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) Markus Mayer (2): watchdog: bcm281xx: Watchdog Driver ARM: bcm281xx: watchdog configuration arch/arm/configs/bcm_defconfig | 3 + drivers/watchdog/Kconfig | 22 +++ drivers/watchdog/Makefile | 1 + drivers/watchdog/bcm_kona_wdt.c | 367 +++++++++++++++++++++++++++++++++++++++ 4 files changed, 393 insertions(+) create mode 100644 drivers/watchdog/bcm_kona_wdt.c -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
