Subject: [PATCH 2/3] interconnect: imx: Add imx_icc_get_bw and imx_icc_aggregate functions
Date: Sat, 1 Jan 2022 17:52:44 +0200 [thread overview]
Message-ID: <20220101155245.3139667-2-abel.vesa@nxp.com> (raw)
In-Reply-To: <20220101155245.3139667-1-abel.vesa@nxp.com>
The aggregate function will return whatever is the highest
rate for that specific node. The imx_icc_get_bw sets the
initial avg and peak to 0 in order to avoid setting them to
INT_MAX by the interconnect core.
