* omap: mailbox: relax constraint to allow powerdomain to go to CSWRMiguel Vadillo2014-10-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | The mailbox registers can be accessed and configured by other remote processor initiators, and hence the driver has to be responsible for maintaining the register context when they are active. This is achieved by the mailbox driver by requesting a latency constraint on the power domain that it belongs to. The current constraint value (10) is high and restricts the power domain to remain in ON state as long as a remote processor is active. This value is relaxed to 400 to allow a lower power CSWR state that can still retain the context during cpuidle path and a remote processor is active. The constraint is completely removed when the remote processor is suspended. The mailbox context is saved and restored properly when suspending the remote processor.

* omap: mailbox: enable mailbox irq per instanceJuan Gutierrez2014-10-011-2/+0
| | | | | | | | | | | | | | | The machine-specific omap2_mbox_startup is called only once to initialize the whole mbox module. Enabling mbox irq at startup is only enabling the irq of the very first mailbox instance created. The enable_irq function should be called every time a new mbox instance is created, in the generic platform mailbox layer.

* omap: mbox: save, restore and off supportMiguel Vadillo2011-09-141-53/+77
| | | | | | | | | | | | | | | | | - Fix an issue related with the offsets of the registers - Each user (Ducati, Tesla ...) should not have its own ctx memory since the mbox module is one for all of them. A share ctx is created to store the needed registers when saving. - save_context function is saving just the irqs per user currently that is the only thing needed. - restore_context function is restoring just the irqs per user. mbox_startup function is setting all the rest of the register to the original state. - Add a pm_qos constraint when calling the first get and release it when the last put is calling, this is to support off mode.

| | | | | | | | | | | | | | | | The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.
