Since BSV irq is only used for B-device, this patch correct the setting of
BSVIE of otgsc only for case of ID change, that is:
- In otg fsm mode, ID change from 0 to 1 means otg state from A_IDLE to
B_IDLE; ID change from 1 to 0 means otg state from B_IDLE to A_IDLE, so
only disable BSVIE if the current state is B_IDLE(to be update to A_IDLE),
only enable BSVIE if the current state is A_IDLE(to be update to B_IDLE).
- In non-otg-fsm mode, it's already correct.This fix the bug of MLK-10243.

By default, NAND driver will choose the highest ecc strength that oob
could contain, in this case, for some 8K+744 NAND flash, the ecc
strength will be up to 52bit, which is beyond the i.MX6QDL BCH
capability (40bit).This code change allows the NAND driver try to use minimum required ecc
strength if it failed to use the highest ecc, even without explicitly
claiming "fsl,use-minimum-ecc" in dts.Signed-off-by: Han Xu

To maintain scalability let's add common methods to attach and detach
a PM domain for a device, dev_pm_domain_attach|detach().Typically dev_pm_domain_attach() shall be invoked from subsystem level
code at the probe phase to try to attach a device to its PM domain.
The reversed actions may be done a the remove phase and then by
invoking dev_pm_domain_detach().When attachment succeeds, the attach function should assign its
corresponding detach function to a new ->detach() callback added in the
struct dev_pm_domain.Signed-off-by: Ulf Hansson

This patch introduces generic code to perform PM domain look-up using
device tree and automatically bind devices to their PM domains.Generic device tree bindings are introduced to specify PM domains of
devices in their device tree nodes.Backwards compatibility with legacy Samsung-specific PM domain bindings
is provided, but for now the new code is not compiled when
CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code.
This will change as soon as the Exynos PM domain code gets converted to
use the generic framework in further patch.This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.Link: http://marc.info/?l=linux-pm&m=139955349702152&w=2
