From: Anatolij Gustschin Date: Wed, 14 Jun 2017 15:36:34 +0000 (-0500) Subject: fpga: Add flag to indicate bitstream needs decompression X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b37fa56069ce61d97a77dadca8dd65e522db3387;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git fpga: Add flag to indicate bitstream needs decompression Add a flag that is passed to the write_init() callback, indicating that the bitstream is compressed. The low-level driver will deal with the flag, or return an error, if compressed bitstreams are not supported.
