From c78a5bc2e77e8fc5be29cda5b28c9b9afd0f4b6d Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Sat, 1 May 2010 18:38:28 -0400 Subject: Davinci: watchdog reset separation across socs The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.
