From 6fd893c409e5939ea2145b27796c155535988734 Mon Sep 17 00:00:00 2001 From: Wu Hao Date: Sat, 30 Jun 2018 08:53:33 +0800 Subject: fpga: dfl: afu: add DFL_FPGA_GET_API_VERSION/CHECK_EXTENSION ioctls support DFL_FPGA_GET_API_VERSION and DFL_FPGA_CHECK_EXTENSION ioctls are common ones which need to be supported by all feature devices drivers including FME and AFU. This patch implements above 2 ioctls in FPGA Accelerated Function Unit (AFU) driver.
