From: Rasmus Villemoes Date: Tue, 4 Jun 2019 07:34:23 +0000 (+0000) Subject: net: dsa: mv88e6xxx: add mv88e6250_g1_ieee_pri_map X-Git-Tag: v5.4-rc1~616^2~333^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=df63b0d95ec59f47df3a8beaeb75557c4bc49c00;p=platform%2Fkernel%2Flinux-rpi.git net: dsa: mv88e6xxx: add mv88e6250_g1_ieee_pri_map Quite a few of the existing supported chips that use mv88e6085_g1_ieee_pri_map as ->ieee_pri_map (including, incidentally, mv88e6085 itself) actually have a reset value of 0xfa50 in the G1_IEEE_PRI register. The data sheet for the mv88e6095, however, does describe a reset value of 0xfa41. So rather than changing the value in the existing callback, introduce a new variant with the 0xfa50 value. That will be used by the upcoming mv88e6250, and existing chips can be switched over one by one, preferably double-checking both the data sheet and actual hardware in each case - if anybody actually feels this is important enough to care.
