2017-12-12i2c: imx: implement bus recovery with gpio for LayerscapeZhang Ying-22455
Based on the I2C specification, if the data line (SDA) is stuck low, the master should send nine clock pulses. The I2C slave device that held the bus low should release it sometime within those nine clocks. Because pinctrl is not supported on Layerscape, current bus recovery is not avalible for Layerscape. This patch uses an open drain GPIO pin to connect to the IICx_SCL to drive nine clock pulses to unlock the I2C bus. Signed-off-by: Zhang Ying-22455 <ying.zhang22455@nxp.com>

Commit f44116ae8818 ("PCI: Remove pci_find_parent_resource() use for allocation") updated the logic that iterates over all bus resources and compares them to a given resource, in order to decide whether one is the parent of the latter. This change inadvertently causes pci_find_parent_resource() to disregard resources starting at address 0x0, resulting in an error such as the one below on ARM systems whose I/O window starts at 0x0. pci_bus 0000:00: root bus resource [mem 0x10000000-0x3efeffff window] pci_bus 0000:00: root bus resource [io 0x0000-0xffff window] pci_bus 0000:00: root bus resource [mem 0x8000000000-0xffffffffff window] pci_bus 0000:00: root bus resource [bus 00-0f] pci 0000:00:01.0: PCI bridge to [bus 01] pci 0000:00:02.0: PCI bridge to [bus 02] pci 0000:00:03.0: PCI bridge to [bus 03] pci 0000:00:03.0: can't claim BAR 13 [io 0x0000-0x0fff]: no compatible bridge window pci 0000:03:01.0: can't claim BAR 0 [io 0x0000-0x001f]: no compatible bridge window While this never happens on x86, it is perfectly legal in general for a PCI MMIO or IO window to start at address 0x0, and it was supported in the code before commit f44116ae8818.
