The MBL has a 512KiB Microchip SST39VF040 chip for uboot and

Thanks to Ewald who figured out that the "jedec-probe" vs.
"jedec-flash" was the wrong binding. With this information
and the jedec-probe support enabled => the chip works.

b0d5939b80 apm821xx: WNDR4700: use upstream tc654 cooling devices
Upstream hwmon-maintainer had various comments about
the changes to the tc654 driver. These have been
addressed and the cooling device support is destined
for inclusion.

One of the comments was the change of the cooling states
scaling. No longer the driver uses the same values as the
hwmon interface, instead the states are now the 17 states
the tc654 supports.

832b9cbd74 apm821xx: fix WD MyBook Live DUO USB-Port
where to begin? the USB regulator settings were just
a part of the issue. With them changed, according to
the forum it still failed when a USB device was
connected to the port with:

dwc2 4bff80000.usbotg: dwc2_restore_global_registers: no global registers to restore
dwc2 4bff80000.usbotg: dwc2_exit_partial_power_down: failed to restore registers
dwc2 4bff80000.usbotg: exit partial_power_down failed
dwc2 4bff80000.usbotg: HC died; cleaning up

One clue was found upstream in
commit cc10ce0c51b1 ("usb: dwc2: disable power_down on Amlogic devices")

|Disable power_down by setting the parameter to
|DWC2_POWER_DOWN_PARAM_NONE. This fixes a problem on various Amlogic
|Meson SoCs where USB devices are only recognized when plugged in before
|booting Linux. A hot-plugged USB device was not detected even though the
|device got power (my USB thumb drive for example has an LED which lit

the same method proposed there worked with APM821xx's USB IP-Core.

8b0c053671 apm821xx: implement new LED label naming scheme
This patch updates all current APM82181 devices over to that
"new LED naming scheme". This includes many updates to the
device-tree:
	- dropped the deprecated, but beloved "label" property.
	- rename all DT leds node names to led-#.
	- add function and color properties.
	- utilized panic-indicator property.
	- dropped led- aliases (see below).

migration scripts for all devices are included.

For more information. See:
<https://www.kernel.org/doc/html/latest/leds/leds-class.html>

For the future: It looks like the color+function properties
won over the dt-alias / label. This will need to be wired up
into openwrt eventually. For APM821xx the situation is that
all devices have a dedicated power and fault indicator.

bbb3852401 apm821xx: MBL: HDD regulators overhaul for MBL DUO
Takimata reported on the OpenWrt forum in thread [0], that his
MyBook Live Duo wasn't booting OpenWrt 21.02 after upgrading
from the previous OpenWrt 19.07.

The last logged entries on his console

|[    0.531599] sata1-regulator GPIO handle specifies active low - ignored
|[    0.538391] sata0-regulator GPIO handle specifies active low - ignored
|[    0.759791] ata2: SATA link down (SStatus 0 SControl 300)
|[    0.765251] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
|[    5.909555] ata1.00: qc timeout (cmd 0xec)

|[    6.231757] ata1: SATA link down (SStatus 0 SControl 300)

This extract clearly showed that the HDD on which OpenWrt is installed,
simply disappeared after the SATA power regulators had been initialized.

The reason why this worked with OpenWrt 19.07 was because the kernel
config symbol CONFIG_REGULATOR=y was not set in the target's config-4.14.

(This shows that the MBL Single does differ from the DUO in that
it does not have programmable power regulators for the HDDs.)

7a6a349445 apm821xx: WNDAP620 + WNDAP660: reorganize partitions for 5.10
Due to 5.10 increased kernel size, the current 4MiB-ish kernel
partition got too small. Luckily, netgear's uboot environment
is setup to read 0x60000 bytes from the kernel partition location.

... While at it: also do some cleanups in the DTS in there.

