Pull x86 platform driver updates from Darren Hart: - Move the Dell dcdbas and dell_rbu drivers into platform/drivers/x86 as they are closely coupled with other drivers in this location. - Improve _init* usage for acerhdf and fix some usage issues with messages and module parameters. - Simplify asus-wmi by calling ACPI/WMI methods directly, eliminating workqueue overhead, eliminate double reporting of keyboard backlight. - Fix wake from USB failure on Bay Trail devices (intel_int0002_vgpio). - Notify intel_telemetry users when IPC1 device is not enabled. - Update various drivers with new laptop model IDs. - Update several intel drivers to use SPDX identifers and order headers alphabetically. * tag 'platform-drivers-x86-v4.20-1' of git://git.infradead.org/linux-platform-drivers-x86: (64 commits) HID: asus: only support backlight when it's not driven by WMI platform/x86: asus-wmi: export function for evaluating WMI methods platform/x86: asus-wmi: Only notify kbd LED hw_change by fn-key pressed platform/x86: wmi: declare device_type structure as constant platform/x86: ideapad: Add Y530-15ICH to no_hw_rfkill platform/x86: Add Intel AtomISP2 dummy / power-management driver platform/x86: touchscreen_dmi: Add min-x and min-y settings for various models platform/x86: touchscreen_dmi: Add info for the Onda V80 Plus v3 tablet platform/x86: touchscreen_dmi: Add info for the Trekstor Primetab T13B tablet platform/x86: intel_telemetry: Get rid of custom macro platform/x86: intel_telemetry: report debugfs failure MAINTAINERS: intel_telemetry: Update maintainers info platform/x86: Add LG Gram laptop special features driver platform/x86: asus-wmi: Simplify the keyboard brightness updating process platform/x86: touchscreen_dmi: Add info for the Trekstor Primebook C11 convertible platform/x86: mlx-platform: Properly use mlxplat_mlxcpld_msn201x_items MAINTAINERS: intel_pmc_core: Update MAINTAINERS firmware: dcdbas: include linux/io.h platform/x86: intel-wmi-thunderbolt: Add dynamic debugging platform/x86: intel-wmi-thunderbolt: Convert to use SPDX identifier ...

platform/x86: asus-wmi: export function for evaluating WMI methods

2018-10-31T14:11:40Z

Export asus_wmi_evaluate_method() and related headers for use by other drivers. hid-asus is going to use this to avoid advertising that it has a keyboard backlight when the keyboard backlight is controlled via WMI. Signed-off-by: Daniel Drake Signed-off-by: Andy Shevchenko

platform/x86: asus-wmi: Only notify kbd LED hw_change by fn-key pressed

2018-10-31T14:11:40Z

Since commit dbb3d78f61ba ("platform/x86: asus-wmi: Call led hw_changed API on kbd brightness change"), asus-wmi directly changes the keyboard LED brightness when the keyboard brightness keys are pressed, raising the appropriate notification. However, this notification was unintentionally also being raised during boot and resume from suspend. This was resulting in userspace showing the keyboard LED OSD on resume for no good reason. Move the keyboard LED brightness changed notification from kbd_led_update to the new kbd_led_set_by_kbd function which is only called from the keyboard brightness function keys codepath.

platform/x86: wmi: declare device_type structure as constant

2018-10-31T14:11:39Z

The only usage of device_type structure is getting stored as a reference in the type field of device structure. This type field is declared const. Therefore, the device_type structure can never be modified and can be declared as const. Signed-off-by: Bhumika Goyal Signed-off-by: Andy Shevchenko

platform/x86: Add Intel AtomISP2 dummy / power-management driver

2018-10-29T12:02:14Z

The Image Signal Processor found on Cherry Trail devices is brought up in D0 state on devices which have camera sensors attached to it. The ISP will not enter D3 state again without some massaging of its registers beforehand and the ISP not being in D3 state blocks the SoC from entering S0ix modes. There was a driver for the ISP in drivers/staging but that got removed again because it never worked. It does not seem likely that a real driver for the ISP will be added to the mainline kernel anytime soon. This commit adds a dummy driver which contains the necessary magic from the staging driver to powerdown the ISP, so that Cherry Trail devices where the ISP is used will properly use S0ix modes when suspended. Together with other recent S0ix related fixes this allows S0ix modes to be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

platform/x86: touchscreen_dmi: Add min-x and min-y settings for various models

2018-10-29T10:21:57Z

Add min-x and min-y settings now that we've support for this and for some models also update the width/height settings with slighly more accurate values. This fixes touches along the edges registering at the wrong coordinates. While at it also set max-fingers to 10 in a couple of cases where the touchpad can handle 10 fingers (rather then the default 5) and that was missing.
