|/ | | | | | | | | | | | Management of external interrupts has changed but the non-DT code has not integrated these changes. Add a mask to pass external irq specification from SoC specific code to the at91_aic_init() function.

* ARM: at91: add AIC5 supportLudovic Desroches2012-07-021-0/+2
| | | | | | | | | | | | | The number of lines of AIC5 has increased from 32 to 128. Due to this increase, a source select register has been introduced for the interrupt line selection. Moreover, register mapping has been changed. For that reasons, we need some dedicated callbacks for AIC5. Power management is also concerned by these changes. On suspend, we can't get the whole interrupt mask register as before, we have to read this register 128 times. To reduce this overhead, a snapshot of the whole IMR is maintained.

* ARM: at91: drop at91_set_serial_consoleJean-Christophe PLAGNIOL-VILLARD2012-04-171-11/+0
| | | | | | | | | | | at91_set_serial_console is used to define the default console of linux. This is already manage by the cmdline. And if the boot loader can not be modified you can still set it by enabling the CONFIG_CMDLINE_EXTEND option. And then the command-line arguments provided by the boot loader will be appended to the default kernel command string.

* ARM: at91: AIC and GPIO IRQ device tree initializationNicolas Ferre2012-03-011-0/+6
| | | | | | | | | | | | | | | | Both AIC and GPIO controllers are now using the standard of_irq_init() function to initialize IRQs in case of DT use. The DT specific initialization functions are now separated from the non-DT case and are now using "linear" irq domains. The .map() irqdomain operation is responsible for positioning the IRQ handlers. In AIC case, the Linux IRQ number is directly programmed in the hardware to avoid an additional reverse mapping operation. The AIC position its irq domain as the "default" irq domain. For DT case, the priority is not yet filled in the SMR. It will be the subject of another patch. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

* [ARM] 4739/1: at91sam9263: make gpio bank C and D irqs workDavid Brownell2008-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | On the at91sam9263, IRQs for GPIO banks C and D don't currently work. This is because banks C, D, and E share one clock and toplevel IRQ, but the AT91 code setting up and handling GPIO IRQs expects no sharing. This patch: - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are shared like on sam9263 chips, by setting up a list of those banks and making the IRQ dispatching logic scan that list. - Precomputes the address of each bank's registers, saving it with other per-bank data so that it no longer needs to be constantly recomputed during IRQs and other GPIO operations. That shrinks hot-path code, while helping the GPIO bank irq updates. - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just means "use the default", which is "both edges" here).
