[PATCH v4 00/10] New PolarFire SoC devkit devicetrees & 22.09 reference design updates

From: Conor Dooley
Date: Thu Sep 08 2022 - 07:18:03 EST


Hey all,

Some 6.1 targeted changes here.
Firstly, two new dev kits (one first-party & one from Aries Embedded).
They've been sitting in our vendor tree, so are being sent where they
belong.

Secondly, another release of our reference design for the Icicle kit
is due in September. Usually these do not really change much for the
devicetree, but this time around a pair of changes impact the memory
map.

The first of these is adding dma-ranges to the pcie controller. The
controller had some issues to begin with & with the current reference
design (v2022.05) would not work with mainline Linux nor has it since
reference design v2021.08. A combination of the property, a change
to the FPGA design & a small fix to the driver will get it working
with mainline again. The other non-backwards compatible change to the
reference design is moves of the peripherals instantiated in the
fabric. Currently they are fairly spread out & a common complaint has
been that this leaves little room in the fic3 section of the memory map
for custom peripherals without removing the existing ones.

This series depends on [0] so as not to add dtbs_check warnings. The
fabric clock support is added by [1].

Thanks,
Conor.

Changes since v3:
- add an extra patch reducing the fic3 clock rate

Changes since v2:
- drop the sd & emmc versions of the aries devicetree
- remove a extra newline

Changes since v1:
- made the polarberry part of an enum in patch 1
