2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King1-9/+0
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-29[ARM] iop3xx: avoid polluting the kernel's namespaceRussell King4-7/+3
Avoid unnecessarily pollution of the kernel's namespace by avoiding mach/hardware.h in mach/io.h, mach/memory.h and mach/timex.h. Include this header file where necessary. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre1-11/+0
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King6-6/+6
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-07-23leds: Add pca9532 platform data for Thecus N2100Riku Voipio1-0/+52
Thecus N2100 has leds and a buzzer attached to a pca9532 controller. Attach the driver to the i2c bus and define the pca9532 pin coniguration for this platform in n2100_leds. With this patch, support for N2100 should be complete in mainline Linux.

2008-04-30i2c: Convert most new-style drivers to use module aliasingJean Delvare3-8/+3
Based on earlier work by Jon Smirl and Jochen Friedrich. Update most new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. I've left the video drivers apart (except for SoC camera drivers) as they're a bit more diffcult to deal with, they'll have their own patch later.

This patch is required, in conjunction with the patch submitted to linux-mtd [1], to access the flash memory device in the GLAN Tank. Without the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 ... physmap-flash physmap-flash.0: map_probe failed whereas with the patches, the boot log shows physmap platform flash device: 00080000 at f0000000 Found: ST M29W400DB physmap-flash.0: Found 1 x16 devices at 0x0 in 16-bit bank number of JEDEC chips: 1 cfi_cmdset_0002: Disabling erase-suspend-program due to code brokenness. ... cmdlinepart partition parsing not available Searching for RedBoot partition table in physmap-flash.0 at offset 0x70000 No RedBoot partition table detected in physmap-flash.0 The change made by this patch is required because the ST M29W400DB flash memory chip in the GLAN Tank is used in 16 bit bus mode (~BYTE pin is high when the board is powered on).

2007-05-03[ARM] 4348/4: iop3xx: Give Linux control over PCI initializationDan Williams3-5/+17
Currently the iop3xx platform support code assumes that RedBoot is the bootloader and has already initialized the ATU. Linux should handle this initialization for three reasons: 1/ The memory map that RedBoot sets up is not optimal (page_to_dma and virt_to_phys return different addresses). The effect of this is that using the dma mapping API for the internal bus dma units generates pci bus addresses that are incorrect for the internal bus. 2/ Not all iop platforms use RedBoot 3/ If the ATU is already initialized it indicates that the iop is an add-in card in another host, it does not own the PCI bus, and should not be re-initialized.

An iq80219 is a board with an iq31244 layout and an 80219 processor. It breaks the current assumption that all 80219 processors run on ep80219 platforms. This patch adds the "force_ep80219" option to the kernel to override boot loaders that have passed in the iq31244 id, and adds the MACHINE_START definition for ep80219.
