From 91a577e77fdf55bdc6cd863581658761908c1686 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Thu, 26 Mar 2020 14:30:08 +0900 Subject: dt-bindings: clock: renesas: rcar-usb2-clock-sel: Add r8a77961 support This patch adds support for r8a77961 (R-Car M3-W+). To avoid confusion between R-Car M3-W (R8A77960) and R-Car M3-W+ (R8A77961), this patch also updates the comment of "renesas,r8a7796-rcar-usb2-clock-sel".

This is done by a set of dividers embedded into the CCU. A first block of dividers is used to create reference clocks for AXI-bus of high-speed peripheral IP-cores of the chip. The second block dividers alter the PLLs output signals to be then consumed by SoC peripheral devices. Both block DT nodes are ordinary clock-providers with standard set of properties supported. But in addition to that each clock provider can be used to reset the corresponding clock domain. This makes the AXI-bus and System Devices CCU DT nodes to be also reset-providers.

The transformation is done + by means of an embedded into CCU PLLs and gateable/non-gateable dividers. The + later ones are described in this binding. Each clock domain can be also + individually reset by using the domain clocks divider configuration + registers.

Depending on the consumer IP-core + peculiarities the dividers may lack of some functionality depicted on the + figure above (like EN, CLKDIV/LOCK/SETCLK).
