Subject: [PATCH v3 1/1] nexus: Fix gpio-reserved-ranges 85-88
Date: Thu, 15 Apr 2021 19:39:57 +0200 [thread overview]
Message-ID: <20210415173957.28533-1-petr.vorel@gmail.com> (raw)
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")

Hi,
NOTE: as I wrote there is also problem with 86588296acbf ("fdt: Properly
handle "no-map" field in the memory region") from v5.12-rc1-dontuse, but
that's another story.
Kind regards,
Petr
