RAM and up to 128GB of storage, a USB 3.0 Host Hub and 2.0 OTG, two
Gigabit Ethernet PHYs, a 10 Gigabit Ethernet interface, an I2C EEPROM
and Temperature Sensor, an RX8130 RTC, a Quad/Dual lane CSI interface,
and some optional addons: TPM 2.0, DSI, LVDS, DisplayPort (through a

The SPI IP design for the cix sky1 SoC uses a FIFO with a data width
of 32 bits, instead of the default 8 bits. Therefore, a compatible
string is added to specify the FIFO data width configuration for the

Add PCIe RC support on Orion O6 board.
The Orion O6 board includes multiple PCIe root complexes. The current
device tree configuration enables detection and basic operation of PCIe
endpoints on this platform.
GPIO and pinctrl subsystems for this platform are not yet ready for
upstream inclusion. Consequently, attributes such as reset-gpios and
pinctrl configurations are temporarily omitted from the PCIe node
definitions.
Endpoint detection and functionality are confirmed to be operational with
this basic configuration. The missing GPIO and pinctrl support will be
added incrementally in future patches as the dependent subsystems become
available upstream.

INVALID_PHYS_ADDR has very similar definitions across the code base.
Hence just move that inside header <liux/mm.h> for more generic usage.
Also drop the now redundant ones which are no longer required.

Introduce a new IOMMU interface to flush IOTLB paging cache entries for
the CPU kernel address space. This interface is invoked from the x86
architecture code that manages combined user and kernel page tables,
specifically before any kernel page table page is freed and reused.
This addresses the main issue with vfree() which is a common occurrence
and can be triggered by unprivileged users. While this resolves the
primary problem, it doesn't address some extremely rare case related to
memory unplug of memory that was present as reserved memory at boot, which
cannot be triggered by unprivileged users. The discussion can be found at
the link below.
Enable SVA on x86 architecture since the IOMMU can now receive
notification to flush the paging cache before freeing the CPU kernel page
table pages.

The kernel's memory management subsystem provides a dedicated interface,
pagetable_free(), for freeing page table pages. Updates two call sites to
use pagetable_free() instead of the lower-level __free_page() or
free_pages(). This improves code consistency and clarity, and ensures the
correct freeing mechanism is used.

There are a billion ways to refer to a physical memory address. One of
the x86 PMD freeing code location chooses to use a 'pte_t *' to point to a
PMD page and then call a PTE-specific freeing function for it. That's a
bit wonky.
Just use a 'struct ptdesc *' instead. Its entire purpose is to refer to
page table pages. It also means being able to remove an explicit cast.
Right now, pte_free_kernel() is a one-liner that calls
pagetable_dtor_free(). Effectively, all this patch does is remove one
superfluous __pa(__va(paddr)) conversion and then call
pagetable_dtor_free() directly instead of through a helper.

The only instances in which we customise this function are ones in which we
customise the PFN used.
Instances where architectures were not passing the pgprot value through
pgprot_decrypted() are ones where pgprot_decrypted() was a no-op anyway, so
we can simply always pass pgprot through this function.
Use this fact to simplify the use of io_remap_pfn_range(), by abstracting
the PFN via io_remap_pfn_range_pfn() and using this instead of providing a
general io_remap_pfn_range() function per-architecture.

Patch series "drivers/base/node: fold node register and unregister
functions", v2.
The first patch merges register_one_node() and register_node(), leaving a
single register_node() function.
The second patch merges unregister_one_node() and unregister_node(),
leaving a single unregister_node() function.
There are no functional changes in these patches.
This patch (of 2):
register_node() is only called from register_one_node(). This patch folds
register_node() into its only caller and renames register_one_node() to
register_node().
This reduces unnecessary indirection and simplifies the code structure.
No functional changes are introduced.

mm_get_unmapped_area() is a wrapper around arch_get_unmapped_area() /
arch_get_unmapped_area_topdown(), both of which search current->mm for
some free space. Neither take an mm_struct - they implicitly operate on
current->mm.
But the wrapper takes an mm_struct and uses it to decide whether to search
bottom up or top down. All callers pass in current->mm for this, so
everything is working consistently. But it feels like an accident waiting
to happen; eventually someone will call that function with a different mm,
expecting to find free space in it, but what gets returned is free space
in the current mm.
So let's simplify by removing the parameter and have the wrapper use
current->mm to decide which end to start at. Now everything is consistent
and self-documenting.

the AP using AUDIOMIX MU, for instance). To do so, the security-related
registers of the bridge have to be configured before the DSP is started.

Currently, the sbi_init() always attempts to register the legacy shutdown
function as the sys-off handler which is fine when RISCV_SBI_V01 is not
enabled. However, if RISCV_SBI_V01 is enabled in the kernel and the SBI
v0.1 is not supported by the underlying SBI implementation then the
legacy shutdown fails. Fix this by not registering the legacy shutdown
when SRST shutdown is available.
Fixes: 70ddf86d76c1 ("riscv: sbi: Switch to new sys-off handler API")

According to the board design, set SEL to high means flipped
connection (TX2/RX2). And the TCPM will output logical 1 if it needs
flipped connection. So switch to active high for select-gpios.
The EN pin on mux chip is low active, so switch to active low for
enable-gpios too.

Make SoM .dtsi SoC-agnostic by moving SoC include to board level
imx6qdl-var-som.dtsi currently includes imx6q.dtsi, which makes this SoM
description Quad/Dual specific and prevents reuse from i.MX6DL boards.
Changes:
- Move imx6q.dtsi include from imx6qdl-var-som.dtsi to
imx6q-var-mx6customboard.dts.
- Remove /dts-v1/; from imx6qdl-var-som.dtsi (dtsi files should not declare
version)
This keeps the SoM .dtsi SoC-agnostic (it already relies on imx6qdl.dtsi for
family-common parts) and allows boards using the DualLite or Solo to include
imx6dl.dtsi instead.
Why this is needed:
To reuse imx6qdl-var-som.dtsi on i.MX6DL board.
No functional changes for imx6q-var-mx6customboard are intended.

The VAR-SOM-MX93 integrates an ADS7846 resistive touchscreen controller.
The controller is physically located on the SOM, and its signals are
routed to the SOM pins, allowing carrier boards to make use of it.
This patch adds the ADS7846 node and the appropriate SPI controller.
