03fbdb15c1 [ARM] 5519/1: amba probe: pass "struct amba_id *" instead of void *
The second argument of the probe method points to the amba_id
structure, so it's better passed with the correct type. None of the
current in-tree drivers uses the pointer, so they have only been
checked for a clean compile.

Change suggested by Russell King.

f993004d73 rtc: rtc-twl4030 don't mask alarm interrupts on suspend
This patch enables the alarm interrupt of TWL4030 RTC to wake up the
system from suspend. You can test this patch with following command.

# echo +10 > /sys/class/rtc/rtc0/wakealarm; echo mem > /sys/power/state;

6d029b6451 rtc-cmos: fix printk output
With no IRQ available/defined, RTC-CMOS driver prints something like:
	rtc0: alarms up to one no, y3k, 114 bytes nvram
                              ^^^^
I guess the following is a bit easier to understand:
	rtc0: no alarms, y3k, 114 bytes nvram

063adc7502 rtc: rtc-sh: clock framework support.
This adds clock framework support to the rtc-sh driver. With this in

placing it in the always enabled state.

99b7623380 proc 2/2: remove struct proc_dir_entry::owner
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
as correctly noted at bug #12454. Someone can lookup entry with NULL
->owner, thus not pinning enything, and release it later resulting
in module refcount underflow.

We can keep ->owner and supply it at registration time like ->proc_fops
and ->data.

But this leaves ->owner as easy-manipulative field (just one C assignment)
and somebody will forget to unpin previous/pin current module when
switching ->owner. ->proc_fops is declared as "const" which should give
some thoughts.

->read_proc/->write_proc were just fixed to not require ->owner for
protection.

rmmod'ed directories will be empty and return "." and ".." -- no harm.
And directories with tricky enough readdir and lookup shouldn't be modular.
We definitely don't want such modular code.

Removing ->owner will also make PDE smaller.

So, let's nuke it.

Kudos to Jeff Layton for reminding about this, let's say, oversight.

5bf3df3f00 [ARM] pxa: separate definitions from pxa-regs.h and remove it finally
The remaining registers are separated into:

   - <mach/regs-ost.h>
   - <mach/regs-rtc.h>
   - <mach/regs-intc.h>

and then we can remove pxa-regs.h completely. Instead of #include this
file, let's:

1. include the specific <mach/regs-*.h> with care (if that's absolutely
   necessary)

2. define the registers in the driver, make cleanly defined API to expose
   the register access to external with sufficient reason

5e084a1586 rtc: sh-rtc: Add Single IRQ Support
Add support for single IRQ hardware to the sh-rtc driver.

This is useful for processors with limited interrupt masking
support such as sh7750 and sh7780. With this patch in place we
can add logic to the intc code that merges all RTC vectors into
a single linux interrupt with proper masking/unmasking support.

Specify a single IRQ in the platform data to use this new shared
IRQ feature. Separate Periodic/Carry/Alarm IRQs are still supported.

c318c7ac49 rtc: t reaches -1, tested 0
With a postfix decrement t will reach -1 rather than 0, so neither the
warning nor the `goto error_out' will occur.

afd8d0f940 rtc: rtc-dm355evm driver
Simple RTC driver for the MSP430 firmware on the DM355 EVM board.  Other
than not supporting atomic reads/writes of all four bytes, this is
reasonable as a basic no-alarm RTC.
