The VAR-SOM-MX93 can integrate the WM8904, a high-performance
ultra-low-power stereo codec optimized for portable audio applications.
This patch adds the WM8904 device to the appropriate I2C bus, enables
the SAI peripheral, and introduces the sound node to expose the
sound card to the system.

The VAR-SOM-MX93 features Dual Freescale/NXP PCA9541 chip as a Power
Management Integrated circuit (PMIC).
The PMIC is programmable via the I2C interface and its associated
register map, and this patch adds its support.

Add device tree nodes for the WiFi and Bluetooth module mounted on the
VAR-SOM-MX93. The module can be based on either the NXP IW612 or IW611
chipset, depending on the configuration chosen by the customer.
Regardless of the chipset used, WiFi communicates over SDIO and Bluetooth
over UART.

In the past, CONFIG_ARCH_HAS_GIGANTIC_PAGE indicated that we support
runtime allocation of gigantic hugetlb folios. In the meantime it evolved
into a generic way for the architecture to state that it supports gigantic
hugetlb folios.
In commit fae7d834c43c ("mm: add __dump_folio()") we started using
CONFIG_ARCH_HAS_GIGANTIC_PAGE to decide MAX_FOLIO_ORDER: whether we could
have folios larger than what the buddy can handle. In the context of that
commit, we started using MAX_FOLIO_ORDER to detect page corruptions when
dumping tail pages of folios. Before that commit, we assumed that we
cannot have folios larger than the highest buddy order, which was
obviously wrong.
In commit 7b4f21f5e038 ("mm/hugetlb: check for unreasonable folio sizes
when registering hstate"), we used MAX_FOLIO_ORDER to detect
inconsistencies, and in fact, we found some now.
Powerpc allows for configs that can allocate gigantic folio during boot
(not at runtime), that do not set CONFIG_ARCH_HAS_GIGANTIC_PAGE and can
exceed PUD_ORDER.
To fix it, let's make powerpc select CONFIG_ARCH_HAS_GIGANTIC_PAGE with
hugetlb on powerpc, and increase the maximum folio size with hugetlb to 16
GiB on 64bit (possible on arm64 and powerpc) and 1 GiB on 32 bit
(powerpc). Note that on some powerpc configurations, whether we actually
have gigantic pages depends on the setting of CONFIG_ARCH_FORCE_MAX_ORDER,
but there is nothing really problematic about setting it unconditionally:
we just try to keep the value small so we can better detect problems in
__dump_folio() and inconsistencies around the expected largest folio in
the system.
Ideally, we'd have a better way to obtain the maximum hugetlb folio size
and detect ourselves whether we really end up with gigantic folios. Let's
defer bigger changes and fix the warnings first.
While at it, handle gigantic DAX folios more clearly: DAX can only end up
creating gigantic folios with HAVE_ARCH_TRANSPARENT_HUGEPAGE_PUD.
Add a new Kconfig option HAVE_GIGANTIC_FOLIOS to make both cases clearer.
In particular, worry about ARCH_HAS_GIGANTIC_PAGE only with HUGETLB_PAGE.
Note: with enabling CONFIG_ARCH_HAS_GIGANTIC_PAGE on powerpc, we will now
also allow for runtime allocations of folios in some more powerpc configs.
I don't think this is a problem, but if it is we could handle it through
__HAVE_ARCH_GIGANTIC_PAGE_RUNTIME_SUPPORTED.
While __dump_page()/__dump_folio was also problematic (not handling
dumping of tail pages of such gigantic folios correctly), it doesn't seem
critical enough to mark it as a fix.
