In the past we only need on clock which name "pclk" for a gpio controller.
In the new version gpio controller, there add some register to change
debounce clock dynamic, so the dt node needs to add the second clock, we
call it "dbclk".
The clock property need 2 items on some rockchip chips such as RK3568
SoCs.

- Add support for partitionned EPPIs, modeled after the existing
partitioned PPI support
* irq/gicv3-eppi-partition:
irqchip/gic-v3: Fix selection of partition domain for EPPIs
irqchip/gic-v3: Add __gic_get_ppi_index() to find the PPI number from hwirq
Signed-off-by: Marc Zyngier <maz@kernel.org>
commit 5f51f80382 ("irqchip/gic-v3: Add EPPI range support") added
GIC_IRQ_TYPE_PARTITION support for EPPI to gic_irq_domain_translate(),
and commit 52085d3f20 ("irqchip/gic-v3: Dynamically allocate PPI
partition descriptors") made the gic_data.ppi_descs array big enough for
EPPI, but neither gic_irq_domain_select() nor partition_domain_translate()
were updated.
This means partitions are created by partition_create_desc() for the
EPPI range, but can't be registered as they will always match the root
domain and map to the summary interrupt.
Update gic_irq_domain_select() to match PPI and EPPI. The fwspec for
PPI and EPPI both start from 0. Use gic_irq_domain_translate() to find
the hwirq from the fwspec, then convert this to a ppi index.

gic_get_ppi_index() is a useful concept for ppi partitions, as the GIC
has two PPI ranges but needs mapping to a single range when used as an
index in the gic_data.ppi_descs[] array.
Add a double-underscore version which takes just the intid. This will
be used in the partition domain select and translate helpers to enable
partition support for the EPPI range.

gcc doesn't care, but clang quite reasonably pointed out that the recent
commit e9ba16e68c ("smpboot: Mark idle_init() as __always_inlined to
work around aggressive compiler un-inlining") did some really odd
things:
kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier]
static inline void __always_inline idle_init(unsigned int cpu)
^
which not only has that duplicate inlining specifier, but the new
__always_inline was put in the wrong place of the function definition.
We put the storage class specifiers (ie things like "static" and
"extern") first, and the type information after that. And while the
compiler may not care, we put the inline specifier before the types.
So it should be just
static __always_inline void idle_init(unsigned int cpu)
instead.
