From: Vivien Didelot Date: Mon, 12 Jun 2017 16:37:36 +0000 (-0400) Subject: net: dsa: mv88e6xxx: prefix Port Switch ID macros X-Git-Tag: v4.14-rc1~596^2~211^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=107fcc10e810be24631bf54d35970071b110ad10;p=platform%2Fkernel%2Flinux-rpi3.git net: dsa: mv88e6xxx: prefix Port Switch ID macros For implicit namespacing and clarity, prefix the common Switch ID Register macros with MV88E6XXX_PORT_SWITCH_ID. Document the register and prefer ordered hex masks values for all Marvell 16-bit registers, this means shifting their values by 4. Signed-off-by: Vivien Didelot Signed-off-by: David S.
