[ARM] pxa: allow dynamic enable/disable of GPIO wakeup for pxa{25x,27x}
Changes include:
1. rename MFP_LPM_WAKEUP_ENABLE into MFP_LPM_CAN_WAKEUP to indicate
the board capability of this pin to wakeup the system
2. add gpio_set_wake() and keypad_set_wake() to allow dynamically
enable/disable wakeup from GPIOs and keypad GPIO

dependency to the MFP configuration
3. pxa2xx_mfp_config() only gives early warning if MFP_LPM_CAN_WAKEUP
is set on incorrect pins
So that the GPIO's wakeup capability is now decided by the following:
a) processor's capability: (only those GPIOs which have dedicated
bits within PWER/PRER/PFER can wakeup the system), this is
initialized by pxa{25x,27x}_init_mfp()
b) board design decides:
- whether the pin is designed to wakeup the system (some of
the GPIOs are configured as other functions, which is not
intended to be a wakeup source), by OR'ing the pin config
with MFP_LPM_CAN_WAKEUP
- which edge the pin is designed to wakeup the system, this
may depends on external peripherals/connections, which is
totally board specific; this is indicated by MFP_LPM_EDGE_*

Note: there is no specific reason for some of the GPIOs to drive
high in low power mode as indicated by the above setting, those
bits are ignored, and the result is validated to work.

is now totally handled by pxa2xx_mfp_config():

[ARM] pxa: add MFP-alike pin configuration support for pxa{25x, 27x}
Pin configuration on pxa{25x,27x} has now separated from generic GPIO
into dedicated mfp-pxa2xx.c by this patch. The name "mfp" is borrowed
from pxa3xx and is used here to alert the difference between the two
concepts: pin configuration and generic GPIOs. A GPIO can be called
a "GPIO" _only_ when the corresponding pin is configured so.
A pin configuration on pxa{25x,27x} is composed of:
- alternate function selection (or pin mux as commonly called)
- low power state or sleep state
- wakeup enabling from low power mode
The following MFP_xxx bit definitions in mfp.h are re-used:
Selecting alternate function on pxa{25x, 27x} involves configuration
of GPIO direction register GPDRx, so a new bit and MFP_DIR_{IN, OUT}
are introduced. And pin configurations are defined by the following
two macros:
- MFP_CFG_IN : for input alternate functions
- MFP_CFG_OUT : for output alternate functions
Every configuration should provide a low power state if it configured
as output using MFP_CFG_OUT(). As a general guideline, the low power
state should be decided to minimize the overall power dissipation. As
an example, it is better to drive the pin as high level in low power
mode if the GPIO is configured as an active low chip select.
Pins configured as GPIO are defined by MFP_CFG_IN(). This is to avoid
side effects when it is firstly configured as output. The actual
direction of the GPIO is configured by gpio_direction_{input, output}
Wakeup enabling on pxa{25x, 27x} is actually GPIO based wakeup, thus
the device based enable_irq_wake() mechanism is not applicable here.
E.g. invoking enable_irq_wake() with a GPIO IRQ as in the following
code to enable OTG wakeup is by no means portable and intuitive, and
it is valid _only_ when GPIO35 is configured as USB_P2_1:
enable_irq_wake( gpio_to_irq(35) );
To make things worse, not every GPIO is able to wakeup the system.
Only a small number of them can, on either rising or falling edge,
or when level is high (for keypad GPIOs).
Thus, another new bit is introduced to indicate that the GPIO will
wakeup the system:
- MFP_LPM_WAKEUP_ENABLE
The following macros can be used in platform code, and be OR'ed to
the GPIO configuration to enable its wakeup:

registers are already configured on pxa{25x,27x} while returns
0 always on pxa3xx
2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign-

This makes the code better organized and simplified a bit. The change
will lose a bit of performance when performing IRQ ack/mask/unmask,but
that's not too much after checking the result binary.
This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by
carefully not to access those pxa{27x,3xx} specific registers, this
is done by keeping an internal IRQ number variable. The pxa-regs.h
is also modified so registers for IRQ > PXA_IRQ(31) are made public
even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake)
The incorrect assumption in the original code that internal irq starts
from 0 is also corrected by comparing with PXA_IRQ(0).
"struct sys_device" for the IRQ are reduced into one single device on
pxa{27x,3xx}.

This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89
aka "[NET]: Do not allocate unneeded memory for dev->priv alignment."
It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST
removal.
For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size"
was also 2048 bytes, but allocator with debugging options turned on started
giving out !32-byte aligned memory resulting in redzones overwrites.
Patch does small optimization in ->priv'less case: bumping size to next
32-byte boundary was always done to ensure ->priv will also be aligned.
But, no ->priv, no need to do that.
