From fb9ed23c22d770a688092a082cfc459854749bd2 Mon Sep 17 00:00:00 2001 From: Tony Dinh Date: Sun, 30 Jan 2022 15:02:30 -0800 Subject: [PATCH] arm: kirkwood: Dreamplug : Use Marvell uclass mvgbe and PHY driver for Ethernet MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Globalscale Technologies Dreamplug board has the network chip Marvell 88E1116R. Use uclass mvgbe and the compatible driver M88E1310 driver to bring up Ethernet. - Currently, CONFIG_RESET_PHY_R symbol is used in arch/arm/mach-kirkwood/include/mach/config.h for all Kirkwood boards with mv8831116 PHY, with each board defines the function reset_phy(). Undefine it for this board. - Add board_eth_init() to use uclass mvgbe to bring up both network port 0 and 1. And remove ad-hoc code. - Enable CONFIG_PHY_MARVELL to properly configure the network. - Add myself as maintainer (this board seems to be orphaned, could not contact Jason Cooper using current email). - Miscellaneous changes: Move constants to .c file and remove header file board/Marvell/dreamplug/dreamplug.h, cleanup comments.
