Add support for the Xilinx XADC core used in Zynq 7000. References: - Zynq-7000 All Programmable SoC Technical Reference Manual - 7 Series FPGAs and Zynq-7000 All Programmable SoC XADC Dual 12-Bit 1 MSPS Analog-to-Digital Converter Tested with Linux using QEMU machine xilinx-zynq-a9 with devicetree files zynq-zc702.dtb and zynq-zc706.dtb, and kernel configuration multi_v7_defconfig. Reviewed-by: Alistair Francis <alistair.francis@xilinx.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> [ PC changes: * Changed macro names to match TRM where possible * Made programmers model macro scheme consistent * Dropped XADC_ZYNQ_ prefix on local macros * Fix ALM field width * Update threshold-comparison interrupts in _update_ints() * factored out DFIFO pushes into helper. Renamed to "push/pop" * Changed xadc_reg to 10 bits and added OOB check. * Reduced scope of MCTL reset to just stop channel coms. * Added dummy read data to write commands * Changed _ to - seperators in string names and filenames * Dropped ------------ in header comment * Catchall'ed _update_ints() in _write handler. * Minor whitespace changes. * Use ZYNQ_XADC_FIFO_DEPTH instead of ARRAY_SIZE() ] Signed-off-by: Peter Crosthwaite <crosthwaite.peter@gmail.com> Tested-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> |
