2023-09-25spi: dt-bindings: qup: Document interconnectsStephan Gerhold
When the SPI QUP controller is used together with a DMA engine it needs to vote for the interconnect path to the DRAM. Otherwise it may be unable to access the memory quickly enough.

2023-09-25spi: qup: Parse OPP table for DVFS supportStephan Gerhold
Parse the OPP table from the device tree and use dev_pm_opp_set_rate() instead of clk_set_rate() to allow making performance state for power domains specified in the OPP table. This is needed to guarantee correct behavior of the clock, especially with the higher clock/SPI bus frequencies.

2023-09-22spi: mchp-pci1xxxx: Annotate struct pci1xxxx_spi with __counted_byKees Cook
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct pci1xxxx_spi.

2023-09-18spi: bcm2835: reduce the abuse of the GPIO APIBartosz Golaszewski
Currently the bcm2835 SPI driver uses functions that are available exclusively to GPIO providers as a way to handle a platform quirk. Let's use a slightly better alternative that avoids poking around in GPIOLIB's internals and use GPIO lookup tables.

2023-09-15spi: dt-bindings: arm,pl022: Move child node properties to separate schemaRob Herring
In order to validate SPI peripherals, SPI controller-specific child node properties need to be in a separate schema, spi-peripheral-props.yaml, which SPI peripheral schemas reference.

2023-09-11spi: Use devm_clk_get_*() helper function toMark Brown
Merge series from Li Zetao <lizetao1@huawei.com>: Commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared and enabled clocks") provides a new helper function for prepared and enabled clocks when a driver keeps a clock prepared (or enabled) during the whole lifetime of the driver. So where drivers get clocks and enable them immediately, it can be combined into a single function devm_clk_get_*(). Moreover, the unprepare and disable function has been registered to devm_clk_state, and before devm_clk_state is released, the clocks will be unprepareed and disable, so it is unnecessary to unprepare and disable clocks explicitly when remove drivers or in the error handling path.
2023-09-11spi: switch to use modern name (part3)Mark Brown
Merge series from Yang Yingliang <yangyingliang@huawei.com>: I'm trying to rename the legacy name to modern name used in SPI drivers, this is part3 patchset. After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy named function devm_spi_alloc_master/spi_alloc_master() can be replaced. And also change other legacy name master/slave to modern name host/target or controller. Each patch compile test passed.

This func misses checking for platform_get_irq()'s call and may passes the negative error codes to request_irq(), which takes unsigned IRQ #, causing it to fail with -EINVAL, overriding an original error code.

Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared and enabled clocks"), devm_clk_get() and clk_prepare_enable() can now be replaced by devm_clk_get_enabled() when driver enables (and possibly prepares) the clocks for the whole lifetime of the device. Moreover, it is no longer necessary to unprepare and disable the clocks explicitly.

2023-09-11spidev: Simplify SPI_IOC_RD_MODE* cases in spidev_ioctl()Andy Shevchenko
The temporary variable tmp is not used outside of the SPI_IOC_RD_MODE* cases, hence we can optimize its use.

2023-09-11spidev: Switch to use spi_get_csgpiod()Andy Shevchenko
spidev_ioctl() checks if there is an SPI chip select is driven by GPIO. Instead of current code, we can call spi_get_csgpiod().

2023-09-11spidev: Decrease indentation level in spidev_ioctl() SPI_IOC_RD_MODE*Andy Shevchenko
Instead of defining a local controller variable inside an indented block, move the definition to the top of spidev_ioctl() and reuse it in the SPI_IOC_RD_MODE* and SPI_IOC_WR_MODE* cases. This drops unneeded indentation and reduces amount of LoCs.
