* ARM: Kirkwood: Remove mach-kirkwoodAndrew Lunn2014-07-131-746/+0
| | | | | | | | | Now that all boards have been converted to DT and all the support code lives in mach-mvebu, we can remove mach-kirkwood.

* ARM: orion: Move cache-feroceon-l2.h out of plat-orionAndrew Lunn2014-02-221-1/+1
| | | | | | | | | | | With the gradual move to DT, kirkwood has become a lot less dependent on plat-orion. cache-feroceon-l2.h is the last dependency. Move it out so we can drop plat-orion when building DT only kirkwood boards.

* ARM: kirkwood: Add standby supportEzequiel Garcia2013-10-081-0/+1
| | | | | | | | | | | | | Implements standby support for Kirkwood SoC. When the SoC enters standby state the memory PM units are disabled, the DDR is set in self-refresh mode, and the CPU is set in WFI. At this point there's no clock gating, as that is considered each driver's task.

Since there's sometimes a dependency on device-tree changes, there's also a fair amount of those in this branch. Pieces worth mentioning are: - Mbus driver for Marvell platforms, allowing kernel configuration and resource allocation of on-chip peripherals. - Enablement of the mbus infrastructure from Marvell PCI-e drivers. - Preparation of MSI support for Marvell platforms. - Addition of new PCI-e host controller driver for Tegra platforms - Some churn caused by sharing of macro names between i.MX 6Q and 6DL platforms in the device tree sources and header files. - Various suspend/PM updates for Tegra, including LP1 support. - Versatile Express support for MCPM, part of big little support. - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7) - OMAP2+ support for DRA7, a new Cortex-A15-based SoC. The code that touches other architectures are patches moving MSI arch-specific functions over to weak symbols and removal of ARCH_SUPPORTS_MSI, acked by PCI maintainers" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (266 commits) tegra-cpuidle: provide stub when !CONFIG_CPU_IDLE PCI: tegra: replace devm_request_and_ioremap by devm_ioremap_resource ARM: tegra: Drop ARCH_SUPPORTS_MSI and sort list ARM: dts: vf610-twr: enable i2c0 device ARM: dts: i.MX51: Add one more I2C2 pinmux entry ARM: dts: i.MX51: Move pins configuration under "iomuxc" label ARM: dtsi: imx6qdl-sabresd: Add USB OTG vbus pin to pinctrl_hog ARM: dtsi: imx6qdl-sabresd: Add USB host 1 VBUS regulator ARM: dts: imx27-phytec-phycore-som: Enable AUDMUX ARM: dts: i.MX27: Disable AUDMUX in the template ARM: dts: wandboard: Add support for SDIO bcm4329 ARM: i.MX5 clocks: Remove optional clock setup (CKIH1) from i.MX51 template ARM: dts: imx53-qsb: Make USBH1 functional ARM i.MX6Q: dts: Enable I2C1 with EEPROM and PMIC on Phytec phyFLEX-i.MX6 Ouad module ARM i.MX6Q: dts: Enable SPI NOR flash on Phytec phyFLEX-i.MX6 Ouad module ARM: dts: imx6qdl-sabresd: Add touchscreen support ARM: imx: add ocram clock for imx53 ARM: dts: imx: ocram size is different between imx6q and imx6dl ARM: dts: imx27-phytec-phycore-som: Fix regulator settings ARM: dts: i.MX27: Remove clock name from CPU node ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we are going to enable the usage of the mvebu PCIe driver on Kirkwood, we don't want the PCIe windows to be unconditionally created by kirkwood_setup_wins(). Therefore, we move the PCIe window initialization into the legacy PCIe driver (arch/arm/mach-kirkwood/pcie.c). The platforms using the legacy driver will see their windows statically allocated by arch/arm/mach-kirkwood/pcie.c:kirkwood_pcie_init(). The platforms using the new driver in drivers/pci/ will see their windows dynamically allocated directly by the driver.

* arm: mach-kirkwood: convert to use mvebu-mbus driverThomas Petazzoni2013-04-151-2/+36
| | | | | | | | | | | | | | | | | | | This commit migrates the mach-kirkwood platforms to use the mvebu-mbus driver and therefore removes the Kirkwood-specific addr-map code. The kirkwood_init_early() function is now responsible for initializing the mvebu-mbus driver by calling mvebu_mbus_init(). The address decoding windows are now registered in the kirkwood_setup_wins() function. It is worth noting that the four PCIe address decoding windows will ultimately no longer have to be registered here: it will be done automatically by the PCIe driver once Kirkwood has been migrated to use the upcoming mvebu PCIe driver.

* | ARM: delete struct sys_timerStephen Warren2012-12-241-5/+1
|/ | | | | | | | | | | | | | | | | | 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.

There's no need for these any longer as the kernel has been booting fine without them for quite some time.

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>

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>

* ARM: Kirkwood: Fix clk problems modular ethernet driverAndrew Lunn2012-06-161-1/+7
| | | | | | | | | | | | | | | | | | | | | 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.

* ARM: Kirkwood: Replace clock gatingAndrew Lunn2012-05-081-86/+126
| | | | | | | | | | | | | | | | | | | | | | 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.
