These new RTC variants all have a single alarm, like the R40 variant. For the new SoCs, start requiring a complete list of input clocks. The H616 has three required clocks. The R329 also has three required clocks (but one is different), plus an optional crystal oscillator input. The D1 RTC is identical to the one in the R329. And since these new SoCs will have a well-defined output clock order as well, they do not need the clock-output-names property.

2022-02-15mtd: spi-nor / spi / MFD: Convert intel-spi to SPI MEMMark Brown2-5/+5
Merge series from Mika Westerberg <mika.westerberg@linux.intel.com>: Based on discussion on the patch I sent some time ago here: http://lists.infradead.org/pipermail/linux-mtd/2021-June/086867.html it turns out that the preferred way to deal with the SPI flash controller drivers is through SPI MEM which is part of Linux SPI subsystem. This series does that for the intel-spi driver. This also renames the driver to follow the convention used in the SPI subsystem. The first patch improves the write protection handling to be slightly more safer. The following two patches do the conversion itself. Note the Intel SPI flash controller only allows commands such as read, write and so on and it internally uses whatever addressing etc. it figured from the SFDP on the flash device. base-commit: e783362eb54cd99b2cac8b3a9aeac942e6f6ac07

2022-02-14platform/x86: Add Intel Software Defined Silicon driverDavid E. Box1-0/+77
Intel Software Defined Silicon (SDSi) is a post manufacturing mechanism for activating additional silicon features. Features are enabled through a license activation process. The SDSi driver provides a per socket, sysfs attribute interface for applications to perform 3 main provisioning functions: 1. Provision an Authentication Key Certificate (AKC), a key written to internal NVRAM that is used to authenticate a capability specific activation payload. 2. Provision a Capability Activation Payload (CAP), a token authenticated using the AKC and applied to the CPU configuration to activate a new feature. 3. Read the SDSi State Certificate, containing the CPU configuration state. The operations perform function specific mailbox commands that forward the requests to SDSi hardware to perform authentication of the payloads and enable the silicon configuration (to be made available after power cycling). The SDSi device itself is enumerated as an auxiliary device from the intel_vsec driver and as such has a build dependency on CONFIG_INTEL_VSEC.

2022-02-14swiotlb: fix info leak with DMA_FROM_DEVICEHalil Pasic1-0/+8
The problem I'm addressing was discovered by the LTP test covering cve-2018-1000204. A short description of what happens follows: 1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV and a corresponding dxferp. The peculiar thing about this is that TUR is not reading from the device. 2) In sg_start_req() the invocation of blk_rq_map_user() effectively bounces the user-space buffer. As if the device was to transfer into it. Since commit a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in sg_build_indirect()") we make sure this first bounce buffer is allocated with GFP_ZERO. 3) For the rest of the story we keep ignoring that we have a TUR, so the device won't touch the buffer we prepare as if the we had a DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device and the buffer allocated by SG is mapped by the function virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here scatter-gather and not scsi generics). This mapping involves bouncing via the swiotlb (we need swiotlb to do virtio in protected guest like s390 Secure Execution, or AMD SEV). 4) When the SCSI TUR is done, we first copy back the content of the second (that is swiotlb) bounce buffer (which most likely contains some previous IO data), to the first bounce buffer, which contains all zeros. Then we copy back the content of the first bounce buffer to the user-space buffer. 5) The test case detects that the buffer, which it zero-initialized, ain't all zeros and fails. One can argue that this is an swiotlb problem, because without swiotlb we leak all zeros, and the swiotlb should be transparent in a sense that it does not affect the outcome (if all other participants are well behaved). Copying the content of the original buffer into the swiotlb buffer is the only way I can think of to make swiotlb transparent in such scenarios. So let's do just that if in doubt, but allow the driver to tell us that the whole mapped buffer is going to be overwritten, in which case we can preserve the old behavior and avoid the performance impact of the extra bounce.

2022-02-14kbuild: Add environment variables for userprogs flagsElliot Berman2-0/+13
Allow additional arguments be passed to userprogs compilation. Reproducible clang builds need to provide a sysroot and gcc path to ensure the same toolchain is used across hosts. KCFLAGS is not currently used for any user programs compilation, so add new USERCFLAGS and USERLDFLAGS which serves similar purpose as HOSTCFLAGS/HOSTLDFLAGS. Clang might detect GCC installation on hosts which have it installed to a default location in /. With addition of these environment variables, you can specify flags such as: $ make USERCFLAGS=--sysroot=/path/to/sysroot This can also be used to specify different sysroots such as musl or bionic which may be installed on the host in paths that the compiler may not search by default.

The max77693 LED device node should not take an unit address, because it is instantiated from a max77693 I2C parent device node. This also splits all examples to separate DTS examples because they are actually independent.
