* MIPS: Alchemy: Clean up GPIO registers and accessorsManuel Lauss2011-05-192-2/+2
| | | | | | | | | | | | | | | | | | | | | | remove au_readl/au_writel, remove the predefined GPIO1/2 KSEG1 register addresses and fix the fallout in all boards and drivers. This also fixes a bug in the mtx-1_wdt driver which was introduced by commit 6ea8115bb6f359df4f45152f2b40e1d4d1891392 ("Convert mtx1 wdt to be a platform device and use generic GPIO API") before this patch mtx-1_wdt only modified GPIO215, the patch then used the gpio resource information as bit index into the GPIO2 register but the conversion to the GPIO API didn't realize that. With this patch the drivers original behaviour is restored and GPIO15 is left alone.

* MIPS: Alchemy: use 36bit addresses for PCMCIA resources.Manuel Lauss2010-02-278-83/+83
| | | | | | | | | | | | | | | | | | | | | | | On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus area. Currently, addresses at the far end of the 32bit area are assumed to belong to the PCMCIA area and fixed up to the real 36bit address before being passed to ioremap(). A previous commit enabled 64 bit physical size for the resource datatype on Alchemy and this allows to use the correct 36bit addresses when registering the PCMCIA sockets. This patch removes the 32-to-36bit address fixup and registers the Alchemy demo board pcmcia socket with the correct 36bit physical addresses. Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet card.

IRQ numbers need no longer be hidden behind a CONFIG_SOC_AU1XXX symbol: step 1 in my quest to make the Alchemy code less reliant on a hardcoded subtype. This patch also renames the GPIO irq number constants. It's really an interrupt line, NOT a GPIO number! Code which relied on certain irq numbers to have the same name across all supported cpu subtypes is changed to determine current cpu subtype at runtime; in some places this isn't possible so a "compat" symbol is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the current sysctl-based suspend interface with a new sysfs- based one which also uses the Linux-2.6 suspend model. To configure wakeup sources, a subtree for the demoboards is created under /sys/power/db1x: sys/ `-- power `-- db1x |-- gpio0 |-- gpio1 |-- gpio2 |-- gpio3 |-- gpio4 |-- gpio5 |-- gpio6 |-- gpio7 |-- timer |-- timer_timeout |-- wakemsk `-- wakesrc The nodes 'gpio[0-7]' and 'timer' configure the GPIO0..7 and M2 bits of the SYS_WAKEMSK (wakeup source enable) register. Writing '1' enables a wakesource, 0 disables it. The 'timer_timeout' node holds the timeout in seconds after which the TOYMATCH2 event should wake the system. The 'wakesrc' node holds the SYS_WAKESRC register after wakeup (in hex), the 'wakemsk' node can be used to get/set the wakeup mask directly. For example, to have the timer wake the system after 10 seconds of sleep, the following must be done in userspace: echo 10 > /sys/power/db1x/timer_timeout echo 1 > /sys/power/db1x/timer echo mem > /sys/power/sleep This patch also removes the homebrew CPU frequency switching code. I don't understand how it could have ever worked reliably; it does not communicate the clock changes to peripheral devices other than uarts.

* MIPS: Alchemy: update core interrupt code.Manuel Lauss2009-01-117-39/+53
| | | | | | | | | | | | | | | | | | | | | | | This patch attempts to modernize core Alchemy interrupt handling code. - add irq_chips for irq controllers instead of irq type, - add a set_type() hook to change irq trigger type during runtime, - add a set_wake() hook to control GPIO0..7 based wakeup, - use linux' IRQF_TRIGGER_ constants instead of homebrew ones, - enable GENERIC_HARDIRQS_NO__DO_IRQ. - simplify plat_irq_dispatch - merge au1xxx_irqmap into irq.c file, the only place where its contents are referenced. - board_init_irq() is now mandatory for every board; use it to register the remaining (gpio-based) interrupt sources; update all boards accordingly. Run-tested on Db1200 and other Au1200 based platforms.

* MIPS: Alchemy: move commandline mangling out of common codeManuel Lauss2009-01-116-11/+108
| | | | | | | | | | | Not every alchemy-based board might want these options forced on it, and most of this stuff seems to be intended for devboard code anyway. Remove commandline mangling code out of common chip code and instead add relevant sections to all in-tree boards to not change existing behaviour.

| | | | | | | | | | | | | | | | | | | | | | | Share some code and merge small files: - Extract the prom init code from all devboard files (they only differ in memory configuration). - Merge the irq configuration into board setup code. - Merge smaller files into board setup code.
