Subject: [PATCH 0/2] sunxi: Fix Ethernet on mostly A20 boards
Date: Wed, 16 Mar 2022 00:54:41 +0000 [thread overview]
Message-ID: <20220316005443.16260-1-andre.przywara@arm.com> (raw)
Hi,
testing on a BananaPi M1 board revealed that Ethernet has regressed
since the last release due to not only one, but two bugs:
- The pinmux and GMAC clock setup for the A20 GMAC is apparently called
too early now.
- The updated RGMII phy-mode properties are now taken for real, so many
boards are using the wrong RX/TX line delay setup, with mostly fatal
consequences.
Fix those two issues to bring Ethernet back on those affected boards.
I refrained from just syncing the DTs from the kernel (to fix the second
issue): Recent changes in the mainline DTs require newer kernels to work,
which breaks Linux distro installer ISO images running via UEFI.
We need to find a solution for that, but not in -rc4, which
would be rather late for a normal DT sync anyway.
Please have a look and test on your board!
Cheers,
Andre
