Subject: [PATCH net 1/3] sh_eth: fix TRSCER mask for SH771x
Date: Sun, 28 Feb 2021 23:25:43 +0300 [thread overview]
Message-ID: <a92afef3-2ae8-e8c7-855d-f0e86a1beede@omprussia.ru> (raw)
In-Reply-To: <7009ba70-4134-1acf-42b9-fa7e59b5d15d@omprussia.ru>
According to the SH7710, SH7712, SH7713 Group User's Manual: Hardware,
Rev. 3.00, the TRSCER register actually has only bit 7 valid (and named
differently), with all the other bits reserved. Apparently, this was not
the case with some early revisions of the manual as we have the other
bits declared (and set) in the original driver. Follow the suit and add
the explicit sh_eth_cpu_data::trscer_err_mask initializer for SH771x...
Fixes: 86a74ff21a7a ("net: sh_eth: add support for Renesas SuperH Ethernet")
