clock: implement CLOCKSOURCE_MASK in terms of GENMASK_ULL

2023-04-17T07:00:44+00:00

Clang doesn't like our implementation of CLOCKSOURCE_MASK:

  common/clock.c:33:10: warning: shift count >= width of type [-Wshift-count-overflow]
	.mask = CLOCKSOURCE_MASK(64),
                ^~~~~~~~~~~~~~~~~~~~
  include/clock.h:8:63: note: expanded from macro 'CLOCKSOURCE_MASK'
	 #define CLOCKSOURCE_MASK(bits) (uint64_t)((bits) < 64 ? ((1ULL<<(bits))-1) : -1)

So the bits < 64 check we have is apparently not enough to suppress the
warning when built with clang.

Let's do what the kernel does and use GENMASK_ULL instead to get rid of
the last remaining warning when building ARCH=sandbox targettools_defconfig
with clang version 16.0.1.

Not functional change intended.

Subject: [PATCH 1/1] ARM:lib32: add architected timer

2023-03-09T10:59:16+00:00

In preparation for the introduction of the LS1021A support,
add a specific timer support based on the LS1046A support so
that delays can be used in the PBL.

clock: Change cyc2ns return type to uint64_t

2021-03-26T08:02:55+00:00

Using an uint32_t to count nanosec will overflow every ~4sec, this means
that if get_time_ns is not called often enough the time keeping will be
wrong. By changing the return type to uint64_t doesn't fix the underlying
overflow issue but it will take more than 500 years to happen and I think
it's safe to assume this won't be an issue.
