From: Steve Twiss <stwiss.opensource@xxxxxxxxxxx> The of_device_id match array is added to support "dlg,da9062-watchdog" as a valid .compatible string. A MODULE_DEVICE_TABLE() macro is added. This patch assumes the use of a DA9062 fallback compatible string for the DTS to pick up the DA9062 device driver for use with the DA9061 watchdog hardware Copyright header is updated to add DA9061 in its description and the module description macro is extended to include DA9061. Kconfig is updated to reflect support for DA9061/62. Signed-off-by: Steve Twiss <stwiss.opensource@xxxxxxxxxxx>

--- This patch applies against linux-next and v4.8 v2 -> v3 - Patch renamed from [PATCH V2 08/10] to [PATCH V3 7/9] - Removal of match->data and of_match_node search. There is only one compatible string now. and delete the .data = &da9062_watchdog_info association in the struct of_device_id compatible table. - Addition of MODULE_DEVICE_TABLE macro to allow modinfo additions: da9062_wdt.ko platform:da9062_watchdog of:N*T*Cdlg,da9062_watchdogC* of:N*T*Cdlg,da9062_watchdog v1 -> v2 - Patch renamed from [PATCH V1 04/10] to [PATCH V2 08/10] -- these changes were made to fix checkpatch warnings caused by the patch set dependency order - Removal of the DA9061 compatible entries for this device driver. - Additional explanation in the patch description for the use of a fall-back compatible DTS string Guenter, Alterations have been made in accordance with the previous e-mail thread on the use of compatible strings: https://lkml.org/lkml/2016/10/7/641 This patch now assumes the use of a fallback compatible string in the DTS.
