MIPS: Alchemy: introduce helpers to access SYS register block.

2014-07-30T11:53:28+00:00

This patch changes all absolute SYS_XY registers to offsets from the SYS block base, prefixes them with AU1000 to avoid silent failures due to changed addresses, and introduces helper functions to read/write them. No functional changes, comparing assembly of a few select functions shows no differences.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle

suspend: constify platform_suspend_ops

2010-11-16T13:14:02+00:00

While at it, fix two checkpatch errors. Several non-const struct instances constified by this patch were added after the introduction of platform_suspend_ops in checkpatch.pl's list of "should be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73). Patch against mainline. Inspired by hunks of the grsecurity patch, updated for newer kernels. Signed-off-by: Lionel Debroux Acked-by: Ingo Molnar Signed-off-by: Jiri Kosina

MIPS: Alchemy: devboard PM needs to save CPLD registers.

2010-02-27T11:53:41+00:00

Save/restore CPLD registers when doing suspend-to-ram; this fixes issues with harddisk and ethernet not working correctly when resuming on DB1200. Signed-off-by: Manuel Lauss To: Linux-MIPS Patchwork: http://patchwork.linux-mips.org/patch/986/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: devboards: Convert to gpio calls.

MIPS: Alchemy: new userspace suspend interface for development boards.

2009-01-11T09:57:27+00:00

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.
