It has been agreed to make "system-power-controller" a standard property
and to drop the vendor-prefix that is currently used by several drivers.

Note that drivers that have used "<vendor>,system-power-controller" in a

Configure the RTC as system-power controller, which allows the system to
be powered off as well as woken up again on subsequent RTC alarms.

Note that the PMIC needs to be put in SLEEP (rather than OFF) mode to
maintain RTC power.  Specifically, this means that the PMIC
ti,pmic-shutdown-controller property must be left unset in order to be
able to wake up on RTC alarms.

Tested on BeagleBone Black (rev A5).

The lcd0 node for am437x-sk-evm.dts contains bad LCD timings, and while
they seem to work with a quick test, doing for example blank/unblank
will give you a black display.

This patch updates the timings to the 'typical' values from the LCD spec
sheet.

Also, the compatible string is completely bogus, as
"osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on
the board is a newhaven one. Update the compatible string to reflect
this. Note that this hasn't caused any issues, as the "panel-dpi"
matches the driver.

Caused by a copy & paste error. Note that even with
this bug AM437x SK display still works because GPIO
mux mode is always enabled. It's still wrong to mux
somebody else's pin.

Luckily ball D25 (offset 0x238 - gpio5_8) on AM437x
isn't used for anything.

While at that, also replace a pullup with a pulldown
as that gpio should be normally low, not high.

Commit f4d809ec55b6 ("ARM: dts: Fix gpmc timings for omap 2430sdp")
added GPMC timings for 2430sdp. This however broke the Ethernet
for some versions of u-boot using a different L3 clock frequency:

set_gpmc_timing_reg: GPMC error! CS5: cs_rd_off: 233 ns, 39 ticks > 31
omap-gpmc 6e000000.gpmc: failed to set gpmc timings for: ethernet

This is because the smsc91x timings from 1.1.4 u-boot overflow the
GPMC registers when booted with 1.1.3 version of u-boot.

Let's fix this issue by using the better timings from u-boot 1.1.3
as they also work on 1.1.4 and are faster.

Note that so far the attempts over the years to calculate the GPMC
timings on the SDP boards have failed probably because of the
unknown latencies added by the FPGA on the debug boards.

This will enable use of physical arch timers on rk3288, where each
core comes out of reset with a different virtual offset.  Using
physical timers will help with SMP booting on coreboot and older
u-boot and should also allow suspend-resume and cpu-hotplug to work on
all firmwares.

Firmware which does initialize the cpu registers properly at boot and
cpu-hotplug can remove this property from the device tree.

The old IOMMU device tree node is collapsed into the memory controller
node to more accurately describe the hardware. While this change is
incompatible, the IOMMU driver has never had any users so the change is

The fact that all supported boards use the same 33MHz crystal is a
co-incidence. The Zynq PS support a range of crystal freqs so the
hardcoded setting should be removed from the dtsi. Re-implement it

This prepares support for Zynq boards with different crystal
frequencies (e.g. the Digilent ZYBO).
