From c7206e978920bb87dd08679a11990a5548b62f36 Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Thu, 21 Feb 2019 12:02:01 -0500 Subject: [PATCH] ARM: k2g-ice: Add pinmux support for rgmii interface This add pinmux configuration for rgmii interface so that network driver can be supported on K2G ICE boards. The pinmux configurations for this are generated using the pinmux tool at https://dev.ti.com/pinmux/app.html#/default As this required some BUFFER_CLASS definitions, same is re-used from the linux defnitions in include/dt-bindings/pinctrl/keystone.h Signed-off-by: Murali Karicheri Reviewed-by: Lokesh Vutla Acked-by: Joe Hershberger --- arch/arm/mach-keystone/include/mach/mux-k2g.h | 5 +++++ board/ti/ks2_evm/mux-k2g.h | 19 +++++++++++++++++++ 2 files changed, 24 insertions(+) diff --git a/arch/arm/mach-keystone/include/mach/mux-k2g.h b/arch/arm/mach-keystone/include/mach/mux-k2g.h index 809b72d5bf..67d47f8172 100644 --- a/arch/arm/mach-keystone/include/mach/mux-k2g.h +++ b/arch/arm/mach-keystone/include/mach/mux-k2g.h @@ -27,6 +27,11 @@ #define PIN_PTU (1 << 17) /* pull up */ #define PIN_PTD (0 << 17) /* pull down */ +#define BUFFER_CLASS_B (0 << 19) +#define BUFFER_CLASS_C (1 << 19) +#define BUFFER_CLASS_D (2 << 19) +#define BUFFER_CLASS_E (3 << 19) + #define MODE(m) ((m) & 0x7) #define MAX_PIN_N 260 diff --git a/board/ti/ks2_evm/mux-k2g.h b/board/ti/ks2_evm/mux-k2g.h index 706fb7e838..8c184a85ae 100644 --- a/board/ti/ks2_evm/mux-k2g.h +++ b/board/ti/ks2_evm/mux-k2g.h @@ -346,6 +346,25 @@ struct pin_cfg k2g_ice_evm_pin_cfg[] = { { 133, MODE(0) }, /* SOC_QSPI_D2 */ { 134, MODE(0) }, /* SOC_QSPI_D3 */ { 135, MODE(0) }, /* SOC_QSPI_CSN0 */ + + /* EMAC */ + { 79, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXD1 */ + { 78, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXD2 */ + { 77, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXD3 */ + { 80, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXD0 */ + { 94, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXD0 */ + { 93, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXD1 */ + { 92, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXD2 */ + { 91, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXD3 */ + { 85, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXC */ + { 95, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_TXCTL */ + { 72, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXC */ + { 81, BUFFER_CLASS_D | PIN_PDIS | MODE(1) }, /* RGMII_RXCTL */ + + /* MDIO */ + { 99, BUFFER_CLASS_B | PIN_PDIS | MODE(0) }, /* MDIO_CLK */ + { 98, BUFFER_CLASS_B | PIN_PDIS | MODE(0) }, /* MDIO_DATA */ + { MAX_PIN_N, } }; -- 2.39.5
