As the wm8994 series of devices are now very mature make the current
behaviour of the devices the default behaviour, any future revisions are
likely to have only minor updates.

Fix build errors when CONFIG_OF is not enabled by including
<linux/of.h> (needs to be added in any case).
An alternative fix could be to make the driver depend on OF.

Historically, a driver would have to decide whether it required
a Linear or Legacy IRQ domain when registering one. This can end
up as quite a lot of code. A new Simple call now exists which
simplifies this process. Let's make use of it here.

I got below build warning while compiling this driver.
It's obviously RC5T583_MAX_INTERRUPT_MASK_REGS is 9 but irq_en_add
array only has 8 elements.

drivers/mfd/rc5t583-irq.c: In function 'rc5t583_irq_init':

Since the number of interrupt enable registers is 8, this patch adds
define for RC5T583_MAX_INTERRUPT_EN_REGS to fix this bug.

Previously a generic binding 'i2c-client-wake' was created which
enabled I2C devices to register themselves as wake-up devices.
This binding was later over-thrown by 'wakeup-source'. The STMPE
driver was fixed-up, but the document was neglected. This patch
aims to rectify that.

At every boot of an (outdated) laptop lpc_ich prints an error:
lpc_ich 0000:00:1f.0: I/O space for GPIO uninitialized
But if one looks at lpc_ich's probe function one notices that the code
only cares if both lpc_ich_init_wdt() and lpc_ich_init_gpio() fail to
add any cells. So stop treating the failure to add a single cell as an
error. Those messages can be printed at notice level. And then only warn
if no cells were added.

The older southbridges supported by the lpc_ich driver do not
provide memory-mapped space of the root complex. The driver
correctly avoids computing the iomem address in this case, yet
submits a zeroed resource request anyway (via mfd_add_devices()).
Remove the iomem resource from the resource array submitted to the
mfd core for the older southbridges.

The twl6030-pwm driver is going to be deleted since it was only able to
control the Charging indicator LED on the twl6030 PMIC.
The new set of drivers are going to provide support for both PWMs and PWM
driven LED outputs on TWL4030 and TWL6030 PMICs.
The twl-pwm driver will handle the PWMs (2 instance) while the twl-pwmled
driver is to control the two LED instance on TWL4030 and to charging
indicator LED (1 instance) on TWL6030.

For Realtek card reader, internal regsiter SD_CFG2 should be configured
before transferring data.
The default value of SD_CFG2 is proper for writing data. But for reading
sequence, the timing is not good enough. So in some extreme circumstance,
card reader may sample the response data from the card as good even if
the data is wrong. And this will cause the bad consequence.
In the prior version, the value of this register has been calculated,
but forgotten to write back to the internal register.
