The Orange Pi 5 Pro uses the same SoC and base as the Orange Pi 5 and
Orange Pi 5B but has had sound, USB, and leds wired up differently. The
5 and 5B boards use gmac for ethernet where the Pro has a PCIe attached
NIC.
Move the 5/5B-specific bits (analog-sound/es8388, FUSB302 Type-C,
gmac1, pwm-leds, i2s1_8ch routing, USB role-switch plumbing) out of
rk3588s-orangepi-5.dtsi into a new rk3588s-orangepi-5-5b.dtsi that is
included by both 5 and 5B.
The RK806 PLDO1 and PLDO2 outputs are wired differently between the
5/5B and the Pro (PLDO1/PLDO2 are swapped), so label the PMIC node
rk806 in the base dtsi, drop pldo-reg1/pldo-reg2 from it, and define
them via a &rk806 regulators augmentation in rk3588s-orangepi-5-5b.dtsi.
The Pro will supply its own mapping.

rk3588s-orangepi-5
The Orange Pi 5, 5B and 5 Pro schematics label the RK806 PLDO outputs
using the pattern VCC_*_S0 / VCCA_*_S0 / VDDA_*_S0. Rename the base
dtsi regulator labels (and the es8388 supply references) to match:
pldo-reg1: avcc_1v8_s0 -> vcc_1v8_s0
pldo-reg2: vcc_1v8_s0 -> vcca_1v8_s0
pldo-reg3: avdd_1v2_s0 -> vdda_1v2_s0
pldo-reg4: vcc_3v3_s0 -> vcca_3v3_s0
Also update the saradc vref-supply reference to track the pldo-reg1
rename. No functional change.

This reverts commit 096bd8c679185f898cae9933c6a68650fa26ea4f.
Just as with the Pinebook Pro, there are multiple chipset variants for
the Pinephone Pro, and multiple firmware binaries for different
distributions. The change causes issues with some of these combinations,
and reverting it resolves the issues. See the Closes below for the full
report.
Similarly with the Pinebook Pro adjustment, the original commit only
indicates "further description" and not indicative of fixing any
existing issues, so reverting should not kick any back up.

The YY3588 declares the HDMI-RX signal detect on GPIO1_C6, but the
receiver never sees an attached source there and cannot capture any
input.
That value was copied from the vendor device tree and is wrong. The
core-board schematics are not available and the SoM documentation does
not clearly show where this signal is routed, so the correct pin was
read from the device tree in the board's Android image: GPIO1_D5. With
GPIO1_D5 the receiver detects a connected source and locks, and v4l2
reports the input timing (1920x1080p60).

The USB3 OTG controller on the ROC-PC can be used in device mode,
but the board description only enabled the DWC3 controller and USB2 PHY.
The USBDP PHY remained disabled and the controller had no role-switch
default, so DWC3 did not register a UDC and USB gadget drivers such
as g_mass_storage failed to bind.
Enable the USBDP PHY and describe the controller as a USB role switch
with peripheral as the default role. This lets the controller register
as a UDC when no external role provider has selected a host role.
Tested on a Firefly Station M3 by binding g_mass_storage to expose the
eMMC as a USB mass-storage gadget.

The rk3588s-roc-pc ES8388 codec is connected to the i2s0_8ch audio
interface. Use the matching I2S0 MCLK output for the codec clock
instead of I2S1.
Using the I2S1 MCLK can leave the ALSA PCM running while the codec has
no usable master clock for the active audio path, resulting in silent
headphone output.
Also make the CPU DAI provide bitclock and frame clock. This matches
the active Rockchip I2S controller side and avoids relying on the codec
to drive the bus clocks.
Route the headphone output to LOUT2 and ROUT2, matching the old 5.10
BSP device tree. LOUT1 and ROUT1 are used for the speaker route there,
so using them for the headphone widget can leave the headphone jack
silent even while the ALSA path is active.
The old BSP also used hp-con-gpio on GPIO1_A4. Model that GPIO as a
simple audio amplifier so DAPM enables the headphone connection when the
headphone path is active.

The recently changes for 9Tripod X3568 mistakenly configured
the WiFi host-wake interrupt trigger type as IRQ_TYPE_LEVEL_LOW.
However, the associated pin `wifi_host_wake_irq` is configured
with an internal pull-down resistor.
When the WiFi module enters a low-power sleep state and leaves
the pin floating, this pull-down bias drives the pin low.
Since the interrupt is incorrectly set to level-low, this combination
traps the kernel in an endless interrupt loop.
Correct the interrupt trigger type to IRQ_TYPE_LEVEL_HIGH based on the
actual hardware logic: the pin is kept low by default and driven high by
the WiFi module to wake up the host.

