NXP LPC32xx SoC has one USB OTG controller, which is supposed to work
with an external phy (default is NXP ISP1301).
Practically the USB controller contains 5 subdevices:
- host controller 0x3102 0000 -- 0x3102 00FF
- OTG controller 0x3102 0100 -- 0x3102 01FF
- device controller 0x3102 0200 -- 0x3102 02FF
- I2C controller 0x3102 0300 -- 0x3102 03FF
- clock controller 0x3102 0F00 -- 0x3102 0FFF
The USB controller can be considered as a "bus", because the
subdevices above are relatively independent, for example I2C
controller is the same as other two general purpose I2C controllers
found on SoC.
The change is not intended to modify any logic, but it rearranges
existing device nodes, in future it is planned to add a USB clock
controller device node into the same group.

each of these two PWM controllers has one output channel. Due to

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).
So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
But this means that OF-only drivers needs to have both OF and SPI id
tables that have to be kept in sync and also the dev node compatible
manufacturer prefix is stripped when reporting the MODALIAS. Which can
lead to issues if two vendors use the same SPI device name for example.
To avoid the above, the SPI core behavior may be changed in the future
to not require an SPI device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table even when
is unused now to prevent breaking module loading when the core changes.

Building the advansys driver in a big-endian configuration such as
ARM allmodconfig shows a warning:
drivers/scsi/advansys.c: In function 'adv_build_req':
include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer implicitly truncated to unsigned type [-Woverflow]

drivers/scsi/advansys.c:7806:22: note: in expansion of macro 'cpu_to_le32'
scsiqp->sense_len = cpu_to_le32(SCSI_SENSE_BUFFERSIZE);
It turns out that the commit that introduced this used the cpu_to_le32()
incorrectly on an 8-bit field, which results in the sense_len to always
be set to zero, as the SCSI_SENSE_BUFFERSIZE value gets moved to upper
byte of the 32-bit intermediate.
This removes the cpu_to_le32() call to restore the original version.
I found this only by looking at the compiler output and have not done a
full review for possible further endianess bugs in the same driver.

On the commit 3301d40921 ("drm/i915: PSR: Fix DP_PSR_NO_TRAIN_ON_EXIT logic")'
we already had identified that DP_PSR_NO_TRAIN_ON_EXIT
doesn't mean we shouldn't send TPS patterns, however we start sending the
minimal TP1 as possible and no TP2.
For most of the panels this is ok, but we found a reported case where
this is not true and panel keeps frozen without updating the screen for a while.
We could just get this case after patch "PSR: Don't Skip aux handshake on
DP_PSR_NO_TRAIN_ON_EXIT." is applied since that one fix the
hard freeze on this kind of panels.

There we gave more time for idleness by increasing the delay

delay the first activation in a better way keeping a good PSR

When debuging the frozen screen caused by HW tracking with low
power state I noticed that if we keep moving the mouse non stop
you will miss the screen updates for a while. At least
until we stop moving the mouse for a small time and move again.
The actual enabling should happen immediately after
Display Port enabling sequence finished with links trained and
everything enabled. However we face many issues when enabling PSR
right after a modeset.
On VLV/CHV we face blank screens on this scenario and on HSW+
we face a recoverable frozen screen, at least until next
exit-activate sequence.
Another workaround for the same issue here would be to increase
re-enable idle time from 100 to 500 as we did for VLV/CHV.
However this patch workaround this issue in a better
way since it doesn't reduce PSR residency and also
allow us to reduce the delay time between re-enables at least
on VLV/CHV.
This is also important to make the sysfs toggle working properly.

Make I915_READ and I915_WRITE more type safe by wrapping the register
offset in a struct. This should eliminate most of the fumbles we've had
with misplaced parens.
This only takes care of normal mmio registers. We could extend the idea
to other register types and define each with its own struct. That way
you wouldn't be able to accidentally pass the wrong thing to a specific
register access function.
The gpio_reg setup is probably the ugliest thing left. But I figure I'd
just leave it for now, and wait for some divine inspiration to strike
before making it nice.
As for the generated code, it's actually a bit better sometimes. Eg.
looking at i915_irq_handler(), we can see the following change:
lea 0x70024(%rdx,%rax,1),%r9d
mov $0x1,%edx
- movslq %r9d,%r9
- mov %r9,%rsi
- mov %r9,-0x58(%rbp)
- callq *0xd8(%rbx)
+ mov %r9d,%esi
+ mov %r9d,-0x48(%rbp)
callq *0xd8(%rbx)
So previously gcc thought the register offset might be signed and
decided to sign extend it, just in case. The rest appears to be
mostly just minor shuffling of instructions.
v2: i915_mmio_reg_{offset,equal,valid}() helpers added
s/_REG/_MMIO/ in the register defines
mo more switch statements left to worry about
