+Subject: [PATCH] ARM: dts: BCM5301X: Linksys EA9500 add fixed partitions
+
+This router has dual paritions to store trx firmware image and
+dual partitions for nvram. The second one in each of these cases acts
+as a backup store.
+
+When tested with OpenWrt, the default partition parser causes two issues:
+
+1. It labels both nvram partitions as nvram. In factory, second one is
+labeled devinfo.
+2. It parses second trx image and tries to create second 'linux' partition
+and fails with - cannot create duplicate 'linux' partition
+
+The following patch works around both of these issues.

+The previous patch "ARM: dts: NSP: Disable PL330 by default, add

+Subject: [PATCH] ARM: dts: NSP: Move USB3 PHY to internal MDIO bus
+
+This patch largely replicates Vivek Unune's patch "ARM: dts:
+BCM5301X:Make usb3 phy use mdio phy driver"[1] for the NSP platform,
+whereby we need to create an mdio-mux to facilitate switches
+configured via external MDIO, in this case on the Meraki MX65.
+
+However in doing so, we are creating an overlap with usb3_phy's
+ccb-mii range. To resolve this, usb3_phy should be moved to a child
+node of the internal MDIO bus. The result is heavily based upon Vivek's
+patch. This has also been cross-referenced with Yendapally Reddy's
+earlier work which utilised the subsequently dropped brcm,nsp-usb3-phy
+driver: "[PATCH v2 4/4] arm: dts: nsp: Add USB nodes to device tree"
+[2]. Finally, this change provides conformance to the bcm-ns-usb3-phy
+documentation, utilising the required usb3-dmp-syscon property. Note
+that support for the deprecated ccb-mii bindings has been dropped as of
+"phy: phy-bcm-ns-usb3: drop support for deprecated DT binding"[3].

+Subject: [PATCH] ARM: dts: NSP: Add DT files for Meraki MX64 series
+
+MX64 & MX64W Hardware info:
+  - CPU: Broadcom BCM58625 Cortex A9 @ 1200Mhz
+  - RAM: 2 GB (4 x 4Gb SK Hynix H5TC4G83CFR)
+  - Storage: 1 GB (Micron MT29F8G08ABACA)
+  - Networking: BCM58625 internal switch (5x 1GbE ports)
+  - USB: 1x USB2.0
+  - Serial: Internal header
+  - WLAN(MX64W only): 2x Broadcom BCM43520KMLG on the PCI bus
+
+This patch adds the Meraki MX64 series-specific bindings. Since some
+devices make use of the older A0 SoC, changes need to be made to
+accommodate this case, including removal of coherency options and
+modification to the secondary-boot-reg.

+Subject: [PATCH] ARM: dts: NSP: Fix MDIO mux node names
+
+While functional, the mdio-mux-mmioreg binding does not conform to
+Documentation/devicetree/bindings/net/mdio-mux-mmioreg.yaml in that an
+mdio-mux compatible is also required. Without this the following output
+is observed when running dtbs_check:
+
+mdio-mux@32000: compatible: ['mdio-mux-mmioreg'] is too short
+
+This change brings conformance to this requirement and corresponds
+likewise to Rafal Milecki's change to the BCM5301x platform[1].

+Subject: [PATCH] ARM: dts: NSP: Fix MX65 MDIO mux warnings
+
+The naming of this node is based upon that of the initial EA9500 dts[1].
+However this does not conform with the mdio-mux format, yielding the
+following message when running dtbs_check:
+mdio-mii-mux: $nodename:0: 'mdio-mii-mux' does not match '^mdio-mux[\\-@]?'
+
+Secondly, this node should be moved to within the axi node and given the
+appropriate unit address. This also requires exposing the axi node via a
+label in bcm-nsp.dtsi. This fixes the following warning:
+Warning (unit_address_vs_reg): /mdio-mii-mux: node has a reg or ranges property, but no unit name
+

+snapshot with Linux 5.10 (didn't test any older kernels).
+The MR32 is able to "talk to the network" as before with
+OpenWrt's SWITCHDEV b53 driver.

+description: |
+  Broadcom's NVRAM is a structure containing device specific environment
+  variables. It is used for storing device configuration, booting parameters
+  and calibration data.
+
+  NVRAM can be accessed on Broadcom BCM47xx MIPS and Northstar ARM Cortex-A9
+  devices usiong I/O mapped memory.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Parsing every partition with "compatible" set to "brcm,trx" results in
+parsing both: firmware partition and failsafe partition on devices that
+implement failsafe booting. This affects e.g. Linksys EA9500 which has:
+
+partition@200000 {
+	reg = <0x0200000 0x01d00000>;
+	compatible = "linksys,ns-firmware", "brcm,trx";

+	reg = <0x01f00000 0x01d00000>;
+	compatible = "linksys,ns-firmware", "brcm,trx";
+};
+
+Check for MTD partition name "firmware" before parsing. Recently added
+ofpart_linksys_ns.c creates "firmware" and "failsafe" depending on
+bootloader setup.

