Add a minimal device node for the Coresight-ETM hardware block, and hook it up to the D4 PM domain, so the R-Mobile System Controller driver can keep the domain powered, until the new Coresight code handles runtime PM.

2015-02-24ARM: dts: dra7x-evm: beagle-x15: Fix USB HostRoger Quadros3-24/+0
In commit 87517d26d888 ("ARM: dts: dra7-evm: Add extcon nodes for USB") we enabled Extcon USB gpio to tackle the USB ID pin and get peripheral mode to work. But the extcon-gpio-usb driver [1] didn't make it into v4.0 and this makes the USB driver defer probe indefinitely breaking USB Host functionality. As a temporary fix we remove the extcon handle from the USB controller and add it back when the extcon driver merges in v4.1.

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not detect smc91x ethernet hardware in qemu N900 machine. The 0x300 offset was used to supress a warning the smsc911x driver produces about non-standard offset as 0x300 seems to be the EEPROM default. As only three address lines are connected both 0 and 0x300 will work just fine with 0 being correct. The warning about the non-standard offset can be fixed by writing to EEPROM as that's needed in any case to set the MAC address.

2015-02-24ARM: dts: Fix USB dts configuration for dm816xTony Lindgren2-4/+55
Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree configuration") added basic devices for dm816x, but I was not able to test the USB completely because of an unconfigured USB phy, and I only tested it to make sure the Mentor chips are detected and clocked without a phy. After testing the USB with actual devices I noticed a few issues that should be fixed to avoid confusion: - The USB id pin on dm8168-evm is hardwired and can be changed only by software. As there are two USB-A type connectors, let's start both in host mode instead of otg. - The Mentor core is configured in such a way on dm8168-evm that it's not capable of multipoint at least on revision c board that I have. - We need ranges for the syscon to properly set up the phy as children of the SCM syscon area. - Let's not disable the second interface, the board specific dts files can do that if really needed. Most boards should just keep it enabled to ensure the device is idled properly. Note that also a phy and several musb fixes are still needed to make the USB to work properly in addition to this fix.

Add a device node for the System Controller, with subnodes that represent the hardware power area hierarchy. Hook up all devices to their respective PM domains. Note that unlike on R-Mobile A1 (r8a7740), PM domain D4 can be powered down without ill effects on s2ram behavior, just like on SH-Mobile AP4 (sh7372). Hence we can postpone adding a (minimal) device node for the Coresight-ETM hardware block. The System Controller is also used by the R-Mobile Reset driver, which can now restart the system.

2015-02-24ARM: shmobile: kzm9g-reference: Remove board C code and DT fileSimon Horman7-479/+2
Now that the sh73a0 generic multiplatform case has the same feature set as the kzm9g DT reference board code, we get rid of the latter. DT reference code in the future shall make use of the sh73a0 multiplatform support code with the generic SoC machine vector.

2015-02-24ARM: shmobile: kzm9g dts: Move Ethernet node to BSCGeert Uytterhoeven1-13/+15
Move the Ethernet node from the root of the device tree to the BSC node, as it's connected to the Bus State Controller. This allows the system to know the right position of the Ethernet node in the clock and PM domain hierarchy, and manage the clock and PM domain appropriately. Also rename the node's name from "lan9220" to "ethernet", to conform to ePAPR generic name recomendations.

2015-02-24ARM: shmobile: sh73a0 dtsi: Add Bus State Controller nodeGeert Uytterhoeven1-0/+11
Add a node for the Bus State Controller (BSC) on sh73a0, to which multiple external devices can be connected. The BSC is driven by the ZB clock, and located in PM domain A4S. A reference to the latter will be added later. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2015-02-24ARM: shmobile: kzm9g: Build DTS for MultiplatformMagnus Damm1-1/+2

2015-02-24ARM: shmobile: kzm9g dts: Sync with kzm9g-reference dtsMagnus Damm1-1/+373
Sync the two DTS for the KZM9G board. The target is the file "sh73a0-kzm9g.dts" and it is made identical to the DT reference case with the exception of the compatbile string. In the future the DT reference file will go away.

2015-02-24ARM: shmobile: r8a7779: Remove redundant cpu_disable implementationStephen Boyd1-7/+0
By default only the non-boot CPUs can be hotplugged if the smp_operations structure doesn't have the cpu_disable function pointer set. r8a7779_cpu_disable() implements the same logic, only non-boot CPUs can be hotplugged, so it's redundant to override the default behavior.

Move over ARCH_SHMOBILE_LEGACY to use the default legacy ARM implementations of __clk_get() and __clk_put() in <asm/clkdev.h> by deselecting HAVE_MACH_CLKDEV. This has the nice side effect that <mach/clkdev.h> is no longer used and can be removed.
