2019-05-14thermal: generic-adc: make lookup table optionalJean-Francois Dagenais
Certain ADC channels, such as the xilinx-ams temperature channels, give milliCelcius already when read with iio_read_channel_processed. Rather than having to provide a 1:1 dummy lookup table, simply allow to bypass the mechanism.

2019-05-14ACPI: PM: Set enable_for_wake for wakeup GPEs during suspend-to-idleRajat Jain
I noticed that recently multiple systems (chromebooks) couldn't wake from S0ix using LID or Keyboard after updating to a newer kernel. I bisected and it turned up commit f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle"). I checked that the issue got fixed if that commit was reverted. I debugged and found that although PNP0C0D:00 (representing the LID) is wake capable and should wakeup the system per the code in acpi_wakeup_gpe_init() and in drivers/acpi/button.c: localhost /sys # cat /proc/acpi/wakeup Device S-state Status Sysfs node LID0 S4 *enabled platform:PNP0C0D:00 CREC S5 *disabled platform:GOOG0004:00 *disabled platform:cros-ec-dev.1.auto *disabled platform:cros-ec-accel.0 *disabled platform:cros-ec-accel.1 *disabled platform:cros-ec-gyro.0 *disabled platform:cros-ec-ring.0 *disabled platform:cros-usbpd-charger.2.auto *disabled platform:cros-usbpd-logger.3.auto D015 S3 *enabled i2c:i2c-ELAN0000:00 PENH S3 *enabled platform:PRP0001:00 XHCI S3 *enabled pci:0000:00:14.0 GLAN S4 *disabled WIFI S3 *disabled pci:0000:00:14.3 localhost /sys # On debugging, I found that its corresponding GPE is not being enabled. The particular GPE's "gpe_register_info->enable_for_wake" does not have any bits set when acpi_enable_all_wakeup_gpes() comes around to use it. I looked at code and could not find any other code path that should set the bits in "enable_for_wake" bitmask for the wake enabled devices for s2idle. [I do see that it happens for S3 in acpi_sleep_prepare()]. Thus I used the same call to enable the GPEs for wake enabled devices, and verified that this fixes the regression I was seeing on multiple of my devices. [ rjw: The problem is that commit f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle") forgot to add the acpi_enable_wakeup_devices() call for s2idle along with acpi_enable_all_wakeup_gpes(). ] Fixes: f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle") Link: https://bugzilla.kernel.org/show_bug.cgi?id=203579 Signed-off-by: Rajat Jain <rajatja@google.com> [ rjw: Subject & changelog ] Cc: 5.0+ <stable@vger.kernel.org> # 5.0+ Signed-off-by: Rafael J.

2019-05-14backlight: lm3630a: Add firmware node supportBrian Masney
Add fwnode support to the lm3630a driver and optionally allow configuring the label, default brightness level, and maximum brightness level. The two outputs can be controlled by bank A and B independently or bank A can control both outputs. If the platform data was not configured, then the driver defaults to enabling both banks. This patch changes the default value to disable both banks before parsing the firmware node so that just a single bank can be enabled if desired. There are no in-tree users of this driver. Driver was tested on a LG Nexus 5 (hammerhead) phone.
