2020-08-19fpga: stratix10-soc: make FPGA task un-interruptibleRichard Gong1-20/+3
When CTRL+C occurs during the process of FPGA reconfiguration, the FPGA reconfiguration process stops and the user can't perform a new FPGA reconfiguration properly. Set FPGA task to be not interruptible so that the user can properly perform FPGA reconfiguration after CTRL+C event.

git://git.kernel.org/pub/scm/linux/kernel/git/mdf/linux-fpga into char-misc-next Moritz writes: FPGA Manager changes for 5.8 Here's the first set of changes for the 5.8-rc1 merge window. Dominic's change adds support for accessing AFU regions with gdb. Gustavo's change is a cleanup patch regarding variable lenght arrays. Richard's changes update dt-bindings and add support for stratix and agilex. Sergiu's changes update spi transfers with the new delay field. Xu's change addresses an issue with a wrong return value. Shubhrajyoti's change makes the Zynq FPGA driver return -EPROBE_DEFER on check of devm_clk_get failure. Xu's change for DFL enables multiple opens. All of these patches have been reviewed, have appropriate Acked-by's and have been in the last few linux-next releases without issues.

2020-04-29fpga: stratix10-soc: add compatible property value for intel agilexRichard Gong1-1/+2
Add compatible property value so we can reuse FPGA manager driver on Intel Agilex SoC platform. Signed-off-by: Richard Gong <[email protected]> Signed-off-by: Moritz Fischer <[email protected]>
2020-04-28firmware: fpga: replace the error codes with the standard onesRichard Gong1-15/+10
The Intel service layer driver has defined error codes for the specific services, which started from FPGA configuration then RSU (Remote Status Update). Intel service layer driver should define the standard error codes rather than keep adding more error codes for the new services. The standard error codes will be used by all the clients of Intel service layer driver. Replace FPGA and RSU specific error codes with Intel service layer’s Common error codes.

2019-05-24fpga: stratix10-soc: fix use-after-free on s10_init()Wen Yang1-1/+5
The refcount of fw_np has already been decreased by of_find_matching_node() so it shouldn't be used anymore. This patch adds an of_node_get() before of_find_matching_node() to avoid the use-after-free problem.

2019-01-31fpga: stratix10-soc: fix wrong of_node_put() in init functionNicolas Saenz Julienne1-4/+1
After finding a "firmware" dt node stratix10 tries to match it's compatible string with it. To do so it's calling of_find_matching_node() which already takes care of decreasing the refcount on the "firmware" node. We are then incorrectly decreasing the refcount on that node again. This patch removes the unwarranted call to of_node_put().

2018-11-26fpga: add intel stratix10 soc fpga manager driverAlan Tull1-0/+535
Add driver for reconfiguring Intel Stratix10 SoC FPGA devices. This driver communicates through the Intel service layer driver which does communication with privileged hardware (that does the FPGA programming) through a secure mailbox.
