This patch copies over refreshed config and patches from 5.10
with the following changes:

 - dropped superfluous tc654/tc655 variant detection patch
   (tc654 support will become available upstream starting with
   5.17-rc7+).

 - dropped xhci msi(x) workaround... as the broken MSI(X)
   is now gone.

 - dropped dwc2 workaround since the driver was fixed and it
   works without it.

Please note: Netgear WNDAP660 & WNDAP620 users:

Due to the kernel's size increase, uboot will likely break
because it is overwrite the kernel during decompression.

To fix this (and debrick affected devices, no reflash
necessary), attach the RJ45-Serial-Console cable and
enter the following in the uboot prompt during bootup:

 setenv kernel_addr_r 1100000
 saveenv
 run bootcmd

to restore the old/previous behavior:

 setenv kernel_addr_r 600000
 saveenv
 run bootcmd

+Subject: hwmon: (tc654) Add thermal_cooling device support
+
+Adds thermal_cooling device support to the tc654/tc655
+driver. This make it possible to integrate it into a
+device-tree supported thermal-zone node as a
+cooling device.
+
+I have been using this patch as part of the Netgear WNDR4700
+Centria NAS Router support within OpenWrt since 2016.

+Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
+ method
+
+Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
+instruct the mkimage to use the xz compression, which isn't
+supported. This patch forces the gzip compression, which is
+supported and doesn't matter because the generated uImage for
+the apm821xx target gets ignored as the OpenWrt toolchain will
+do separate U-Boot kernel images for each device individually.
