* ARM: pxa: use correct __iomem annotationsArnd Bergmann2011-10-081-2/+2
| | | | | | | | | | | This tries to clear up the confusion between integers and iomem pointers in the marvell pxa platform. MMIO addresses are supposed to be __iomem* values, in order to let the Linux type checking work correctly. This patch moves the cast to __iomem as far back as possible, to the place where the MMIO virtual address windows are defined.

* ARM / PXA: Use struct syscore_ops for "core" power managementRafael J. Wysocki2011-04-241-1/+0
| | | | | | | | | | | | | Replace sysdev classes and struct sys_device objects used for "core" power management by the PXA platform code with struct syscore_ops objects that are simpler. This reduces the code size and the kernel memory footprint. It also is necessary for removing sysdevs entirely from the kernel in the future. Signed-off-by: Rafael J.

* ARM: pxa: fix mfpr_sync to read from valid offsetYu Tang2011-02-091-2/+6
| | | | | | | | Since mfpr_mmio_base[0] is not always valid on later SoCs, fixed mpfr_sync() to read back from valid mfp offset always. Signed-off-by: Yu Tang <ytang5@marvell.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

* [ARM] pxa: ensure mfp is in correct range in mfp_{read,write}Roel Kluin2009-11-171-2/+2
| | | | | | | Ensure we do not read/write outside array boundaries with a negative index. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
* [ARM] pxa: add MFP_PULL_FLOATDaniel Mack2009-09-101-0/+3
| | | | | | | | | | | There is currently an uncovered case for MFP configuration on PXAs which is selected by setting the PULL_SEL bit but none of the PULL{UP,DOWN}_EN bits. This case is needed to explicitly let pins float, even if the selected alternate function would default to a configuration with a pull resistor enabled.
