Subject[PATCH 2/2] dt-bindings: xilinx: Separate clock binding from firmware doc
Date
From: Rajan Vaja <rajan.vaja@xilinx.com>

Clock description is part of firmware doc. Move clock description
in separate doc.

+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.
