mainline inclusion from mainline-v6.1-rc1 commit af246cc6d0ed11318223606128bb0b09866c4c08 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6RQVI
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
CNTPCT_LO and CNTVCT_LO are defined by mistake in commit '8b82c4f883a7', so fix them according to the Arm ARM DDI 0487I.a, Table I2-4 "CNTBaseN memory map" as follows:
Offset Register Type Description 0x000 CNTPCT[31:0] RO Physical Count register. 0x004 CNTPCT[63:32] RO 0x008 CNTVCT[31:0] RO Virtual Count register. 0x00C CNTVCT[63:32] RO
