Subject: [PATCH 1/2] ARM: zynq: add Digilent Zynq PYNQ Board(s)
Date: Sun, 27 Dec 2020 21:34:07 +0100	[thread overview]
Message-ID: <20201227203408.3882-1-flokli@flokli.de> (raw)

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.
