Raw Normal View History

Linux-2.6.12-rc2 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!

[ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into one 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] 4560/1: pxa: move processor specific set_wake logic out of irq.c 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>

gpiolib support for the PXA architecture This adds gpiolib support for the PXA architecture: - move all GPIO API functions from generic.c into gpio.c - convert the gpio_get/set_value macros into inline functions This makes it easier to hook up GPIOs provided by external chips like ASICs and CPLDs.

[ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variable 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().
