Subject: [PATCH v6 0/2] watchdog: Add support for ImgTec PowerDown Controller Watchdog Timer
Date: Wed, 26 Nov 2014 14:56:32 +0530 [thread overview]
Message-ID: <1416993994-8456-1-git-send-email-Naidu.Tellapati@gmail.com> (raw)
This patchset provides support for the PowerDown Controller (PDC) Watchdog Timer
found on Pistachio SOC from Imagination Technologies (ImgTec).
The series is based on 3.18-rc5.
Changes from v5:
* Removed unused struct pdc_wdt_dev variables.
* Removed out_wdt label in probe function.
Changes from v4:
* Added warning message if initial timeout value exceeds maximum timeout.
Changes from v3:
* Removed PDC_WD_MAX_DELAY.
* Removed spinlock.
* Removed timeout check inside pdc_wdt_set_timeout function.
* Changed identity to IMG PDC Watchdog.
* Removed pdc_wdt_set_timeout call from the probe function.
* Removed pdc_wdt_shutdown function call from pdc_wdt_remove function
and added pdc_wdt_stop function call instead.
Changes from v2:
* Removed interrupt.h header file.
* Removed clock rate-change notifier callback.
Changes from v1:
* Arranged all include files in alphabetical order.
* Arranged register field masks/shifts defines next to their
corresponding register
* Registered clock rate-change notifier callback.
* Removed all references to 32 kHz fixed clock rate.
Now the clock rate is read dynamically using clk_get_rate().
* Defined a macro PDC_WD_CONFIG_ENABLE.
* Added code for getting system clock.
* Moved module_param stuffs next to the corresponding variable defines.
* Added code in the function pdc_wdt_remove for stopping watchdog.
* Removed MODULE_ALIAS.
* Removed few unwanted spaces and unwanted blank lines.
