Serial function driver creates debugfs files even though ports
are not allocated. Fetching/reading those files without allocation
of ports leads to crash. Check port allocation before creating
the files.

Added channel state and checks to avoid glink channel opening twice
during timeout of previous call. Clean up and added more checks.

The ungate work turns on the clock before it exits hibern8,
if the link was put in hibern8 during clock gating work.
There occurs a race condition when clock scaling work calls
ufshcd_hold() to make sure low power states cannot be entered,
but that returns by checking only whether the clocks are on.
This causes the clock scaling work to issue UIC commands when
the link is in hibern8 causing failures. Make sure we exit
hibern8 state before returning from ufshcd_hold().

As the PD PHY probes, assign the static __pdphy pointer with
the pdphy instance prior to calling usbpd_create(). This ensures
that if the policy engine state machine kicks off right away
and calls back into the PHY APIs that there is a valid instance
found.
As further safeguarding, also fix the open/close/signal/write APIs
in the case where the instance cannot be found by using pr_err
instead of dev_err which would lead to a NULL pointer dereference.

Checking offset_entry is not necessary when using DDR addresses.
Check offset_entry only when using header tables.

While NOC timeout feature is enabled, L1 and L1 substate
low power mode should be disabled. Thus, disable L1 and L1ss
for PCIe on msmcobalt.

POWER_SUPPLY_STATUS shows 'Discharging' when DCIN is the only charging
input, because current input online report is solely based on USB.
