fpga: dfl: pci: fix return value of cci_pci_sriov_configure

2020-03-31T03:45:30Z

pci_driver.sriov_configure should return negative value on error and number of enabled VFs on success. But now the driver returns 0 on success. The sriov configure still works but will cause a warning message: XX VFs requested; only 0 enabled This patch changes the return value accordingly.

fpga: zynq: Remove clk_get error message for probe defer

2020-03-31T03:45:21Z

In probe, the driver checks for devm_clk_get return and print error message in the failing case. However for -EPROBE_DEFER this message is confusing so avoid it. The similar change was done also by commit 28910cee898c ("fpga: xilinx-pr-decoupler: Remove clk_get error message for probe defer") Signed-off-by: Shubhrajyoti Datta Signed-off-by: Michal Simek Signed-off-by: Moritz Fischer

fpga: dfl: fme: add power management support

2019-10-17T02:18:27Z

This patch adds support for power management private feature under FPGA Management Engine (FME). This private feature driver registers a hwmon for power (power1_input), thresholds information, e.g. (power1_max / crit / max_alarm / crit_alarm) and also read-only sysfs interfaces for other power management information. For configuration, user could write threshold values via above power1_max / crit sysfs interface under hwmon too.

fpga: dfl: fme: add thermal management support

2019-10-17T02:18:27Z

This patch adds support to thermal management private feature for DFL FPGA Management Engine (FME). This private feature driver registers a hwmon for thermal/temperature monitoring (hwmon temp1_input). If hardware automatic throttling is supported by this hardware, then driver also exposes sysfs interfaces under hwmon for thresholds (temp1_max/ crit/ emergency), threshold alarms (temp1_max_alarm/ temp1_crit_alarm) and throttling policy (temp1_max_policy).

fpga: Remove dev_err() usage after platform_get_irq()

2019-10-05T01:57:16Z

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

Merge tag 'char-misc-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2019-09-18T18:14:31Z

Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver pull request for 5.4-rc1. As has been happening in previous releases, more and more individual driver subsystem trees are ending up in here. Now if that is good or bad I can't tell, but hopefully it makes your life easier as it's more of an aggregation of trees together to one merge point for you. Anyway, lots of stuff in here: - habanalabs driver updates - thunderbolt driver updates - misc driver updates - coresight and intel_th hwtracing driver updates - fpga driver updates - extcon driver updates - some dma driver updates - char driver updates - android binder driver updates - nvmem driver updates - phy driver updates - parport driver fixes - pcmcia driver fix - uio driver updates - w1 driver updates - configfs fixes - other assorted driver updates All of these have been in linux-next for a long time with no reported issues" * tag 'char-misc-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (200 commits) misc: mic: Use PTR_ERR_OR_ZERO rather than its implementation habanalabs: correctly cast variable to __le32 habanalabs: show correct id in error print habanalabs: stop using the acronym KMD habanalabs: display card name as sensors header habanalabs: add uapi to retrieve aggregate H/W events habanalabs: add uapi to retrieve device utilization habanalabs: Make the Coresight timestamp perpetual habanalabs: explicitly set the queue-id enumerated numbers habanalabs: print to kernel log when reset is finished habanalabs: replace __le32_to_cpu with le32_to_cpu habanalabs: replace __cpu_to_le32/64 with cpu_to_le32/64 habanalabs: Handle HW_IP_INFO if device disabled or in reset habanalabs: Expose devices after initialization is done habanalabs: improve security in Debug IOCTL habanalabs: use default structure for user input in Debug IOCTL habanalabs: Add descriptive name to PSOC app status register habanalabs: Add descriptive names to PSOC scratch-pad registers habanalabs: create two char devices per ASIC habanalabs: change device_setup_cdev() to be more generic ...
