Add MFD core driver support for DA9062
Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com>
---
Changes in V4:
- Removal of struct da9062 unrequired data from core.h and driver code
- Remove IRQ handler for VDD_WARN and corresponding IRQ request code
- Use DEFINE_RES_NAMED() macro for resource definitions
- Refactor da9062_clear_fault_log() to remove inconsistencies
- Refactor da9062_device_init() and da9062_irq_init() into probe()
- Add new function get_device_type() for variant and device_id information
- devm_kzalloc to alloc *chip instead of struct and use not-chip on error
- Move da9062_dt_ids closer to usage
- Move LUT definitions into da9062_regmap_config structure
- Erase da9062_device_exit() abstractions
- Clean up header inclusions through removal of redundant entries
- Whitespace and string literal discipline
Changes in V3:
- Removed references to the RTC and OnKey in the mfd_cell definition.
Changes in V2:
- Copyright headers GPL v2 (and later) match correct 'GPL' in MODULE_LICENSE
- Ensure DA9062 core is tristate in Kconfig so it can be built as a module
- Move VDD_WARN code and resource into the core instead of regulator driver
This patch applies against linux-next and v4.1-rc5

Add watchdog driver support for DA9062
Reviewed-by: Guenter Roeck <linux@roeck-us.net>
Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com>
---
Changes in V4:
- Added reviewed-by from Guenter Roeck
Changes in V3:
- Removed unnecessary return statement in da9062_apply_window_protection()
- Deleted dev_err() kernel noise in da9062_wdt_update_timeout_register()
- Changed dev_alert() to be a dev_err() in da9062_wdt_stop()
- Deleted the "watchdog ping" debug message in da9062_wdt_ping()
- Refactored the error path inthe probe() to remove redundant error gotos
- Altered dev_err() string to notify failures more specifically in probe()
- Removed the space in MODULE_ALIAS string "platform: da9062-watchdog"
- Ensure request for devm_request_threaded_irq() removal is completed
Changes in V2:
- Removed informational dev_info() 'installed watchdog' message
- Copyright headers GPL v2 (and later) match correct 'GPL' in MODULE_LICENSE
- Removed the explicit 300 msecs delay from the reset_watchdog_timer()
function and replaced it with a variable delay (depending on the
difference since the last ping). A debug message is used to catch the
multiple pings trying to break the 300 msecs protection barrier.
- Fix error paths for the functions da9062_wdt_update_timeout_register()
and da9062_wdt_stop()
- Add error paths in the probe() and correctly clean-up the registered
device if there is a problem after registration.
This patch applies against linux-next and v4.1-rc5
