2016-03-14leds: wm831x-status: Use devm_led_classdev_registerAmitoj Kaur Chawla
Switch to resource-managed function devm_led_classdev_register instead of led_classdev_register and remove unneeded led_classdev_unregister. Also, remove platform_set_drvdata from probe function and the remove function, wm831x_status_remove as it is now has nothing to do. The Coccinelle semantic patch used to make this change is as follows: //<smpl> @platform@ identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e; @@ probefn(struct platform_device *pdev, ...) { ... e = - led_classdev_register + devm_led_classdev_register (...); ... ?- led_classdev_unregister(...); ... } @remove depends on prb@ identifier platform.removefn; @@ removefn(...) { ... ?- led_classdev_unregister(...); ... } //</smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>

2016-03-14leds: Add SN3218 and SN3216 support to the IS31FL32XX driverDavid Rivshin
Si-En Technology was acquired by ISSI in 2011, and it appears that the IS31FL3218/IS31FL3216 are just rebranded SN3218/SN3216 devices. Add the "si-en,sn3218" and "si-en,sn3216" compatible strings into the IS31FL32XX driver as aliases for the issi equivalents, and update binding documentation. Datasheets: IS31FL3218: http://www.issi.com/WW/pdf/31FL3218.pdf SN3218: http://www.si-en.com/uploadpdf/s2011517171720.pdf IS31FL3216: http://www.issi.com/WW/pdf/31FL3216.pdf SN3216: http://www.si-en.com/uploadpdf/SN3216201152410148.pdf Signed-off-by: David Rivshin <drivshin@allworx.com> Acked-by: Rob Herring <robh@kernel.org> Tested-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
2016-03-14leds: Add driver for the ISSI IS31FL32xx family of LED controllersDavid Rivshin
The IS31FL32xx family of LED controllers are I2C devices with multiple constant-current channels, each with independent 256-level PWM control. Datasheets: http://www.issi.com/US/product-analog-fxled-driver.shtml This has been tested on the IS31FL3236 and IS31FL3216, on an ARM (TI am335x) platform. The programming paradigm of these devices is similar in the following ways: - All registers are 8 bit - All LED control registers are write-only - Each LED channel has a PWM register (0-255) - PWM register writes are shadowed until an Update register is poked - All have a concept of Software Shutdown, which disables output However, there are some differences in devices: - 3236/3235 have a separate Control register for each LED, (3218/3216 pack the enable bits into fewer registers) - 3236/3235 have a per-channel current divisor setting - 3236/3235 have a Global Control register that can turn off all LEDs - 3216 is unique in a number of ways - OUT9-OUT16 can be configured as GPIOs instead of LED controls - LEDs can be programmed with an 8-frame animation, with programmable delay between frames - LEDs can be modulated by an input audio signal - Max output current can be adjusted from 1/4 to 2x globally - Has a Configuration register instead of a Shutdown register This driver currently only supports the base PWM control function of these devices. The following features of these devices are not implemented, although it should be possible to add them in the future: - All devices are capable of going into a lower-power "software shutdown" mode. - The is31fl3236 and is31fl3235 can reduce the max output current per-channel with a divisor of 1, 2, 3, or 4. - The is31fl3216 can use some LED channels as GPIOs instead. - The is31fl3216 can animate LEDs in hardware. - The is31fl3216 can modulate LEDs according to an audio input. - The is31fl3216 can reduce/increase max output current globally.

2016-03-14leds: core: avoid error message when a USB LED device is unpluggedHeiner Kallweit
When a USB LED device is unplugged the remove call chain calls led_classdev_unregister which tries to switch the LED off. As the device has been removed already this results in a ENODEV error message in dmesg. Avoid this error message by ignoring ENODEV in calls from led_classdev_unregister if the LED device is flagged as pluggable. Therefore a new flag LED_HW_PLUGGABLE was introduced which should be set by all LED drivers handling pluggable LED devices (mainly USB LED devices).

2016-03-12PCI: Remove arch-specific IORESOURCE_ROM_SHADOW size from sysfsBjorn Helgaas
When pci_create_sysfs_dev_files() created the "rom" sysfs file, it set the sysfs file size to the actual size of a ROM BAR, or if there was no ROM BAR but the platform provided a shadow copy in RAM, to 0x20000. 0x20000 is an arch-specific length that should not be baked into the PCI core. Every place that sets IORESOURCE_ROM_SHADOW also sets the size of the PCI_ROM_RESOURCE, so use the resource length always. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
