From bdc585f987a0e18be9399abc609d564c83f74c2b Mon Sep 17 00:00:00 2001 From: Duje Mihanović Date: Sun, 7 Jan 2024 12:46:59 +0100 Subject: dt-bindings: pxa-pwm: Convert to YAML MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Convert the PXA PWM binding file from TXT to YAML. The original binding does not mention any clocks, but the PWM controller will not probe without a clock.