According to the Jedec 5.1 specification, the device is held in reset
when RST_n is low, therefore the polarity of the line must be that, as

Due to the wrong polarity, eMMC devices with RST_n_FUNCTION[162]
bitfield [1:0] set to 0x1 (the default is 0x0) will be held in reset

Three fixed-regulator names on the NanoPC-T6 don't match the board
schematic [1].
- vcc3v3_pcie2x1l0 -> vdd_mpcie_3v3
This GPIO-switched 3v3 regulator is labeled vcc3v3_pcie2x1l0, but
it is wired to and consumed by &pcie2x1l1. Per the schematic,
the GPIO PCIE_M2_1_PWREN controls the power net VDD_MPCIE_3.3V;
rename to match.
- vdd_2v0_pldo_s3 -> vcc_2v0_pldo_s3
Typo in the regulator-name property of RK806-1 DCDC reg7. The node
label and the schematic power-net name both already use the vcc_
form; only the regulator-name string had vdd_.
- vcc3v3_pcie30 -> vcc3v3_pcie_m2_0
The GPIO-switched 3v3 feeding the M.2 M-Key (NVMe) slot is named
after the PCIe controller it sits behind rather than the schematic
power net. The schematic names it VCC3V3_PCIE_M2_0 (produced by an
MP2143-based buck off VCC_5V0, enabled by PCIE_M2_0_PWREN); rename
to match.

The AMD Geode platform that this is based on is now marked as
'Orphaned' in Kconfig, and it is likely that there are no XO1
users on modern kernels, but so far there is no consensus on
removing it entirely.
Select CONFIG_GPIOLIB_LEGACY for this platform and make sure the
sound driver portion cannot be compiled without this.

Most users of gpio-keys and gpio-keys-polled use modern gpiolib
interfaces, but there are still number of ancient sh, arm32 and x86
machines that have never been converted.
Add an #ifdef block for the parts of the driver that are only used on
those legacy machines.

cxl: Deny Features commands on the RAW mailbox path
|
|
This driver converts information from ACPI in x86 based tablets and
laptops into platform_data for the gpio_keys driver, using the obsolete
gpio number based interfaces.
This should really be converted to some other method, but since the
conversion is nontrivial, have this one select GPIOLIB_LEGACY for the
time being.
This enables turning GPIOLIB_LEGACY off by default on most kernel
builds. Since the driver is only used on x86 portables, add a CONFIG_X86
dependency, which means non-x86 allmodconfig builds usuallly build
without the legacy gpio support.

trace_user_fault_read() samples nr_context_switches_cpu() before enabling
preemption and retries the user copy if the counter changes. The helper
returns unsigned long long because rq->nr_switches is u64, but the saved
value is unsigned int.
Once a CPU has performed 2^32 context switches, assigning the counter to
cnt discards its upper bits. The comparison after the copy promotes cnt
back to unsigned long long, but the lost bits remain zero, so it reports a
change even when the task was never scheduled out. Every retry then fails
the same way until the 100-try guard warns and the user copy is abandoned.
This affects long-running systems and workloads with high context-switch
rates. A CPU switching 1,000 times per second takes about 50 days.
Store the sampled count in unsigned long long so the full value is
preserved.

When running instance tests, 'ftracetest' creates a new ftrace instance
and runs the tests inside it. Before starting each test, it executes
'initialize_system()' to reset the ftrace state to initial-state.
However, since 'initialize_system()' is executed in the context of the
instance directory, it only cleans up triggers and filters of that
instance.
Any triggers or dynamic events left behind in the top-level instance by
previous failed top-level tests, are left completely untouched. These
top-level leftovers can cause subsequent instance-based tests to fail
or even crash the kernel.
Fix this by executing 'initialize_system()' in the top-level tracing
directory once before entering the instance loop.

In 'struct trace_event_call', the 'module' pointer and the 'refcnt'
atomic variable share the same memory space in a union. For dynamic
events, the union member is 'refcnt', which acts as an active
reference counter.
When a dynamic event (such as kprobe, uprobe, fprobe, eprobe, or
wprobe) has a non-zero reference count (e.g. due to active event
triggers or perf attachments), its 'call->module' evaluates to a
small non-zero integer instead of NULL.
When filtering or setting events for a specific module (e.g., writing
':mod:<module>' to 'set_event'), the code in
'__ftrace_set_clr_event_nolock()' and 'update_event_fields()' reads
'call->module' directly without checking whether the event is dynamic.
This causes the kernel to treat the small integer (refcnt) as a
'struct module' pointer, leading to a NULL/invalid pointer dereference
(Oops) when dereferencing the module name.
Fix this by ensuring that the 'TRACE_EVENT_FL_DYNAMIC' flag is checked
before treating 'call->module' as a valid pointer in these code paths.

If the mmio_pipe_open() fails to find a PCI device, the hiter->dev
will be assigned to NULL. The mmiotrace read() function dereferences the
hiter->dev if hiter exists.

the hiter->dev before dereferencing it.

CXL Features commands where access control is provided depends on
what the CEL indicates.
Add the Features commands to cxl_disabled_raw_commands[] to ensure
that all Features commands are only accessible through the FWCTL
interface.
The cxl_raw_allow_all debugfs override knob bypasses the disabled list
if the user is aware of the risks and wants to use the RAW path for
