<1> Support SDIO 3.0, workaround for non-standard behaviour(AP6335) Temporarily.
<2> Support SD3.0, and SDXC card should use exfat filesystem.
<3> Non-emmc devices that turning fail would not bug kernel.
Hotplug and poweroff-able (wifi,SD,MMC) devices support re-insert and try it again.
<4> note:
(a) card & io aware devices, f_max = 2 * clock, e.g USH_SDR104 means
support max 208MHz clock in standard.
(b) setup_bus doesn't need update clk in svi flow
(c) card_busy: bascially should check CMD,DATA[0:3], however we use
toggle tags to match svi flow now.
(d) shorter wait busy and remove dump_stack in vsi flow.
Card should be busy until clk re-enable and svi complete.
All behaviour follow the protocol, enjoy it!

rk808: fix deadlock when shutown or reboot
When shutdown, rk808 driver shutdown first, so io_lock mutex is locked.
At same time, gpu change freq by runtime pm, will locked on rk808_reg_read.
Finally, gpu device shutdown, call pm_runtime_barrier. Deadlock happens.
Fix this bug by make rk808 shutdown later.

bdi: avoid oops on device removal
commit
5acda9d12dcf1ad0d9a5a2a7c646de3472fa7555 upstream.
After commit
839a8e8660b6 ("writeback: replace custom worker pool
implementation with unbound workqueue") when device is removed while we
are writing to it we crash in bdi_writeback_workfn() ->
set_worker_desc() because bdi->dev is NULL.
This can happen because even though bdi_unregister() cancels all pending
flushing work, nothing really prevents new ones from being queued from
balance_dirty_pages() or other places.
Fix the problem by clearing BDI_registered bit in bdi_unregister() and
checking it before scheduling of any flushing work.

backing_dev: fix hung task on sync
commit
6ca738d60c563d5c6cf6253ee4b8e76fa77b2b9e upstream.
bdi_wakeup_thread_delayed() used the mod_delayed_work() function to
schedule work to writeback dirty inodes. The problem with this is that
it can delay work that is scheduled for immediate execution, such as the
work from sync_inodes_sb(). This can happen since mod_delayed_work()
can now steal work from a work_queue. This fixes the problem by using
queue_delayed_work() instead. This is a regression caused by commit
839a8e8660b6 ("writeback: replace custom worker pool implementation with
unbound workqueue").
The reason that this causes a problem is that laptop-mode will change
the delay, dirty_writeback_centisecs, to 60000 (10 minutes) by default.
In the case that bdi_wakeup_thread_delayed() races with
sync_inodes_sb(), sync will be stopped for 10 minutes and trigger a hung
task. Even if dirty_writeback_centisecs is not long enough to cause a
hung task, we still don't want to delay sync for that long.
We fix the problem by using queue_delayed_work() when we want to
schedule writeback sometime in future. This function doesn't change the
timer if it is already armed.
For the same reason, we also change bdi_writeback_workfn() to
immediately queue the work again in the case that the work_list is not
empty. The same problem can happen if the sync work is run on the
rescue worker.
