2017-04-26fpga: region: release FPGA region reference in error pathTobias Klauser1-1/+3
If fpga_region_get_manager() fails in fpga_region_program_fpga(), a reference to the fpga_manager instance previously acquired through fpga_region_get() is retained. Make sure to properly release it in the error case by using a separate jump label which will call fpga_region_put() in before returning.

2017-03-17fpga: region: Add fpga-region property 'encrypted-fpga-config'Moritz Fischer1-2/+6
Add fpga-region property to allow passing the fact that the bitstream is encrypted to the fpga-region and ultimately to the low-level driver.
