2009-05-05ARM: ARCH_MXC should select HAVE_CLKGuennadi Liakhovetski1-0/+1
All i.MX platforms support <linux/clk.h> calls and should select HAVE_CLK. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-04-30[ARM] 5489/1: ARM errata: Data written to the L2 cache can be overwritten ↵Catalin Marinas1-0/+12
with stale data This patch is a workaround for the 460075 Cortex-A8 (r2p0) erratum. It configures the L2 cache auxiliary control register so that the Write Allocate mode for the L2 cache is disabled.

2009-04-30[ARM] 5490/1: ARM errata: Processor deadlock when a false hazard is createdCatalin Marinas1-0/+13
This patch adds a workaround for the 458693 Cortex-A8 (r2p0) erratum. It sets the corresponding bits in the auxiliary control register so that the PLD instruction becomes a NOP. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-04-23davinci: major rework of clock, PLL, PSC infrastructureKevin Hilman1-0/+1
This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.

2009-03-23[ARM] pxa: add base support for Marvell's PXA168 processor lineEric Miao1-0/+16
"""The Marvell® PXA168 processor is the first in a family of application processors targeted at mass market opportunities in computing and consumer devices. It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.

2009-03-23[ARM] pxa: introduce plat-pxa for PXA common code and add DMA supportEric Miao1-0/+5
1. introduce folder of 'arch/arm/plat-pxa' for common code across different PXA processor families 2. initially moved DMA code into plat-pxa 3. common code in <mach/dma.h> moved into <plat/dma.h>, new processors should implement its own <mach/dma.h>, provide the following required definitions and '#include <plat/dma.h>' in the end: - DMAC_REGS_VIRT for mapped virtual address of the DMA registers' physical I/O memory Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-15[ARM] add CONFIG_HIGHMEM optionNicolas Pitre1-0/+17
Here it is... HIGHMEM for the ARM architecture. :-) If you don't have enough ram for highmem pages to be allocated and still want to test this, then the cmdline option "vmalloc=" can be used with a value large enough to force the highmem threshold down. Successfully tested on a Marvell DB-78x00-BP Development Board with 2 GB of RAM. Signed-off-by: Nicolas Pitre <nico@marvell.com>

2009-01-06Staging: Kconfig for ARCH=arm,8300, crisF. Duncan M. Haldane1-0/+2
The new Kconfig option to build "staging" drivers (code in drivers/staging/) is seen in all except three architectures (arm, h8300, cris), because in these cases arch/$ARCH/Kconfig does NOT source drivers/Kconfig. This patch adds the source "drivers/staging/Kconfig" to arch/$ARCH/Kconfig for these three exceptional cases.

2008-12-14[ARM] KS8695: Fixup the KS8695 GPIO to be GPIOLIBDaniel Silverstone1-0/+1
This patch is as small a change as possible to the KS8695 GPIO layer to use GPIOLIB to allow the generic GPIO expanders and the like to be compiled. As a side-effect, we also remove __init_or_module from several functions which could be called by drivers such as i2c-gpio which could plausibly be compiled into a non-modular kernel.
