At this point the PFC driver lacks DT bindings so to configure the PFC we use PINCTRL in C board code. Signed-off-by: Magnus Damm <damm@opensource.se> --- Changes since V2: - Put SMSC chip in case of DT inside 32-bit lbsc Changes since V1: - Use PINCTRL instead of function GPIOs. - Modify bootargs to enable DHCP and NFS root. arch/arm/boot/dts/r8a73a4-ape6evm.dts | 23 ++++++++++++++++++- arch/arm/mach-shmobile/board-ape6evm.c | 38 ++++++++++++++++++++++++++++++++ 2 files changed, 60 insertions(+), 1 deletion(-) --- 0003/arch/arm/boot/dts/r8a73a4-ape6evm.dts +++ work/arch/arm/boot/dts/r8a73a4-ape6evm.dts 2013-03-29 16:20:40.000000000 +0900 @@ -16,7 +16,7 @@ compatible = "renesas,ape6evm", "renesas,r8a73a4"; chosen { - bootargs = "console=ttySC0,115200 ignore_loglevel"; + bootargs = "console=ttySC0,115200 ignore_loglevel root=/dev/nfs ip=dhcp"; }; memory@40000000 { @@ -24,8 +24,29 @@ reg = <0 0x40000000 0 0x40000000>; }; + ape6evm_fixed_3v3: fixedregulator@0 { + compatible = "regulator-fixed"; + regulator-name = "3V3"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; + lbsc { #address-cells = <1>; #size-cells = <1>; + + ethernet@8000000 { + compatible = "smsc,lan9118", "smsc,lan9115"; + reg = <0x08000000 0x1000>; + interrupt-parent = <&irqc1>; + interrupts = <8 0x4>; + phy-mode = "mii"; + reg-io-width = <4>; + smsc,irq-active-high; + smsc,irq-push-pull; + vdd33a-supply = <&ape6evm_fixed_3v3>; + vddvario-supply = <&ape6evm_fixed_3v3>; + }; }; }; --- 0004/arch/arm/mach-shmobile/board-ape6evm.c +++ work/arch/arm/mach-shmobile/board-ape6evm.c 2013-03-29 16:19:49.000000000 +0900 @@ -18,20 +18,49 @@ * Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA */ +#include <linux/gpio.h> #include <linux/interrupt.h> #include <linux/irqchip.h> #include <linux/kernel.h> #include <linux/pinctrl/machine.h> #include <linux/platform_device.h> +#include <linux/regulator/fixed.h> +#include <linux/regulator/machine.h> +#include <linux/smsc911x.h> #include <mach/common.h> +#include <mach/irqs.h> #include <mach/r8a73a4.h> #include <asm/mach-types.h> #include <asm/mach/arch.h> +/* Dummy supplies, where voltage doesn't matter */ +static struct regulator_consumer_supply dummy_supplies[] = { + REGULATOR_SUPPLY("vddvario", "smsc911x"), + REGULATOR_SUPPLY("vdd33a", "smsc911x"), +}; + +/* SMSC LAN9220 */ +static const struct resource lan9220_res[] = { + DEFINE_RES_MEM(0x08000000, 0x1000), + { + .start = irq_pin(40), /* IRQ40 */ + .flags = IORESOURCE_IRQ | IRQF_TRIGGER_HIGH, + }, +}; + +static const struct smsc911x_platform_config lan9220_data = { + .flags = SMSC911X_USE_32BIT, + .irq_type = SMSC911X_IRQ_TYPE_PUSH_PULL, + .irq_polarity = SMSC911X_IRQ_POLARITY_ACTIVE_HIGH, +}; + static const struct pinctrl_map ape6evm_pinctrl_map[] = { /* SCIFA0 console */ PIN_MAP_MUX_GROUP_DEFAULT("sh-sci.0", "pfc-r8a73a4", "scifa0_data", "scifa0"), + /* SMSC */ + PIN_MAP_MUX_GROUP_DEFAULT("smsc911x", "pfc-r8a73a4", + "irqc_irq40", "irqc"), }; static void __init ape6evm_add_standard_devices(void) @@ -41,6 +70,15 @@ static void __init ape6evm_add_standard_ ARRAY_SIZE(ape6evm_pinctrl_map)); r8a73a4_pinmux_init(); r8a73a4_add_standard_devices(); + + /* LAN9220 ethernet */ + gpio_request_one(270, GPIOF_OUT_INIT_HIGH, NULL); /* smsc9220 RESET */ + + regulator_register_fixed(0, dummy_supplies, ARRAY_SIZE(dummy_supplies)); + + platform_device_register_resndata(&platform_bus, "smsc911x", -1, + lan9220_res, ARRAY_SIZE(lan9220_res), + &lan9220_data, sizeof(lan9220_data)); } static const char *ape6evm_boards_compat_dt[] __initdata = {
