Subject: [PATCH v3 06/11] firmware: ti_sci: rm: Remove ring_get_config support
Date: Mon, 12 Oct 2020 14:51:14 +0300 [thread overview]
Message-ID: <20201012115119.11333-7-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20201012115119.11333-1-peter.ujfalusi@ti.com>
The ring_get_cfg (0x1111 message) is not used and it is not supported by
sysfw for a long time.