The original (re-)installation described in
commit d82d84694e ("apm821xx: add support for the Netgear WNDAP620 and WNDAP660")
seemed to be still working for now. What I noticed though
is that the bigger initramfs images needed to use a different
destination address (1000000) to prevent it overwriting
itself during decompression. i.e:
 # tftp 1000000 openwrt-...-wndap620-initramfs-kernel.bin
 # bootm

However, in case of the WNDAP620+660 the factory.img image can be
written directly to the flash through uboot.

df07bafcd2 apm821xx: MBL: correct phy-mode delay settings
This came up in an upstream commit: "
b1dd9bf688b0 "net: phy: broadcom: Fix RGMII delays for BCM50160 and BCM50610M"

The PHY driver entry for BCM50160 and BCM50610M calls
bcm54xx_config_init() but does not call bcm54xx_config_clock_delay() in
order to configuration appropriate clock delays on the PHY, fix that."

So the "rgmii" phy-mode has always been wrong, but went unnoticed since
the broadcom phy driver didn't push the delay settings to the chip.

252197f014 apm821xx: provide legacy interrupts for PCIe in DT
Devices with PCIe-Switches like the WNDR4700, MR24 and WNDAP660
need to have the interrupts property specified in the device-tree
for the legacy pci interrupt signaling method to work.

If the proper interrupt value is not specified, the default INTA
IRQ 12 is taken for all devices. This is especially bad, if the
device is setup to use INTC, because these interrupts will not
be serviced.

Russell Senior reported his experience on the MR24:
"The symptom is client devices can't see the beacons.
Wifi ifaces appear, can scan and hear other networks,
but clients can't see the MR24's SSIDs."

(The interrupts-property on the WNDAP620 was optional since it
uses INTA by default. Likewise the MX60W is in the same category)

3509d4ec56 apm821xx: wndr4700: add preliminary drivetemp sensor
This patch prepares the WNDR4700 to use the HDD sensor for
the thermal zone. While the kernel's thermal.txt device-tree
binding documentation files talks about supporting multiple
sensors for a zone. This sadly is NOT the case. Even the most
current upstream kernels (5.6-rc) supports just >one< sensor
per zone: (driver/base/of-thermal.c:886)
| * REVIST: for now, the thermal framework supports only
| * one sensor per thermal zone. Thus, we are considering
| * only the first two values as slope and offset.

I do hope that this warning will prevent others wasteing time
on trying to figure out why their multi-sensor thermal-zones
definitions are not working as specified.

971f31bedc apm821xx: fix bogus key-presses on boot
"There are often transient line events when

clear any interrupt flags in hardware before

This patch adds a fix for the APM821XX's interrupt
controller to clear any bogus pending toggled
interrupts that happens on various APM821XX boards
on boot.

The patch also changes the debouce-interval from the
default 5ms debounce interval to 60ms all around.

state became stuck in a pressed state, even though the
button was released.

d82d84694e apm821xx: add support for the Netgear WNDAP620 and WNDAP660
This patch adds support for the Netgear WNDAP620 and WNDAP660,
they are similar devices, but due to the LAN LED configuration,
the switch setup and WIFI configuration each gets a different
device target.

Hardware Highlights WNDAP620:
CPU: AMCC PowerPC APM82181 at 1000 MHz
DRAM:  128 MB, 2 x 64 MiB DDR2 Hynix H5PS5162GF
CPU: AMCC PowerPC APM82181 at 1000 MHz
FLASH: 32 MiB, NAND SLC, Hynix HY27US08561A
Ethernet: RealTek RTL8363SB 2x2-Port Switch PHY - Only 1 GBit Port (POE)
Wifi: Atheros AR9380 minipcie - Dual-Band - 3x3:3
Serial: console port with RJ45 Interface (9600-N-8-1)
LEDS: Power, LAN-Activity, dual color LAN-Linkspeed, 2.4GHz, 5GHz LEDs
Button: Soft Reset Button
Antennae: 3 internal dual-band antennae + 3 x RSMA for external antennaes

Hardware Highlights WNDAP660:
CPU: AMCC PowerPC APM82181 at 1000 MHz + 2 Heatsinks
DRAM:  256 MB, 2 x 128 MiB DDR2
FLASH: 32 MiB, NAND SLC, Hynix HY27US08561A
Ethernet: RealTek RTL8363SB 2x2-Port Switch PHY (POE)
Wifi1: Atheros AR9380 minipcie - Dual-Band - 3x3:3
Wifi2: Atheros AR9380 minipcie - Dual-Band - 3x3:3
Serial: console port with RJ45 Interface (9600-N-8-1)
LEDS: Power, LAN-Activity, 2x dual color LAN-Linkspeed, 2.4GHz, 5GHz LEDs
Button: Soft Reset Button
Antennae: 6 internal dual-band antennae + 3 x RSMA for external antennaes

