Hi All,
Gentle ping.
Are we happy with this patch series? Please let me know.
Regards,

> Subject: [PATCH v5 0/2] Add WDT driver for RZ/G2L
>
> This patch series aims to add WDT driver support for RZ/G2L SoC's.
>
> WDT has 3 channels
> 1) CH0 to check the operation of Cortex-A55-CPU Core0
> 2) CH1 to check the operation of Cortex-A55-CPU Core1
> 3) CH2 to check the operation of Cortex-M33 CPU
>
> WDT IP supports
> 1) Normal Watchdog Timer Function
> 2) Reset Request Function due to CPU Parity Error
>
> Once the software activates the watchdog timer, the watchdog timer does
> not stop until it is reset.
>
> Current driver supports Normal Watchdog Timer basic functionality.
>
> Tested WDT driver with selftests tool and reboot command
>
> All 3 channels tested with below command.

> v4->v5:
> * Started using the macros MICRO and USEC_PER_SEC
> * Renamed rzg2l_wdt_get_cycle_msec() to rzg2l_wdt_get_cycle_usec()
> * Fixed the value of priv->wdev.max_timeout in seconds.
> V3->V4:
> * Fixed the build issue reported by kernel test robot
> V2->V3:
> * Added Rb tag from Guenter Roeck
> * Removed Removed patch#1, as the clock changes related to WDT reset
> selection
> will be handled in TF-A.
> V1->V2:
> * started using clk_get/put instead of devm_clk_get/put
> * Moved devm_add_action_or_reset after set_drvdata() and
> * removed redundant action on devm_add_action_or_reset() failure.
> RFC->V1
> * Removed patch#3, the clk patch is queued for 5.17
> * Added clock-names and interrupt-names as required properties for RZ/G2L
> * Re-order clocknames with internal module clock first
> * Removed pclk_rate from priv.
> * rzg2l_wdt_write() returns void and Removed tiemout related to register
> update
> * rzg2l_wdt_init_timeout() returns void and removed delays.
> * removed set_bit(WDOG_HW_RUNNING,..) as we can stop watchdog
> * renamed reset_assert_clock_disable->reset_assert_pm_disable_put
> * started using devm_reset_control_get_exclusive()
> * removed platform_set_drvdata(pdev, priv) as there is no user
> * removed watchdog_set_restart_priority(&priv->wdev, 0) as 0 is the
> default.
> * removed remove callback as it is empty.
