[ Upstream commit f890f89d9a80fffbfa7ca791b78927e5b8aba869 ]
Reserve GPIO pins 85-88 as these aren't meant to be accessible from the application CPUs (causes reboot). Yet another fix similar to 9134586715e3, 5f8d3ab136d0, which is needed to allow angler to boot after 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning").
Fixes: feeaf56ac78d ("arm64: dts: msm8994 SoC and Huawei Angler (Nexus 6P) support")

Yes, this patch needs modification, because tlmm was added in v5.9 in 7c865b09b0a1 ("arm64: dts: qcom: msm8994: Modernize the DTS style"). Before it was msmgpio, thus substitute to it should fix it. I can verify it and send correct patches, but this problem started since 3edfb7bd76bd (v4.20), thus I'd prefer just skip linux-4.19.y and linux-4.14.y (unless 3edfb7bd76bd is planning to be backported to it, which I don't think so).
Kind regards, Petr
