2019-11-25platform/x86: hp-wmi: Fix ACPI errors caused by too small bufferHans de Goede
The HP WMI calls may take up to 128 bytes of data as input, and the AML methods implementing the WMI calls, declare a couple of fields for accessing input in different sizes, specifycally the HWMC method contains: CreateField (Arg1, 0x80, 0x0400, D128) Even though we do not use any of the WMI command-types which need a buffer of this size, the APCI interpreter still tries to create it as it is declared in generoc code at the top of the HWMC method which runs before the code looks at which command-type is requested. This results in many of these errors on many different HP laptop models: [ 14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236) [ 14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543) [ 14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543) This commit increases the size of the data element of the bios_args struct to 128 bytes fixing these errors.

2019-11-21platform/chrome: cros_ec: handle MKBP more events flagEnrico Granata
The ChromeOS EC has support for signaling to the host that a single IRQ can serve multiple MKBP (Matrix KeyBoard Protocol) events. Doing this serves an optimization purpose, as it minimizes the number of round-trips into the interrupt handling machinery, and it proves beneficial to sensor timestamping as it keeps the desired synchronization of event times between the two processors. This patch adds kernel support for this EC feature, allowing the ec_irq to loop until all events have been served.

We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. 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. We may revisit this code later and pull reqular shared IRQ handler into gpiolib, so leave a FIXME.

2019-10-23compat_ioctl: move more drivers to compat_ptr_ioctlArnd Bergmann
The .ioctl and .compat_ioctl file operations have the same prototype so they can both point to the same function, which works great almost all the time when all the commands are compatible. One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.

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.
