Add PCIe support in DTS for Sophgo SG2042 SoC

[PATCH 0/4] Add PCIe support in DTS for Sophgo SG2042 SoC

Posted by Chen Wang 3 months, 2 weeks ago

From: Chen Wang <unicorn_wang@outlook.com>

This new patch set is a continuation of the previous patchset
"[PATCH v3 0/7] Add PCIe support to Sophgo SG2042 SoC" [1].

The drivers and bindings have already been merged into the kernel
mainline, and this patchset will focus on submitting the remaining
DTS changes into the mainline.

This patchset is based on v6.18-rc1 and the only changes since v3
is a fix to address the comments from Manivannan Sadhasivam to make
sure PCI address of the I/O port to start from 0.
