Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
drivers/bus/Kconfig between commit c9966c98697a ("arm-cci: Split the
code for PMU vs driver support") from the arm-perf tree and commit
13fbf3c8d0f7 ("drivers: bus: Sort Kconfig entries alphabetically") from
the arm-soc tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
Not sure if this has been reported elsewhere, but I am seeing core
boot-up failures on the exynos5420 with next-20150323 due to this.
Your conflict fix is missing the ARM_CCI symbol because of which the
CCI does not get enabled.
Suzuki, can you confirm ?
Yes, you are right. We need the config ARM_CCI even now, which enables
the building of the arm-cci.c.
Stephen,
We need the following fix on the linux-next.
