| Subject | [PATCH for v4.9 LTS 61/87] sh_eth: fix EESIPR values for SH77{34|63} |
| Message-ID | <u3k4b-3a5-27@gated-at.bofh.it> |
From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
[ Upstream commit 978d3639fd13d987950e4ce85c8737ae92154b2c ]
As the SH77{34|63} manuals are freely available, I've checked the EESIPR
values written against the manuals, and they appeared to set the reserved
bits 11-15 (which should be 0 on write). Fix those EESIPR values.
Fixes: 380af9e390ec ("net: sh_eth: CPU dependency code collect to "struct sh_eth_cpu_data"")
Fixes: f5d12767c8fd ("sh_eth: get SH77{34|63} support out of #ifdef")
