kernel/ipq40xx: Restore kernel files for v6.1
This is an automatically generated commit which aids following Kernel patch history,
as git will see the move and copy as a rename thus defeating the purpose.
See: https://lists.openwrt.org/pipermail/openwrt-devel/2023-October/041673.html

+Subject: [PATCH] firmware: qcom_scm: disable SDI if required
+
+IPQ5018 has SDI (Secure Debug Image) enabled by TZ by default, and that
+means that WDT being asserted or just trying to reboot will hang the board
+in the debug mode and only pulling the power and repowering will help.
+Some IPQ4019 boards like Google WiFI have it enabled as well.
+
+Luckily, SDI can be disabled via an SCM call.
+
+So, lets use the boolean DT property to identify boards that have SDI
+enabled by default and use the SCM call to disable SDI during SCM probe.
+It is important to disable it as soon as possible as we might have a WDT
+assertion at any time which would then leave the board in debug mode,
+thus disabling it during SCM removal is not enough.

+Subject: [PATCH 2/2] clk: fix apss cpu overclocking
+
+There's an interaction issue between the clk changes:"
+clk: qcom: ipq4019: Add the apss cpu pll divider clock node
+clk: qcom: ipq4019: remove fixed clocks and add pll clocks
+" and the cpufreq-dt.
+
+cpufreq-dt is now spamming the kernel-log with the following:
+
+[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
+for freq 761142857 (-34)
+
+This only happens on certain devices like the Compex WPJ428
+and AVM FritzBox!4040. However, other devices like the Asus
+RT-AC58U and Meraki MR33 work just fine.
+
+The issue stem from the fact that all higher CPU-Clocks
+are achieved by switching the clock-parent to the P_DDRPLLAPSS
+(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
+as part of the DDR calibration.
+
+For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
+at round 533 MHz (ddrpllsdcc = 190285714 Hz).
+
+whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
+clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
+
+This patch attempts to fix the issue by modifying
+clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
+to use a new qcom_find_freq_close() function, which returns the closest
+matching frequency, instead of the next higher. This way, the SoC in
+the FB4040 (with its max clock speed of 710.4 MHz) will no longer
+try to overclock to 761 MHz.
+

+Subject: [PATCH] arm: compressed: add appended DTB section
+
+This adds a appended_dtb section to the ARM decompressor
+linker script.
+
+This allows using the existing ARM zImage appended DTB support for
+appending a DTB to the raw ELF kernel.
+
+Its size is set to 1MB max to match the zImage appended DTB size limit.
+
+To use it to pass the DTB to the kernel, objcopy is used:
+
+objcopy --set-section-flags=.appended_dtb=alloc,contents \
+ --update-section=.appended_dtb=<target>.dtb vmlinux
+
+This is based off the following patch:

+
+For IPQ40XX systems where the SoC watchdog is activated before linux,
+the watchdog timer may be too small for linux to finish uncompress,
+boot, and watchdog management start.
+If the watchdog is enabled, set the timeout for it to 30 seconds.
+The functionality and offsets were copied from:
+drivers/watchdog/qcom-wdt.c qcom_wdt_set_timeout & qcom_wdt_start
+The watchdog memory address was taken from:
+arch/arm/boot/dts/qcom-ipq4019.dtsi
+
+This was required on Mikrotik IPQ40XX consumer hardware using Mikrotik's
+RouterBoot bootloader.

+This effectively reverts upstream Linux commit 13e77747800e ("firmware:

+firmwares don't support the atomic variant.

+Subject: [PATCH] net: ipqess: introduce the Qualcomm IPQESS driver
+
+The Qualcomm IPQESS controller is a simple 1G Ethernet controller found
+on the IPQ4019 chip. This controller has some specificities, in that the
+IPQ4019 platform that includes that controller also has an internal
+switch, based on the QCA8K IP.
+
+It is connected to that switch through an internal link, and doesn't
+expose directly any external interface, hence it only supports the
+PHY_INTERFACE_MODE_INTERNAL for now.
+
+It has 16 RX and TX queues, with a very basic RSS fanout configured at
+init time.

