The PDMIC needs PDM microphones to work. sama5d2 xplained doesn't have
such microphones, so there is no reason to enable PDMIC and take some
pins since there is no-one using them. Isn't it the policy to enable
only what is present on a board?

Hi,
The correct subject line prefix is "ARM: dts: at91:"

This patch doesn't apply and I think you'll have to motivate the removal
a bit more because this seems like a change of policy to me.

[PATCH 3/3] Revert "ARM: at91/dt: sama5d2 Xplained: add pdmic node"
There are no PDM microphones on SAMA5D2 Xplained, to exercize the
PDMIC.
This reverts commit ca6349a8c51f2e3d6f2acdb36431e7d7328261f7.
