This separates the kref for ion handles into two components.
Userspace requests through the ioctl will hold at most one
reference to the internally used kref. All additional requests
will increment a separate counter, and the original reference is
only put once that counter hits 0. This protects the kernel from
a poorly behaving userspace.

Commit <be0960374> ("scsi: ufs: scale up the gear in 2 steps") introduced
a bug where we would not scale up the gear to HS-G3 if
UFS_DEVICE_QUIRK_HS_G1_TO_HS_G3_SWITCH quirk isn't enabled for UFS device.
Fix this by allowing HS-G3 scaling irrespective of quirk state.

This patch segregates different PD data onto separate buffers
and then onto its own data stream.

For some use cases, mdp clock source needs to be parked at a safe
frequency when it is disabled and force enabled in order to execute
a safe dynamic switch. Add support for the same by adding
non_local_children flag.

When SMMU stage1 is enabled, set IOVA base and end in geometry
attr to allow PCIe driver to map the GIC MSI address.

Minidump only collect parts of memory which are registered
to its table. So add lpm_debug buffer to Minidump table.

Add Minidump support for clients to get minimum required data
at the time of system crash. The Minidump table resides in SMEM,
BOOT(SBL) will iterate the table entries and dumps out (to USB/Flash)
the data in address location.
Any client can register to this table with static or known addresses,
as currently Minidump doesn't support dumping of dynamic data structures.
To simplify post processing, we create an ELF header, where each entry in
the minidump table is a section in elf header.
If Memory dump table enabled, Dump all data entries registered with MDT.
Enable Minidump:
echo mini > /sys/kernel/dload/dload_mode

For branch clocks having aggr_sibling_rates flag as set, get_rate()
always returns the parents rate despite the branch clocks prepare
status. Fix the same by adding a check for branch prepare status
and aggr_sibling_rates flag value.
