From: Chris Morgan <macromorgan@hotmail.com>

Add support for the Anbernic RG Vita-Pro, based on the Rockchip RK3576 SoC.

Changes Since V1:
 - Updated documentation filename to matche compatible string.
 - Corrected order of allocating IRQ in charger driver and switched
   to using devm managed function to allocate work queue.
Changes Since V2:
 - Corrected issue with naming of panel binding document and added
   fallback compatible string.
 - Switched to devm helpers in panel driver. Note that
   devm_drm_panel_add() is currently only in the drm-next branch.
 - Optimized setting GPIOs for panel driver.
Changes Since V3:
 - Fixed numerous issues identifed by Sashiko bot, mainly relating
   to unclamped or improperly clamped values from within the
   charger driver.
 - Corrected hard-coded values in the panel driver unprepare routine
   as well as correcting an improperly checked return condition.
Changes Since V4:
 - Fixed errors identified by Sashiko bot on charger driver that could
   result in an improper value being written to the registers.
 - Corrected some error handling in the panel driver.

Document the SG Micro sgm41542 battery charger/boost converter.
The parameters of input-current-limit-microamp and
input-voltage-limit-microvolt are defined as such since they are in
common use among multiple bindings currently.

Add support for the SG Micro SGM41542 charger/boost converter.
Driver was adapted from Rockchip BSP driver [1] and confirmed
with vendor datasheet [2].

From: Chris Morgan <macromorgan@hotmail.com>

Add device tree for the Anbernic RG Vita-Pro, based on the Rockchip
RK3576. All hardware is currently working except for the accelerometer,
the touchscreen, the battery monitor, and DisplayPort over USB-C. PWM
is also missing currently, and as a result the LEDs and panel backlight
are currently controlled via GPIO but will be changed to PWM once
supported.

The Anbernic RG Vita-Pro includes the following hardware:
 - A 1080x1920 DSI display with touch.
 - 21 buttons.
 - 2 Analog joysticks controlled via userspace.
 - 3 LEDs.
 - 64GB eMMC, 2 SDMMC slots.
 - RTL8852BE WiFi (with Bluetooth via UART)
 - 1 USB 3.0 USB-C port in OTG mode.
 - 3.5mm headphone jack with play button support.
 - 5000mAH battery

The following hardware has incomplete driver support and is not yet
working:
 - An Invensense icm42607p accelerometer.
 - A Cellwise cw221x battery monitor.
 - A Synaptics i2c touchscreen.
 - DisplayPort over USB-C alt-mode.
 - PWM controller.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] The driver calls an undefined function `devm_drm_panel_add()`, causing a compilation failure. Furthermore, the driver lacks a `.remove` callback (or a devres action) to call `drm_panel_remove()`. If the build error is fixed by trivially substituting the standard `drm_panel_add()`, it will result in a Use-After-Free vulnerability.

[Severity: High]
Does devm_drm_panel_add() exist in the kernel? It looks like this might
cause a build failure due to an undefined function.

If this is resolved by simply replacing it with drm_panel_add(), could it
result in a use-after-free on unbind? Because the panel is allocated with
devm_drm_panel_alloc() earlier, its memory will be automatically freed when
the device is unbound. If drm_panel_remove() is never called, the freed
panel would remain in the global DRM panel list, risking memory corruption
when other components traverse the list.

[Severity: High]
Would it make sense to add a .remove callback here to call
drm_panel_remove(), or perhaps register a custom devm action during probe,
to ensure the panel is properly unregistered from the subsystem on teardown?

Thank you for your contribution! Sashiko AI review found 9 potential issue(s) to consider:
- [High] Registration of power supply prior to initializing limits causes invalid sysfs clamping.
- [High] Missing cancellation of delayed watchdog work in the shutdown callback.
- [High] NULL pointer dereference when accessing `i2c_client_get_device_id()` result.
- [High] Optional battery info properties mistakenly initialized to -EINVAL causing undefined behavior.
- [Medium] Incorrect clamp ordering causes the charger voltage to exceed the configured safety maximum.
- [Medium] Bitmask macro used instead of integer time value for watchdog timer.
- [Medium] Unconditional calls to `disable_irq_wake()` trigger kernel warnings if IRQ wake was never enabled.
- [Medium] Incorrect return of `IRQ_NONE` after hardware interrupt has already been serviced.
- [Medium] Concurrent sysfs writes can desynchronize software and hardware watchdog states.

power: supply: sgm41542: Add SG Micro sgm41542 charger

[Severity: Medium]
Is there a risk of bypassing the max_vreg limit here? If a user requests
4.5V and the DT max_vreg limit is 4.336V, the first check evaluates to
false, skipping the gap clamp. The second clamp reduces the requested
voltage to 4.336V, producing reg_val = 15.

