From: Yang Guo <guoyang2@huawei.com> commit af246cc6d0ed11318223606128bb0b09866c4c08 upstream. 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 Fixes: 8b82c4f883a7 ("clocksource/drivers/arm_arch_timer: Move MMIO timer programming over to CVAL") Cc: stable@vger.kernel.org Cc: Daniel Lezcano <daniel.lezcano@linaro.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Marc Zyngier <maz@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Acked-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Yang Guo <guoyang2@huawei.com> Signed-off-by: Shaokun Zhang <zhangshaokun@hisilicon.com> Link: https://lore.kernel.org/r/20220927033221.49589-1-zhangshaokun@hisilicon.com Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> --- drivers/clocksource/arm_arch_timer.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
