* [DM/OFW][PCI] Fix address translation and PCI resource enumeration
Rework OFW address translation to walk nested bus ranges in the correct
direction and cache "ranges" and "dma-ranges" independently. Handle PCI
three-cell addresses without treating the PCI flags cell as part of the
address, and fix CPU-to-DMA and DMA-to-CPU translation across nested
buses.
Fix PCI BAR sizing and assignment by disabling address decoding during
probing, preserving BAR attribute bits, and programming 64-bit BARs
correctly. Add device enable and disable helpers so resources and bus
mastering are enabled before driver probe.
Program bridge memory and prefetch windows while scanning downstream
buses, correctly link child buses into the PCI bus hierarchy, and avoid
unnecessary PCIe link retraining when the link is already active.
Allow host bridges without a device-tree pci-domain property by
allocating unique domains dynamically, while preserving explicit domain
assignments.
Fix MSI and MSI-X IRQ setup, rollback, vector addressing, and affinity
selection.
Add the Raspberry Pi PCI vendor ID for RP1 and other downstream devices.

* [dm][dma] update DMA interface
Extend DMA mapping to honor OFW dma-ranges even
when no reserved memory pool is present,
and add PCI host-bridge DMA-region translation for PCI devices.
Prefer 32-bit-addressable allocations for translated devices,
improve pool allocation fallbacks and synchronization,
and establish a linear mapping for installed DMA pools when possible.

* [dm][dma] fixup PL330 work flow
Fix PL330 channel allocation so device-tree cells
select peripheral request lines rather than execution channels.
Generate proper peripheral DMA microcode using DMAWFP, DMALDP, DMASTP, and DMAFLUSHP,
encode burst lengths correctly,
honor transfer direction and non-secure attributes,
and allocate microcode from DMA-coherent memory.

* [DM/Input] Add ADC joystick, keyboard, and touchscreen drivers
Add polling input drivers for ADC-connected joysticks and resistor-
ladder keys. Parse Linux-compatible device-tree bindings, acquire ADC
channels through the IIO framework, and report absolute-axis and key
events.
Add an SPI touchscreen driver for ADS7843, ADS7845, ADS7846, ADS7873,
TSC2046, and XPT2046-compatible controllers. Support pen interrupts,
coordinate and pressure reporting, sample filtering, regulator control,
power management, and common touchscreen properties.
Add an I2C touchscreen driver for Goodix GT9xx controllers with
multi-touch reporting, GPIO-based reset and address selection, interrupt
handling with polling fallback, regulator control, panel configuration,
and alternate-address recovery.
Adapt the drivers to the RT-Thread device model and input framework,
following the corresponding Linux input drivers and device-tree
bindings.

* [dm][clk] fixup the work flow of CLK
Add RT_CLK_F_SET_RATE_NO_REPARENT so clock providers can preserv
the currently selected parent during rate changes.
Round and re-read the effective clock rate after parent handling,
skip redundant gate toggles and hardware programming when
the target is already active, and fix error handling for parent-clock allocation failures.

because regulator operations may sleep.

keep an initial enable reference for always-on supplies,
prevent the last disable from turning them off,
and let fixed/GPIO providers report and control their actual hardware state.

rt_data_queue_pop() holds the data queue spinlock while updating the ring
state, then calls rt_data_queue_len(). The length function tries to acquire
the same non-recursive spinlock again, causing an SMP deadlock when a pop
leaves the queue non-empty.
Add a private _data_queue_len_nolock() helper for callers which already hold
the queue lock. Keep the public rt_data_queue_len() protected by one spinlock
acquisition.
This does not change the public API, ABI, queue state transitions, low-water
mark wakeups, or event callback behavior.
Tested on a four-core Spacemit K1 with cyclic HDMI playback and by building the
SMP QEMU Virt64 RISC-V BSP with generic audio, Intel HDA and VirtIO Sound.

Add rt_bus_probe_device() to retry driver matching for a registered
but unbound device. Use it when an OFW-created platform device
is requested again, while preserving native-bus ownership
for I2C, SPI, and other non-platform devices.
Also instantiate eligible child platform devices after a parent node is registered.

sys_select() passed the raw user-space timeout pointer straight
through to select(), unlike readfds/writefds/exceptfds which are
all validated with lwp_user_accessable() and copied into kernel
memory first. A malicious or buggy user thread could pass a
timeout pointing at unmapped or otherwise invalid memory, which
select() would then dereference directly (timeout->tv_sec /
timeout->tv_usec) without any check, from kernel context.
Validate and copy it into a kernel-local struct timeval the same
way the fd_set arguments already are, before it reaches select().

Fill the mDNS domain name buffers with their array size instead of the size of the MDNS_DOMAIN_MAXLEN constant. This preserves the test intent of leaving different trailing bytes after equal names are encoded.

The RT_USING_CPU_USAGE_TRACER print block was duplicated identically in
both the ARCH_CPU_STACK_GROWS_UPWARD and the normal branch of
list_thread(). Both branches only differ in the stack usage line (which
has no trailing newline), so move the single shared block after the
#endif of the stack-growth conditional. No functional change.
rt_pci_ep_set_msi() checked the set_msix callback before calling set_msi. That rejects endpoint controllers that implement MSI without MSI-X, and can call through a NULL set_msi pointer when only MSI-X is provided.
The same helper converts a requested MSI vector count into the log2 field passed to the controller. Stop after the first value large enough for the request so smaller requests are not widened by later loop iterations.
