The patches fix some bugs
1. pwm-pxa driver is shared by ARCH_PXA and ARCH_MMP
2. use module_platform_driver for driver register
The patches also add device tree support for pwm.
Chao Xie (3):
pwm: pxa: ARCH_MMP share same pwm driver with ARCH_PXA
pwm: pxa: use module_platform_driver
the pwm driver is not only used by ARCH_PXA but also ARCH_MMP

The original sa1100_rtc_open/sa1100_rtc_release will be called
when the /dev/rtc0 is opened or closed.
In fact, these two functions will enable/disable the clock.
Disabling clock will make rtc not work.
So only enable/disable clock when probe/remove the device.

the pxa95x rtc need access PBSR register before write to

hi
When develop the clk drivers for SOCs based on common clock framework.
I met a issue.
For example there is a uart device, it's function clock comes from a
divider, and the divider's parent is a mux. It means
MUX -- DIV -- UART
As we know that UART can work at low baudrate for a terminal,
indepent of open/close the
rtc device.
So only enable clock and register the irqs when probe the device,
and disable clock and unregister the irqs when remove the device.

Some controller need software to initialize PHY before add
host controller, and shut down PHY after remove host controller.
Add the generic code for these controllers so they do not need
do it in its own host controller driver.

88pm800 has two addtional pages - power and gpadc.
The address of the pages depends on the address of 88pm800.
So do not need pass the address of the power and gpadc in
platform data.

Separate the devices initialization into different functions.
It makes the probe function clearly.

/88pm805: remove IRQF_TRIGGER_FALLING flag
Other patches are new.
Chao Xie (7):
mfd: 88pm80x: fix driver name for 88pm800 and 88pm805
mfd: 88pm800: fix for mask_invert
mfd: 88pm800: remove the power and gpadc page addr from platform data
mfd: 88pm800: fixes error handling for sub pages
Change the chip id definition and detection.
It brings the benefits
1. do not need add PM800_CHIP_XXX for the coming revision.
2. do not need pass driver_data in i2c_device_id because we
can distinguish the chips by CHIP_ID register.
