/linux/reboot.h | 1 + kernel/reboot.c | 79 ++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 80 insertions(+) (limited to 'include/linux') diff --git a/include/linux/reboot.h b/include/linux/reboot.h index 3734cd8f38a8..af907a3d68d1 100644 --- a/include/linux/reboot.h +++ b/include/linux/reboot.h @@ -79,6 +79,7 @@ extern char poweroff_cmd[POWEROFF_CMD_PATH_LEN]; extern void orderly_poweroff(bool force); extern void orderly_reboot(void); +void hw_protection_shutdown(const char *reason, int ms_until_forced); /* * Emergency restart, callable from an interrupt handler. diff --git a/kernel/reboot.c b/kernel/reboot.c index a6ad5eb2fa73..f7440c0c7e43 100644 --- a/kernel/reboot.c +++ b/kernel/reboot.c @@ -7,6 +7,7 @@ #define pr_fmt(fmt) "reboot: " fmt +#include #include #include #include @@ -518,6 +519,84 @@ void orderly_reboot(void) } EXPORT_SYMBOL_GPL(orderly_reboot); +/** + * hw_failure_emergency_poweroff_func - emergency poweroff work after a known delay + * @work: work_struct associated with the emergency poweroff function + * + * This function is called in very critical situations to force + * a kernel poweroff after a configurable timeout value. + */ +static void hw_failure_emergency_poweroff_func(struct work_struct *work) +{ + /* + * We have reached here after the emergency shutdown waiting period has + * expired.

Current regulator core notifications are used to inform consumers about errors where HW is misbehaving in such way it is assumed to be broken/unrecoverable. There are PMICs which are designed for system(s) that may have use for regulator indications sent before HW is damaged so that some board/consumer specific recovery-event can be performed while continuing most of the normal operations. Add new WARNING level events and notifications to be used for that purpose.

Move them from core.c to internal.h As the rdev print helpers use rdev_get_name() export it from core.c. Also move the declaration from coupler.h to driver.h because the rdev name is not just a coupled regulator property. I guess the main audience for rdev_get_name() will be the regulator core and drivers.
