Subject: Clock init issues on apq8098
Date: Thu, 29 Nov 2018 13:40:42 +0100 [thread overview]
Message-ID: <f4271471-b60a-f056-b453-1cfa593a0fc4@free.fr> (raw)
Hello,
kernel: v4.20-rc4
DTB: qcom/msm8998-mtp
defconfig: platform defconfig minus lots of stuff to make kernel smaller
When I boot v4.20-rc4 on my APQ8098-based board, the clk driver prints
the following warnings. (Because they are not powered up yet?)

Another (totally unrelated) warning is:
CPU features: SANITY CHECK: Unexpected variation in SYS_ID_AA64MMFR0_EL1. Boot CPU: 0x00000000001122, CPU4: 0x00000000101122
Is that bad, doctor?
Regards.
