IoT: Bluetooth 5, Zigbee and Thread (NXP K32W041)
LED: 1x RGB status (NXP PCA9633)
USB: 1x USB 3.0
Button: WPS, Reset

Flash instructions:
========
1. Manually upgrade firmware using openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin image.
More details can be found here: https://www.linksys.com/support-article?articleNum=47547
After first boot check actual partition:
- fw_printenv -n boot_part
and install firmware on second partition using command in case of 2:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
and in case of 1:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel

2. Installation using serial connection from OEM firmware (default login: root, password: admin):
- fw_printenv -n boot_part
In case of 2:
- flash_erase /dev/mtd21 0 0
- nandwrite -p /dev/mtd21 openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin
or in case of 1:
- flash_erase /dev/mtd23 0 0
- nandwrite -p /dev/mtd23 openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin
After first boot install firmware on second partition:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
or:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel

3. Installation from initramfs image using USB drive:
Put the initramfs image on the USB drive:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_mx8500-initramfs-uImage.itb of=/dev/sda
Stop u-boot and run:
- usb start && usbboot $loadaddr 0 && bootm $loadaddr
Write firmware to the flash from initramfs:
- mtd -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
and:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel

4. Back to the OEM firmware:
- mtd -e kernel -n write FW_MX8500_1.0.11.208937_prod.img kernel
and:
- mtd -r -e alt_kernel -n write FW_MX8500_1.0.11.208937_prod.img alt_kernel

5. USB recovery:
Put the initramfs image on the USB:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_mx8500-initramfs-uImage.itb of=/dev/sda
Set u-boot env:
- fw_setenv bootusb 'usb start && usbboot $loadaddr 0 && bootm $loadaddr'
- fw_setenv bootcmd 'run bootusb; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'

AQR firmware:
========
1. Firmware loading:
To properly load the firmware and initialize AQR PHY, we must use the u-boot aq_load_fw function.
To do this, you need to modify u-boot env:
With USB recovery:
- fw_setenv bootcmd 'aq_load_fw; run bootusb; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'
and without:
- fw_setenv bootcmd 'aq_load_fw; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'

2. Firmware updating:
Newer firmware (AQR-G4_v5.6.5-AQR_WNC_SAQA-L2_GT_ID45287_VER24005.cld) is available in the latest OEM firmware.
To load this firmware via u-boot, we need to add the MBN header and update 0:ethphyfw partition.
For MBN header we can use script from this repository: https://github.com/testuser7/aqr_mbn_tool
- python aqr_mbn_tool.py AQR-G4_v5.6.5-AQR_WNC_SAQA-L2_GT_ID45287_VER24005.cld
To update partition we need to install kmod-mtd-rw package first:
- insmod mtd-rw.ko i_want_a_brick=1
- mtd -e /dev/mtd26 -n write aqr_fw.mbn /dev/mtd26

96e402aef7 ipq806x: mr42/mr52: fix PCIe ports
All three PCIe ports are reported non working on Meraki MR42/MR52 boards
since kernel 6.1 with the issue of PCIe PHY link never coming up thus
no WLAN cards are available on the boards.

After debugging it seems that PCIe worked on 5.15 and older purely by
accident as device DTS was using /delete-property/ perst-gpios; in each
of the 3 PCIe nodes but there was no "perst-gpios" property in the SoC DTSI
as it was still using the older "perst-gpio" property so it was not getting
removed from the device DTS.

However, in kernel 6.1 commit ("ARM: dts: qcom-*: replace deprecated
perst-gpio with perst-gpios") updated all Qualcomm DTS-es to use the newer
"perst-gpios" and thus once ipq806x moved to 6.1 PCIe stopped working as
now that property was being dropped from the device DTS.

So, since the removal of PERST pins seems to have been wrong from the start
lets drop the property removal from MR42/MR52.

ff3d0de095 ramips: Fix wmac dts definition for TP-Link TL-MR6400 v4 and v5
This code assumed that the mt7628an_tplink_8m.dtsi file defines
mediatek,mtd-eeprom for the wmac and sets status to okay.

The mediatek,mtd-eeprom definition was removed in commit e93f41adee
("ramips: convert MT7628 EEPROM to NVMEM format") but the dts for these
two devices was not adapted to include the eeprom position on its own.

The status = "okay" property was removed in 0a1d15642f ("ramips:
mt7628: use nvmem-layout"), but the property was not added to these dts
files.

Without this change wifi does not work for these devices.

Fixes: 0a1d15642f ("ramips: mt7628: use nvmem-layout")

cffd3ad8d7 lantiq: add patch to fix the reset gpio handling in the pci driver
Linux kernel commit 90c2d2eb7ab5 ("MIPS: pci: lantiq: switch to using
gpiod API") not only switched to the gpiod API, but also inverted /
changed the polarity of the GPIO.

According to the PCI specification, the RST# pin is an active-low
signal. However, most of the device trees that have been widely used for
a long time (mainly in the openWrt project) define this GPIO as
active-high and the old driver code inverted the signal internally.

Apparently there are actually boards where the reset gpio must be
operated inverted. For this reason, we cannot use the GPIOD_OUT_LOW/HIGH
flag for initialization. Instead, we must explicitly set the gpio to
value 1 in order to take into account any "GPIO_ACTIVE_LOW" flag that
may have been set.

In order to remain compatible with all these existing device trees, we
should therefore keep the logic as it was before the commit.
