Stephen Warren [Fri, 2 Dec 2011 22:08:40 +0000 (15:08 -0700)]
ASoC: WM8903: Get default irq_active_low from IRQ controller

If the WM8903 is hooked up to an interrupt, set the irq_active_low flag
in the default platform data based on the IRQ's IRQ_TYPE. Map IRQ_TYPE_NONE
(a lack of explicit configuration/restriction) to irq_active_low = false;
the previous default.

This code is mainly added to support device tree interrupt bindings,
although will work perfectly well in a non device tree system too.

Any interrupt controller that supports only a single IRQ_TYPE could
set each IRQ's type based on that restriction. This applies equally
with and without device tree. To cater for interrupt controllers
that don't do this, for which irqd_get_trigger_type() will return
IRQ_TYPE_NONE, the platform data irq_active_low field may be used
in systems that don't use device tree.

With device tree, every IRQ must have some IRQ_TYPE set.

Controllers that support DT and multiple IRQ_TYPEs must define the
interrupts property (as used in interrupt source nodes) such that it
defines the IRQ_TYPE to use. When the core DT setup code initializes
wm8903->irq, the interrupts property will be parsed, and as a side-
effect, set the IRQ's IRQ_TYPE for the WM8903 probe() function to read.

Controllers that support DT and a single IRQ_TYPE could arrange to
set the IRQ_TYPE somehow during their initialization, or hard-code
it during the processing of the child interrupts property.

ASoC: WM8903: Remove conditionals checking pdata != NULL

The pdata pointer is now always valid. Remove any conditions that check
its validity.

This patch is mostly just removing an indentation level. One variable had
to be moved due to the removal of a scope, and one comment was split into
two. Viewing the patch with git show/diff -b will show that it's actually
very small.

Note that WM8903_MIC_BIAS_CONTROL_0 is now written unconditionally,
whereas it used to be written only if pdata was supplied. Since
defpdata.micdet_cfg = 0, this unconditional write simply echos the HW
defaults in the case where pdata is not supplied.

13 years agoASoC: WM8903: Fix platform data gpio_cfg confusion
Stephen Warren [Fri, 2 Dec 2011 22:08:37 +0000 (15:08 -0700)]
ASoC: WM8903: Fix platform data gpio_cfg confusion

wm8903_platform_data.gpio_cfg[] was intended to be interpreted as follows:
0:       Don't touch this GPIO's configuration register
1..7fff: Write that value to the GPIO's configuration register
8000:    Write zero to the GPIO's configuration register
other:   Undefined (invalid)

The rationale is that platform data is usually global data, and a value of
zero means that the field wasn't explicitly set to anything (e.g. because
the field was new to the pdata type, and existing users weren't update to
initialize it) and hence the value zero should be ignored. 0x8000 is an
explicit way to get 0 in the register.

The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs
through gpiolib", where the behaviour was changed due to my lack of
awareness of the above rationale.

This patch reverts to the intended behaviour, and updates all in-tree users
to use the correct scheme. This also makes WM8903 consistent with other
devices that use a similar scheme.

WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that
its name accurately reflects its purpose.

It has been pointed out previously, that the firmware subsystem is not the right
place for the SigmaDSP firmware loader. Furthermore the SigmaDSP is currently
only used in audio products and we are aiming for better integration into the
ASoC framework in the future, with support for ALSA controls for firmware
parameters and support dynamic power management as well. So the natural choice
for the SigmaDSP firmware loader is the ASoC subsystem.