The hardware defines this as a special configuration for 4.352V, bypassing
the intended limit. Should max_vreg be enforced before applying
hardware-specific gap limits?

[Severity: Medium]
Could concurrent sysfs writes to the online property cause a desynchronization
here? 

Because there is no locking in this function, race conditions might leave
the hardware watchdog armed while the software state reads false. This could
prevent the delayed work from re-arming the watchdog, resulting in unintended
device resets.

[Severity: Medium]
Does this pass the correct value to the watchdog configuration? 

SGM4154X_WDT_TIMER_40S is a bitmask (BIT(4), which is 16). The 
sgm4154x_set_watchdog_timer() function expects an integer time value like
40 or 80. Passing 16 causes it to fall through to the else block, silently
configuring a 160s timeout instead.

[Severity: Medium]
Is it safe to return IRQ_NONE here?

Reading the state via sgm4154x_get_state() effectively clears the interrupt
on the hardware. If sgm4154x_set_input_curr_lim() subsequently fails,
returning IRQ_NONE will cause the kernel's spurious interrupt detector to
erroneously count the interrupt as unhandled, which might lead to the IRQ
line being permanently disabled.

[Severity: High]
Could this initialize the limits to negative values?

Optional battery parameters default to -EINVAL (-22) when not defined in
the device tree. Because -22 is truthy, this block will assign -22 to
max_vreg. When clamping chrg_volt later, it can produce a negative result
that gets bitwise left-shifted, triggering undefined behavior and corrupting
hardware registers. Should this verify that the values are non-negative?

[Severity: High]
Is there a risk of a NULL pointer dereference here?

If the driver is bound via sysfs or dynamically instantiated without an
explicit match in sgm4154x_i2c_ids, i2c_client_get_device_id() returns NULL,
leading to a crash on id->name.

[Severity: High]
Does registering the power supply before initializing the hardware limits
expose uninitialized sysfs attributes?

The sgm->init_data is zero-initialized at this point. If userspace writes to
a property like CONSTANT_CHARGE_VOLTAGE during this window, it will clamp
against a max_vreg of 0. Subtracting the minimum limit from 0 yields a
negative number that gets bitwise left-shifted, causing undefined behavior.

[Severity: Medium]
Can this trigger a WARN_ON if the irq was never provided? 

The enable_irq_wake() call earlier is guarded by checking if client->irq is
non-zero, but this disable_irq_wake() call is unconditional. If the device
probes without an IRQ, this will drop the wake depth below zero.

[Severity: High]
Does the shutdown sequence need to cancel the delayed work?

Since devres teardown is not called on shutdown, sgm_delay_work remains
active. If it fires after the I2C controller has suspended, it could attempt
transactions on an inactive bus, causing timeouts or hangs during system halt.

[Severity: Medium]
Similar to the probe error path, is it safe to unconditionally call
disable_irq_wake() here? If the device was instantiated without an IRQ, this
could trigger a WARN_ON in the IRQ core.

arm64: dts: rockchip: Add Anbernic RG Vita-Pro

This commit adds the device tree for the Anbernic RG Vita-Pro, based on the
Rockchip RK3576. It defines the hardware configuration including the display,
buttons, analog joysticks, battery, and USB-C.

[Severity: Medium]
The commit message lists "DisplayPort over USB-C alt-mode" for video output
but does not mention an HDMI port. Does this device physically have an HDMI
port, or is this a leftover ghost configuration?

Leaving the HDMI pipeline enabled might waste resources or cause audio/display
routing confusion in userspace if the port doesn't exist on the hardware.

[Severity: High]
Does advertising 3A for the source PDO risk overloading the SGM41542 charger?

The husb311 Type-C port advertises 5V at 3A to connected sinks, but its
vbus-supply is powered by the sgm41542 charger's OTG boost converter.
According to the sgm41542 driver, its maximum OTG output capability is
physically limited to 2A (2,000,000 uA).

If a sink attempts to draw the advertised 3A, could it cause an overcurrent
fault and collapse the VBUS rail?

[Severity: Medium]
The commit message notes the analog joysticks are "controlled via userspace,"
but the &spi1 node doesn't have a child device node (such as spidev).

Without a child node, the kernel SPI subsystem will not instantiate an SPI
device. How will userspace communicate with the joysticks if the device node
is missing?
