- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks because
the clk provider device is repeatedly runtime PM resumed and
suspended during probe and clk registration. Resuming the clk
provider device deadlocks with an ABBA deadlock due to genpd_lock and
the clk prepare_lock. The fix is to keep the device runtime resumed
while registering clks.
- Another runtime PM related deadlock, this time with disabling unused
clks during late init. We get an ABBA deadlock where a device is
runtime PM resuming (or suspending) while the disabling of unused
clks is happening in parallel. That runtime PM action calls into the
clk framework and tries to grab the clk prepare_lock while the
disabling of unused clks holds the prepare_lock and is waiting for
that runtime PM action to complete. The fix is to runtime resume all
the clk provider devices before grabbing the clk prepare_lock during
disable unused.
- A build fix to provide an empty devm_clk_rate_exclusive_get()
function when CONFIG_COMMON_CLK=n

Pull clk fixes from Stephen Boyd:
"A couple clk driver fixes, a build fix, and a deadlock fix:
- Mediatek mt7988 has broken PCIe because the wrong parent is used
- Mediatek clk drivers may deadlock when registering their clks
because the clk provider device is repeatedly runtime PM resumed
and suspended during probe and clk registration.
Resuming the clk provider device deadlocks with an ABBA deadlock
due to genpd_lock and the clk prepare_lock. The fix is to keep the
device runtime resumed while registering clks.
- Another runtime PM related deadlock, this time with disabling
unused clks during late init.
