net: ipa: kill ipa_power_suspend_handler()

2024-02-27T10:24:04+00:00

Now that ipa_power_suspend_handler() is a trivial wrapper around ipa_interrupt_suspend_clear_all(), we can open-code it in the one place it's used, and get rid of the function. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: kill ipa_power_modem_queue_wake()

2024-02-02T04:50:36+00:00

All ipa_power_modem_queue_wake() does is call netif_wake_queue() on the modem netdev. There is no need to wrap that call in a trivial function (and certainly not one defined in "ipa_power.c"). So get rid of ipa_power_modem_queue_wake(), and replace its one caller with a direct call to netif_wake_queue(). Determine the netdev pointer to use from the private TX endpoint's netdev pointer.

net: ipa: kill ipa_power_modem_queue_active()

2024-02-02T04:50:36+00:00

All ipa_power_modem_queue_active() does now is call netif_wake_queue(). Just call netif_wake_queue() in the two places it's needed, and get rid of ipa_power_modem_queue_active().

net: ipa: kill ipa_power_modem_queue_stop()

2024-02-02T04:50:36+00:00

All ipa_power_modem_queue_stop() does now is call netif_stop_queue(). Just call netif_stop_queue() in the one place it's needed, and get rid of ipa_power_modem_queue_stop().

net: ipa: register IPA interrupt handlers directly

2023-01-06T06:03:14+00:00

Declare the microcontroller IPA interrupt handler publicly, and assign it directly in ipa_interrupt_config(). Make the SUSPEND IPA interrupt handler public, and rename it ipa_power_suspend_handler(). Assign it directly in ipa_interrupt_config() as well. This makes it unnecessary to do this in ipa_interrupt_add(). Make similar changes for removing IPA interrupt handlers. The next two patches will finish the cleanup, removing the add/remove functions and the handler array entirely. Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski

net: ipa: request IPA register values be retained

2022-02-03T16:03:43+00:00

In some cases, the IPA hardware needs to request the always-on subsystem (AOSS) to coordinate with the IPA microcontroller to retain IPA register values at power collapse. This is done by issuing a QMP request to the AOSS microcontroller. A similar request ondoes that request. We must get and hold the "QMP" handle early, because we might get back EPROBE_DEFER for that. But the actual request should be sent while we know the IPA clock is active, and when we know the microcontroller is operational.

net: ipa: rename "ipa_clock.c"

2021-08-22T08:44:17+00:00

Finally, rename "ipa_clock.c" to be "ipa_power.c" and "ipa_clock.h" to be "ipa_power.h". Signed-off-by: Alex Elder Signed-off-by: David S. Miller
