* ARM: pxa: remove irq init from dt machinesRobert Jarzmik2016-09-091-3/+0
| | | | | | | | | | | The init_irq and handle_irq can be declared through standard irqchip declaration and are not necessary in machine descriptions. This is another step towards the generic kernel for the pxa architecture. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: Arnd Bergmann <arnd@arndb.de>

* ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk frameworkRobert Jarzmik2015-05-121-0/+1
| | | | | | | | | | | | | Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. This is the last step of clock framework transition for pxa platforms. It was tested on lubbock (pxa25x), mioa701 (pxa27x) and zylonite (pxa3xx).

* ARM: pxa: change clocks init sequenceRobert Jarzmik2015-05-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since pxa clocks were ported to the clock framework, an ordering issue appears between clocks and clocksource initialization. As a consequence, the pxa timer clock cannot be acquired in pxa_timer, and is disabled by clock framework because it is "unused". The ordering issue is that in the kernel boot sequence : start_kernel() ... time_init() -> pxa_timer() -> here the clocksource is initialized ... rest_init() kernel_init() initcalls -> here the clocks are initialized In the current sequence, the clocks are initialized way after pxa_timer, which cannot acquire the OSTIMER0 clock. To solve this issue, the clocks initialization is moved to pxa_timer(), so that clocks are initialized before clocksource for non device-tree. For device-tree, the standard arm time_init() will take care of the ordering. Reviewed-by: Michael Turquette <mturquette@linaro.org> Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>
* arm: pxa: move init functions into generic.hRobert Jarzmik2014-11-191-23/+42
| | | | | | | | | | | | | | | | | | | | | In order to have a unique .c file for all pxa variants device-tree definitions, all the initialization functions for MACHINE_START and DT_MACHINE_START have been put together into generic.h. The alternative would have been one pxaXXX-dt.c file per variant. The move is necessary because each include/mach/pxaXXX.h includes the variant register descriptions which intersects and conflicts one with each other. The change is a preparation for pxa-dt.c to support multiple pxa, ie. pxa3xx and pxa27x. The machine files including mach/pxaXXX.h all include generic.h, which guarantees no regression should be introduced.

* ARM: delete struct sys_timerStephen Warren2012-12-241-2/+1
| | | | | | | | | | | | | | | | | | Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

* [ARM] pxa: allow platforms to control which uarts are registeredRussell King2009-12-011-0/+5
| | | | | | | | | | | | | | | | | | 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: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao2008-04-191-2/+1
| | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | 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().

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!
