It has been notice a buf in L2 cache scaling where the scaling is not
done proprely if the frequency is set to the initial state before
the new frequency.
From: https://patchwork.kernel.org/patch/10565443/
* The clocks are set to aux clock rate first to make sure the
* secondary mux is not sourcing off of QSB. The rate is then set to
* two different rates to force a HFPLL reinit under all
* circumstances.
In the initial stage of boot to force a new frequency to apply, is
needed to first set the frequency back to the lowest one (aux_rate)
and then to the target one. This force and make sure the controller
actually switch the frequency to the right one. Apply the same
mechanism to L2 frequency scaling. Before scaling to the target
frequency, first set the frequency to the aux_rate to force the
transition, then scale it to the target frequency. Doing the wrong way
can produce unexpected results and could lock the scaling mechanism
until a full reboot is done (Causing a full reset by the krait-cc driver)
From: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=77612720a2362230af726baa4149c40ec7a7fb05
When the Hfplls are reprogrammed during the rate change,
the primary muxes which are sourced from the same hfpll
for higher frequencies, needs to be switched to the 'safe
secondary mux' as the parent for that small window. This
is done by registering a clk notifier for the muxes and
switching to the safe parent in the PRE_RATE_CHANGE notifier
and back to the original parent in the POST_RATE_CHANGE notifier.
This should apply also to L2 scaling... as we can't relly use
the notifier, we manually do this on L2 scaling.

Buffalo WXR-2533DHP is a 2.4/5 GHz band 11ac router, based on Qualcomm
IPQ8064.
The U-Boot on WXR-2533DHP employs a complicated dual firmware
protection scheme against corruptions of the kernel and rootfs
images. See the notes in buffalo.sh for details.
specifications:
- Qualcomm IPQ8064 (384 - 1,400 MHz, 2C2T)
- 512 MB of RAM (DDR3)
- 256 MB of Flash (NAND)
- 4T4R 2.4/5 GHz Wlan (QCA9980)
- 5x 10/100/1000 Mbps Ethernet
- 10x LEDs, 8x keys (6x buttons, 2x slide-switches)
- 2x USB 3.0 Type-A
- 12VDC/4A AC Adapter
- UART through-hole on PCB
- J3: Vcc, GND, TX, RX from USB port side
- 115200n8
Boot instructions for the initramfs image:
1. Prepare the TFTP server with the initramfs image renamed to
"wxr2300dhp-initramfs.uImage" and IP address "192.168.11.10".
2. Press the "AOSS" button while powering on the WXR-2533DHP.
3. Wait until the "Wireless" LED flashes before releasing the AOSS button.
The WXR-2533DHP will grab the image from TFTP server and will boot it.
Flashing instructions:
To persistently write the firmware, flash an openwrt sysupgrade image
from inside the initramfs, for example transfer
via `scp <sysupgrade> root@192.168.1.1:/tmp` and flash on the device
with `sysupgrade -n /tmp/<sysupgrade>`. Then wait ~120 seconds to
let it finish the flashing process.
