* fpga: xilinx-pr-decoupler: Remove clk_get error message for probe deferShubhrajyoti Datta2020-01-101-1/+2
| | | | | | | | | | 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.

* fpga: dfl: fme: add power management supportWu Hao2019-10-171-0/+207
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

They're all more or less cleanup patches: - Carlos' patch addresses a checkpatch warning - My first patch changes the return type of a function to align it with the fact that nothing checks the return value and it uncoditionally returned 0 anyways - My second patch somehow fell through the cracks before and cleans up the FPGA bridge bindings by consolidating them instead of repeating the same paragraph over and over again.

After disable SRIOV, it requires user to invoke this PORT_ASSIGN ioctl to attach the port back to PF. Ioctl interfaces: * DFL_FPGA_FME_PORT_RELEASE Release platform device of given port, it deletes port platform device to remove related userspace interfaces on PF. After this function, then it's safe to configure PF/VF access mode to VF, and enable VFs via SRIOV. * DFL_FPGA_FME_PORT_ASSIGN Assign platform device of given port back to PF.

Besides that there are many changes scattered among various LED class drivers and triggers. LED naming related improvements: - add new 'function' and 'color' fwnode properties and deprecate 'label' property which has been frequently abused for conveying vendor specific names that have been available in sysfs anyway - introduce a set of standard LED_FUNCTION* definitions - introduce a set of standard LED_COLOR_ID* definitions - add a new {devm_}led_classdev_register_ext() API with the capability of automatic LED name composition basing on the properties available in the passed fwnode; the function is backwards compatible in a sense that it uses 'label' data, if present in the fwnode, for creating LED name - add tools/leds/get_led_device_info.sh script for retrieving LED vendor, product and bus names, if applicable; it also performs basic validation of an LED name - update following drivers and their DT bindings to use the new LED registration API: - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114, leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt Other LED class improvements: - replace {devm_}led_classdev_register() macros with inlines - allow to call led_classdev_unregister() unconditionally - switch to use fwnode instead of be stuck with OF one LED triggers improvements: - led-triggers: - fix dereferencing of null pointer - fix a memory leak bug - ledtrig-gpio: - GPIO 0 is valid Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer, more complete driver exists, based on a generic driver for the AMD SOCs gpio-controller, supporting LEDs as well other devices: - drop profile field from priv data - drop iosize field from priv data - drop enum_apu_led_platform_types - drop superseeded apu2/3 led support - add pr_fmt prefix for better log output - fix error message on probing failure Other misc fixes and improvements to existing LED class drivers: - leds-ns2, leds-max77650: - add of_node_put() before return - leds-pwm, leds-is31fl32xx: - use struct_size() helper - leds-lm3697, leds-lm36274, leds-lm3532: - switch to use fwnode_property_count_uXX() - leds-lm3532: - fix brightness control for i2c mode - change the define for the fs current register - fixes for the driver for stability - add full scale current configuration - dt: Add property for full scale current. - avoid potentially unpaired regulator calls - move static keyword to the front of declarations - fix optional led-max-microamp prop error handling - leds-max77650: - add of_node_put() before return - add MODULE_ALIAS() - Switch to fwnode property API - leds-as3645a: - fix misuse of strlcpy - leds-netxbig: - add of_node_put() in netxbig_leds_get_of_pdata() - remove legacy board-file support - leds-is31fl319x: - simplify getting the adapter of a client - leds-ti-lmu-common: - fix coccinelle issue - move static keyword to the front of declaration - leds-syscon: - use resource managed variant of device register - leds-ktd2692: - fix a typo in the name of a constant - leds-lp5562: - allow firmware files up to the maximum length - leds-an30259a: - fix typo - leds-pca953x: - include the right header" * tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds: (72 commits) leds: lm3532: Fix optional led-max-microamp prop error handling led: triggers: Fix dereferencing of null pointer leds: ti-lmu-common: Move static keyword to the front of declaration leds: lm3532: Move static keyword to the front of declarations leds: trigger: gpio: GPIO 0 is valid leds: pwm: Use struct_size() helper leds: is31fl32xx: Use struct_size() helper leds: ti-lmu-common: Fix coccinelle issue in TI LMU leds: lm3532: Avoid potentially unpaired regulator calls leds: syscon: Use resource managed variant of device register leds: Replace {devm_}led_classdev_register() macros with inlines leds: Allow to call led_classdev_unregister() unconditionally leds: lm3532: Add full scale current configuration dt: lm3532: Add property for full scale current. leds: lm3532: Fixes for the driver for stability leds: lm3532: Change the define for the fs current register leds: lm3532: Fix brightness control for i2c mode leds: Switch to use fwnode instead of be stuck with OF one leds: max77650: Switch to fwnode property API led: triggers: Fix a memory leak bug ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current driver checks if input bitstream file size is aligned or not per PR data width (default 32bits). It requires one additional step for end user when they generate the bitstream file, padding extra zeros to bitstream file to align its size per PR data width, but they don't have to as hardware will drop extra padding bytes automatically. In order to simplify the user steps, this patch aligns PR buffer size per PR data width in driver, to allow user to pass unaligned size bitstream files to driver.

The most "notable" one here is the kernel headers in proc^Wsysfs fixes. Those changes move the header file info into sysfs and fixes the build issues that you reported. Other than that, a bunch of small habanalabs driver fixes, some fpga driver fixes, and a few other tiny driver fixes.
