2025-06-26iio: cros_ec_sensors: add cros_ec_activity driverGwendal Grignou
ChromeOS EC can report activity information derived from the accelerometer: - Reports on-body/off-body as a proximity event. - Reports significant motion as an activity event. This new sensor is a virtual sensor, included only when the EC firmware is compiled with the appropriate module.

Also remove unnecessary use of get_unaligned_le16() and explicitly include linux/types.h e.g. for __le16 while we are fixing this up.

2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

2025-06-08tools/power turbostat: Clean up add perf/msr counter logicZhang Rui
Increase the code readability by moving the no_perf/no_msr flag and the cai->perf_name/cai->msr sanity checks into the counter probe functions. No functional change. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
