RS800480T-7X0WQ and the timings have been extracted from Technologic
Systems' tree.

Previously, the device tree mapped the FPGA like any other IPs inside
the SoC, but it is actually mapped through the WEIM (Wireless External
Interface Module). This patch updates the device tree to make use of it.
About the timings: in the image provided by the manufacturer, only
CS0GCR1 is changed. The other values are the default ones, but the WEIM
bindings expect them to be all explicitly set in the device tree, so I
just put the default values in the dt.

This device tree adds support for TS-4800 by Technologic Systems. This
board is based on MX51-babbage, but there are some subtle differences in
the pins used, and there is an additional FPGA that is memory-mapped.

This has been moved to the reg property where it belongs for quite some

Currently it is not possible to have HDMI and LVDS working simultaneously,
because both ports try to use PLL5.
Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be

Linux on Vybrid used several different L2 latencies so far, none
of them seem to be the right ones. According to the application note
AN4947 ("Understanding Vybrid Architecture"), the tag portion runs
on CPU clock and is inside the L2 cache controller, whereas the data
portion is stored in the external SRAM running on platform clock.
Hence it is likely that the correct value requires a higher data
latency then tag latency.
These are the values which have been used so far:
- The mainline values:
arm,data-latency = <1 1 1>;
arm,tag-latency = <2 2 2>;
Those values have lead to problems on higher clocks. They look
like a poor translation from the reset values (missing +1 offset
and a mix up between tag/latency values).
- The Linux 3.0 (SoC vendor BSP) values (converted to DT notation):
arm,data-latency = <4 2 3>
arm,tag-latency = <4 2 3>
The cache initialization function along with the value matches the
i.MX6 code from the same kernel, so it seems that those values have
just been copied.
- The Colibri values:
arm,data-latency = <2 1 2>;
arm,tag-latency = <3 2 3>;
Those were a mix between the values of the Linux 3.0 based BSP and
the mainline values above.
- The SoC Reset values (converted to DT notation):
arm,data-latency = <3 3 3>;
arm,tag-latency = <2 2 2>;
So far there is no official statement on what the correct values are.
See also the related Freescale community thread:
https://community.freescale.com/message/579785#579785
For now, the reset values seem to be the best bet. Remove all other
"bogus" values and use the reset value on vf610.dtsi level.

So far, only the bus clock has been assigned, but in reality the
SAI IP has for clock inputs. The driver has been updated to
make use of the additional clock inputs by c3ecef21c3 ("ASoC:
fsl_sai: add sai master mode support"). Due to a bug in the
clock tree, the audio clock has been enabled none the less by
the specified bus clock (see "ARM: imx: clk-vf610: fix SAI
clock tree"), which made master mode even without the proper
clock assigned working.
This patch completes the clock definition for SAI2. On Vybrid,
only two MCLK out of the four options are available (the first
being the bus clock itself). See chapter 8.10.1.2.3 of the
Vybrid Reference manual ("SAI transmitter and receiver options
for MCLK selection"). Note: The audio clocks are only required
in master mode.

GPC irq domain is a child domain of GIC, now all of platform irqs
are inside GPC domain, during the module populate, all devices irq
should have correct type setting in GIC, however, there is no
.irq_set_type callback setting in GPC, so the irq_set_type will be
skipped and cause all irqs' type in /proc/interrupt are "edge" which
mismatch with irq type setting in dtb file. Since GPC has no irq
type setting, so just tell kernel to use irq_chip_set_type_parent.

Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS
