2011-10-08ARM: pxa: use correct __iomem annotationsArnd Bergmann
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.

2011-06-24ARM: pm: pxa: move cpu_suspend into C codeRussell King
We don't need a veneer for cpu_suspend, it can be called directly from C code now. Move it into the PXA CPU suspend functions, along with the accumulator register saving/restoring. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-04-24ARM / PXA: Use struct syscore_ops for "core" power managementRafael J. Wysocki
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.

2011-04-13ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio()Eric Miao
This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup event. It is misinterpreted as a gpio irq not a PWER bitmask. Fixed this by converting the incorrect IRQ_TO_IRQ() to a correct version of irq_to_gpio(). Reported-by: Nick Bane <nickbane1@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

2010-12-16ARM: pxa: Access SMEMC via virtual addressesMarek Vasut
This is important because on PXA3xx, the physical mapping of SMEMC registers differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx and PXA320, the PCMCIA driver was adjusted accordingly as well. Also, various places in the kernel had to be patched to use __raw_read/__raw_write.

2010-02-12ARM: Consolidate clks_register() and similarRussell King

2009-12-01[ARM] pxa: allow platforms to control which uarts are registeredRussell King
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.

2009-03-09[ARM] pxa: move IRQ handling of GPIO 0 and 1 outside of gpio.cEric Miao
This is part of the work making gpio.c generic enough, the changes include: 1. move IRQ handling of GPIO 0 and 1 outside (and back into irq.c) 2. pxa_init_gpio() accepts a range for muxed GPIO IRQs, and an IRQ number for the muxed GPIOs 3. __gpio_is_occupied() and __gpio_is_inverted() are made inline, and are moved into <mach/gpio.h> instead of generic gpio.c Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-03-09[ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usageEric Miao
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>

2008-12-02[ARM] pxa: add support for additional GPIOs on PXA26xEric Miao
Original patch from Marek Vasut, the problems with PXA26x are: 1. there are additional 4 GPIOs 86,87,88,89 have their direction bits inverted in GPDR2, as well as their alternate function bits being '1' for their GPIO functionality in GAFRx 2. there is no easy way to decide if the processor is a pxa26x or a pxa250/pxa255 at run-time, so the assumption here is the pxa26x will be treated as one of the pxa25x variants, and board code should have a better knowledge of the processor it is featured Introduce pxa26x_init_irq() for the second purpose, and treat the additional GPIOs > 85 on PXA25x specially. Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code a bit when PXA26x support isn't needed. Board config options have to select this to enable the support for PXA26x. __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x isn't selected.
