spi: spi-zynq-qspi: add spi-mem to driver kconfig dependencies

2023-11-20T10:57:25Z

[ Upstream commit c2ded280a4b1b7bd93e53670528504be08d24967 ] Zynq QSPI driver has been converted to use spi-mem framework so add spi-mem to driver kconfig dependencies.

spi: omap2-mcspi: Fix hardcoded reference clock

2023-11-20T10:56:58Z

[ Upstream commit 2d9f4877988f64f0f336983de65c365b6a7debfb ] 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.

spi: omap2-mcspi: remove redundant dev_err_probe()

[ Upstream commit 142c61a5fddeb755c420cb2e23b4bc0c0901308f ] When platform_get_irq() is called, the error message has been printed, so it need not to call dev_err_probe() to print error, we remove the redundant platform_get_irq().

spi: nxp-fspi: use the correct ioremap function

2023-11-20T10:56:56Z

[ Upstream commit c3aa5cb264a38ae9bbcce32abca4c155af0456df ] 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.

spi: tegra: Fix missing IRQ check in tegra_slink_probe()

2023-11-20T10:56:54Z

[ Upstream commit eb9913b511f10968a02cfa5329a896855dd152a3 ] 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. Fix this by stop calling request_irq() with invalid IRQ #s.

spi: zynqmp-gqspi: fix clock imbalance on probe failure

commit 1527b076ae2cb6a9c590a02725ed39399fcad1cf upstream. Make sure that the device is not runtime suspended before explicitly disabling the clocks on probe failure and on driver unbind to avoid a clock enable-count imbalance.

spi: stm32: add a delay before SPI disable

[ Upstream commit 6de8a70c84ee0586fdde4e671626b9caca6aed74 ] As explained in errata sheet, in section "2.14.5 Truncation of SPI output signals after EOT event": On STM32MP1x, EOT interrupt can be thrown before the true end of communication. So we add a delay of a half period to wait the real end of the transmission.
