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. I am re-sending the series with correct Signed-off-by headers. 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.
