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 -Signed-off-by: Florian Fainelli - ---- 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 -+ */ -+ -+/dts-v1/; -+ -+#include "bcm4708.dtsi" -+#include "bcm5301x-nand-cs0-bch8.dtsi" -+#include -+ -+/ { -+ 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 = ; -+ gpios = <&chipcommon 18 GPIO_ACTIVE_LOW>; -+ panic-indicator; -+ }; -+ sysled2 { -+ function = LED_FUNCTION_INDICATOR; -+ color = ; -+ gpios = <&chipcommon 19 GPIO_ACTIVE_HIGH>; -+ }; -+ }; -+ -+ keys { -+ compatible = "gpio-keys"; -+ #address-cells = <1>; -+ #size-cells = <0>; -+ -+ restart { -+ label = "Reset"; -+ linux,code = ; -+ gpios = <&chipcommon 21 GPIO_ACTIVE_LOW>; -+ }; -+ }; -+ -+ pwm-leds { -+ compatible = "pwm-leds"; -+ -+ red { -+ /* SYS-LED 1 - Tricolor */ -+ function = LED_FUNCTION_INDICATOR; -+ color = ; -+ pwms = <&pwm 0 50000 0>; -+ max-brightness = <255>; -+ }; -+ -+ green { -+ /* SYS-LED 1 - Tricolor */ -+ function = LED_FUNCTION_POWER; -+ color = ; -+ pwms = <&pwm 1 50000 0>; -+ max-brightness = <255>; -+ }; -+ -+ blue { -+ /* SYS-LED 1 - Tricolor */ -+ function = LED_FUNCTION_INDICATOR; -+ color = ; -+ 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>; -+ }; -+ }; -+};
