If the Orion WDT driver is built as a module, an opps occurs during
|
||||||
|
clk lookup when calling mvebu_clk_gating_get_src(). Remove the
|
||||||
|
inappropriate __init tag so the function is available for modules
|
||||||
|
after kernel init.

When mv_xor_channel_add() fails for one XOR channel, we jump to the
|
||||||
|
err_channel_add label to clean up all previous channels that had been
|
||||||
|
initialized correctly. Unfortunately, while handling this error
|
||||||
|
condition, we were disposing the IRQ mapping before calling
|
||||||
|
mv_xor_channel_remove() (which does the free_irq()), which is
|
||||||
|
incorrect.
|
||||||
|
|
||||||
|
Instead, do things properly in the reverse order of the
|
||||||
|
initialization: first remove the XOR channel (so that free_irq() is
|
||||||
|
done), and then dispose the IRQ mapping.
|
||||||
|
|
||||||
|
This avoids ugly warnings when for some reason one of the XOR channel
|
||||||
|
fails to initialize.

When a channel fails to initialize, we release all ressources,
|
||||||
|
including clocks. However, a XOR unit is not necessarily associated to
|
||||||
|
a clock (some variants of Marvell SoCs have a clock for XOR units,
|
||||||
|
some don't), so we shouldn't unconditionally be releasing the clock.
|
||||||
|
|
||||||
|
Instead, just like we do in the mv_xor_remove() function, we should
|
||||||
|
check if one clock was found before releasing it.

In order for the driver to behave properly in a SMP context, the same
|
||||||
|
transmit queue should be used by the kernel in dev_queue_xmit() and in
|
||||||
|
the driver's mvneta_tx() function. To achieve that, the driver now
|
||||||
|
implements the ->ndo_select_txq() operation.
|
||||||
|
|
||||||
|
For now, it always returns the same transmit queue, txq_def, until the
|
||||||
|
driver is expanded to properly take advantage of the multiqueue
|
||||||
|
capabilities of the hardware.
|
||||||
|
|
||||||
|
Without this patch, the network driver crashes the kernel almost
|
||||||
|
immediately on Armada XP platforms, if the network load is at least a
|
||||||
|
little bit parallel (i.e several threads).

The Armada XP GPIO controller has two ways of notifying interrupts:
|
||||||
|
using global interrupts or using per-CPU interrupts. In an attempt to
|
||||||
|
use the best available features, the 'marvell,armadaxp-gpio'
|
||||||
|
compatible string selects a variant of the gpio-mvebu driver that
|
||||||
|
makes use of the per-CPU interrupts.
|
||||||
|
|
||||||
|
Unfortunately, this doesn't work properly in a SMP context, because we
|
||||||
|
fall into cases where the GPIO interrupt is enabled on CPU X at the
|
||||||
|
GPIO controller level, but on CPU Y at the interrupt controller
|
||||||
|
level. It is not yet clear how to fix that easily.
|
||||||
|
|
||||||
|
So for 3.8, our approach is to switch to global interrupts for GPIOs,
|
||||||
|
so that we do not fall into this per-CPU interrupts problem.
|
||||||
|
|
||||||
|
This patch therefore fixes GPIO interrupts on Armada XP
|
||||||
|
platforms. Without this patch, GPIO interrupts simply do not work
|
||||||
|
reliably, because their proper operation depends on which CPU the code
|
||||||
|
requesting the interrupt is running.

set of helper functions to simplify the management of the write

simpler, and therefore ease the process of adding a Device Tree

The MMC core subsystem provides in drivers/mmc/core/slot-gpio.c a nice
|
||||||
|
set of helper functions to simplify the management of the card detect
|
||||||
|
GPIO in MMC host drivers. This patch migrates the mvsdio driver to
|
||||||
|
using those helpers, which will make the ->probe() code simpler, and
|
||||||
|
therefore ease the process of adding a Device Tree binding for this
|
||||||
|
driver.

This patch adds a simple Device Tree binding for the mvsdio driver, as
|
||||||
|
well as the necessary documentation for it. Compatibility with non-DT
|
||||||
|
platforms is preserved, by keeping the platform_data based
|
||||||
|
initialization.
|
||||||
|
|
||||||
|
We introduce a small difference between non-DT and DT platforms: DT
|
||||||
|
platforms are required to provide a clocks = <...> property, which the
|
||||||
|
driver uses to get the frequency of the clock that goes to the SDIO
|
||||||
|
IP. The behaviour on non-DT platforms is kept unchanged: a clock
|
||||||
|
reference is not mandatory, but the clock frequency must be passed in
|
||||||
|
the "clock" field of the mvsdio_platform_data structure.

On many Marvell SoCs, the pins used for the SDIO interface are part of
|
||||||
|
the MPP pins, that are muxable pins. In order to get the muxing of
|
||||||
|
those pins correct, this commit integrates the mvsdio driver with the
|
||||||
|
pinctrl infrastructure by calling devm_pinctrl_get_select_default()
|
||||||
|
during ->probe().
|
||||||
|
|
||||||
|
Note that we permit this function to fail because not all Marvell
|
||||||
|
platforms have yet been fully converted to using the pinctrl
|
||||||
|
infrastructure.

Even though those muxing options are the same for MV78230, MV78260 and

Subject: [PATCH] arm: cache-l2x0: aurora: Invalidate during clean operation
|
||||||
|
with WT enable
|
||||||
|
|
||||||
|
This patch fixes a bug for Aurora L2 cache controller when the
|
||||||
|
write-through mode is enable. For the clean operation even if we don't
|
||||||
|
have to flush the lines we still need to invalidate them.

Subject: [PATCH] arm: cache-l2x0: aurora: Use writel_relaxed instead of
|
||||||
|
writel
|
||||||
|
|
||||||
|
The use of writel instead of writel_relaxed lead to deadlock in some
|
||||||
|
situation (SMP on Armada 370 for instance). The use of writel_relaxed
|
||||||
|
as it was done in the rest of this driver fixes this bug.

Subject: [PATCH] arm: mvebu: Use dw-apb-uart instead of ns16650 as UART
|
||||||
|
driver
|
||||||
|
|
||||||
|
The UART controller used in the Armada 370 and Armada XP SoCs is the
|
||||||
|
Synopsys DesignWare 8250 (aka Synopsys DesignWare ABP UART). The
|
||||||
|
improper use of the ns16550 can lead to a kernel oops during boot if
|
||||||
|
a character is sent to the UART before the initialization of the
|
||||||
|
driver. The DW APB has an extra interrupt that gets raised when
|
||||||
|
writing to the LCR when busy. This explains why we need to use
|
||||||
|
dw-apb-uart driver to handle this.
