net: ipa: Remove redundant pm_runtime_mark_last_busy() calls

2025-10-30T01:55:56+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

net: ipa: call device_init_wakeup() earlier

2024-04-23T11:08:08+00:00

Currently, enabling wakeup for the IPA device doesn't occur until the setup phase of initialization (in ipa_power_setup()). There is no need to delay doing that, however. We can conveniently do it during the config phase, in ipa_interrupt_config(), where we enable power management wakeup mode for the IPA interrupt. Moving the device_init_wakeup() out of ipa_power_setup() leaves that function empty, so it can just be eliminated. Similarly, rearrange all of the matching inverse calls, disabling device wakeup in ipa_interrupt_deconfig() and removing that function as well. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: only enable the SUSPEND IPA interrupt when needed

2024-04-23T11:08:08+00:00

Only enable the SUSPEND IPA interrupt type when at least one endpoint has that interrupt enabled. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: maintain bitmap of suspend-enabled endpoints

2024-04-23T11:08:08+00:00

Keep track of which endpoints have the SUSPEND IPA interrupt enabled in a variable-length bitmap. This will be used in the next patch to allow the SUSPEND interrupt type to be disabled except when needed. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: sort all includes

2024-04-18T11:01:05+00:00

Establish the rule that header files are always included in sorted (POSIX local) order. Standard and private headers are separated by a blank line. Similarly, sort all forward-declarations for structures. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni

net: ipa: Remove unnecessary print function dev_err()

2024-04-17T00:15:20+00:00

The print function dev_err() is redundant because platform_get_irq_byname() already prints an error. ./drivers/net/ipa/ipa_interrupt.c:300:2-9: line 300 is redundant because platform_get_irq() already prints an error.

net: ipa: don't save the platform device

2024-03-04T11:44:41+00:00

The IPA platform device is now only used as the structure containing the IPA device structure. Replace the platform device pointer with a pointer to the device structure. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: introduce ipa_interrupt_init()

2024-03-04T11:44:40+00:00

Create a new function ipa_interrupt_init() that is called at probe time to allocate and initialize the IPA interrupt data structure. Create ipa_interrupt_exit() as its inverse. This follows the normal IPA driver pattern of *_init() functions doing things that can be done before access to hardware is required. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: change ipa_interrupt_config() prototype

2024-03-04T11:44:40+00:00

Change the return type of ipa_interrupt_config() to be an error code rather than an IPA interrupt structure pointer, and assign the the pointer within that function. Change ipa_interrupt_deconfig() to take the IPA pointer as argument and have it invalidate the ipa->interrupt pointer. Signed-off-by: Alex Elder Signed-off-by: David S. Miller

net: ipa: don't bother zeroing an already zero register

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

In ipa_interrupt_suspend_clear_all(), if the SUSPEND_INFO register read contains no set bits, there's no interrupt condition to clear. Skip the write to the clear register in that case. Signed-off-by: Alex Elder Signed-off-by: Paolo Abeni
