HelloThis seems exactly what I would need on the mc13783 to handle cleanly the poweroff,
but after reading this patchset I have the following question: [...]
+/* + * Notifier list for kernel code which wants to be called + * to power off the system. + */ +static ATOMIC_NOTIFIER_HEAD(poweroff_handler_list);
[...]
+void do_kernel_poweroff(void) +{ + atomic_notifier_call_chain(&poweroff_handler_list, 0, NULL); +} +
It seems that the poweroff callback needs to be atomic as per _atomic_notifier_call_chain documentation: "Calls each function in a notifier chain in turn. The functions run in an atomic context" But this is a problem for many MFD (mc13783, twl4030 etc ...) which are accessible on only a blocking bus (SPI, I2C). What I am missing here ?
