Remove local connect limits and connect_attempts variable. Use fabrics new nr_connects variable and use of nvmf_should_reconnect() Refactor duplicate reconnect failure code.

Then blk_mq_abort_requeue_list() is called in both nvme_kill_queues() and nvme_ns_remove() for dealing with this issue. Unfortunately blk_mq_abort_requeue_list() is absolutely a race maker, for example, one request may be requeued during the aborting. So this patch just calls blk_mq_kick_requeue_list() in nvme_kill_queues() to handle this issue like what nvme_start_queues() does. Now all requests in requeue list when queues are stopped will be handled by blk_mq_kick_requeue_list() when queues are restarted, either in nvme_start_queues() or in nvme_kill_queues().

Given nvme_kill_queues() is run from either remove context or reset worker context, both are fine to run hw queue directly. And the mutex of namespaces_mutex isn't a problem too becasue nvme_start_freeze() runs hw queue in this way already.

With this stragety, default setting of latency/idle isn't important, so just set them to very conservative and safe value.

Add a flag that when set resumes the device before calling the driver's system suspend handlers which effectively disables the optimization. Needed by a future patch fixing suspend/resume on i915.

Synchronous aborts need to be handled differently from the async aborts we were getting before, in particular the PC needs to be advanced when resolving the abort. This is mostly a copy of what other PCI drivers do on ARM to handle those aborts.

However, in corner case configurations where the partition ID is not zero and NTB is not enabled, the code will have the wrong partition ID and this causes the driver to use the wrong set of drivers. To fix this we simply take the partition ID from the system info region.

Currently the SDIO card can't be detected and thus the Wifi doesn't work. Let's fix this by assigning the correct vmmc supply, which is the always on regulator VDD_3V3 and remove the WLAN enable regulator altogether. Then to properly deal with the power on/off sequence, add a mmc-pwrseq node to describe the resources needed to detect the SDIO card. Except for the WLAN enable GPIO and its corresponding assert/de-assert delays, the mmc-pwrseq node also contains a handle to a clock provided by the hi655x pmic. This clock is also needed to be able to turn on the WiFi chip. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Arnd Bergmann <arnd@arndb.de>

While changing this, let's take the opportunity to drop the use of the "ti,non-removable" binding for one of the dwmmc device nodes, as it's not a valid binding and not used. Drop also the unnecessary use of "num-slots = <0x1>" for all of the dwmmc nodes, as there is no need to set this since when default number of slots is one.

This code is really bad. But for now, let's just fix this. I will hopefully have a large patch series to refactor all of this soon.
