From: Geert Uytterhoeven Date: Mon, 10 May 2021 12:18:35 +0000 (+0200) Subject: dt-bindings: timer: renesas,tpu: Convert to json-schema X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d1dd216738f54c7a29a608c33ac98ce1f41e8fda;p=linux.git dt-bindings: timer: renesas,tpu: Convert to json-schema Convert the Renesas H8/300 Timer Pulse Unit Device Tree binding documentation to json-schema. Correct clock-names, as "peripheral_clk" is the name of the supplier, and all users use "fck". Note that there are two different bindings for the TPU, both using "renesas,tpu": this one for using the TPU as a clock source (used on H8/300), and a second use for using the TPU as a PWM controller (used on ARM). To avoid conflicts, both bindings are marked with the appropriate "select" logic, to check for the absence respectively presence of the "#pwm-cells" property.
