mm: replace get_vaddr_frames() write/force parameters with gup_flags

2016-10-19T15:11:24+00:00

This removes the 'write' and 'force' from get_vaddr_frames() and
replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in
callers as use of this flag can result in surprising behaviour (and
hence bugs) within the mm subsystem.

[media] rcar-vin: add R-Car gen2 fallback compatibility string

2016-09-22T15:52:55+00:00

Such fallback string is present in the 'soc_camera' version of the R-Car VIN
driver, so need  to add it here as well...

[media] exynos4-is: add of_platform_populate() call for FIMC-IS child devices

2016-09-22T13:20:06+00:00

Instead of relying on the "simple-bus" compatible and the driver core
populating FIMC-IS child devices make the fimc-is driver populating
its child devices.  This prevents issues related to accessing ISP_I2C
clock registers with corresponding power domain switched off, which
popped out after applying some pending IOMMU driver patches.  Now the
I2C_ISP child devices will be instantiated only when required parent
device drivers are initialized and ready.

[media] exynos4-is: Clear isp-i2c adapter power.ignore_children flag

2016-09-22T13:16:17+00:00

Since commit 04f59143b571161d25315dd52d7a2ecc022cb71a
("i2c: let I2C masters ignore their children for PM")
the power.ignore_children flag is set when registering an I2C
adapter.  Since I2C transfers are not managed by the fimc-isp-i2c
driver its clients use pm_runtime_* calls directly to communicate
required power state of the bus controller.

However, when the power.ignore_children flag is set that doesn't
work, so clear that flag back after registering the adapter.
While at it drop pm_runtime_enable() call on the i2c_adapter
as it is already done by the I2C subsystem when registering
I2C adapter.

This patch is meant as a minimal change to fix the regression,
eventually the I2C_ISPx clock handling will be moved to the
top level fimc-is driver and whole runtime PM code is going to
be dropped from the fimc-is-i2c module.

[media] exynos4-is: Improve clock management

2016-09-22T13:14:27+00:00

There is no need to keep all clocks prepared all the time. Call to
clk_prepare/unprepare can be done on demand from runtime pm callbacks
(it is allowed to call sleeping functions from that context).

2016-09-22T13:13:53+00:00

This patch adds 3 more clocks to Exynos4 ISP driver. Enabling them is
needed to make the hardware operational. Till now it worked only because
those clocks were registered with IGNORE_UNUSED flag and were enabled
by default after SoC reset.

[media] s5p-jpeg: fix system and runtime PM integration

Use generic helpers instead of open-coding usage of runtime PM for system
sleep PM, which was potentially broken for some corner cases.
