2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-08-13Merge branch 'cleanup/io-pci' into next/cleanupsArnd Bergmann
From Rob Herring <robherring2@gmail.com>: This is the 2nd part of mach/io.h removals. This series removes io.h on platforms with PCI by creating a fixed virtual I/O mapping and a common __io() macro. This version has changed a bit to accommodate Tegra converting its PCIe host to a platform driver. Now the virtual space is only reserved during early boot before .map_io() is called. The mapping is not created until calling pci_ioremap_io which can be done at any point after vmalloc is initialized. I've gone back to fixed 64K windows for each PCI bus. This allows removing all the i/o resource setup from the individually platforms and placing it within the common ARM PCI code. I've only tested versatilepb under qemu (with the model hacked up to actually enable i/o space), so any testing is appreciated. iop3xx and mv78xx0 have some risk of breaking as the PCI bus addresses are moved to 0 from matching the cpu host bus addesss. * cleanup/io-pci: ARM: iop3xx: use fixed PCI i/o mapping ARM: mv78xx0: use fixed pci i/o mapping ARM: iop13xx: use fixed PCI i/o mapping iop13xx: use more regular PCI I/O space handling ARM: orion5x: use fixed PCI i/o mapping ARM: kirkwood: use fixed PCI i/o mapping ARM: dove: use fixed PCI i/o mapping ARM: footbridge: use fixed PCI i/o mapping ARM: shark: use fixed PCI i/o mapping ARM: integrator: remove trailing whitespace on pci_v3.c ARM: integrator: use fixed PCI i/o mapping ARM: tegra: use fixed PCI i/o mapping ARM: versatile: use fixed PCI i/o mapping ARM: move PCI i/o resource setup into common code ARM: Add fixed PCI i/o mapping i2c: iop3xx: use standard gpiolib functions i2c: iop3xx: clean-up trailing whitespace Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2012-07-25ARM: Kirkwood: Fix PHY disable clk problemsSimon Baatz
Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce (ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom variant of clock gating which allows to define a function to be called before gating the clock off. This is used to disable the SATA and PCIe PHYs if the respective clocks are unused after initialization. However, of these two drivers, the SATA driver may be compiled as a module. The driver re-enables the clocks at module init but the PHYs stay disabled. Since the custom clock gating disabled the PHYs when gating the clock off, it should also re-enable them when enabling the clock gate. This is done by adding a second function that may be used to enable the PHYs. Signed-off-by: Simon Baatz <gmbnomis@gmail.com> Signed-off-by: Andrew Lunn <andrew@lunn.ch>

2012-06-16ARM: Kirkwood: Fix clk problems modular ethernet driverAndrew Lunn
When the ethernet driver was built as a module, it would lock the machine when loaded. At boot the ethernet clks are unused, so get turned off. Later, when the module is loaded, the probe function would access the hardware before the clock was restarted, and the machine would lock. It has also been determined that when the clk is turned off, the interface forgets its MAC address, which for most systems, is set by the boot loader. When the machine setup file creates a platform device for the interface, prepare and enable the clock for the interface. This will ensure it is not turned off. However, if the setup file only instantiates one platform device, the other will have its clk disabled, thus maybe saving a little power.

Add a varient of the basic clk-gate code. This variant calls a function before gating the clock off. This function is used to disable the SATA or PCIe PHY. Now that all the drivers prepare and enable there clk as needed, there is no need for the common code to keep track of which clocks need gating on. Let the common clock framework turn off clocks which are not used. Buy using the added clk varient, when the clk framework turns off SATA or PCIe clocks, we also disabled SATA and PCIe PHYs which were not needed. The function kirkwood_pcie_id() can now be called outside of __init code, so remove this property for it, and functions it calls.

2012-02-09ARM: orion: Fix USB phy for orion5x.Andrew Lunn
The patch "ARM: orion: Consolidate USB platform setup code.", commit 4fcd3f374a928081d391cd9a570afe3b2c692fdc broke USB on TS-7800 and other orion5x boards, because the wrong type of PHY was being passed to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION and all the others want EHCI_PHY_NA. Allow the mach- code to tell the generic plat-orion code which USB PHY enum to place into the platform data. Version 2: Rebase to v3.3-rc2.
