-Device Tree Clock bindings for the Zynq Ultrascale+ MPSoC controlled using
-Zynq MPSoC firmware interface
---------------------------------------------------------------------------
-The clock controller is a h/w block of Zynq Ultrascale+ MPSoC clock
-tree. It reads required input clock frequencies from the devicetree and acts
-as clock provider for all clock consumers of PS clocks.
-
-See clock_bindings.txt for more information on the generic clock bindings.
-
-Required properties:
- - #clock-cells: Must be 1
- - compatible: Must contain: "xlnx,zynqmp-clk"
- - clocks: List of clock specifiers which are external input
- clocks to the given clock controller. Please refer
- the next section to find the input clocks for a
- given controller.
- - clock-names: List of clock names which are exteral input clocks
- to the given clock controller. Please refer to the
- clock bindings for more details.
-
-Input clocks for zynqmp Ultrascale+ clock controller:
-
-The Zynq UltraScale+ MPSoC has one primary and four alternative reference clock
-inputs. These required clock inputs are:
- - pss_ref_clk (PS reference clock)
- - video_clk (reference clock for video system )
- - pss_alt_ref_clk (alternative PS reference clock)
- - aux_ref_clk
- - gt_crx_ref_clk (transceiver reference clock)
-
-The following strings are optional parameters to the 'clock-names' property in
-order to provide an optional (E)MIO clock source:
- - swdt0_ext_clk
- - swdt1_ext_clk
- - gem0_emio_clk
- - gem1_emio_clk
- - gem2_emio_clk
- - gem3_emio_clk
- - mio_clk_XX # with XX = 00..77
- - mio_clk_50_or_51 #for the mux clock to gem tsu from 50 or 51
-
-
-Output clocks are registered based on clock information received
-from firmware. Output clocks indexes are mentioned in
-include/dt-bindings/clock/xlnx-zynqmp-clk.h.
