Move most of usb clock initialization from lpc32xx_udc and ohci-nxp to
clock.c. Also adds ohci clocks and otg clocks.Signed-off-by: Alexandre Pereira da Silva

This patch fixes a bug, (wrongfully) resetting the value of
LPC32XX_CLKPWR_MS_CTRL back to its initial contents (after careful setup). This
was discovered only with a board/bootloader combination (EA3250) where the
contents of the respective register wasn't already at the correct value on
Linux boot.Signed-off-by: Roland Stigge

ARCH_NR_GPIOS was defined statically to include exactly all SoC specific GPIOs.
Now if additional GPIOs need to be added dynamically, e.g. via DT, none are
available. Removing the mach specific setting, leaving ARCH_NR_GPIOS to the
default of 256 (currently in include/asm-generic/gpio.h).Signed-off-by: Roland Stigge

This patch fixes the DTS files for the High Speed UARTs 1, 2 and 7 of the
LPC32xx SoC, adjusting the compatible strings, adding interrupts and status
configuration. On the PHY3250 reference board, UART2 is enabled.Signed-off-by: Roland Stigge
Acked-by: Alexandre Pereira da Silva -
This patch switches from static serial driver initialization to devicetree
configuration. This way, the Standard UARTs of the LPC32xx SoC can be enabled
individually via DT.E.g., instead of Kconfig configuration, the phy3250.dts activates
UARTs 3 and 5.Signed-off-by: Roland Stigge

There is another reference/development board for the LPC32xx SoC (besides the
Phytec 3250): The Embedded Artists LPC3250 board. This patch adds a default dts

This patch takes into account that the MTD NAND MLC controller needs more
registers, located actually before the previously allocated memory range,
already starting at 200a8000 instead of 200b0000.Further, the interrupt for the controller is configured.

This patch adds DMA channel configuration to the LPC32xx platform file. The
configured DMA signalling is generic for LPC32xx SoC and is not board specific.Signed-off-by: Roland Stigge

Since we now support two MTD NAND controllers (MLC and SLC) for LPC32xx via DT,
we don't initialize the SLC controller statically anymore, but do it via the
clock setup (see previous patch).Signed-off-by: Roland Stigge

If the privileges given to root threads (3% of allowable memory) or a
negative value of /proc/pid/oom_score_adj happen to exceed the amount of
rss of a thread, its badness score overflows as a result of commit
a7f638f999ff ("mm, oom: normalize oom scores to oom_score_adj scale only
for userspace").Fix this by making the type signed and return 1, meaning the thread is
still eligible for kill, if the value is negative.Reported-by: Dave Jones

This reverts commit 9e612a008fa7fe493a473454def56aa321479495.
It incorrectly finds VGA connectors where none are attached, apparently
not noticing that nothing replied to the EDID queries, and happily using
the default EDID modes that have nothing to do with actual hardware.That in turn then causes X to fall down to the lowest common
denominator, which is usually the default 1024x768 mode that is in the
default EDID and pretty much anything supports).I'd suggest that if not relying on the HDP pin, the code should at least
check whether it gets valid EDID data back, rather than just assume
there's something on the VGA connector.Cc: Dave Airlie

This reverts commit 7732a557b1342c6e6966efb5f07effcf99f56167 (and commit
3f50fff4dace23d3cfeb195d5cd4ee813cee68b7, which was a follow-up
cleanup).We're chasing an elusive bug that Dave Jones can apparently reproduce
using his system call fuzzer tool, and that looks like some kind of
locking ordering problem on the directory i_mutex chain. Our i_mutex
locking is rather complex, and depends on the topological ordering of
the directories, which is why we have been very wary of splicing
directory entries around.Of course, we really don't want to ever see aliased unconnected
directories anyway, so none of this should ever happen, but this revert
aims to basically get us back to a known older state.Bruce points to some of the previous discussion at
http://marc.info/?i=
and in particular a long post from Neil:
http://marc.info/?i=
It should be noted that it's possible that Dave's problems come from
other changes altohgether, including possibly just the fact that Dave
constantly is teachning his fuzzer new tricks. So what appears to be a
new bug could in fact be an old one that just gets newly triggered, but
reverting these patches as "still under heavy discussion" is the right
thing regardless.Requested-by: Al Viro
