2023-09-26spi: omap2-mcspi: Fix hardcoded reference clockVaishnav Achath1-11/+20
A hardcoded reference clock of 48 MHz is used to calculate the clock divisor values, but the reference clock frequency can be different across devices and can be configured which can cause a mismatch between the reported frequency and actual SPI clock frequency observed. Fix this by fetching the clock rate from the clock provider and falling back to hardcoded reference only if the clock is not supplied.

2023-09-26spi: qup: Allow scaling power domains andMark Brown2-1/+62
Merge series from Stephan Gerhold <[email protected]>: Make it possible to scale performance states of the power domain and interconnect of the SPI QUP controller in relation to the selected SPI speed / core clock. This is done separately by: - Parsing the OPP table from the device tree for performance state votes of the power domain - Voting for the necessary bandwidth on the interconnect path to DRAM
2023-09-25spi: at91-usart: Remove some dead codeChristophe JAILLET1-18/+4
dma_request_chan() does not return NULL. It returns a valid pointer or an error pointer. So, some dead code can be removed. The IS_ERR_OR_NULL() in the error handling path are still needed, because the error handling path is common to the whole function and the ctlr->dma_xx are NULL when at91_usart_spi_configure_dma() is called.

2023-09-25spi: qup: Vote for interconnect bandwidth to DRAMStephan Gerhold1-0/+38
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. The requested peak bandwidth is dependent on the SPI core/bus clock so that the bandwidth scales together with the selected SPI speed. To avoid sending votes too often the bandwidth is always requested when a DMA transfer starts, but dropped only on runtime suspend. Runtime suspend should only happen if no transfer is active. After resumption we can defer the next vote until the first DMA transfer actually happens.

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.

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).

2023-09-11spi: Use devm_clk_get_*() helper function toMark Brown25-413/+88
Merge series from Li Zetao <[email protected]>: 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.

And also change other legacy name master/slave to modern name host/target or controller. Each patch compile test passed.

2023-09-11spidev: Simplify SPI_IOC_RD_MODE* cases in spidev_ioctl()Andy Shevchenko1-5/+3
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 Shevchenko1-4/+2
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 Shevchenko1-8/+6
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.
