I found some more definitions in lk2nd

88:#define  GCC_CRYPTO_BCR                    (CLK_CTL_BASE + 0x16000)
106:#define SDCC1_BCR                          (CLK_CTL_BASE + 0x42000) /* block reset*/

190:#define USB3PHY_PHY_BCR                 (CLK_CTL_BASE + 0x3F03C)

Couldn't find this one though, did you confirm that MDSS goes off
when you assert it?

That one's defined here:
https://gerrit-public.fairphone.software/plugins/gitiles/kernel/msm-4.9/+/refs/heads/int/13/fp3/arch/arm64/boot/dts/qcom/msm8953-mdss-pll.dtsi#21

I'll add some of the others in v2.
