This patch-set split the last version, and addressed the review comments from
last version on serial driver code.
Changes from v6:
- Setted SPRD_TIMEOUT with 256 rather than 2048
- Used u32 instead of uint32_t
- Removed inline of handle_lsr_errors which is a single call

This series adds initial support for the MediaTek MT6397 PMIC and the
necessary infrastructure to attach it on the MT8135 / MT8173 SoCs.
The infrastructure includes:
- pericfg / infracfg controller support
The pericfg / infracfg controllers contain miscellaneous registers for
reset
This adds the perisys, infracfg and pmic wrapper nodes to the

This patchset modifies the GIC driver to allow it, on supported
platforms, to route IPI interrupts to FIQ. It then uses this
feature to implement arch_trigger_all_cpu_backtrace for arm.
In order to neatly (and safely) bring in the changes for the arm
we also make the sched_clock implementation
It is currently possible for FIQ handlers to re-enter gic_raise_softirq()
and lock up.

lock(x); <-- Lockup
arch/arm/ uses IPIs to implement arch_irq_work_raise(),
Currently gic_raise_softirq() is locked using upon irq_controller_lock.
This lock is primarily used to make register read-modify-write sequences
atomic but gic_raise_softirq() uses it instead to ensure that the

Currently if arch_trigger_all_cpu_backtrace() is called with interrupts
disabled and on a platform the delivers IPI_CPU_BACKTRACE using regular
IRQ requests the system will wedge for ten seconds waiting for the
current CPU to react to a masked interrupt.
This patch resolves this issue by calling
Currently it is possible for an NMI (or FIQ on ARM) to come in and
read sched_clock() whilst update_sched_clock() has locked the seqcount
for writing. This results in the NMI handler locking up when it calls
raw_read_seqcount_begin().
This patch fixes that problem by providing banked clock data
Currently it is not possible to exploit FIQ for systems with a GIC, even if
the systems are otherwise capable of it. This patch makes it possible
for IPIs to be delivered using FIQ.
To do so it modifies the register state so that normal interrupts are
placed in group 1 and specific IPIs are
Currently there is a quite a pile of code sitting in
arch/x86/kernel/apic/hw_nmi.c to support safe all-cpu backtracing from NMI.
The code is inaccessible to backtrace implementations for other
architectures, which is a shame because they would probably like to be
safe too.
Copy this code into
Duplicate the x86 code to trigger a backtrace using an NMI and hook

IPI will be delivered at FIQ level.
Also provided are a few small items of plumbing to hook up the new code.