+Subject: [PATCH] usb: xhci: add support for performing fake doorbell
+
+Broadcom's Northstar XHCI controllers seem to need a special start
+procedure to work correctly. There isn't any official documentation of
+this, the problem is that controller doesn't detect any connected
+devices with default setup. Moreover connecting USB device to controller
+that doesn't run properly can cause SoC's watchdog issues.
+
+A workaround that was successfully tested on multiple devices is to
+perform a fake doorbell. This patch adds code for doing this and enables
+it on BCM4708 family.

+Subject: [PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Broadcom devices have broken CFE (bootloader) that leaves hardware in an
+invalid state. It causes problems with booting Linux. On Northstar
+devices kernel was randomly hanging in ~25% of tries during early init.
+Hangs used to happen at random places in the start_kernel. On BCM53573
+kernel doesn't even seem to start booting.
+
+To workaround this problem we need to do following very early:
+1) Clear 2 following bits in the SCTLR register:
+#define CR_M    (1 << 0)        /* MMU enable */
+#define CR_C    (1 << 2)        /* Dcache enable */
+2) Flush the whole D-cache
+3) Disable L2 cache
+
+Unfortunately this patch is not upstreamable as it does above things
+unconditionally. We can't check if we are running on Broadcom platform
+in any safe way and doing such hacks with ARCH_MULTI_V7 is unacceptable
+as it could break other devices support.

+Subject: [PATCH] ARM: dts: BCM5301X: Specify PWM in the DT
+
+The BCM53016 in the Meraki MR32 uses the on-chip PWM
+controller to drive a tri-color RGB LED. Since I plan
+to use the PWM, I made a label for the pwm's pinmux
+node. This way, it can be easily referenced.... And
+Also included a label for the i2c since I'm going to
+need it in the future too.

+RAM:    128 MiB
+NAND:   128 MiB Spansion S34ML01G2 (~114 MiB useable)

+WIFI3:  Broadcom BCM43428 abgn (1x1:1 - id: 43428)
+
+BLE:    Broadcom BCM20732 (ttyS1)
+LEDS:   1 x Programmable RGB Status LED (driven by a PWM)
+        1 x White LED (GPIO)
+        1 x Orange LED Fault Indicator (GPIO)
+        2 x LAN Activity / Speed LEDs (On the RJ45 Port)
+BUTTON: one Reset button
+MISC:   AT24C64 8KiB EEPROM (i2c - stores Ethernet MAC)
+        ina219 hardware monitor (i2c)
+        Kensington Lock
+
+SERIAL:
+	WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
+        The Serial setting is 115200-8-N-1. The board has a populated
+        right angle 1x4 0.1" pinheader.
+        The pinout is: VCC, RX, TX, GND.
+
+Odd stuff:
+	- uart0 clock frequency is 62.5 MHz.
+	- The LEDs are labeled as SYS-LED1 through SYS-LED3
+	  because of the silkscreen on the PCB.
+	- the original u-boot has been compiled with most functions
+	  and commands disabled. 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.

+Subject: [PATCH] ARM: dts: BCM5301X: Linksys EA9500 add fixed partitions
+
+This router has dual paritions to store trx firmware image and
+dual partitions for nvram. The second one in each of these cases acts
+as a backup store.
+
+When tested with OpenWrt, the default partition parser causes two issues:
+
+1. It labels both nvram partitions as nvram. In factory, second one is
+labeled devinfo.
+2. It parses second trx image and tries to create second 'linux' partition
+and fails with - cannot create duplicate 'linux' partition
+
+The following patch works around both of these issues.

+
+BCM47094 version of pinmux uses different compatible and supports MDIO
+pinmux pins. Hence, use the correct compatible string and defines the
+MDIO pins group.

+Subject: [PATCH] ARM: dts: BCM5301X: Provide defaults ports container node
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Provide an empty 'ports' container node with the correct #address-cells
+and #size-cells properties. This silences the following warning:
+
+arch/arm/boot/dts/bcm4708-asus-rt-ac56u.dt.yaml:
+ethernet-switch@18007000: 'oneOf' conditional failed, one must be fixed:
+        'ports' is a required property
+        'ethernet-ports' is a required property
+        From schema:

+Content-Transfer-Encoding: 8bit
+
+Partitions are basically fixed indeed but firmware ones don't have
+hardcoded function ("firmware" vs "failsafe"). Actual function depends
+on bootloader configuration. Use a proper binding for that.
+
+While at it fix numbers formatting to avoid:
+arch/arm/boot/dts/bcm47094-linksys-panamera.dt.yaml: partitions: 'partition@1F00000' does not match any of the regexes: '^partition@[0-9a-f]+$', 'pinctrl-[0-9]+'
