mailbox: qcom-apcs-ipc: Assign OF node to clock controller child device

2025-05-29T15:01:35Z

Currently, the child device for the clock controller inside the APCS block is created without any OF node assigned, so the drivers need to rely on the parent device for obtaining any resources. Add support for defining the clock controller inside a "clock-controller" subnode to break up circular dependencies between the mailbox and required parent clocks of the clock controller. For backwards compatibility, if the subnode is not defined, reuse the OF node from the parent device. Signed-off-by: Stephan Gerhold Reviewed-by: Dmitry Baryshkov Signed-off-by: Jassi Brar

mailbox: Remove devm_mbox_controller_unregister

2025-05-26T21:23:39Z

Commit e898d9cdd3a9("mailbox: Add device-managed registration functions") introduced device-managed API for mailbox, but in the past 7 years, there is no user for devm_mbox_controller_unregister. So remove it. Signed-off-by: Peng Fan Signed-off-by: Jassi Brar

mailbox: Propagate correct error return value

2025-05-26T21:23:39Z

In case of_property_match_string fails, it makes more sense to return its error value to caller, not force the value to ERR_PTR(-EINVAL). Signed-off-by: Peng Fan Signed-off-by: Jassi Brar

mailbox: Not protect module_put with spin_lock_irqsave

2025-05-26T21:23:39Z

&chan->lock is not supposed to protect 'chan->mbox'. And in __mbox_bind_client, try_module_get is also not protected by &chan->lock. So move module_put out of the lock protected region. Signed-off-by: Peng Fan Signed-off-by: Jassi Brar

mailbox: Use dev_err when there is error

2025-05-26T21:23:39Z

Use dev_err to show the error log instead of using dev_dbg. Signed-off-by: Peng Fan Signed-off-by: Jassi Brar
