[PATCH v2 0/9] watchdog: msc313e: Fix issues Sashiko reported

[Tzung-Bi Shih]

The series mainly fixes issues reported by Sashiko in [1][2][3].

Patch 1 fixes a report in [1]:
- "[High] Missing platform_set_drvdata() or dev_set_drvdata() in the
  probe function leads to a guaranteed NULL pointer dereference during
  suspend/resume operations."

Patch 2 fixes reports in both [2][3]:
- "[High] Potential division by zero during `max_timeout` calculation."
- "[High] Potential division by zero if clk_get_rate() returns 0."

Patch 3 fixes reports in both [2][3]:
- "Clock reference count leak and unintended hardware activation in
  `msc313e_wdt_settimeout`."
- "[High] Repeatedly setting the watchdog timeout leaks clock prepare
  and enable references, potentially leading to refcount overflow."

Patch 4 fixes a report in [1]:
- "[High] The driver accesses hardware registers without ensuring the
  required clock is enabled, which can lead to a synchronous bus fault."
It also fixes a further report in [3]:
- "[Medium] Clock reference count is leaked on the probe error path if
  watchdog registration fails."

Patch 5 fixes reports in both [2][3]:
- "[High] Hardware watchdog is not properly stopped during system
  suspend if it was started by the bootloader but not opened by
  userspace."
- "[High] System will unexpectedly reset during suspend if the hardware
  watchdog is running but was never opened by userspace."

Patch 6 fixes an undefined behavior while I was reviewing the code.

Patch 7 fixes a report from a local AI tool.  If WDT was running at
boot, the timeout value could be inconsistent with what the driver has.
Sync the value.

Patch 8 fixes a report in [2]:
- "[High] The resume callback ignores the return value of
  msc313e_wdt_start()."

Patch 9 fixes a report in [2]:
- "[Low] Struct initialization uses commas instead of semicolons."

[PATCH v2 1/9] watchdog: msc313e: Fix NULL pointer dereference in PM callbacks

[Tzung-Bi Shih]

msc313e_wdt_probe() doesn't set the driver data for the platform device.
As a result, dev_get_drvdata() in msc313e_wdt_suspend() and
msc313e_wdt_resume() will return NULL, leading to a NULL pointer
dereference afterward.

Set the platform device driver data in msc313e_wdt_probe().

Simply browsed code under drivers/watchdog/, the following drivers also
use clk_get_rate() as a denominator directly:
- drivers/watchdog/digicolor_wdt.c
- drivers/watchdog/rtd119x_wdt.c
- drivers/watchdog/rzv2h_wdt.c

Let me know if you think we should fix them as well.

[PATCH v2 3/9] watchdog: msc313e: Fix clock leak and spurious timer in settimeout()

[Tzung-Bi Shih]

msc313e_wdt_settimeout() unconditionally calls msc313e_wdt_start() which
introduces two severe bugs:

1. If the watchdog is already active, calling start() again will
   increase the reference count of the clock again.  However stop() is
   only called once, the reference count is unbalance.
2. If the watchdog is stopped, calling settimeout() will start
   the hardware timer accidentally.

Factor out the register-writing logic into a helper function.  Only call
it in settimeout() if the watchdog is running.  Otherwise, simply update
`wdev->timeout`.

[PATCH v2 4/9] watchdog: msc313e: Enable clock before accessing hardware registers

[Tzung-Bi Shih]

msc313e_wdt_probe() reads from hardware registers without ensuring the
required clock is enabled.  Furthermore, if the bootloader leaves the
watchdog running, msc313e_wdt_probe() sets WDOG_HW_RUNNING without
increasing the clock's reference count.

While the clock is currently supplied as a fixed clock by the device
tree (`xtal_div2` in arch/arm/boot/dts/sigmastar/mstar-v7.dtsi) which
masks the physical issue, this still violates the API usage.

Call clk_prepare_enable() before reading WDT registers.  If the WDT is
running, leave the clock enabled so the CCF reference counter is
balanced.

[PATCH v2 5/9] watchdog: msc313e: Fix spurious reset on suspend

[Tzung-Bi Shih]

If the hardware watchdog was started by the bootloader and the device is
suspended before userspace opens it, the ping worker (from watchdog
core) is frozen and the active hardware timer continues running.  This
leads to a spurious system reset.

Check both watchdog_active() and watchdog_hw_running() when deciding
whether to start or stop the watchdog during suspend and resume.

Additionally, call watchdog_stop_ping_on_suspend() to ensure the ping
worker be correctly paused and restarted during suspend and resume.

[Tzung-Bi Shih]

If msc313e_wdt_start() fails during system resume, the error is
currently ignored.  Consequently, the watchdog isn't running without the
