Subject: [RESEND PATCH next v2 4/6] ARM: dts: k2hk-netcp: add cpts refclk_mux node
Date: Fri, 5 Jul 2019 18:12:45 +0300 [thread overview]
Message-ID: <20190705151247.30422-5-grygorii.strashko@ti.com> (raw)
In-Reply-To: <20190705151247.30422-1-grygorii.strashko@ti.com>
KeyStone 66AK2H/K 1G Ethernet Switch Subsystems, can control an external
multiplexer that selects one of up to 32 clocks for time sync reference
(RFTCLK) clock. This feature can be configured through CPTS_RFTCLK_SEL
register (offset: x08) in CPTS module and modelled as multiplexer clock.
Hence, add cpts-refclk-mux clock node which allows to mux one of SYSCLK2,
SYSCLK3, TIMI0, TIMI1, TSREFCLK clocks as CPTS reference clock [1] and
group all CPTS properties under "cpts" subnode.
