From 485bba395e00a3a9a250ae1d02abb9cff314e8e7 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Wed, 5 Sep 2018 15:56:12 +0200 Subject: ARM: meson: Add support for AXG family This patch adds support for the Amlogic AXG SoC, which is very close from the Amlogic GXL SoCs with : - Same 4xCortex-A53 CPUs but clocked at 1.2GHZ max - DDR Interface limited to DDR4 16bit - The whole physical register address space has been moved to 0xfxxxxxxx - The pinctrl setup has changed - The clock tree is different enough to use a different driver Signed-off-by: Jerome Brunet Signed-off-by: Neil Armstrong --- arch/arm/include/asm/arch-meson/axg.h | 51 +++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 arch/arm/include/asm/arch-meson/axg.h (limited to 'arch/arm/include') diff --git a/arch/arm/include/asm/arch-meson/axg.h b/arch/arm/include/asm/arch-meson/axg.h new file mode 100644 index 00000000000..28a38b791d1 --- /dev/null +++ b/arch/arm/include/asm/arch-meson/axg.h @@ -0,0 +1,51 @@ +/* SPDX-License-Identifier: GPL-2.0+ */ +/* + * Copyright (C) 2018 BayLibre, SAS + * Author: Neil Armstrong + */ + +#ifndef __AXG_H__ +#define __AXG_H__ + +#define AXG_AOBUS_BASE 0xff800000 +#define AXG_PERIPHS_BASE 0xff634400 +#define AXG_HIU_BASE 0xff63c000 +#define AXG_ETH_BASE 0xff3f0000 + +/* Always-On Peripherals registers */ +#define AXG_AO_ADDR(off) (AXG_AOBUS_BASE + ((off) << 2)) + +#define AXG_AO_SEC_GP_CFG0 AXG_AO_ADDR(0x90) +#define AXG_AO_SEC_GP_CFG3 AXG_AO_ADDR(0x93) +#define AXG_AO_SEC_GP_CFG4 AXG_AO_ADDR(0x94) +#define AXG_AO_SEC_GP_CFG5 AXG_AO_ADDR(0x95) + +#define AXG_AO_MEM_SIZE_MASK 0xFFFF0000 +#define AXG_AO_MEM_SIZE_SHIFT 16 +#define AXG_AO_BL31_RSVMEM_SIZE_MASK 0xFFFF0000 +#define AXG_AO_BL31_RSVMEM_SIZE_SHIFT 16 +#define AXG_AO_BL32_RSVMEM_SIZE_MASK 0xFFFF + +/* Peripherals registers */ +#define AXG_PERIPHS_ADDR(off) (AXG_PERIPHS_BASE + ((off) << 2)) + +#define AXG_ETH_REG_0 AXG_PERIPHS_ADDR(0x50) +#define AXG_ETH_REG_1 AXG_PERIPHS_ADDR(0x51) + +#define AXG_ETH_REG_0_PHY_INTF_RGMII BIT(0) +#define AXG_ETH_REG_0_PHY_INTF_RMII BIT(2) +#define AXG_ETH_REG_0_TX_PHASE(x) (((x) & 3) << 5) +#define AXG_ETH_REG_0_TX_RATIO(x) (((x) & 7) << 7) +#define AXG_ETH_REG_0_PHY_CLK_EN BIT(10) +#define AXG_ETH_REG_0_INVERT_RMII_CLK BIT(11) +#define AXG_ETH_REG_0_CLK_EN BIT(12) + +/* HIU registers */ +#define AXG_HIU_ADDR(off) (AXG_HIU_BASE + ((off) << 2)) + +#define AXG_MEM_PD_REG_0 AXG_HIU_ADDR(0x40) + +/* Ethernet memory power domain */ +#define AXG_MEM_PD_REG_0_ETH_MASK (BIT(2) | BIT(3)) + +#endif /* __AXG_H__ */ -- cgit v1.2.3
