Subject: [PATCH net] net: bgmac: fix BCM5358 support by setting correct flags
Date: Wed, 8 Feb 2023 10:16:37 +0100 [thread overview]
Message-ID: <20230208091637.16291-1-zajec5@gmail.com> (raw)
From: Rafał Miłecki <rafal@milecki.pl>
Code blocks handling BCMA_CHIP_ID_BCM5357 and BCMA_CHIP_ID_BCM53572 were
incorrectly unified. Chip package values are not unique and cannot be
checked independently. They are meaningful only in a context of a given
chip.
Packages BCM5358 and BCM47188 share the same value but then belong to
different chips. Code unification resulted in treating BCM5358 as
BCM47188 and broke its initialization.

Fixes: cb1b0f90acfe ("net: ethernet: bgmac: unify code of the same family")
