The u-boot env isn't setup properly + either and as a result, the bcm47xxpart probing is not + working. Hence, the nand partitions are specified through a + "fixed-partition" binding. + - The "WICED SMART(TM)" Bluetooth LE 4.0 BCM20732 chip is + connected to uart2 of the SoC. The BCM20732 does not + provide a HCI. So the linux' bluetooth stack is useless. + The mock-up node with the compatible binding and + enable-gpios property is provided solely as documentation. + +Signed-off-by: Christian Lamparter <chunkeey@gmail.com> +Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> + +--- a/arch/arm/boot/dts/Makefile ++++ b/arch/arm/boot/dts/Makefile +@@ -119,6 +119,7 @@ dtb-$(CONFIG_ARCH_BCM_5301X) += \ + bcm47094-luxul-xwr-3150-v1.dtb \ + bcm47094-netgear-r8500.dtb \ + bcm47094-phicomm-k3.dtb \ ++ bcm53016-meraki-mr32.dtb \ + bcm94708.dtb \ + bcm94709.dtb \ + bcm953012er.dtb \ +--- /dev/null ++++ b/arch/arm/boot/dts/bcm53016-meraki-mr32.dts +@@ -0,0 +1,197 @@ ++// SPDX-License-Identifier: GPL-2.0-or-later OR MIT ++/* ++ * Broadcom BCM470X / BCM5301X ARM platform code. ++ * DTS for Meraki MR32 / Codename: Espresso ++ * ++ * Copyright (C) 2018-2020 Christian Lamparter <chunkeey@gmail.com> ++ */ ++ ++/dts-v1/; ++ ++#include "bcm4708.dtsi" ++#include "bcm5301x-nand-cs0-bch8.dtsi" ++#include <dt-bindings/leds/common.h> ++ ++/ { ++ compatible = "meraki,mr32", "brcm,brcm53016", "brcm,bcm4708"; ++ model = "Meraki MR32"; ++ ++ chosen { ++ bootargs = " console=ttyS0,115200n8 earlycon"; ++ }; ++ ++ memory { ++ reg = <0x00000000 0x08000000>; ++ device_type = "memory"; ++ }; ++ ++ aliases { ++ serial1 = &uart2; ++ }; ++ ++ leds { ++ compatible = "gpio-leds"; ++ ++ sysled3 { ++ function = LED_FUNCTION_FAULT; ++ color = <LED_COLOR_ID_AMBER>; ++ gpios = <&chipcommon 18 GPIO_ACTIVE_LOW>; ++ panic-indicator; ++ }; ++ sysled2 { ++ function = LED_FUNCTION_INDICATOR; ++ color = <LED_COLOR_ID_WHITE>; ++ gpios = <&chipcommon 19 GPIO_ACTIVE_HIGH>; ++ }; ++ }; ++ ++ keys { ++ compatible = "gpio-keys"; ++ #address-cells = <1>; ++ #size-cells = <0>; ++ ++ restart { ++ label = "Reset"; ++ linux,code = <KEY_RESTART>; ++ gpios = <&chipcommon 21 GPIO_ACTIVE_LOW>; ++ }; ++ }; ++ ++ pwm-leds { ++ compatible = "pwm-leds"; ++ ++ red { ++ /* SYS-LED 1 - Tricolor */ ++ function = LED_FUNCTION_INDICATOR; ++ color = <LED_COLOR_ID_RED>; ++ pwms = <&pwm 0 50000 0>; ++ max-brightness = <255>; ++ }; ++ ++ green { ++ /* SYS-LED 1 - Tricolor */ ++ function = LED_FUNCTION_POWER; ++ color = <LED_COLOR_ID_GREEN>; ++ pwms = <&pwm 1 50000 0>; ++ max-brightness = <255>; ++ }; ++ ++ blue { ++ /* SYS-LED 1 - Tricolor */ ++ function = LED_FUNCTION_INDICATOR; ++ color = <LED_COLOR_ID_BLUE>; ++ pwms = <&pwm 2 50000 0>; ++ max-brightness = <255>; ++ }; ++ }; ++ ++ i2c { ++ /* ++ * The platform provided I2C does not budge. ++ * This is a replacement until I can figure ++ * out what are the missing bits... ++ */ ++ ++ compatible = "i2c-gpio"; ++ sda-gpios = <&chipcommon 5 GPIO_ACTIVE_HIGH>; ++ scl-gpios = <&chipcommon 4 GPIO_ACTIVE_HIGH>; ++ i2c-gpio,delay-us = <10>; /* close to 100 kHz */ ++ #address-cells = <1>; ++ #size-cells = <0>; ++ ++ current_sense: ina219@45 { ++ compatible = "ti,ina219"; ++ reg = <0x45>; ++ shunt-resistor = <60000>; /* = 60 mOhms */ ++ }; ++ ++ eeprom: eeprom@50 { ++ compatible = "atmel,24c64"; ++ reg = <0x50>; ++ pagesize = <32>; ++ read-only; ++ }; ++ }; ++}; ++ ++&uart0 { ++ clock-frequency = <62500000>; ++ /delete-property/ clocks; ++}; ++ ++&uart1 { ++ status = "disabled"; ++}; ++ ++&uart2 { ++ status = "okay"; ++ /* ++ * bluetooth-le { ++ * compatible = "brcm,bcm20732"; ++ * enable-gpios = <&chipcommon 20 GPIO_ACTIVE_HIGH>; ++ *}; ++ */ ++}; ++ ++&gmac1 { ++ status = "disabled"; ++}; ++&gmac2 { ++ status = "disabled"; ++}; ++&gmac3 { ++ status = "disabled"; ++}; ++ ++&pwm { ++ status = "okay"; ++ pinctrl-names = "default"; ++ pinctrl-0 = <&pinmux_pwm>; ++}; ++ ++&nandcs { ++ nand-ecc-algo = "hw"; ++ ++ partitions { ++ /* ++ * The partition autodetection does not work for this device. ++ * It will only detect the "nvram" partition with an incorrect size. ++ * [ 1.721667] 1 bcm47xxpart partitions found on MTD device brcmnand.0 ++ * [ 1.727962] Creating 1 MTD partitions on "brcmnand.0": ++ * [ 1.733117] 0x000000400000-0x000008000000 : "nvram" ++ */ ++ ++ compatible = "fixed-partitions"; ++ #address-cells = <0x1>; ++ #size-cells = <0x1>; ++ ++ partition0@0 { ++ label = "u-boot"; ++ reg = <0x0 0x100000>; ++ read-only; ++ }; ++ ++ partition1@100000 { ++ label = "bootkernel1"; ++ reg = <0x100000 0x300000>; ++ read-only; ++ }; ++ ++ partition2@400000 { ++ label = "nvram"; ++ reg = <0x400000 0x100000>; ++ read-only; ++ }; ++ ++ partition3@500000 { ++ label = "bootkernel2"; ++ reg = <0x500000 0x300000>; ++ read-only; ++ }; ++ ++ partition4@800000 { ++ label = "ubi"; ++ reg = <0x800000 0x7780000>; ++ }; ++ }; ++}; |
