Subject: [RFC 11/13] soc: ti: pruss: Add helper functions to get/set PRUSS_CFG_GPMUX
Date: Wed, 6 Apr 2022 15:13:56 +0530	[thread overview]
Message-ID: <20220406094358.7895-12-p-mohan@ti.com> (raw)
In-Reply-To: <20220406094358.7895-1-p-mohan@ti.com>

From: Tero Kristo <t-kristo@ti.com>

Add two new helper functions pruss_cfg_get_gpmux() & pruss_cfg_set_gpmux()
to get and set the GP MUX mode for programming the PRUSS internal wrapper
mux functionality as needed by usecases.
