2009-01-21fix GPS resume if powered on previouslyVladimir Koutny
Fix re-enabling of GPS on resume The call to gps_pwron_set(0) during suspend would clear power_was_on flag so the on/off status was always lost. Additionally when enabling/ disabling the regulator check its actual state, not power_was_on flag (they don't match on resume). Signed-off-by: Vladimir Koutny <vlado@ksp.sk>

2009-01-20RFC: don't aggravate kernel panicsWerner Almesberger
When in a kernel panic, we try to turn on the backlight. Because of the panic, preempt is disabled at that time. Unfortunately, operating the backlight requires access to I2C, and I2C likes to sleep. All this results in the kernel unleashing a nearly endless flood of complaints complete with stack traces, etc., which often obscures the real issue. This patch is one way to improve the situation: it just skips touching the backlight if we're in an atomic context. However, it isn't perfect: it would be desirable if the backlight did get turned on also on a panic. To do so, we would need to use I2C in a way that doesn't sleep. So I wonder if this is good enough or if someone has any plans to make a better solution ? Signed-off-by: Werner Almesberger <werner@openmoko.org>

2009-01-19clean up GTA02 WLAN power controlWerner Almesberger
This patch cleans up the GTA02 WLAN power control platform device: - remove misleading /sys/devices/platform/gta02-pm-wlan.0/power_on Users really wishing to play with reset can just gpio j12=0 - rename gta02_wlan_power to gta02_wlan_reset, because that's what it truly is - remove handling of GTA02_CHIP_PWD because - it's not used, say our schematics - even if it is, it's sampled long before we could affect it - move SDIO-specific conversion from "power switch" to "reset button" logic from gta02_wlan_reset to gta02_s3c_mmc_set_power - removed mutex protection because we now only have a single user A note in passing: we can probably do away with gta02_pm_wlan completely once upstream rfkill adds better support for type-based control.

2009-01-19make neo1973_pm_gps.c suck lessWerner Almesberger
Here's a bunch of changes to neo1973_pm_gps.c. The thing I set out to change was just the initial power state, but there's so much wrong in there, I couldn't resist slaying some evil on the way: - update the copyright year - show slightly more confidence in operator precedence - simplify #ifdef rat's nest a little - rename "pwron" sysfs file to "power_on", to conform to all the rest - wrap lines longer than 80 columns - use PTR_ERR, not cast - reduce redundancy and increase readability in code patching gta01_gps_sysfs_entries - on GTA02 and if booted by u-boot, GPS is powered on. Power it off, like on GTA01 or with Qi. It's still nasty, but slightly less painful to look at now. Tested on GTA02 and tested that it still compiles for GTA01. The name change from "pwron" to "power_on" may be controversial. If this causes undue misery for distribution makers, please holler. Signed-off-by: Werner Almesberger <werner@openmoko.org>

The driver does not directly implement an rfkill device but uses the help of a special platform device, such that the latter can retain rfkill state when the AR6k driver is removed (e.g., because of suspend). If an attempt is made to bring the driver up (module load, bind, or resume) while rfkill is blocking, only the driver's data structures are initialized, but function activation and most of the rest of the setup is deferred until the rfkill block is removed.

2009-01-12Change AR6k driver to module and remove CONFIG_MDWerner Almesberger
This patch changes the two GTA02 default configurations[1] to build the AR6k driver and S3C MCI (which is used exclusively by AR6k) as modules. This way, WLAN can be brought up only if we actually need it. The patch also disables CONFIG_MD, which served no clear purpose. [1] andy removed the moredrivers part despite asking for it because it can be useful to have it built in without syncing the rootfs, so the packaging config alone has it as modules.

The original problem was due to a lost edge. The present problem - When POWER is pressed during the transition, handle_level_irq runs which looks at the IRQ_DISABLED flag set by pcf50633_suspend and masks the irq on chip. Now when the cpu wakes up (level keeps hitting us), s3c_irq_demux_extint8 runs, which tries to handle all pending irqs. But before it does so, it applies the mask and hence not all pending irqs were acked and hence, our pmu's irq (level) caused an irq flood.. This patch clears those interrupts which are masked, but pending. Fixes the problem for me. Mildly tested. Signed-off-by: Balaji Rao <balajirrao@openmoko.org>

This provides a way for code to force a mmc rescan by using the s3c hsmmc platform device as a handle. It solves the issue of 6410 having two card detect signals mutually exclusive on one physical ball. Ben Dooks told he might implement this another way but we need this on GTA03 right now and can migrate it to any official way that turns up. Signed-off-by: Andy Green <andy@openmoko.com>
