fpga: ice40-spi: Add SPI device ID table

2021-09-27T21:00:41+00:00

Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding a SPI ID table.

fpga: dfl: Avoid reads to AFU CSRs during enumeration

2021-09-16T22:20:55+00:00

CSR address space for Accelerator Functional Units (AFU) is not available during the early Device Feature List (DFL) enumeration. Early access to this space results in invalid data and port errors. This change adds a condition to prevent an early read from the AFU CSR space.

fpga: machxo2-spi: Fix missing error code in machxo2_write_complete()

2021-09-15T21:01:24+00:00

The error code is missing in this code scenario, add the error code '-EINVAL' to the return value 'ret'. Eliminate the follow smatch warning: drivers/fpga/machxo2-spi.c:341 machxo2_write_complete() warn: missing error code 'ret'.

fpga: machxo2-spi: Return an error on failure

2021-09-15T21:01:17+00:00

Earlier successes leave 'ret' in a non error state, so these errors are not reported. Set ret to -EINVAL before going to the error handler. This addresses two issues reported by smatch: drivers/fpga/machxo2-spi.c:229 machxo2_write_init() warn: missing error code 'ret' drivers/fpga/machxo2-spi.c:316 machxo2_write_complete() warn: missing error code 'ret' [mdf@kernel.org: Reworded commit message] Fixes: 88fb3a002330 ("fpga: lattice machxo2: Add Lattice MachXO2 support") Reported-by: Dan Carpenter Signed-off-by: Tom Rix Signed-off-by: Moritz Fischer

fpga: dfl: expose feature revision from struct dfl_device

2021-07-29T19:54:10+00:00

DFL device drivers have a common need for checking feature revision information from the DFL header, as well as other common DFL information like the already exposed feature id and type. This patch exposes the feature revision information directly via the DFL device data structure. Since the DFL core code has already read the DFL header, this this patch saves additional mmio reads from DFL device drivers too.
