From 888162dabf64128603b12ac2d23236cf2086b7ef Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 10 Aug 2026 11:40:42 +0100 Subject: [PATCH 1/4] ASoC: cs35l56: Request IRQ in cs35l56_common_probe() Call cs35l56_irq_request() in cs35l56_common_probe() instead of calling it afterwards in the probe() for each bus type. Calling cs35l56_irq_request() in each bus probe() is a legacy of dealing with the oddities of the SoundWire framework. It's no longer serving any useful purpose to do it outside of the main cs35l56_common_probe().

Previously creation of the mapping was conditional on the use_domain_irq flag in the driver properties. But these are filled in after probe(), which meant it wasn't possible to request the IRQ during probe(). This was ok for MFD drivers where only children requested the IRQ. But for normal drivers it led to the non-standard behavior of having to defer requesting the IRQ until after probe().

This removes the local IRQ work function and the convoluted IRQ masking and pm_runtime management around it. We still need the local functions to mask/disable and unmask/enable the SoundWire interrupts because the devices handled by the cs35l56 driver don't have the generic mask bit for the ImpDef1 interrupt so masking and unmasking has to use a custom mask bit. cs35l56_sdw_remove() doesn't need to call cs35l56_disable_sdw_interrupts() now that there isn't a local work function to be flushed. It only masks the custom interrupt mask bit and the rest of the handler cleanup will be done the normal way by devm_free_irq() in cs35l56_remove(). Similar applies to cs35l56_sdw_system_suspend() - it is enough to write the custom mask bits. cs35l56_irq() doesn't need to be exported because cs35l56_sdw.c isn't calling it.
