From 0829c35dc5346e90f428de61896362b51ab58296 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Sat, 21 May 2022 13:02:03 +0200 Subject: pwm: Drop support for legacy drivers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There are no drivers left providing the legacy callbacks. So drop support for these. If this commit breaks your out-of-tree pwm driver, look at e.g. commit ec00cd5e63f0 ("pwm: renesas-tpu: Implement .apply() callback") for an example of the needed conversion for your driver.
