This is version 2 of the watchdog driver for the BCM281xx family of mobile SoCs.
Changes since version 1:
- Added module name to "help" section in Kconfig
- A few cosmetic code simplifications and fixes
- Removed most dev_info() calls and changed the remaining ones to dev_dbg()
- Renamed SECWDOG_WD_LOAD_FLAG_MASK to SECWDOG_WD_LOAD_FLAG
- Added some comments to secure_register_read() and struct bcm_kona_wdt
- Added delay to secure_register_read()
- Reduced maximum retry loop from 10000 to 1000
- Introduced "busy_count" variable to count how often secure_register_read()
gets stalled; this is available through debugfs
- Simplified secure_register_read() to return -ETIMEDOUT rather than using
a variable parameter to indicate a timeout error
- Got rid of all uses of -EAGAIN
- Fixed return value check for debugfs_create_dir()
- Simplified bcm_kona_wdt_debugfs_init() by getting rid of goto
- Created new generic function bcm_kona_wdt_ctrl_reg_modify()
- The following functions now use bcm_kona_wdt_ctrl_reg_modify():
- bcm_kona_wdt_set_resolution_reg()
- bcm_kona_wdt_set_timeout_reg()
- bcm_kona_wdt_stop()
- Made bcm_kona_wdt_set_timeout_reg() more generic, so bcm_kona_wdt_start()
can use it
- Removed MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
