Hello,
This patch series allows to use the leds-ns2 driver with the n090401
boards (Seagate NAS 4-Bay), based on an Armada-370 SoC.
Here is the list changes:
- Allow to configure the LED mode mapping.
- Handle can_sleep GPIOs. On n090401, the LEDs are connected to an I2C
GPIO expander.
- Make leds-ns2 depends on MACH_ARMADA_370.
Changes for v2:
- Fix gpio_{get,set}_*_cansleep() usage while holding a spinlock:
Holding a spinlock at this places was not needed.
- Add Acked-by from Jacek Anaszewski for patch 4.
Simon

From: Vincent Donnefort <vdonnefort@gmail.com>
On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO
values to LED mode) is different from the one used on other boards
supported by the leds-ns2 driver.
With this patch the hardcoded mapping is removed from leds-ns2. Now,
it must be defined either in the platform data (if an old-fashion board
setup file is used) or in the DT node. In order to allow the later, this
patch also introduces a modes-map property for the leds-ns2 DT binding.

Since the LED modes mapping is no longer hardcoded inside the leds-ns2
driver, then it must be provided through the modes-map property in the
ns2-leds nodes.

On the board n090401 (Seagate NAS 4-Bay), some of the LEDs are handled
by the leds-ns2 driver. This LEDs are connected to an I2C GPIO expander
(PCA95554PW) which means that GPIO access may sleep. This patch makes
leds-ns2 compatible with such GPIOs by using the *_cansleep() variant of
the GPIO functions. As a drawback this functions can't be used safely in
a timer context (with the timer LED trigger for example). To fix this
issue, a workqueue mechanism (copied from the leds-gpio driver) is used.
Note that this patch also updates slightly the ns2_led_sata_store
function. The LED state is now retrieved from cached values instead of
reading the GPIOs previously. This prevents ns2_led_sata_store from
working with a stale LED state (which may happen when a delayed work
is pending).

The leds-ns2 driver is also used by the n090401 board (Seagate NAS
4-Bay), which is based on the Marvell Armada-370 SoC.
Then this patch allows to select the leds-ns2 driver if MACH_ARMADA_370
is enabled. Additionally, this also updates the Kconfig help message.

As the other patch of the series seem to be merged in the led branch,
then I can apply this patch on mvebu/dt.
It is OK for being in linux-next, however this patch depend on "leds:
leds-ns2: move LED modes mapping outside of the driver", so I will need
to find a way to express this dependency when I will do the pull request
to arm-soc.
Thanks,
Gregory
