rtc: sa1100/pxa: convert to run-time register mapping

2015-09-05T17:37:16+00:00

SA1100 and PXA differ only in register offsets which are currently
hardcoded in a machine specific header. Some arm64 platforms (PXA1928)
have this RTC block as well (and not the PXA270 variant).

Convert the driver to use ioremap and set the register offsets dynamically.
Since we are touching all the register accesses, convert them all to
readl_relaxed/writel_relaxed.

rtc: sa1100: prepare to share sa1100_rtc_ops

2015-09-05T17:37:15+00:00

Factor out the RTC initialization from the platform device specific
parts in order to share the RTC device ops with other drivers.
Specifically, it will be shared with rtc-pxa driver.

drivers/rtc/rtc-sa1100.c: make of_device_id array const

2014-06-06T23:08:09+00:00

Make of_device_id array const, because all OF functions handle
it as const.

rtc: rtc-sa1100: remove unnecessary platform_set_drvdata()

2013-07-03T23:07:51+00:00

The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound").  Thus, it is not needed to manually
clear the device driver data to NULL.

rtc: rtc-sa1100: use devm_*() functions

2013-04-30T01:28:38+00:00

Use devm_*() functions to make cleanup paths simpler.

rtc: rtc-sa1100: switch to using SIMPLE_DEV_PM_OPS

2013-04-30T01:28:32+00:00

Switch to using the SIMPLE_DEV_PM_OPS macro to declare the driver's
pm_ops.  It reduces code size.

drivers/rtc/rtc-sa1100.c: move clock enable/disable to probe/remove

2013-02-22T01:22:28+00:00

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.

drivers/rtc: use of_match_ptr() macro

2013-02-22T01:22:27+00:00

This eliminates having an #ifdef returning NULL for the case when OF is
disabled.  Maintains consistency in cases where OF is always selected.

Merge tag 'cleanup2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2012-03-30T01:02:10+00:00

Pull "ARM: cleanups of io includes" from Olof Johansson:
 "Rob Herring has done a sweeping change cleaning up all of the
  mach/io.h includes, moving some of the oft-repeated macros to a common
  location and removing a bunch of boiler plate.  This is another step
  closer to a common zImage for multiple platforms."

Fix up various fairly trivial conflicts ( removal vs changes
around it, tegra localtimer.o is *still* gone, yadda-yadda).

Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm

2012-03-28T01:17:02+00:00

Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.
