This is a backport of the patches accepted to the Linux mainline related to mvebu SoC (Armada XP and Armada 370) between Linux v3.12, and Linux v3.13. This work mainly covers: * Finishes work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c) between the PXA family, and the Armada family. * timer initialization update, and access function for the Armada family. * Generic IRQ handling backporting. * Some bug fixes.

Subject: [PATCH 201/203] PCI: mvebu: increment nports only for registered
|
|
ports
|
|
|
|
The number of ports is probed by counting the number of available child nodes.
|
|
Later on, the registration of a port can fail and cause a mismatch between
|
|
the ->nports counter and registered ports. This patch modifies the counting
|
|
strategy, to make ->nports represent the number of registered ports instead
|
|
of the number of available childs.
