Subject: [PATCH] bus: mhi: core: Use mhi_soc_reset() API instead of register write
Date: Thu, 1 Jul 2021 12:55:38 -0700 [thread overview]
Message-ID: <1625169338-32026-1-git-send-email-bbhatt@codeaurora.org> (raw)
Currently, register writes are used when ramdump collection in
panic path occurs. Replace that with new mhi_soc_reset() API such
that a controller defined reset() function is exercised if one is
present and the regular SOC reset is done if it is not.
