Subject: [PATCH 2/2] Revert "arm64: dts: ls1028a: add flextimer based pwm nodes"
Date:   Sat, 15 Jan 2022 22:09:07 +0100

The changes to the device tree look very wrong. There are now two
devices with the same base address: pwm0 and ftm_alarm0. Both are using
the Flex Timer Module. It seems like this should either be one driver or
and MFD driver. Either way, there should only be one node in the device
tree. Revert the offending changes to avoid getting a broken device tree
in circulation.

This reverts commit 71799672ea24d2935322d655d2407c1ccd7db9ff.

Fixes: 71799672ea24 ("arm64: dts: ls1028a: add flextimer based pwm nodes")

Btw, the nodes are also not sorted by the address. Otherwise it should have
been spotted easily.
