Commit ff71266aa490 ("mfd: Drop obsolete JZ4740 driver") removed the last
file to include <linux/jz4740-adc.h> but left the header file itself
behind. Nothing uses it, remove it now.
Similarly, aea12071d6fc ("power/supply: Drop obsolete JZ4740 driver")
deleted the last use of <linux/power/jz4740-battery.h>, so remove that one
too.

It appears as though there are still references to both of these
*devices* in the kernel tree. Should those be removed also?

Patch looks fine though.
Let me know if you want me to take it in via MFD. Otherwise:

These files were for older drivers that were since then replaced by
newer drivers; JZ47xx SoCs are still officially supported and
maintained.

You can take it through MFD, no immutable branch needed.

Since the merge-window is already open, we'll aim for v5.17.

Are you sending this directly to Linus or do you want me to take it
through the NFS client tree? I'm fine either way.

Go ahead and take it, please, if that works; it's a bit off-topic for my
docs tree.

-/**
- * cnt32_to_63 - Expand a 32-bit counter to a 63-bit counter
- * @cnt_lo: The low part of the counter
- *
- * Many hardware clock counters are only 32 bits wide and therefore have
- * a relatively short period making wrap-arounds rather frequent. This
- * is a problem when implementing sched_clock() for example, where a 64-bit
- * non-wrapping monotonic value is expected to be returned.
- *
- * To overcome that limitation, let's extend a 32-bit counter to 63 bits
- * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
- * by the hardware while bits 32 to 62 are stored in memory. The top bit in
- * memory is used to synchronize with the hardware clock half-period. When
- * the top bit of both counters (hardware and in memory) differ then the
- * memory is updated with a new value, incrementing it when the hardware
- * counter wraps around.
- *
- * Because a word store in memory is atomic then the incremented value will
- * always be in synch with the top bit indicating to any potential concurrent
- * reader if the value in memory is up to date or not with regards to the
- * needed increment. And any race in updating the value in memory is harmless
- * as the same value would simply be stored more than once.
- *
- * The restrictions for the algorithm to work properly are:
- *
- * 1) this code must be called at least once per each half period of the
- * 32-bit counter;
- *
- * 2) this code must not be preempted for a duration longer than the
- * 32-bit counter half period minus the longest period between two
- * calls to this code;
- *
- * Those requirements ensure proper update to the state bit in memory.
- * This is usually not a problem in practice, but if it is then a kernel
- * timer should be scheduled to manage for this code to be executed often
- * enough.
- *
- * And finally:
- *
- * 3) the cnt_lo argument must be seen as a globally incrementing value,
- * meaning that it should be a direct reference to the counter data which
- * can be evaluated according to a specific ordering within the macro,
- * and not the result of a previous evaluation stored in a variable.
- *
- * For example, this is wrong:
- *
- * u32 partial = get_hw_count();
- * u64 full = cnt32_to_63(partial);
- * return full;
- *
- * This is fine:
- *
- * u64 full = cnt32_to_63(get_hw_count());
- * return full;
- *
- * Note that the top bit (bit 63) in the returned value should be considered
- * as garbage. It is not cleared here because callers are likely to use a
- * multiplier on the returned value which can get rid of the top bit
- * implicitly by making the multiplier even, therefore saving on a runtime
- * clear-bit instruction. Otherwise caller must remember to clear the top
- * bit explicitly.

Thanks!
[8/9] spi: remove unused header file <linux/platform_data/spi-clps711x.h>
commit: 45971bdd8ca8b5a99a49f4db86737401c45e246f
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
