Date: Fri, 22 Jul 2022 17:16:08 +0300	[thread overview]
Message-ID: <20220722141614.297383-8-oleksandr.suvorov@foundries.io> (raw)
In-Reply-To: <20220722141614.297383-7-oleksandr.suvorov@foundries.io>

Add a "compatible" string to binary flag converter, which uses
a callback str2flag() of given FPGA driver if available.

Changes in v10:
- fix mixed types of return value;
