Since both VSC9959 and VSC9953 are embedded switches (one on an arm64 SoC and the other on a powerpc SoC), there is no use case for having the code for both be present in the same module. This was necessary at the time due to the common SERDES PCS code that they were using, but that has been since refactored into drivers/net/pcs/pcs-lynx.c. This makes the Seville driver stop uselessly depending upon PCI and FSL_ENETC_MDIO, which were only dependencies of Felix in fact. Some whitespace/tab conversions are also present in this series as part of the cleanup process. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Version 2 replaced the first patch from version 1 with three patches, in response to David Miller's feedback. And based on Bjorn Andersson's feedback on version 2, this version reworks the tracking of IPA clock references. As a result, we no longer need a flag to determine whether a "don't' suspend" clock reference is held (though an bit in a bitmask is still used for a different purpose). In summary: - A refcount_t is used to track IPA clock references where an atomic_t was previously used. (This may go away soon as well, with upcoming work to implement runtime PM.) - We no longer track whether a special reference has been taken to avoid suspending IPA. - A bit in a bitmask is used to ensure we only trigger a system resume once per system suspend. And from the original series: - Suspending endpoints only occurs when suspending the driver, not when dropping the last clock reference. Resuming endpoints is also disconnected from starting the clock. - The IPA SUSPEND interrupt is now a wakeup interrupt. If it fires, it schedules a system resume operation. - The GSI interrupt is no longer a wakeup interrupt. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The CLOCK_HELD flag was previously used to indicate that an extra clock reference was held, preventing suspend. But we no longer need such a flag: - We take an initial reference in ipa_config(). - That reference is held until ipa_suspend() releases it. - A subsequent system resume leads to a reference getting re-acquired in ipa_resume(). - This can repeat until ultimately the module is removed, where ipa_remove() releases the reference. We no longer need a special flag to determine whether this extra reference is held--it is, provided probe has completed successfully and the driver is not suspended (or removed). On the other hand, once suspended, it's possible for more than one endpoint to trip the IPA SUSPEND interrupt, and we only want to trigger the system resume once. So repurpose the Boolean CLOCK_HELD flag to record whether the IPA SUSPEND handler should initiate a system resume. The flag will be be cleared each time ipa_suspend() is called, *before* any endpoints are suspended. And it will be set inside the IPA SUSPEND interrupt handler exactly once per suspend. Rename the flag IPA_FLAG_RESUMED to reflect its new purpose. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The call to wakeup_source_register() in ipa_probe() does not do what it was intended to do. Call device_init_wakeup() in ipa_setup() instead, to set the IPA device as wakeup-capable and to initially enable wakeup capability. When we receive a SUSPEND interrupt, call pm_wakeup_dev_event() with a zero processing time, to simply call for a resume without any other processing. The ipa_resume() call will take care of waking things up again, and will handle receiving the packet. Note that this gets rid of a clock reference counting bug that occurred when handling an IPA SUSPEND interrupt. Specifically, ipa_suspend_handler() took an IPA clock reference *in addition* to the one taken by ipa_resume(). There is no need to back-port this fix however, because it only affects code that was not previously working (this patch is part of fixing that).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when (before) the last IPA clock reference is dropped, all endpoints are suspended. And whenever the first IPA clock reference is taken, all endpoints are resumed (or started). In most cases there's no need to start endpoints when the clock starts. So move the calls to ipa_endpoint_suspend() and ipa_endpoint_resume() out of ipa_clock_put() and ipa_clock_get(), respectiely. Instead, only suspend endpoints when handling a system suspend, and only resume endpoints when handling a system resume.
