spi: Fix null dereference on suspend

2023-11-10T13:54:58Z

A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. Spi transfer context resumes and spi_finalize_current_message() is called which dereferences cur_msg (which is now NULL) Wait for synchronous transfers to complete before suspending by acquiring the bus mutex and setting/checking a suspend flag.

spi: Merge up fix

One small fix that didn't seem worth sending before the merge window.

spi: omap2-mcspi: Add FIFO support without DMA

2023-10-23T12:30:05Z

Currently, the built-in 64-byte FIFO on the MCSPI controller is not enabled in PIO mode and is used only when DMA is enabled. Enable the FIFO in PIO mode by default for transactions larger than the FIFO depth and fallback only if FIFO is not available. When DMA is not enabled, it is efficient to enable the RX FIFO almost full and TX FIFO almost empty events after each FIFO fill instead of each word. Update omap2_mcspi_set_fifo() to enable the events accordingly and also rely on OMAP2_MCSPI_CHSTAT_RXS for the last transfer instead of the FIFO events to handle the case when the transfer size is not a multiple of FIFO depth.

spi: stm32: Explicitly include correct DT includes

2023-10-17T20:38:51Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-10-16T15:08:39Z

Export acpi_spi_find_controller_by_adev() so that ACPI glue code which wants to dynamically create a spi_device using acpi_spi_device_alloc() or spi_new_device() on a controller, to which the code does not already have a reference, can find the controller.

spi: nxp-fspi: use the correct ioremap function

AHB memory as MMIO should be mapped with ioremap rather than ioremap_wc, which should have been used initially just to handle unaligned access as a workaround.
