Subject: [PATCH v16 01/14] counter: stm32-lptimer-cnt: Provide defines for clock polarities
Date: Fri, 27 Aug 2021 12:47:45 +0900	[thread overview]
Message-ID: <a111c8905c467805ca530728f88189b59430f27e.1630031207.git.vilhelm.gray@gmail.com> (raw)
In-Reply-To: <cover.1630031207.git.vilhelm.gray@gmail.com>

The STM32 low-power timer permits configuration of the clock polarity
via the LPTIMX_CFGR register CKPOL bits. This patch provides
preprocessor defines for the supported clock polarities.
