Subject: [PATCH v2 1/5] dt-bindings: clk: meson: add sm1 periph clock controller bindings
Date: Mon, 26 Aug 2019 09:25:35 +0200 [thread overview]
Message-ID: <20190826072539.27725-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190826072539.27725-1-narmstrong@baylibre.com>
Update the documentation to support clock driver for the Amlogic SM1 SoC
and expose the GP1, DSU and the CPU 1, 2 & 3 clocks.
SM1 clock tree is very close, the main differences are :
- each CPU core can achieve a different frequency, albeit a common PLL
- a similar tree as the clock tree has been added for the DynamIQ Shared Unit
- has a new GP1 PLL used for the DynamIQ Shared Unit
- SM1 has additional clocks like for CSI, NanoQ an other components