+Subject: [PATCH] net: dsa: add out-of-band tagging protocol
+
+This tagging protocol is designed for the situation where the link
+between the MAC and the Switch is designed such that the Destination
+Port, which is usually embedded in some part of the Ethernet Header, is
+sent out-of-band, and isn't present at all in the Ethernet frame.
+
+This can happen when the MAC and Switch are tightly integrated on an
+SoC, as is the case with the Qualcomm IPQ4019 for example, where the DSA
+tag is inserted directly into the DMA descriptors. In that case,
+the MAC driver is responsible for sending the tag to the switch using
+the out-of-band medium. To do so, the MAC driver needs to have the
+information of the destination port for that skb.
+
+Add a new tagging protocol based on SKB extensions to convey the
+information about the destination port to the MAC driver

+Subject: [PATCH] net: ipqess: Add out-of-band DSA tagging support
+
+On the IPQ4019, there's an 5 ports switch connected to the CPU through
+the IPQESS Ethernet controller. The way the DSA tag is sent-out to that
+switch is through the DMA descriptor, due to how tightly it is
+integrated with the switch.
+
+We use the out-of-band tagging protocol by getting the source
+port from the descriptor, push it into the skb extensions, and have the
+tagger pull it to infer the destination netdev. The reverse process is
+done on the TX side, where the driver pulls the tag from the skb and
+builds the descriptor accordingly.

+
+The Qualcomm IPQ4019 includes an internal 5 ports switch, which is
+connected to the CPU through the internal IPQESS Ethernet controller.
+
+Add support for this internal interface, which is internally connected to a

+
+This Ethernet controller only support a specific internal interface mode

+Subject: [PATCH] net: dsa: qca8k: add IPQ4019 built-in switch support
+
+Qualcomm IPQ40xx SoC-s have a variant of QCA8337N switch built-in.
+
+It shares most of the stuff with its external counterpart, however it is
+modified for the SoC.
+Namely, it doesn't have second CPU port (Port 6), so it has 6 ports
+instead of 7.
+It also has no built-in PHY-s but rather requires external PSGMII based
+companion PHY-s (QCA8072 and QCA8075) for which it first needs to carry
+out calibration before using them.
+PSGMII has a SoC built-in PHY that is used to connect to the PHY-s which
+unfortunately requires some magic values as the datasheet doesnt document
+the bits that are being set or the register at all.
+
+Since its built-in it is MMIO like other peripherals and doesn't have its
+own MDIO bus but depends on the SoC provided one.
+
+CPU connection is at Port 0 and it uses some kind of a internal connection
+and no traditional RGMII/SGMII.
+
+It also doesn't use in-band tagging like other qca8k switches so a out of
+band based tagger is used.

+
+Add QCA8075 PHY Package nodes. The PHY nodes that were previously
+defined never worked and actually never had a driver to correctly setup
+these PHY. Now that we have a correct driver, correctly add the PHY
+Package node and set the default value of 300mw for tx driver strength
+following specification of ipq4019 SoC.

+Subject: [PATCH] net: qualcomm: ipqess: fix TX timeout errors
+
+Currently logic to handle napi tx completion is flawed and on the long
+run on loaded condition cause TX timeout error with the queue not being
+able to handle any new packet.
+
+There are 2 main cause of this:
+- incrementing the packet done value wrongly
+- handling 2 times the tx_ring tail
+
+ipqess_tx_unmap_and_free may return 2 kind values:
+- 0: we are handling first and middle descriptor for the packet
+- packet len: we are at the last descriptor for the packet
+
+Done value was wrongly incremented also for first and intermediate
+descriptor for the packet resulting causing panic and TX timeouts by
+comunicating to the kernel an inconsistent value of packet handling not
+matching the expected ones.
+
+Tx_ring tail was handled twice for ipqess_tx_complete run resulting in
+again done value incremented wrongly and also problem with idx handling
+by actually skipping descriptor for some packets.
+
+Rework the loop logic to fix these 2 problem and also add some comments
+to make sure ipqess_tx_unmap_and_free ret value is better
+understandable.
