2024-11-21spi-imx: prevent overflow when estimating transfer timeAntonio Quartulli
The words delay is computed by multiplying two unsigned ints and by adding up the result to a u64 variable. The multiplication, however, is performed with 32bit math thus losing data when the actual result is larger than UINT32_MAX. Fix the operation by casting the first operand to u64, thus forcing the multiplication to be performed with 64bit math.

2024-11-14spi: imx: support word delay in ecspiMark Brown
Merge series from Jonas Rebmann <jre@pengutronix.de>: The i.MX SPI controller supports inserting a configurable delay between subsequent words, which is needed for some slower devices that couldn't keep up otherwise. This patch series introduces support for the word delay parameters for i.MX51 onwards. The SPI clock (CSRC=0) was chosen as the clock source over the also available 32.768 KHz Low-Frequency Reference Clock (CSRC=1). The sample period control bits (SAMPLE_PERIOD) are set to the selected word delay converted to SPI clock cycles. A deviation from the requested number of wait cycles and the actual word delay was observed via both software timings and oscilloscope measurements and accounted for. The Chip Select Delay Control bits in the Sample Period Control Register remain zero. Behaviour on i.MX35 and earlier, where the CSPI interface is used, remains unchanged.
2024-11-13spi: imx: support word delayJonas Rebmann
Implement support for the word delay feature of i.MX51 (and onwards) via the ECSPI interface. Convert the requested delay to SPI cycles and account for an extra inter-word delay inserted by the controller in addition to the requested number of cycles, which was observed when testing this patch. Disable dynamic burst when word delay is set. As the configurable delay period in the controller is inserted after bursts, the burst length must equal the word length. Account for word delay in the transfer time estimation for polling_limit_us.

2024-11-06spi: apple: Add driver for Apple SPI controllerHector Martin
This SPI controller is present in Apple SoCs such as the M1 (t8103) and M1 Pro/Max (t600x). It is a relatively straightforward design with two 16-entry FIFOs, arbitrary transfer sizes (up to 2**32 - 1) and fully configurable word size up to 32 bits. It supports one hardware CS line which can also be driven via the pinctrl/GPIO driver instead, if desired. TX and RX can be independently enabled. There are a surprising number of knobs for tweaking details of the transfer, most of which we do not use right now. Hardware CS control is available, but we haven't found a way to make it stay low across multiple logical transfers, so we just use software CS control for now. There is also a shared DMA offload coprocessor that can be used to handle larger transfers without requiring an IRQ every 8-16 words, but that feature depends on a bunch of scaffolding that isn't ready to be upstreamed yet, so leave it for later. The hardware shares some register bit definitions with spi-s3c24xx which suggests it has a shared legacy with Samsung SoCs, but it is too different to warrant sharing a driver.

2024-10-09spi: intel: Add protected and locked attributesAlexander Usyskin
The manufacturing access to the PCH/SoC SPI device is traditionally performed via userspace driver accessing registers via /dev/mem but due to security concerns /dev/mem access is being much restricted, hence the reason for utilizing dedicated Intel PCH/SoC SPI controller driver, which is already implemented in the Linux kernel. Intel PCH/SoC SPI controller protects the flash storage via two mechanisms one is the via region protection registers and second via BIOS lock. The BIOS locks only the BIOS regions usually 0 and/or 6. The device always boots with BIOS lock set, but during manufacturing the BIOS lock has to be lifted in order to enable the write access. This can be done by passing "writeable=1" in the command line when the driver is loaded. This "locked" state is exposed through new sysfs attributes (intel_spi_locked, intel_spi_bios_locked). Second, also the region protection status is exposed via sysfs attribute (intel_spi_protected) as the manufacturing will need the both files in order to validate that the device is properly sealed.

2024-10-08driver core: Add device probe log helper dev_warn_probe()Dragan Simic
Some drivers can still provide their functionality to a certain extent even when some of their resource acquisitions eventually fail. In such cases, emitting errors isn't the desired action, but warnings should be emitted instead. To solve this, introduce dev_warn_probe() as a new device probe log helper, which behaves identically as the already existing dev_err_probe(), while it produces warnings instead of errors. The intended use is with the resources that are actually optional for a particular driver. While there, copyedit the kerneldoc for dev_err_probe() a bit, to simplify its wording a bit, and reuse it as the kerneldoc for dev_warn_probe(), with the necessary wording adjustments, of course.

The blank line causes execve() to fail: # strace ./postinst execve("./postinst", ...) = -1 ENOEXEC (Exec format error) strace: exec: Exec format error +++ exited with 1 +++ However running the scripts via shell does work (at least with bash) because the shell attempts to execute the file as a shell script when execve() fails.

2024-10-06platform/x86: x86-android-tablets: Fix use after free on ↵Hans de Goede
platform_device_register() errors x86_android_tablet_remove() frees the pdevs[] array, so it should not be used after calling x86_android_tablet_remove(). When platform_device_register() fails, store the pdevs[x] PTR_ERR() value into the local ret variable before calling x86_android_tablet_remove() to avoid using pdevs[] after it has been freed.
