2014-02-22ARM: MM: Add DT binding for Feroceon L2 cacheAndrew Lunn1-15/+3
Instantiate the L2 cache from DT. Indicate in DT where the cache control register is so that it is possible to enable/disable write through on the CPU.

2014-02-22ARM: orion: Move cache-feroceon-l2.h out of plat-orionAndrew Lunn2-2/+2
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.

2014-02-22ARM: kirkwood: Separate board-dt from common and pcie code.Andrew Lunn2-3/+88
In order to be able to move DT support into mach-mvebu, the DT code needs to be cleanly separated from common and pcie code. Import the needed bits of these files into board-dt.c. The "common" code then becomes purely legacy, supporting non-DT boards, so reflect this in the Makefile targets.

2013-10-08ARM: kirkwood: retain MAC address for DT ethernetSebastian Hesselbarth1-2/+83
Ethernet IP on Kirkwood SoCs loose their MAC address register content if clock gated. To allow modular ethernet driver setups and gated clocks also on non-DT capable bootloaders, we fixup port device nodes with no valid MAC address property. This patch copies MAC address register contents set up by bootloaders early, notably before ethernet clocks are gated. While at it, also reorder call sequence in _dt_init.

kirkwood_setup_wins is the last manual caller of mbus in kirkwood, don't call it for DT boards and rely on the DT having a mbus node with a proper ranges property to setup these windows. Move all the mbus ranges properties for all boards into kirkwood.dtsi, since they are currently all the same. This makes the DT self consistent, since the physical address of the NAND and CRYPTO are both referenced internally. The arbitary Linux constants KIRKWOOD_NAND_MEM_PHYS_BASE and KIRKWOOD_SRAM_PHYS_BASE no longer have to match the DT values.

2013-08-06ARM: kirkwood: Split DT and legacy MBus initializationEzequiel Garcia2-4/+5
This commit replaces the legacy MBus initialization with the new DT-based in Kirkwood. For boards that are not yet converted to DT, we keep the legacy initialization.

2013-08-06ARM: kirkwood: Move to ID based MBus window creationThomas Petazzoni2-20/+38
With the introduction of the ID based MBus API, it's better to switch to use it instead of the current name based scheme. This will allow to deprecate the name based API, once every user is removed.

2013-07-25ARM: kirkwood: convert to DT irqchip and clocksourceSebastian Hesselbarth3-9/+40
With recent support for true irqchip and clocksource drivers for Orion SoCs, now make use of it on DT enabled Kirkwood boards. This also introduces a new Kconfig option for legacy (non-DT) Kirkwood where old code is moved out to and polishes DT board file a little bit.

With DT support for mv643xx_eth board specific init for some boards now is unneccessary. Remove those board files, Kconfig entries, and corresponding entries in kirkwood_defconfig.

2013-07-11Watchdog: allow orion_wdt to be built for DoveRussell King1-2/+0
The watchdog infrastructure in Dove is no different from that in Orion5x or Kirkwood, so let's enable it for Dove. The only things missing are a few register settings in Dove's bridge-regs.h. Rather than duplicating the same register bit masks for the RSTOUTn_MASK and BRIDGE_CAUSE registers, move the definitions into the watchdog driver itself.

Since the shmobile platform still uses board files for some of the newer machines, we get a few changes there as the result of drivers getting enabled for those boards. This causes some conflicts with contents getting added from multiple branches in sh-mobile specific files. Renesas is putting a lot of work into migrating to device-tree based setup, which will make all those files obsolete in the future and avoid both the conflicts and the need to have these files in the first place." * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (49 commits) arm: multi_v7_defconfig: Enable initrd/initramfs support arm: multi_v7_defconfig: Enable Zynq UART driver ARM: omap2plus_defconfig: enable USB_PHY and NOP_USB_XCEIV ARM: OMAP1: nokia770: enable Tahvo ARM: OMAP3EVM: Marking omap3_evm_display_init() with CONFIG_BROKEN arm: omap: board-overo: reset GPIO for SMSC911x ARM: shmobile: BOCK-W: change Ether device name ARM: ux500: board-mop500: remove unused pin modes ARM: shmobile: bockw: add MMCIF support ARM: shmobile: bockw: add SPI FLASH support ARM: shmobile: bockw: add I2C device support ARM: shmobile: BOCK-W: add Ether support ARM: tegra: defconfig updates ARM: shmobile: bockw defconfig: add MMCIF support ARM: shmobile: bockw defconfig: add M25P80 support ARM: shmobile: bockw defconfig: add RTC RX8581 support ARM: shmobile: marzen: keep local function as static ARM: shmobile: bockw: add SDHI0 support ARM: shmobile: marzen: Use INTC External IRQ pin driver for SMSC ARM: shmobile: lager: support GPIO switches ...

MPP_F6281_MASK would be previously be returned when on mv88f6282, which would disallow some valid MPP configurations.
