2008-12-16pcm038: add driver for static ramSascha Hauer
The pcm038 module (phyCORE-i.MX27) comes with a 512 KiB static RAM which can be battery buffered. Add mtd_ram support and configure the chip select line, to which the sram is attached. Signed-off-by: Luotao Fu <l.fu@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-12-16i.MX31: fix mxc_iomux_set_pad()Guennadi Liakhovetski
mxc_iomux_set_pad() is buggy on i.MX31 - it calculates the register and the offset therein wrongly. Fix it. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2008-12-16[ARM] MX1/MX2: simplify mxc_gpio_setup_multiple_pinsSascha Hauer
mxc_gpio_setup_multiple_pins used to take several ALLOC_MODE flags. Most of them are unused, so simplify the function by removing the flags. Also, instead of using a confusing MXC_GPIO_ALLOC_MODE_RELEASE flag in a function having alloc in its name, add a mxc_gpio_release_multiple_pins function.

2008-12-14[ARM] eliminate NULL test and memset after alloc_bootmemJulia Lawall
As noted by Akinobu Mita in patch b1fceac2b9e04d278316b2faddf276015fc06e3b, alloc_bootmem and related functions never return NULL and always return a zeroed region of memory. Thus a NULL test or memset after calls to these functions is unnecessary. This was fixed using the following semantic patch.

2008-12-14[ARM] KS8695: Fixup the KS8695 GPIO to be GPIOLIBDaniel Silverstone
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.

2008-12-14[ARM] KS8695: Fix up device registration.Daniel Silverstone
The KS8695 device.c provides registration functionality for the KS8695's various devices such as watchdog timers and ethernet devices. Rather than predicating those on the config options for the drivers, always register the platform devices so that a later built module can hook on. Also, the ethernet used to register virtual addresses in the platform data. This is wrong and so this patch changes them to physical addresses and also passes in the appropriate physical region for the PHY or Switch as appropriate.

2008-12-13[ARM] dma: correct dma_supported() implementationRussell King
dma_supported() is supposed to indicate whether the system can support the DMA mask it was passed, which depends on the maximal address which can be returned for DMA allocations.

2008-12-11[ARM] Kirkwood: properly handle the WAN port on newer RD88F6281 boardsRonen Shitrit
On newer versions of the RD88F6281 board, the WAN port is connected to its own ethernet port on the CPU, via a separate PHY, whereas on older versions of the board, it is connected to one of the PHYs in the ethernet switch. In the RD8F6281 setup code, detect which version of the board we are running on, and instantiate the ethernet ports and switch driver accordingly.

2008-12-10ARM: OMAP2: skip unnecessary TLDR write during non-autoreload for gptimerPaul Walmsley
The GPTIMER TLDR register does not need to be written if the GPTIMER is not in autoreload mode. This is the usual case for dynamic tick-enabled kernels. Simulation data indicate that skipping the read that occurs as part of the write should save at least 300-320 ns for each GPTIMER1 timer reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write posting is enabled.) Skipping the write itself probably won't have much impact since it should be posted on the OCP interconnect. Tested on 2430SDP and 3430SDP.
