The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay. So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII. This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.Signed-off-by: Andy Fleming

The Vitesse PHY on the 8641D needs to be set up with internal delay to
work in RGMII mode. So we add skew when it is set to RGMII_ID mode.Signed-off-by: Andy Fleming

The TSEC/eTSEC automatically detect their PHY interface type, unless
the type is RGMII-ID (RGMII with internal delay). In that situation,
it just detects RGMII. In order to fix this, we need to pass in rgmii-id
if that is the connection type.Signed-off-by: Andy Fleming
-
The Vitesse 824x PHY doesn't allow an interrupt to be cleared if
the mask bit for that interrupt isn't set. This means that the PHY
Lib's order of handling interrupts (disable, then clear) breaks on this
PHY. However, clearing then disabling the interrupt opens up the code
for a silly race condition. So rather than change the PHY Lib, we change
the Vitesse driver so it always clears interrupts before disabling them.
Further, the ack function only clears the interrupt if interrupts are
enabled.Signed-off-by: Andy Fleming

The STK1000 uses pullups on the MDIO lines to the PHY, but they are
too weak. This causes the PHY layer to detect PHYs on all possible MII
addresses. Mask out all but the correct address to prevent this from
happening.Signed-off-by: Haavard Skinnemoen

These functions depend on "result" being initalized to 0, but "result"
is not included as an input constraint to the inline assembly block
following its initialization, only as an output constraint. Thus gcc
thinks it doesn't need to initialize it, so result ends up undefined
if the "unless" condition is true.This fixes an oops in sunrpc where the faulty atomics caused
rpciod_up() to not start the workqueue as it should.Signed-off-by: Haavard Skinnemoen

Signed-off-by: Haavard Skinnemoen -
If we let unaligned word loads bypass the generic unaligned handling,
gcc may combine it with a swap.b instruction and turn it into a ldwsp
instruction, which does not work with unaligned addresses.Revert the optimization to prevent the RNDIS driver from crashing.
Hopefully we'll figure something out later (it may be better to do the
optimization in gcc.)Signed-off-by: Haavard Skinnemoen

This adds some STK1002-specific config options covering the jumper settings,
so the kernel can automatically be configured to include the relevant devices.One of them replaces the previous internal SW2_DEFAULT setting; SPI config
is affected by two of the jumpers; and a fourth one switches between LCD and
the second Ethernet connector. (There's more that to be done.)Signed-off-by: David Brownell

This patch enables CPU frequency scaling for AT32AP devices. This will
enable the CPU to scale between the speed of the high speed bus and
the master clock and thus save some power.The patch also adds a parent to cpu_clk and a cpu_clk_set_rate to
enable changing the CPU clock divider in a sane way.The driver does not check if the given rate is 0, thus resulting in a
div by 0. I think this check should be go into the clk_set_rate
framework, and not here.Tested on AT32AP7000/ATSTK1000.
Hardware documentation can be found in the AT32AP7000 datasheet.

Split the SM platform device into separate platform devices for PM,
RTC, WDT and EIC. This is more correct according to the documentation
and allows us to simplify the code a little.Also turn the EIC driver into a real platform driver.

Use a more conventional implementation for unaligned access, and include
an AT32AP-specific optimization: the CPU will handle unaligned words.The result is always faster and smaller for 8, 16, and 32 bit values.
For 64 bit quantities, it's presumably larger.Signed-off-by: David Brownell

There exists at least one card, Trident TVGA8900CL (BIOS dated 1992/9/8)
which clobbers DS when "scrolling in an SVGA text mode of more than
800x600 pixels." Although we are extremely unlikely to run into that
situation, it is cheap insurance to save and restore DS, and it only adds
a grand total of 50 bytes to the total output.Pointed out by Etienne Lorrain.

If the user has asked for the vertical height registers to be recomputed
by setting bit 15 in the video mode number, we do so without clearing the
Protect bit in the Vertical Retrace Register before setting the Overflow
register. As a result, if the VGA BIOS had set the Protect bit, the
write to the Overflow register will be dropped, and bits [9:8] of the
vertical height will be left unchanged.This is a bug imported from the assembly version of this code. It was
pointed out by Etienne Lorrain.Cc: Etienne Lorrain

Fix incorrect assembly constraints. In particular, fix memory
constraints used inside push..pop, which can cause invalid operation
since gcc may generate %esp-relative references.Additionally:
outl() should have "dN" not "dn".
query_mca() shouldn't listen 16/32-bit registers in an 8-bit only
context.has_eflag(): the "mask" is only used well after both the stack pointer
and the output registers have been touched; this requires the output
registers to be earlyclobbers (=&) and the input to exclude memory (so
"ri", not "g").Thanks to Etienne Lorrain and Chuck Ebbert for prompting this review.
