ath79: remove obsolete 5.15 kernel support

The 5.15 kenel config file, patches and version switches will be
removed in this patch. We will introduce kernel 6.6 support soon.

-Subject: [PATCH] ath79: add support for booting QCN550x
-
-Based on wikidevi, QCN550x is a "Dragonfly" like QCA9561 and QCA9563.
-Treating it as QCA956x seems to work.
-Tested on Netgear EX7300v2 which boots successfully with
-the same CPU clock as the stock firmware.

-
-Read back the reset register in order to flush the cache. This fixes
-spurious reboot hangs on TP-Link TL-WDR3600 and TL-WDR4300 with Zentel
-DRAM chips.
-
-This issue was fixed in the past, but switching to the reset-driver

-
-With the ath79 target getting converted to pure OF, we can drop all the
-platform data code and add the missing OF bits to the driver. We also add
-a irq domain for the PCI/e controllers cascade, thus making it usable from
-dts files.

-Subject: [PATCH 20/33] MIPS: pci-ar724x: convert to OF
-
-With the ath79 target getting converted to pure OF, we can drop all the
-platform data code and add the missing OF bits to the driver. We also add
-a irq domain for the PCI/e controllers cascade, thus making it usable from
-dts files.

-Subject: MIPS: pci-ar724x: add QCA9550 reset sequence
-
-The QCA9550 family of SoCs have a slightly different reset
-sequence compared to older chips.
-
-Normally the bootloader performs this sequence, however
-some bootloader implementation expect the operating system
-to clear the reset.
-
-Also get the resets from OF to support handling of the second
-PCIe root-complex on the QCA9558.

-Subject: [PATCH] ath79: force SGMII SerDes mode to MAC operation
-
-The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
-This only allows for 1000 Mbit/s links, however when used with an SGMII
-PHY in 100 Mbit/s link mode, the link remains dead.
-
-This strictly has nothing to do with the SerDes calibration, however it
-is done at the same point in the QCA reference U-Boot which is the
-blueprint for everything happening here. As the current state is more or
-less a hack, this should be fine.
-
-This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.

-Subject: [PATCH] ath79: port cybertan_part from ar71xx
-
-This patch ports the cybertan_part code from ar71xx and converts the
-driver to a DT-supported mtd parser. As a result, it will no longer
-add the u-boot, nvram and art partitions, which were never part of
-the special Cybertan header.
-
-Instead these partitions have to be specified in the DT, which has the
-upside of making it possible to add properties (i.e.: read-only), labels
-and references to these important partitions.
-

-Subject: [PATCH] ath79: add new OF only target for QCA MIPS silicon
-
-This target aims to replace ar71xx mid-term. The big part that is still
-missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik
-subtargets will follow.

-due to some unknown reason these register accesses sometimes fail

-
-THIS ONLY WORKS ON ATH79 AND MAY BREAK THE DRIVER ON OTHER PLATFORMS!
-The mdio bus on ath79 works in polling mode and doesn't rely on
-any interrupt. This patch breaks the driver on any mdio master
-with interrupts used.

-Subject: [PATCH] ath79: add Mikrotik rb4xx series drivers
-
-This adds 3 Mikrotik rb4xx series drivers as follows:
-
-rb4xx-cpld: This is in the mfd subsystem, and is the parent CPLD device
-that interfaces between the SoC SPI bus and its two children below.
-rb4xx-gpio: This is the GPIO expander.
-rb4xx-nand: This is the NAND driver.
-
-The history of this code comes in three phases.
-
-1. The first is a May 2015 attempt to push the equivalient ar71xx rb4xx
-drivers upstream. See https://lore.kernel.org/patchwork/patch/940880/.
-
-Module-author: Gabor Juhos <[email protected]>
-Module-author: Imre Kaloz <[email protected]>
-Module-author: Bert Vermeulen <[email protected]>
-
-2. Next several ar71xx patches were applied bringing the code current.

-From: Denis Kalashnikov <[email protected]>
-Subject: [PATCH] ath79: add support for reset key on MikroTik RB912UAG-2HPnD
-
-On MikroTik RB91x board series a reset key shares SoC gpio
-line #15 with NAND ALE and NAND IO7. So we need a custom
-gpio driver to manage this non-trivial connection schema.
-Also rb91x-nand needs to have an ability to disable a polling
-of the key while it works with NAND.
-
-While we've been integrating rb91x-key into a firmware, we've
-figured out that:
-* In the gpio-latch driver we need to add a "cansleep" suffix to
-several gpiolib calls,
-* When gpio-latch and rb91x-nand fail to get a gpio and an error
-is -EPROBE_DEFER, they shouldn't report about this, since this
-actually is not an error and occurs when the gpio-latch probe
-function is called before the rb91x-key probe.
-We fix these related things here too.
