2013-03-09arm: mvebu: Reduce reg-io-width with UARTsHeikki Krogerus2-4/+4
Setting the reg-io-width to 1 byte represents more accurate description of the HW. This will fix an issue where UART driver causes kernel panic during bootup. Gregory CLEMENT traced the issue to autoconfig() in 8250.c, where the existence of FIFO is checked from UART_IIR register. The register is now read as 32-bit value as the reg-io-width is set to 4-bytes. The retuned value seems to contain bogus data for bits 31:8, causing the issue.

2013-03-09ARM: dove: drop "select COMMON_CLK_DOVE"Paul Bolle1-1/+0
Commit 5b03df9ace680d7cdd34a69dfd85ca5f74159d18 ("ARM: dove: switch to DT clock providers") added "select COMMON_CLK_DOVE" to Marvell Dove's Kconfig entry. But there's no Kconfig symbol COMMON_CLK_DOVE, which makes this select statement a nop. It's probably a leftover of some experimental code that never hit mainline. Drop it.

2013-03-09ARM: kirkwood: fix to retain gbe MAC addresses for DT kernelsSebastian Hesselbarth1-7/+18
The ethernet controller used on kirkwood looses its MAC address register contents when the corresponding clock is gated. As soon as mv643xx_eth is built as module, the clock gets gated and when loading the module, the MAC address is gone. Proper DT support for the mv643xx_eth driver is expected soon, so we add a workaround to always enable ge0/ge1 clocks on kirkwood. This workaround is also already used on non-DT kirkwood kernels.

2013-03-09ARM: kirkwood: of_serial: fix clock gating by removing clock-frequencyJason Cooper17-20/+0
When DT support for kirkwood was first introduced, there was no clock infrastructure. As a result, we had to manually pass the clock-frequency to the driver from the device node. Unfortunately, on kirkwood, with minimal config or all module configs, clock-frequency breaks booting because of_serial doesn't consume the gate_clk when clock-frequency is defined. The end result on kirkwood is that runit gets gated, and then the boot fails when the kernel tries to write to the serial port. Fix the issue by removing the clock-frequency parameter from all kirkwood dts files. Booted on dreamplug without earlyprintk and successfully logged in via ttyS0.

Commit 0cc41e4a21d43 (arch: remove direct definitions of KERN_<LEVEL> uses) is broken - not enough thought was put into changing: .asciz "string" to .asciz "string1" "string2" The problem is that each string gets _separately_ NUL terminated, so the result is a string containing: "string1\0string2\0" rather than: "string1string2\0" With our new printk levels, this ends up as - eg, KERN_DEBUG "string": 0x01 0x00 0x07 0x00 "string" 0x00 which produces lots of \x01 in the kernel log.

Notable changes are: - More devices get moved out of board files into device tree descriptions. The remaining devices listed in there have patches that will get sent for 3.10, after which we can remove a lot of the board files entirely. We are doing the pinctrl and mmc drivers here, ethernet and PCI still remain. - SMP support for mvebu is improved with support for the local interrupt controller. - The Guruplug board file gets replaced with a DT description. Unfortunately, the dependency on the MMC tree turned out to be a much larger problem than expected, when the MMC maintainer rebased the patches in his tree that all of the patches in this branch are based on, which caused merge conflicts between the new and old versions of those patches. To work around the merge conflicts, this branch rebases all patches on top of the respective MMC patches that did get merged into 3.9. The patches are all identical to the versions that were part of linux-next, but have a new commit date." * tag 'late-mvebu-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (90 commits) arm: mvebu: enable the SD card slot on Armada 370 Reference Design board ARM: kirkwood: topkick: init mvsdio via DT ARM: kirkwood: nsa310: convert to pinctrl ARM: Kirkwood: topkick: Enable i2c bus.

The Armada XP DB evaluation board has one SD card slot, directly connected to the SDIO IP of the SoC, so we add a device tree description for it. However, in the default configuration of the board, the SD card slot is not usable: the connector plugged into CON40 must be changed against a different one, provided with the board by the manufacturer. Since such a manual modification of the hardware is needed, we did not enable the SDIO interface by default, and left it to the board user to modify the Device Tree if needed. Since this board is really only an evaluation board for developers and not a final product, it is not too bad.

2013-02-28arm: mvebu: enable the SD card slot on Armada XP DB boardThomas Petazzoni1-0/+7
The Armada XP DB evaluation board has one SD card slot, directly connected to the SDIO IP of the SoC, so we enable this IP. Unfortunately, there are no GPIOs for card-detect and write-protect.

2013-02-28arm: mvebu: add pin muxing options for the SDIO interface on Armada XPThomas Petazzoni3-0/+18
The SDIO interface is only available on pins MPP30/31/32/33/34/35 on the various Armada XP variants, so we provide a pin muxing option for this in the Armada XP .dtsi files. Even though those muxing options are the same for MV78230, MV78260 and MV78460, we keep them in each .dtsi file, because the number of pins, and therefore the declaration of the pinctrl node, is different for each SoC variant.

2013-02-28arm: mvebu: add pin muxing options for the SDIO interface on Armada 370Thomas Petazzoni1-0/+12
The SDIO interface is available either on pins MPP9/11/12/13/14/15 or MPP47/48/49/50/51/52 on the Armada 370. Even though all combinations are potentially possible, those two muxing options are the most probable ones, so we provide those at the SoC level .dtsi file. In practice, in turns out the Armada 370 DB board uses the former, while the Armada 370 Mirabox uses the latter.

2013-02-28arm: mvebu: add DT information for the SDIO interface of Armada 370/XPThomas Petazzoni1-0/+8
Now that the mvsdio MMC driver has a Device Tree binding, we add the Device Tree informations to describe the SDIO interface available in the Armada 370/XP SoCs. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-02-28arm: mvebu: Add RTC support for Armada 370 and Armada XPGregory CLEMENT1-0/+6
The Armada 370 and Armada XP Socs have the same controller that the one used in the orion platforms. This patch updates the device tree for these SoCs.

2013-02-28arm: mvebu: update defconfig with ATAG support when using DTGregory CLEMENT1-0/+1
Some of the mvebu boards (mainly the development board) come with plug-in RAM modules. This patch allows to let the bootloaders which have no support for DTS to give the real amount of memory available on the board.
