[PATCH 1/2] ARM: zynq: add Digilent Zynq PYNQ Board(s)

Florian Klink flokli at flokli.de
Sun Dec 27 21:34:07 CET 2020


This adds the dts and entry in CONFIG_OF_LIST for the Digilent Zynq PYNQ
Board(s).

They're Zynq 7000 - based boards, the Z1 is from Digilent, the Z2 from
TUL.

They have a slightly different audio system, and a different pin header,
but these aren't really accessible from the PS, only from the PL, so the
DTB is the same.
