* [ARM] pxa: move pmu device back into mach-pxa/Eric Miao2010-08-05
| | | | | | | | | Not tested and enabled on MMP at this moment, and since the IRQ is different from mach-pxa, I'd prefer to move the PMU device back into mach-pxa/. Will introduce the PMU device to MMP once it's enabled and tested. Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
* ARM: Consolidate clks_register() and similarRussell King2010-02-12
| | | | | | | | | | | | | Most machine classes want some way to register a block of clk_lookup structures, and most do it by implementing a clks_register() type function which walks an array, or by open-coding a loop. Consolidate all this into clkdev_add_table().

* [ARM] pxa: allow platforms to control which uarts are registeredRussell King2009-11-30
| | | | | | | | | | | | | | | | | | 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: move IRQ handling of GPIO 0 and 1 outside of gpio.cEric Miao2009-03-09
| | | | | | | | | | | | | | | 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>

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: add support for additional GPIOs on PXA26xEric Miao2008-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0).

PXA270 sleep: "In sleep mode, all clocks are disabled to the processor and to all peripherals except the RTC."

There are, at least, the following reasons to do that: * 'struct pm_ops' is specifically related to suspend and not to the power management in general. * As long as 'struct pm_ops' is defined in <linux/pm.h>, any modification of it causes the entire kernel to be recompiled, which is unnecessary and annoying. * Some suspend-related features are already defined in <linux/suspend.h>, so it is logical to move the definition of 'struct pm_ops' into there. * 'struct hibernation_ops', being the hibernation-related counterpart of 'struct pm_ops', is defined in <linux/suspend.h> .

* [ARM] 4560/1: pxa: move processor specific set_wake logic out of irq.ceric miao2007-10-12
| | | | | | | | | | | | | a function pxa_init_irq_set_wake() was introduced, so that processor specific code could install their own version code setting PFER and PRER registers within pxa_gpio_irq_type are removed, and the edge configuration is postponed to the (*set_wake) and copies the GRER and GFER register, which will always be set up correctly by pxa_gpio_irq_type() Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
