spi: Remove redundant pm_runtime_mark_last_busy() calls

2025-07-04T23:50:32Z

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

spi: spi-mem: Introduce a default ->exec_op() debug log

2025-03-20T12:37:11Z

Many spi-mem controller drivers have a very similar debug log at the beginning of their ->exec_op() callback implementation. This debug log is effectively useful, so let's create one that is complete and concise enough, so developers no longer need to write their own. The verbosity being high, VERBOSE_DEBUG will be required in this case. Remove the debug log from individual drivers and propose a common one.

spi: zynqmp-gqspi: Always acknowledge interrupts

2025-02-03T00:40:36Z

RXEMPTY can cause an IRQ, even though we may not do anything about it (such as if we are waiting for more received data). We must still handle these IRQs because we can tell they were caused by the device.

spi: zynqmp-gqspi: Clean up fillgenfifo

2025-02-03T00:40:35Z

This function does a lot more work (assigning things multiple times, masking unnecessarily, comparing to zero, using superfluous parentheses) than it needs to. This makes it difficult to understand and modify. Clean it up. No functional change intended.

DMA is enabled and disabled several times in the driver. Add some helper functions for this task. Signed-off-by: Sean Anderson Link: https://patch.msgid.link/20250116224130.2684544-4-sean.anderson@linux.dev Signed-off-by: Mark Brown

spi: zynqmp-gqspi: Support per spi-mem operation frequency switches

2025-01-09T20:16:38Z

Every ->exec_op() call correctly configures the spi bus speed to the maximum allowed frequency for the memory using the constant spi default parameter. Since we can now have per-operation constraints, let's use the value that comes from the spi-mem operation structure instead. In case there is no specific limitation for this operation, the default spi device value will be given anyway. The per-operation frequency capability is thus advertised to the spi-mem core.

spi: zynqmp-gqspi: Undo runtime PM changes at driver exit time

2024-11-01T14:48:54Z

It's important to undo pm_runtime_use_autosuspend() with pm_runtime_dont_use_autosuspend() at driver exit time. So, call pm_runtime_dont_use_autosuspend() at driver exit time to fix it.

spi: Switch back to struct platform_driver::remove()

2024-09-29T23:12:23Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/spi to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. The change for the spi-npcm-fiu stands out in the diffstat because the inconsistent formatting style of the platform_driver initializer is fixed to match the other struct initializer in the file.
