Wolfram Sang 97f902b7be rtc: rtc-ds1307 add ds3231
Add ds3231 variant.  For that, the BBSQI bit position was changed from a
simple define into a lookup-array as it differs.  This also removes
writing to an unused bit in case of the ds1337.

Torsten Ertbjerg Rasmussen 3a72970054 rtc: rtc-ds1742 nvram attribute fix
The RTC driver for ds1742 / ds1743 uses a static nvram attribute.  This
patch replaces this static attribute with one nvram attribute for each
ds174x registered.

The nvram size is not the same for all types of ds174x.  The nvram size is
accessible as the file size of the nvram attribute in sysfs.  With only a
single nvram attribute, this file size will be incorrect if more than one
type of ds174x is present on a system.  See the comment in the removed
code below.

This patch have been tested with linux-2.6.28 and linux-2.6.29-rc5/6 on a
custom board with one ds1743.

Linus Walleij dc890c2dcd [ARM] 5544/1: Trust PrimeCell resource sizes
I found the PrimeCell/AMBA Bus drivers distrusting the resource
passed in as part of the struct amba_device abstraction. This
patch removes all hard coded resource sizes found in the PrimeCell
drivers and move the responsibility of this definition back to
the platform/board device definition, which already exist and
appear to be correct for all in-tree users of these drivers.
We do this using the resource_size() inline function which was
also replicated in the only driver using the resource size, so
that has been changed too. The KMI_SIZE was left in kmi.h in case
someone likes it. Test-compiled against Versatile and Integrator
defconfigs, seems to work but I don't posess these boards and
cannot test them.

Alessandro Rubini 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.

Hartley Sweeten 38f7b009a6 [ARM] 5452/1: ep93x: rtc: use ioremap'ed addresses
Update the rtc-ep93xx driver to use ioremap'ed addresses.

This removes the dependency on <mach/hardware.h> and properly
reports the memory addresses used by the driver in /proc/iomem.

In addition, ep93xx_rtc_init() is updated to use
platform_driver_probe() instead of platform_driver_register().

Also, the device_create_file() calls are now properly checked for
error conditions.  The created sysfs files are also now removed
when the driver is removed.

The version number for the driver has been bumped at the request
of Alessandro Zummo.

Andrew Morton 78d89ef40c rtc: convert LEAP_YEAR into an inline
- the LEAP_YEAR macro is buggy - it references its arg multiple times.
  Fix this by turning it into a C function.

- give it a more approriate name

- Move it to rtc.h so that other .c files can use it, instead of copying it.

Alexey Dobriyan 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.

Nicolas Pitre 9d1d4f9eab [ARM] Kirkwood: fail the probe if internal RTC does not work
Having a RTC that doesn't maintain proper time across a reboot is one

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

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.

They were left over from the legacy style I2C driver, which had to defend

Also fix a minor glitch in the alarm support: DS1307 chips don't have
alarms, so name those methods after one of the chips which actually *do*
have alarms (DS1337).

Robert Jarzmik dc9443688e rtc: driver for pxa27x and pxa3xx SoC
With PXA27x and above, a new RTC hardware block was added in addition to
the legacy one which is also found on the SA1100 SOC family.  This second
RTC block is called "wristwatch" and "periodic interrupt" and works
independently from the other RTC block.

The driver offers provides :
 - a 1Hz ticking clock
 - a periodic alarm, in the 1Hz to 1000Hz range
 - a one shot alarm

Move the power of 2 check on frequencies down into individual rtc drivers

This is to allow for non power of 2 real time clock periodic interrupts
such as those on the pxa27x to be found in the new pxa27x-rtc driver

Anton Vorontsov 2fac6674dd rtc: bunch of drivers: fix 'no irq' case handing
This patch fixes a bunch of irq checking misuses.  Most drivers were
getting irq via platform_get_irq(), which returns -ENXIO or r->start.

rtc-cmos.c is special.  It is using PNP and platform bindings.  Hopefully
nobody is using PNP IRQ 0 for RTC.  So the changes should be safe.

rtc-sh.c is using platform_get_irq, but was storing a result into an
unsigned type, then was checking for < 0.  This is fixed now.

Alessandro Zummo 099e657625 rtc: add alarm/update irq interfaces
Add standard interfaces for alarm/update irqs enabling.  Drivers are no
more required to implement equivalent ioctl code as rtc-dev will provide
it.

UIE emulation should now be handled correctly and will work even for those
RTC drivers who cannot be configured to do both UIE and AIE.

As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more
a constant on PXA when multiple processors and platforms are
selected, change TIMER_FREQ in rtc-sa1100.c into a variable.

Since the code to decide the clock tick rate is re-used from
timer.c, introduce a common get_clock_tick_rate() for this.

Stelian Pop 7be90a6ba9 [ARM] 5319/1: AT91: support AT91CAP9 revC CPUs
The AT91CAP9 revC CPU has a few differences over the previous,
revB CPU which was distributed in small quantities only (revA was
an internal Atmel product only).

This patch adds the detection routines to recognize the different
AT91CAP9 revisions (based on the PMC subsystem version number), and
uses them to:
	- activate a workaround for the external interrupts levels
	  (on revB CPUs)
	- set the UDPHS_BYPASS bit (on revB CPUs)
	- set AT91_GPBR register address to the correct offset
	  (0xfffffd50 on revB, 0xfffffd60 on revC)

For debugging usage, the CPU revision can be found in /proc/cpuinfo
on the 'Revision' line.

This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch)
where it has been tested for the last 6 months.
