Now that the mfd is using the register map cache there's no need for the CODEC driver to do any register cache management or any funny dances to interact with the other drivers using the device so just remove the cache initialisation and volatility information.

Currently SND_SOC_JZ4740_CODEC depends on SOC_JZ4740 but SOC_JZ4740 is not defined in any Kconfig. Thus the codec driver will not be built when select "Build all ASoC CODEC drivers". (Unless it is selected by SND_JZ4740_SOC_QI_LB60). Remove the dependency with SOC_JZ4740, then this code driver can be built when select "Build all ASoC CODEC drivers".

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.

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. Based on work by John Bonesio, but significantly reworked since then.

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 7cfe5617 "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.
