2012-09-21arm: add documentation describing Marvell families of SoCThomas Petazzoni
As stated in the introduction of the document, the families of ARM SoCs at Marvell are very complicated, and it is difficult for newcomers to understand the organization of this SoC family and how it relates to the Linux kernel support for those hardware platforms. This document is only at RFC stage for now, it requires reviews and comments from the Marvell maintainers, the PXA maintainers and the MMP maintainers. For correctness of course, but also to add any other information that would be useful. For example, one of the thing that wasn't clear how to detail in the documentation is how the SoCs relate to each other in terms of hardware IP blocks. For example, most of the Kirkwood/Dove/Armada 370-XP/etc. hardware IPs (I2C, SPI, USB, SATA, etc.) are identical, while the PXA and MMP families are completely separate.

2012-09-19ARM: bcm2835: add system timerSimon Arlott
The System Timer peripheral provides four 32-bit timer channels and a single 64-bit free running counter. Each channel has an output compare register, which is compared against the 32 least significant bits of the free running counter values, and generates an interrupt. Timer 3 is used as the Linux timer. The BCM2835 also contains an SP804-based timer module. However, it apparently has significant differences from the standard SP804 IP block, and Broadcom's documentation recommends using the system timer instead. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved to drivers/clocksource/. This looks like the desired location for such code now. * Added DT binding docs. * Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more. * Simplified bcm2835_time_init() to find one matching node and operate on it, rather than looping over all matching nodes. This seems more consistent with other clocksource code. * Simplified bcm2835_time_init() using of_iomap(). * Renamed struct bcm2835_timer.index to match_mask to better represent its purpose. * s/printk(PR_INFO/pr_info(/ Signed-off-by: Chris Boot <bootc@bootc.net> Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: Dom Cobley <popcornmix@gmail.com> Signed-off-by: Dom Cobley <dc4@broadcom.com> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Arnd Bergmann <arnd@arndb.de>
2012-09-19ARM: bcm2835: add interrupt controller driverSimon Arlott
The BCM2835 contains a custom interrupt controller, which supports 72 interrupt sources using a 2-level register scheme. The interrupt controller, or the HW block containing it, is referred to occasionally as "armctrl" in the SoC documentation, hence the symbol naming in the code. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved implementation to drivers/irchip/. * Added devicetree documentation, and hence removed list of IRQs from bcm2835.dtsi. * Changed shift in MAKE_HWIRQ() and HWIRQ_BANK() from 8 to 5 to reduce the size of the hwirq space, and pass the total size of the hwirq space to irq_domain_add_linear(), rather than just the number of valid hwirqs; the two are different due to the hwirq space being sparse. * Added the interrupt controller DT node to the top-level of the DT, rather than nesting it inside a /axi node. Hence, changed the reg value since /axi had a ranges property. This seems simpler to me, but I'm not sure if everyone will like this change or not. * Don't set struct irq_domain_ops.map = irq_domain_simple_map, hence removing the need to patch include/linux/irqdomain.h or kernel/irq/irqdomain.c. * Simplified armctrl_of_init() using of_iomap(). * Removed unused IS_VALID_BANK()/IS_VALID_IRQ() macros. * Renamed armctrl_handle_irq() to prevent possible symbol clashes. * Made armctrl_of_init() static. * Removed comment "Each bank is registered as a separate interrupt controller" since this is no longer true. * Removed FSF address from license header. * Added my name to copyright header.

2012-09-19ARM: add infra-structure for BCM2835 and Raspberry PiSimon Arlott
The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic support for this SoC. http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf Note that the documentation in the latter .pdf assumes the MMU setup that's used on the "VideoCore" companion processor, and does not document physical peripheral addresses. Subtract 0x5e000000 to obtain the physical addresses. This is accounted for by the ranges property in the /soc node in the device tree. The BCM2835 SoC is used in the Raspberry Pi. This patch also adds a minimal device tree for this board; enough to see some very early kernel boot messages through earlyprintk. However, this patch does not yet provide a useful booting system. http://www.raspberrypi.org/. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split from 3-4 months ago, and significantly stripped down and modified since.

It really becomes an maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx6q client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.

2012-09-11clk: mxs: replace imx28 clk_register_clkdev with clock DT lookupShawn Guo
It really becomes a maintenance issue that every time a device needs to look up (clk_get) a clock we have to patch kernel clock file to call clk_register_clkdev for that clock. Since clock DT support which is meant to resolve clock lookup in device tree is in place, the patch moves imx28 client devices' clock lookup over to device tree, so that any new lookup to be added at later time can just get done in DT instead of kernel.

2012-09-07gpio: samsung: add devicetree init for s3c24xx archesHeiko Stuebner
Until now the EXYNOS-SoC was the only Samsung-SoC supporting the GPIOs via the device tree. This patch implements dt-support for the s3c24xx arches. The controllers contain only 3 cells, as the underlying gpio controller does not support controlling the drive strength on a gpio level. Tested with the gpio-keys driver on a s3c2416 based machine.

2012-09-04Merge commit 'a849088aa1' from rmk/fixes into cleanup/io-pciArnd Bergmann
As Stephen Rothwell reports, a849088aa155 ("ARM: Fix ioremap() of address zero") from the arm-current tree and commit c2794437091a ("ARM: Add fixed PCI i/o mapping") from the arm-soc tree conflict in a nontrivial way in arch/arm/mm/mmu.c. Rob Herring explains: The PCI i/o reserved area has a dummy physical address of 0 and needs to be skipped by ioremap searches. So we don't set VM_ARM_STATIC_MAPPING to prevent matches by ioremap. The vm_struct settings don't really matter when we do the real mapping of the i/o space. Since commit a849088aa155 is at the start of the fixes branch in the arm tree, we can merge it into the branch that contains the other ioremap changes.
