* ARM / PXA: Use struct syscore_ops for "core" power managementRafael J. Wysocki2011-04-24
| | | | | | | | | | | | | 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: Introduce pxa{25x,27x,3xx}_map_io()Marek Vasut2010-12-16
| | | | | | | | | | | 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: pxa: reduce the scope of get_memclk_frequency_10khz()Haojian Zhuang2010-10-09
| | | | | | | | | | | | Up to now, only pxa2xx pcmcia driver is using the API. No other device driver is using this API in PXA3xx or any other PXA silicons. Restrict the scope only on pxa2xx and remove the implementation of pxa3xx. So we can avoid oo much checking on cpuid after more pxa chips supported.

* ARM: Remove DISCONTIGMEM supportRussell King2010-07-16

* [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>
* [ARM] pxa: better MFP low power state support for pxa25x/pxa27xEric Miao2008-09-26
| | | | | | | | | | | | | When configured as a specific low power state: MFP_LPM_DRIVE_LOW, MFP_LPM_DRIVE_HIGH, the corresponding GPDR register bit during low power mode shall be re-configured as output (if they are not configured so), thus the PGSRx bits can output. Create an additional low power values GPDR registers, and properly save/restore the GAFR + GPDR registers when doing suspend/resume.

* [ARM] pxa: introduce reset_status and clear_reset_status for driver's usageEric Miao2008-08-04
| | | | | | | | | | | | Due to the problem of reset status bits being handled by different registers between pxa2xx and pxa3xx, introduce a global reset_status variable, initialized by SoC-specific code and later being used by other drivers. And also introduce clear_reset_status(), which is used to clear the corresponding status bits. Pass RESET_STATUS_ALL to clear all bits. Signed-off-by: Eric Miao <eric.miao@marvell.com>

* [ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao2008-04-19
| | | | | | | | | | | | | | | | | | | | | This makes the code better organized and simplified a bit. 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). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variableeric miao2007-10-12
| | | | | | | | | | | | | | | This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
