| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds possibility to invert heartbeat blinking. The inverted LED is more time ON then OFF. It's because it looks better when the heartbeat LED is next to other LED which is most time ON. The invert value is exported same way via sysfs in file invert like oneshot.

* | leds:lp55xx: Correct Kconfig dependency for f/w user helperTakashi Iwai2015-09-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit [b67893206fc0: leds:lp55xx: fix firmware loading error] tries to address the firmware file handling with user helper, but it sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I merged the OPAL support for the powernv LEDS driver I missed a hunk.

Instead those values are moved into the driver, which is the only place they are used.

PowerNV platform has below type of LEDs: - System attention Indicates there is a problem with the system that needs attention. - Identify Helps the user locate/identify a particular FRU or resource in the system. - Fault Indicates there is a problem with the FRU or resource at the location with which the indicator is associated. We register classdev structures for all individual LEDs detected on the system through LED specific device tree nodes. Device tree nodes specify what all kind of LEDs present on the same location code. It registers LED classdev structure for each of them. All the system LEDs can be found in the same regular path /sys/class/leds/. We don't use LED colors. We use LED node and led-types property to form LED classdev. Our LEDs have names in this format. <location_code>:<attention|identify|fault> Any positive brightness value would turn on the LED and a zero value would turn off the LED. The driver will return LED_FULL (255) for any turned on LED and LED_OFF (0) for any turned off LED. The platform level implementation of LED get and set state has been achieved through OPAL calls. These calls are made available for the driver by exporting from architecture specific codes.

So drivers needs to export the I2C id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and I2C id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same I2C device name for example. To avoid the above, the I2C core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes.

| * | leds:lp55xx: use the private data instead of updating I2C device platform dataMilo Kim2015-08-286-33/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, lp55xx_of_populate_pdata() allocates lp55xx_platform_data if it's null. And it parses the DT and copies values into the 'client->dev.platform_data'. This may have architectural issue. Platform data is configurable through the DT or I2C board info inside the platform area. However, lp55xx common driver changes this configuration when it is loaded. So 'client->dev.platform_data' is not null anymore. Eventually, the driver initialization is not identical when it's unloaded and loaded again. The lp55xx common driver should use the private data, 'lp55xx_chip->pdata' instead of changing the original platform data. So, lp55xx_of_populate_pdata() is modified as follows. * Do not update 'dev->platform_data'. Return the pointer of new allocated lp55xx_platform_data. Then the driver points it to private data, 'lp55xx_chip->pdata'. * Each lp55xx driver checks the pointer and handles an error case. Then, original platform data configuration will be kept regardless of loading or unloading the driver. The driver allocates the memory and copies them from the DT if it's NULL. After the driver is loaded again, 'client->dev.platform_data' is same as initial load, so the driver is initialized identically.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the board n090401 (Seagate NAS 4-Bay), some of the LEDs are handled by the leds-ns2 driver. This LEDs are connected to an I2C GPIO expander (PCA95554PW) which means that GPIO access may sleep. This patch makes leds-ns2 compatible with such GPIOs by using the *_cansleep() variant of the GPIO functions. As a drawback this functions can't be used safely in a timer context (with the timer LED trigger for example). To fix this issue, a workqueue mechanism (copied from the leds-gpio driver) is used. Note that this patch also updates slightly the ns2_led_sata_store function. The LED state is now retrieved from cached values instead of reading the GPIOs previously. This prevents ns2_led_sata_store from working with a stale LED state (which may happen when a delayed work is pending).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO values to LED mode) is different from the one used on other boards supported by the leds-ns2 driver. With this patch the hardcoded mapping is removed from leds-ns2. Now, it must be defined either in the platform data (if an old-fashion board setup file is used) or in the DT node. In order to allow the later, this patch also introduces a modes-map property for the leds-ns2 DT binding.
