Subject: [PATCH v1 4/6] pwm: lpss: Allow other drivers to enable PWM LPSS
Date: Tue, 1 Nov 2022 17:56:40 +0200 [thread overview]
Message-ID: <20221101155642.52575-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20221101155642.52575-1-andriy.shevchenko@linux.intel.com>
The PWM LPSS device can be embedded in another device.
In order to enable it, allow that drivers to probe
a corresponding device.
