| * ARM: integrator: basic PCIv3 device tree supportLinus Walleij2013-06-155-36/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This registers the memory ranges for I/O, non-prefetched and prefetched memory and configuration space for the PCIv3 bridge and let us fetch these basic memory resources from the device tree in the device tree boot path. Remove the stepping stone platform device. This is an either/or approach - the platform data path is mutually exclusive to the plain platform data path and provided addresses from the device tree have to be correct. This adds the interrupt-map property to the PCIv3 DTS file and makes the bridge obtain mappings from the device tree.

| * ARM: integrator: move V3 register definitions into driverLinus Walleij2013-06-032-187/+159
| | | | | | | | | | | | | | | | | | | | This moves the PCIv3 register definitions into the driver itself. There is no other driver or board code including this file, nor will there be. If some other platform needs this driver it should be generalized to support several platforms. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | | | This converts the PCIv3 driver to a platform device driver, and registers the device only on the Integrator/AP instead of bailing out in the initcall if the platform is not correct.

| * ARM: integrator: merge PCIv3 driver into one fileLinus Walleij2013-06-034-123/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Integrator/AP PCI bridget, "v3" is contained in two files, where pci.c is a socket container to plug in the v3 device. However to transition the v3 to enable device tree probing, it need to be converted to a platform device (so that it can have a device node in the device tree) and then we want the PCI driver in a single file, as any other device driver, so we can handle variants using compatible strings and device name, and get the base address etc from resources connected to the device node. To move toward this goal we consolidate all code in the pci_v3.c file. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
| * ARM: pci: create pci_common_init_dev()Linus Walleij2013-06-032-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When working with device tree support for PCI on ARM you run into a problem when mapping IRQs from the device tree irqmaps: doing this the code in drivers/of/of_pci_irq.c will try to find the OF node on the root bridge and this fails, because bus->dev.of_node is NULL, and that in turn boils down to the fact that pci_set_bus_of_node() has called pcibios_get_phb_of_node() from drivers/pci/of.c to obtain the OF node of the bridge or its parent and none is set and thus NULL is returned. Fix this by adding an additional parent argument API for registering PCI bridges on the ARM architecture called pci_common_init_dev(), and pass along this parent to pci_scan_root_bus() called from pcibios_init_hw() in bios32.c and voila: the IRQ mappings start working: the OF node can be retrieved from the parent. Create the old pci_common_init() as a wrapper around the new call.

But it depends on some configurations from DT and a common hook function for different Tegra SoCs to power gate the CPU rail. And these stuffs are initialized after common Tegra suspend init function. So we move the CPUidle init behind the suspend init function. And making the CPUidle driver more generic.

Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it...

For the Marzen board, this new function will be called from marzen_init() to register the USB PHY device early enough. Note that the board and the SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board.
