[linux-yocto] [PATCH 3/3] features: Create mfd-intel-lpss feature and use where appropriate
No need to have these similar configurations spread all around. Also solves a warning where skylake tried to set MFD_INTEL_LPSS to build as a module, but MFD_INTEL_LPSS_PCI in broxton hits a select and forces it to built in.

[linux-yocto] [PATCH 2/3] features/iio: Set IIO_BUFFER_CB to =m instead of =y
CONFIG_IIO_BUFFER_CB is a tristate and CONFIG_IIO is set to =m, so CONFIG_IIO_BUFFER_CB gets forced to =m anyway. Fixes a kernel_configcheck warning we get with the new tools.

[linux-yocto] [PATCH] x86/tsc: Set X86_FEATURE_TSC_RELIABLE to skip refined calibration
Backport: Submitted upstream [v2]. [https://patchwork.kernel.org/patch/9284339/] On some newer Intel x86 processors/SoCs the TSC frequency can be directly calculated by factors read from specific MSR registers or from a cpuid leaf (0x15). TSC frequency calculated by native msr/cpuid is absolutely accurate so we should always skip calibrating TSC aginst another clock, e.g. PIT, HPET, etc. So we want to skip the refined calibration by setting the X86_FEATURE_TSC_RELIABLE flag. Existing code setting the flag by set_cpu_cap() doesn't work as the flag is cleared later in identify_cpu(). A cpu caps flag is not cleared only if it's set by setup_force_cpu_cap(). This patch converted set_cpu_cap() to setup_force_cpu_cap() to ensure refined calibration is skipped. We had a test on Intel CherryTrail platform: the 24 hours time drift is 3.6 seconds if refined calibration was not skipped while the drift is less than 0.6 second when refined calibration was skipped. Correctly setting the X86_FEATURE_TSC_RELIABLE flag also guarantees TSC is not monitored by timekeeping watchdog because on most of these system TSC is the only reliable clocksource. HPET, for instance, works but may not be reliable. So kernel may report a physically reliable TSC is not reliable just because a physically not reliable HPET is acting as timekeeping watchdog.
