From 368b6d1a52e57e9cce3b92fcef6928bee995617b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Tue, 20 Nov 2018 00:16:27 +0100 Subject: [PATCH] ath79: gmac: ar934x: Add parser for mii-gmac0-slave MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit While converting Nanostation M XW from current ar71xx code to ath79 I've hit one issue, where the ethernet networking wasn't working, so I was checking every bit in the networking setup path between ar71xx and ath79. I've came to the following code in ar71xx/mach-ubnt-xm.c: static void __init ubnt_xw_init(void) { ... ath79_setup_ar934x_eth_cfg(AR934X_ETH_CFG_MII_GMAC0 | AR934X_ETH_CFG_MII_GMAC0_SLAVE); ... } Where this code is setting AR934X_ETH_CFG_MII_GMAC0_SLAVE bit in AR934X_GMAC_REG_ETH_CFG register, but I couldn't find a way of setting this bit from DTS, so this patch adds `mii-gmac0-slave` DTS property which allows setting of this bit in `gmac-config`, which is then used in Nanostation M XW DTS.
