Changelog v1 -> v2: * add common `include/linux/fpga/adi-axi-common.h` with reg version; more regs will be added * use macro to check version of HDL core from common header * add my S-o-B to patch `dmaengine: axi-dmac: Discover length alignment requirement` > include/linux/fpga/adi-axi-common.h | 19 +++++++++++++++++++ > 1 file changed, 19 insertions(+) > create mode 100644 include/linux/fpga/adi-axi-common.h > > diff --git a/include/linux/fpga/adi-axi-common.h b/include/linux/fpga/adi-axi-common.h > new file mode 100644 > index 000000000000..7966c89561b1 > --- /dev/null > +++ b/include/linux/fpga/adi-axi-common.h > @@ -0,0 +1,19 @@ > +// SPDX-License-Identifier: GPL-2.0 > +/* > + * Analog Devices AXI common registers & definitions > + * > + * Copyright 2019 Analog Devices Inc. > + * > + * https://wiki.analog.com/resources/fpga/docs/axi_ip > + * https://wiki.analog.com/resources/fpga/docs/hdl/regmap > + */ > + > +#ifndef ADI_AXI_COMMON_H_ > +#define ADI_AXI_COMMON_H_ > + > +#define ADI_AXI_REG_VERSION 0x0000 > + > +#define ADI_AXI_PCORE_VER(major, minor, patch) \ > + (((major) << 16) | ((minor) << 8) | (patch)) > + > +#endif /* ADI_AXI_COMMON_H_ */