Flashing requirements:

 - needs a tftp server at 192.168.1.10/serverip.
 - special 8P8C(aka RJ45)<->D-SUB9 Console Cable
   ("Cisco Console Cable"). Note: Both WNDAP6x0 have
   a MAX3232 transceivers, hence no need for any separate
   CMOS/TTL level shifters.

External Antenna:
The antennae mux is controlled by GPIO 11 and GPIO14. Valid Configurations:
 = Config# = | = GPIO 11 = | = GPIO 14 = |  ===== Description =====
      1.     |   1 / High  |  0 / Low    | Use the internal antennae (default)
      2.     |   0 / Low   |  1 / High   | Use the external antennae

The external antennaes are only meant for the 2.4 GHz band.

One-way Flashing instructions via u-boot:

 0. connect the serial cable to the RJ45 Console Port
    Note: This requires a poper RS232 and not a TTL/USB adaptor.

 1. power up the AP and interrupt the u-boot process at

    'Hit any key to stop autoboot'

 2. setup serverip and ipaddr env settings
    Enter the following commands into the u-boot shell
    # setenv ipaddr 192.168.1.1
    # setenv serverip 192.168.1.10

 3. download the factory.img image to the AP
    Enter the following commands into the u-boot shell

    # tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-squashfs-factory.img

 4. verfiy image integrity
    Enter the following commands into the u-boot shell

    # crc32 $fileaddr $filesize

    If the calculated crc32 checksum does not match, go back to step 3.

 5. flash the image
    Enter the following commands into the u-boot shell

    # nand erase 0x110000 0x1bd0000
    # nand write ${kernel_addr_r} 0x110000 ${filesize}

 6. setup uboot environment
    Enter the following commands into the u-boot shell

    # setenv bootargs
    # setenv fileaddr
    # setenv filesize
    # setenv addroot 'setenv bootargs ${bootargs} root=/dev/ubiblock0_0'
    # setenv owrt_boot 'nboot ${kernel_addr_r} nand0 0x110000; run addroot; run addtty; bootm ${kernel_addr_r}'
    # setenv bootcmd 'run owrt_boot'
    # saveenv

 7. boot
    # run bootcmd

Booting initramfs instructions via u-boot:

 Follow steps 0 - 2 from above.

 3. boot initramfs
    Enter the following commands into the u-boot shell

    # tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-initramfs-kernel.bin
    # run addtty
    # bootm ${kernel_addr_r}

fc70276e6c apm821xx: add disk-activity triggers via DT.
The WNDR4700 and the MBL have a dedicated HDD activity LED.
This patch adds the default led triggers to the DTS and
removes the entries in 01_leds.

1d5d77612f apm821xx: apm82181.dtsi overhaul
- order entries by mmio address where possible

 - switch to lower-case address values

 - comment on BSP u-boot behaviour in regards to
   what it edits and look for

 - annotate irq lines with the help of interrupt-names

 - remove deprecated "device_type" properties
   The pci and network device_type had to stay since
   they are required by the drivers and u-boot.
   the cpu and memory device_types will remain as well
   as they are still part of the DT Spec.

9ca82c2374 apm821xx: force WNDR4700 console to 115200n8
With the upcoming 4.19 release, the serial console on the
Netgear WNDR4700 would no longer work as it is never really
set and always relied on the kernel's serial code not to
change the baud rate.

On the stock firmware, Netgear forced the console setting
through a custom CONFIG_CMDLINE in their kernel to 115200.
Normally, they should have done it in a different way and
just passed the baudrate through a "console=..." kernel
parameter via the bootargs in the "/chosen" dt node.
But in their default u-boot bootcmd setting, they somehow
forgot to add the "run addtty", so there's no easy way to
pass the baudrate from u-boot to the kernel. So it has
to be forced as otherwise it ends up as 9600 baud.
