From 387ca5bf4fe2297c93869b6f639afa8d849fb877 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Mon, 12 Mar 2012 04:29:58 -0600 Subject: [PATCH] ARM: OMAP: hwmod: Use sysc_fields->srst_shift and get rid of hardcoded SYSC_TYPE2_SOFTRESET_MASK MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is useful when we have broken type2 compliant IPs' where the softreset shift is not the same as SYSC_TYPE2_SOFTRESET_SHIFT and hence is overridden using sysc_fields->srst_shift. We have at least one such instance now with onchip keypad on OMAP5 which has a different softreset shift as compared to other type2 IPs'.
