From a2d705318866ed1322fceb4971bfc6a62d695353 Mon Sep 17 00:00:00 2001 From: Emmanuel Vadot Date: Wed, 20 Jun 2018 15:27:09 +0000 Subject: [PATCH] if_rk_dwc: Disable setting delays for now The values for tx/rx delays differs accross the different DTS. Mainline Linux set it to 0x24/0x18 Mostly-Vendor u-boot (the one maintained and developped) to 0x18/0x18 Mostly-Vendor linux (the one maintained and developped) to 0x26/0x11 By experience only 0x18/0x18 works so until the issue is resolved rely on the bootloader settings. --- sys/arm64/rockchip/if_dwc_rk.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/sys/arm64/rockchip/if_dwc_rk.c b/sys/arm64/rockchip/if_dwc_rk.c index 54cda16f0b30..f0b54f841211 100644 --- a/sys/arm64/rockchip/if_dwc_rk.c +++ b/sys/arm64/rockchip/if_dwc_rk.c @@ -80,7 +80,8 @@ rk3328_set_delays(struct syscon *grf, phandle_t node) rx = ((rx & RK3328_GRF_MAC_CON0_TX_MASK) << RK3328_GRF_MAC_CON0_RX_SHIFT); - SYSCON_WRITE_4(grf, RK3328_GRF_MAC_CON0, tx | rx | 0xFFFF0000); + /* Disable delays as values conflict between DTS */ + /* SYSCON_WRITE_4(grf, RK3328_GRF_MAC_CON0, tx | rx | 0xFFFF0000); */ } static int
