Both callers of spi_stop_queue() (i.e. spi_destroy_queue() and spi_controller_suspend()) already emit an error message if spi_stop_queue() fails. Another warning in this case isn't helpful, so drop it. Signed-off-by:

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. Move the arm,pl022 child properties to their own schema file and add a $ref in spi-peripheral-props.yaml. Signed-off-by:

Merge series from Li Zetao <lizetao1@huawei.com>: Commit 7ef9651e ("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.

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.

Add runtime pm support to cadence-qspi driver, this allows the driver to suspend whenever it's is not actively being used thus reducing active power consumed by the system. Also, with the use of devm_pm_runtime_enable we no longer need the fallback probe_pm_failed that used to pm_runtime_disable Co-developed-by:

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. Fixes: dc4dc360 ("spi: tegra: add spi driver for SLINK controller") Signed-off-by:
