Subject: [PATCH v4 4/4] clk: vf610: Add support for the Ethernet switch clocks
Date: Thu, 29 Jan 2026 10:54:42 +0100 [thread overview]
Message-ID: <20260129095442.1646748-5-lukma@nabladev.com> (raw)
In-Reply-To: <20260129095442.1646748-1-lukma@nabladev.com>
The vf610 device has built in the MoreThanIP L2 switch. For proper
operation it is required to enable ESW and MAC table lookup
clocks.
The MAC table spans from 0x400E_C000 for 0x4000 and it is necessary
to provide clocks for each AIPS1-"slot", which size is 0x1000
(hence four separate entries).
Those can be enabled via clock gating CCM_CCGR10 register
(0x4006_B068).
