5f60d5f6bb move asm/unaligned.h to linux/unaligned.h
asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

b8979c6b4d soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
 is many of the SoC specific drivers, both the custom drivers/soc
 ones and the closely related subsystems (memory, bus, firmware,
 reset, ...).
 
 The at91 platform gains support for sam9x7 chips in the soc and
 power management code. This is the latest variant of one of the
 oldest still supported SoC families, using the ARM9 (ARMv5) core.
 
 As usual, the qualcomm snapdragon platform gets a ton of updates in many
 of their drivers to add more features and additional SoC support. Most
 of these are somewhat firmware related as the platform has a number of
 firmware based interfaces to the kernel. A notable addition here is the
 inclusion of trace events to two of these drivers.
 
 Herve Codina and Christophe Leroy are now sending updates for
 drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
 and Arm specific platforms and has previously been problematic to
 maintain. The first update here contains support for newer PowerPC
 variants and some cleanups.
 
 The turris mox firmware driver has a number of updates, mostly cleanups.
 
 The Arm SCMI firmware driver gets a major rework to modularize
 the existing code into separately loadable drivers for the various
 transports, the addition of custom NXP i.MX9 interfaces and a
 number of smaller updates.
 
 The Arm FF-A firmware driver gets a feature update to support
 the v1.2 version of the specification.
 
 The reset controller drivers have some smaller cleanups and a newly
 added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
 
 The memory controller drivers get some cleanups and refactoring
 for Tegra, TI, Freescale/NXP and a couple more platforms.
 
 Finally there are lots of minor updates to firmware (raspberry pi,
 tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
 mediatek) drivers and their DT bindings.

platform: cznic: turris-omnia-mcu: fix HW_RANDOM dependency
There is still a build failure when the rwrng support is in a loadable
module but the mcu driver is built-in:

arm-linux-gnueabi-ld: drivers/platform/cznic/turris-omnia-mcu-trng.o: in function `omnia_mcu_register_trng':
turris-omnia-mcu-trng.c:(.text.omnia_mcu_register_trng+0x11c): undefined reference to `devm_hwrng_register'

Change the dependency to explicitly disallow the broken
configuration.

The problem here is that it selects entire subsystems, which normal

instead.
