2014-06-07mips: dts: Fix missing device_type="memory" property in memory nodesLeif Lindholm1-0/+1
commit dfc44f8030653b345fc6fb337558c3a07536823f upstream. A few platforms lack a 'device_type = "memory"' for their memory nodes, relying on an old ppc quirk in order to discover its memory. Add the missing data so that all parsing code can find memory nodes correctly.

2013-05-18Merge branch 'devm_no_resource_check' of ↵Linus Torvalds1-4/+0
git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull devm usage cleanup from Wolfram Sang: "Lately, I have been experimenting how to improve the devm interface to make writing device drivers easier and less error prone while also getting rid of its subtle issues. I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

2012-11-30kbuild: centralize .dts->.dtb ruleStephen Warren1-3/+0
All architectures that use cmd_dtc do so in almost the same way. Create a central build rule to avoid duplication. The one difference is that most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather than building the .dtb in the same directory as the .dts file. This difference will be eliminated arch-by-arch in future patches. MIPS is the exception here; it already uses the exact same rule as the new common rule, so the duplicate is removed in this patch to avoid any conflict. arch/mips changes courtesy of Ralf Baechle. Update Documentation/kbuild to remove the explicit call to cmd_dtc from the example, now that the rule exists in a centralized location.

Pull MIPS updates from Ralf Baechle: "The whole series has been sitting in -next for quite a while with no complaints. The last change to the series was before the weekend the removal of an SPI patch which Grant - even though previously acked by himself - appeared to raise objections. So I removed it until the situation is clarified. Other than that all the patches have the acks from their respective maintainers, all MIPS and x86 defconfigs are building fine and I'm not aware of any problems introduced by this series. Among the key features for this patch series is a sizable patchset for Lantiq which among other things introduces support for Lantiq's flagship product, the FALCON SOC. It also means that the opensource developers behind this patchset have overtaken Lantiq's competing inhouse development team that was working behind closed doors. Less noteworthy the ath79 patchset which adds support for a few more chip variants, cleanups and fixes. Finally the usual dose of tweaking of generic code."

Move the 2 drivers from arch/mips/lantiq/xway/ to the subsystem and make them buildable. The following 2 patches will convert the drivers to OF.

2012-05-21MIPS: pci: convert lantiq driver to OFJohn Crispin1-1/+4
Implement support for OF inside the lantiq PCI driver. The patch also splits pcibios_plat_dev_init and pcibios_map_irq out into their own file to accomodate coexistance with the upcoming pcie driver.

Add code to make the dma driver load as a platform device from the devicetree. Signed-off-by: John Crispin <blogic@openwrt.org> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3824/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-05-21MIPS: lantiq: implement support for clkdev apiJohn Crispin9-463/+662
This patch unifies all clock generation and gating code into one file. All drivers will now be able to request their clocks via their device. This patch also adds support for the clockout feature, which allows clock generation on external pins. Support for COMMON_CLK will be provided in the next series.

2012-05-21MIPS: lantiq: drop ltq_gpio_request() and gpio_to_irq()John Crispin2-17/+0
As part of the conversion to OF we also implement pinctrl drivers. Previously we used ltq_gpio_request() to set pinmuxing. This is now obselete and we can hence drop the function. Additionally we remove gpio_to_irq() from the gpio driver and move it to a header file.

2012-05-21OF: MIPS: lantiq: implement irq_domain supportJohn Crispin1-76/+102
Add support for irq_domain on lantiq socs. The conversion is straight forward as the ICU found inside the socs allows the usage of irq_domain_add_linear. Harware IRQ 0->7 are the generic MIPS IRQs. 8->199 are the Lantiq IRQ Modules. Our irq_chip callbacks need to substract 8 (MIPS_CPU_IRQ_CASCADE) from d->hwirq to find out the correct offset into the Interrupt Modules register range.
