misc: update maintainer email address and description for atmel-ssc

2022-08-03T09:03:03+00:00

I have changed my overall maintainer email address to the samfundet.no
domain, hence update the atmel-ssc module to reflect that.

Also remove the AVR32 reference, since the AVR32 architecture no longer
exist in the Linux kernel.

misc: atmel-ssc: Fix IRQ check in ssc_probe

2022-06-10T13:29:56+00:00

platform_get_irq() returns negative error number instead 0 on failure.
And the doc of platform_get_irq() provides a usage example:

    int irq = platform_get_irq(pdev, 0);
    if (irq < 0)
        return irq;

Fix the check of return value to catch errors correctly.

misc: atmel-ssc: lock with mutex instead of spinlock

2020-06-29T17:10:51+00:00

Uninterruptible context is not needed in the driver and causes lockdep
warning because of mutex taken in of_alias_get_id(). Convert the lock to
mutex to avoid the issue.

misc: atmel-ssc: Fix section annotation on atmel_ssc_get_driver_data

2018-11-11T17:13:19+00:00

After building the kernel with Clang, the following section mismatch
warning appears:

WARNING: vmlinux.o(.text+0x3bf19a6): Section mismatch in reference from
the function ssc_probe() to the function
.init.text:atmel_ssc_get_driver_data()
The function ssc_probe() references
the function __init atmel_ssc_get_driver_data().
This is often because ssc_probe lacks a __init
annotation or the annotation of atmel_ssc_get_driver_data is wrong.

Remove __init from atmel_ssc_get_driver_data to get rid of the mismatch.

misc: atmel-ssc: register as sound DAI if #sound-dai-cells is present

2016-12-15T12:13:31+00:00

The SSC is currently not usable with the ASoC simple-audio-card, as
every SSC audio user has to build a platform driver that may do as
little as calling atmel_ssc_set_audio/atmel_ssc_put_audio (which
allocates the SSC and registers a DAI with the ASoC subsystem).

So, have that happen automatically, if the #sound-dai-cells property
is present in devicetree, which it has to be anyway for simple audio
card to work.
