| * arm/pxa2xx: reorgazine SSP and SPI header filesSebastian Andrzej Siewior2010-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PXA-SPI driver relies on some files / defines which are arm specific and are within the ARM tree. The CE4100 SoC which is x86 has also the SPI core. This patch moves the ssp and spi files from arm/mach-pxa and plat-pxa to include/linux where the CE4100 can access them. This move got verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com>
* | ARM: pxa: Introduce pxa{25x,27x,3xx}_map_io()Marek Vasut2010-12-161-1/+1
|/ | | | | | | | | | | This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish between PXA25x/PXA27x and PXA3xx memory mapping. Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io() and pxa3xx_map_io() is included.

* arm: remove machine_desc.io_pg_offst and .phys_ioNicolas Pitre2010-10-201-2/+0
| | | | | | | | | | | | | | | Since we're now using addruart to establish the debug mapping, we can remove the io_pg_offst and phys_io members of struct machine_desc. The various declarations were removed using the following script: grep -rl MACHINE_START arch/arm | xargs \ sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }' [ Initial patch was from Jeremy Kerr, example script from Russell King ] Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Acked-by: Eric Miao <eric.miao at canonical.com>

* [ARM] pxa: allow platforms to control which uarts are registeredRussell King2009-12-011-0/+4
| | | | | | | | | | | | | | | | | | For some platforms, it is inappropriate to register all PXA UARTs. In some cases, the UARTs may not be used, and in others we may want to avoid registering the UARTs to allow other drivers (eg, FICP) to make use of the UART. In addition, a while back there was a request to be able to pass platform data to the UART driver. This patch enables all of this by providing functions platforms can call to register each individual UART.

* [ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usageEric Miao2009-03-091-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Considering the header mess ATM, it is not always possible to include the correct header files within board code. Let's keep this simple: <mach/pxa25x.h> - for pxa25x based platforms <mach/pxa27x.h> - for pxa27x based platforms <mach/pxa300.h> - for pxa300 based platforms <mach/pxa320.h> - for pxa320 based platforms <mach/pxa930.h> - for pxa930 based platforms NOTE: 1. one header one board file, they are not compatible (i.e. they have conflicting definitions which won't compile if included together). 2. Unless strictly necessary, the following header files are considered to be SoC files use _only_, and is not recommended to be included in board code: <mach/hardware.h> <mach/pxa-regs.h> <mach/pxa2xx-regs.h> <mach/pxa3xx-regs.h> <mach/mfp.h> <mach/mfp-pxa2xx.h> <mach/mfp-pxa25x.h> <mach/mfp-pxa27x.h> <mach/mfp-pxa3xx.h> <mach/mfp-pxa300.h> <mach/mfp-pxa320.h> <mach/mfp-pxa930.h> Signed-off-by: Eric Miao <eric.miao@marvell.com>

* [ARM] pxa: separate GPIOs and their mode definitions to pxa2xx-gpio.heric miao2008-04-191-0/+1
| | | | | | | | | | | | | two reasons: 1. GPIO namings and their mode definitions are conceptually not part of the PXA register definitions 2. this is actually a temporary move in the transition of PXA2xx to use MFP-alike APIs (as what PXA3xx is now doing), so that legacy code will still work and new code can be added in step by step Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4744/1: pcm027: add support for phyCORE-PXA270 CPU moduleRobert Schwebel2008-01-281-0/+216
This patch adds main support for the generic phyCORE-PXA270 CPU module (aka PCM-027). Its as generic as possible to support any kind of baseboard. Note: Neither the CPU module nor the pcm027.c implementation can work without a baseboard support. Baseboard support can be added by the PCM-990 or any custom variant. V2: After comments by Eric Miao: - Currently unsupported devices moved into separate patch - direct call of baseboard initialisation V3: After comments by Russell King - sort include files - setting RTC bit for power control removed - style problems fixed (discovered by checkpatch.pl) Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
