2019-10-27platform/x86: intel_int0002_vgpio: Pass irqchip when adding gpiochipLinus Walleij
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.

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.

All Loongson-3 CPU family: Code-name Brand-name PRId Loongson-3A R1 Loongson-3A1000 0x6305 Loongson-3A R2 Loongson-3A2000 0x6308 Loongson-3A R2.1 Loongson-3A2000 0x630c Loongson-3A R3 Loongson-3A3000 0x6309 Loongson-3A R3.1 Loongson-3A3000 0x630d Loongson-3A R4 Loongson-3A4000 0xc000 Loongson-3B R1 Loongson-3B1000 0x6306 Loongson-3B R2 Loongson-3B1500 0x6307 Features of R4 revision of Loongson-3A: - All R2/R3 features, including SFB, V-Cache, FTLB, RIXI, DSP, etc. - Support variable ASID bits. - Support MSA and VZ extensions. - Support CPUCFG (CPU config) and CSR (Control and Status Register) extensions. - 64 entries of VTLB (classic TLB), 2048 entries of FTLB (8-way set-associative). Now 64-bit Loongson processors has three types of PRID.IMP: 0x6300 is the classic one so we call it PRID_IMP_LOONGSON_64C (e.g., Loongson-2E/ 2F/3A1000/3B1000/3B1500/3A2000/3A3000), 0x6100 is for some processors which has reduced capabilities so we call it PRID_IMP_LOONGSON_64R (e.g., Loongson-2K), 0xc000 is supposed to cover all new processors in general (e.g., Loongson-3A4000+) so we call it PRID_IMP_LOONGSON_64G.

2019-10-01platform/chrome: wilco_ec: Add debugfs test_event fileDaniel Campello
This change introduces a new debugfs file 'test_event' that when written to causes the EC to generate a test event. This adds a second sub cmd for the test event, and pulls out send_ec_cmd to be a common helper between h1_gpio_get and test_event_set.

2019-09-20platform/x86: i2c-multi-instantiate: Derive the device name from parentHeikki Krogerus
When naming the new devices, instead of using the ACPI ID in the name as base, using the parent device's name. That makes it possible to support multiple multi-instance i2c devices of the same type in the same system. This fixes an issue seen on some Intel Kaby Lake based boards: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-INT3515-tps6598x.0' Fixes: 2336dfadfb1e ("platform/x86: i2c-multi-instantiate: Allow to have same slaves") Cc: stable@vger.kernel.org Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
