2019-11-21platform/x86: intel_pmc_core: Add Comet Lake (CML) platform support to ↵Gayatri Kammela
intel_pmc_core driver Add Comet Lake to the list of the platforms that intel_pmc_core driver supports for pmc_core device. Just like Ice Lake, Comet Lake can also reuse all the Cannon Lake PCH IPs. No additional effort is needed to enable but to simply reuse them.

2019-11-21platform/x86: intel_pmc_core: Fix the SoC naming inconsistencyGayatri Kammela
Intel's SoCs follow a naming convention which spells out the SoC name as two words instead of one word (E.g: Cannon Lake vs Cannonlake). Thus fix the naming inconsistency across the intel_pmc_core driver, so future SoCs can follow the naming consistency as below.

It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level.

2019-11-07tools/power/x86/intel-speed-select: Support platform with limited Intel(R) ↵Srinivas Pandruvada
Speed Select There are some platforms, where there limited support of Intel(R) SST features. Here perf-profile has only one base configuration and limited support of commands. But still has support for discovery of base-freq and turbo-freq features. So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies. Here present base frequency by reading cpufreq base freq and turbo frequency by reading MSR 0x1AD. - Don't display any field, which has value == 0.

For chained irqchips this is a pretty straight-forward conversion. This driver requests the IRQ directly in the driver so it needs to pass a NULL parent handler.

2019-10-15platform/mellanox: Add bootctl driver for Mellanox BlueField SocLiming Sun
This commit adds the bootctl platform driver for Mellanox BlueField Soc, which queries secure state and controls the eMMC boot partition swapping by sending SMC calls to ATF running at EL3. Below are the sequences of typical use case. 1. User requests boot partition swapping, which could be on-demand or during boot-image upgrade via UEFI capsule; 2. This bootctl driver handles the request and sends SMC call to ATF. ATF programs register BREADCRUMB0 which has value preserved during warm reset. It also programs eMMC to swap the boot partition; 3. After software reset (rebooting), ATF BL1 (BootRom) checks register BREADCRUMB0 and enable watchdog if configured; 4. If booting fails, the watchdog timer will trigger rebooting. In such case, ATF Boot ROM will switch the boot partition back to the previous one. This is a robust feature and used to prevent failure during boot partition upgrade.

2019-10-15platform/x86: intel_cht_int33fe: Split code to Micro-B and Type-CYauhen Kharuzhy
Existing intel_cht_int33fe ACPI pseudo-device driver assumes that hardware has Type-C connector and register related devices described as I2C connections in the _CRS resource. There is at least one hardware (Lenovo Yoga Book YB1-91L/F) with Micro-B USB connector exists. It has INT33FE device in the DSDT table but there are only two I2C connection described: PMIC and BQ27452 battery fuel gauge. Splitting existing INT33FE driver allow to maintain code for USB Micro-B (or AB) connector variant separately and make it simpler. Split driver to intel_cht_int33fe_common.c and intel_cht_int33fe_{microb,typec}.c. Compile all this sources to one .ko module to make user experience easier.

2019-10-15platform/x86: toshiba_acpi: do not select INPUT_POLLDEVDmitry Torokhov
The driver does not use polling mode of input devices, and this config option is going away, so let's not reference it. Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2019-10-15platform/x86: peaq-wmi: switch to using polled mode of input devicesDmitry Torokhov
We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts peaq-wmi driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. Because the new polling coded does not allow peeking inside the poller structure to get the poll interval, we change the "debounce" process to operate on the time basis, instead of counting events. We also fix error handling during initialization, as previously we leaked input device structure when we failed to register it.

We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts Asus laptop driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. Also removed no longed needed set_bit(EV_ABS, ...) as input_set_abs_oarams() does it for us.
