2012-12-24ARM: delete struct sys_timerStephen Warren1-5/+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.

It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel.

2012-08-25clk: convert ARM RealView to common clkLinus Walleij1-0/+2
This converts the ARM RealView machine over to using the common clock. The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

2012-08-23ARM: pmu: remove arm_pmu_type enumerationSudeep KarkadaNagesha1-2/+1
The arm_pmu_type enumeration was initially introduced to identify different PMU types in the system, the usual one being that on the CPU (ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

2012-08-01ARM: mach-realview and mach-versatile: retire custom LED codeBryan Wu1-5/+0
This replaces the custom LED trigger code in mach-realview with some overarching platform code for the plat-versatile family that will lock down LEDs 2 thru 5 for CPU activity indication. The day we have 8 core ARM systems the plat-versatile code will have to become more elaborate. Tested on RealView PB11MPCore by invoking four different CPU hogs (yes > /dev/null&) and see the LEDs go on one at a time. They all go off as the hogs are killed. Tested on the PB1176 as well - just one activity led (led 2) goes on and off with CPU activity.

2012-01-25ARM: 7300/1: realview: fix definition of GPIO0 interrupt on PB1176 to match TRMWill Deacon1-1/+1
Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an AMBA device is registered with this parameter. With the pending NO_IRQ cleanup, this will lead to a warning at boot time, since -1 is obviously broken. This patch updates the interrupt used for GPIO0 to match that specified by the TRM. Unfortunately, it's not clear how to trigger this interrupt so we trust that the documentation is correct.

This adds platform data for the PL022 to the ARM RealView reference designs, adds the necessary clock definition and fixes a badly defined IRQ line on the PB1176. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-07-09ARM: 6204/1: Fixups for the RealView PB1176Linus Walleij1-8/+6
This is a number of basic fixes to the PB1176 that makes it tick properly: - Detect MMC insertion/removal even when PL061 GPIO is not compiled in. The register to read this status directly is removed on the PB1176. - Define the UART3 on the DevChip (where is actually is) and define the new UART4 serial port on the FPGA. - Also define the clocks for these two UARTs apropriately. - Remove the false notion that the PB1176 should have its CLCD on the ISSP, this is not the case, it is in the DevChip. - Remove the defintions and the previously commented-out PL081 DMAC. As confirmed by mail this was found to be broken on the PB1176 board and removed from the subsequent FPGA images.

2010-05-02ARM: 6057/1: Realview: register PMU IRQs during board initialisationWill Deacon1-0/+15
This patch updates the initialisation routines for the Realview boards and the Versatile Express board [ca9x4 tile] so that they register their PMU IRQs with the PMU framework in the Kernel. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-01-11ARM: 5873/1: ARM: Fix the reset logic for ARM RealView boardsColin Tuckley1-6/+4

2009-11-05RealView: Add default memory configurationCatalin Marinas1-0/+13
This patch adds a realview_fixup() function called during booting to set up the memory banks. This way there is no need to pass a "mem=" argument on the kernel command line. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-11-01ARM: 5774/1: Fix Realview ARM1176PB board rebootPhilby John1-0/+11
This is the fix for proper reboot of Realview ARM1176PB board when issuing the reboot command. Setting the eighth bit of control register SYS_RESETCTL to 1 to force a soft reset. arch_reset() is modified for realview machines to call machine specific reset function pointers.

This moves the mmci platform data definition struct away from arch/arm/include/asm/mach/mmc.h into the more proper place among the other primecells in include/linux/amba/mmci.h and at the same time renames it to "mmci.h", and also the struct in this file confusingly named mmc_platform_data has been renamed mmci_platform_data for clarity.

2009-09-21ARM: 5718/1: Sane busids for RealView board componentsLinus Walleij1-19/+19
This removes the totally bogus bus ID:s with two-digit hex numerals either referring to the base address of corresponding versatile machine or just some arbitrarily chosen digit in favor of just using the device identifier as a string. I kept the "dev:" prefix for DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the other processor bus, just in case someone likes them.

2008-12-01RealView: Allow PHYS_OFFSET at 0x70000000Catalin Marinas1-1/+1
RealView boards like PB11MPCore have 512MB of RAM available contiguously at 0x70000000. Half of the memory is mirrored at 0x00000000 for backwards compatibility. This patch adds the CONFIG_REALVIEW_HIGH_PHYS_OFFSET option option to change the physical base address so that the full amount of RAM is available to Linux. Note that the EB board has 256MB of RAM also mirrored at 0x70000000, the only board without this feature being PB1176. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
