Subject: [PATCH v7 04/10] pwm: dwc: move memory alloc to own function
Date: Fri, 23 Dec 2022 15:38:14 +0000 [thread overview]
Message-ID: <20221223153820.404565-5-ben.dooks@sifive.com> (raw)
In-Reply-To: <20221223153820.404565-1-ben.dooks@sifive.com>
In preparation for adding other bus support, move the allocation
of the pwm struct out of the main driver code.
