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: intel_telemetry: Get rid of custom macro

platform/x86: intel_telemetry: report debugfs failure

2018-10-19T16:23:34Z

On some Goldmont based systems such as ASRock J3455M the BIOS may not enable the IPC1 device that provides access to the PMC and PUNIT. In such scenarios, the IOSS and PSS resources from the platform device can not be obtained and result in a invalid telemetry_plt_config which is an internal data structure that holds platform config and is maintained by the telemetry platform driver. This is also applicable to the platforms where the BIOS supports IPC1 device under debug configurations but IPC1 is disabled by user or the policy. This change allows user to know the reason for not seeing entries under /sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

x86/cpu: Sanitize FAM6_ATOM naming

platform/x86: intel_telemetry: Improve S0ix logs

2017-11-27T11:39:11Z

Suspend with shallow wakes is not a useful parameter since the phenomena does not exist on deployed devices and is only a parameter of use during device power-on phase. The field always reads zero. Additionally there are other easier methods to detect it, e.g., if the S0ix counter increments by more than one during suspend. Hence the field is superfluous and can be removed. This patch also slightly renames the S0ix total field for better viewability. Signed-off-by: Souvik Kumar Chakravarty Signed-off-by: Andy Shevchenko

platform/x86: intel_telemetry: Fix suspend stats

2017-11-27T11:39:11Z

Suspend stats are not reported consistently due to a limitation in the PMC firmware. This limitation causes a delay in updating the s0ix counters and residencies in the telemetry log upon s0ix exit. As a consequence, reading these counters from the suspend-exit notifier may result in zero read. This patch fixes this issue by cross-verifying the s0ix residencies from the GCR TELEM registers in case the counters are not incremented in the telemetry log after suspend.
