2008-11-19[led] Misc fixes in the driver codeHolger Freyther
to_bundle returned the wrong data. The platform_device is the parent of the class_device used by the LED device class. Return the correct class. num_leds was not set to the correct number of registered LEDs. All loops using num_leds (e.g. module unloading) were not executed at all. On removal of the module disable all LEDs. Signed-Off-By: Holger Freyther <zecke@openmoko.org>
2008-11-19[leds] We would enable PWM for all four timers, disable it for all four as wellHolger Freyther
Currently we do not use the PWM code to drive the LEDS. We have enabled the PWM for four timer sources but disable it only for three, fix that up. Signed-Off-By: Holger Freyther <zecke@openmoko.org>

2008-11-19fix-jack-debounce.patchAndy Green
Headphone jack detection is bouncy, it can trigger multiple interrupts on insertion or removal. This patch adds a workqueue that waits out the interrupt spew in 100ms units, and if it sees no more interrupts for 100ms only then samples and reports the jack state. I was unable to get a bounce after 20 or so tries after this. Signed-off-by: Andy Green <andy@openmoko.com>

2008-11-19add-pcf50633-06-RTC_AIE-ioctlHolger Hans Peter Freyther
Hey, the legacy application 'atd' from Russ Nelson/Nils Faerber, used by Qtopia, to schedule alarms currently fails to start as the the above ioctl is failing. The other drivers in drivers/rtc implement the above ioctl and we can implement it too. The code to mask/unmask the RTC alarm is copied from the set_alarm routine and adapted to use the reg_set_bit_mask and reg_set_clear_mask. It is compiling, so it must work. Please welcome me the lkml way ;) Signed-Off-by: Holger Hans Peter Freyther <zecke@openmoko.org>

2008-11-19fix-glamo-mci-defeat-ops-during-suspend.patchAndy Green
We need to be able to use the config option CONFIG_MMC_UNSAFE_RESUME that allows the rootfs to live on SD. But when we use this, it tries to send a reset command to the SD card during suspend -- and unfortunately many things like Power have suspended by then. This patch again rejects IO on the MMC device during suspend of the MMC device, and it gives the result the rootfs on SD card works okay. Signed-off-by: Andy Green <andy@openmoko.com>

2008-11-19introduce-bq27000-battery-driver.patchAndy Green
This is a driver for the bq27000 found in the Highcell A5 battery, and the platform device stuff for it for GTA02. It is a Power Supply Class battery device. The driver doesn't contain an HDQ engine but accepts pointers from the platform data to the HDQ action routines; our platform data plugs it into the FIQ HDQ engine stuff. The Power Supply class exposes the battery down /sys so you can find out battery status by doing the equivalent of this bash command for i in capacity charge_full current_now present status technology temp time_to_empty_now time_to_full_now type voltage_now ; do echo -n "$i " ; cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/$i ; done Here is the kind of result you get from a battery discharging capacity 0 charge_full 1215585 current_now 183375 present 1 status Discharging technology Li-ion temp 276 time_to_empty_now 0 time_to_full_now 3932100 type Battery voltage_now 2761000 Note that temp is in 1/10 degrees C, other values are in uV, uA, uW. The time_to_* reported are bogus, but that is what the battery actually reports. We can make more mappings to entries in power_supply class but this is enough to get started with.

2008-11-19introduce-fiq-hdq.patchAndy Green
This adds a platform driver and device which performs HDQ battery protocol using a single GPIO pin which is set through platform data. HDQ has some hard latency requirements which can't be met if interrupts are enabled, so normally using a GPIO for this will require blocking out all other interrupts and processes for several milliseconds per register being read or written. This HDQ protocol engine is a FSM implemented inside the the FIQ ISR and regulated by timer interrupts happening at 20us intervals. The path through the FSM on any "clock" is very short and should be over with in ~ 1us. Because FIQ has guaranteed latencies of <1us, it means we can service the HDQ protocol without blocking interrupts or any other process other than the caller that is waiting for the result. It's pretty cool performance from 1 GPIO ;-) Due to it being hard to do locking from the FIQ ISR the code simply sleeps 10ms or whatever the scheduler gives it and checks if the transfer took place yet. This platform driver doesn't have any knowledge about the device it is talking to, it just knows it is a HDQ device. It exports three functions for read, write and confirming HDQ is initialized. It also exports two /sys nodes that are usable by humans, one dumps the whole 127 register HDQ register space # cat /sys/devices/platform/gta02-hdq.0/hdq/dump 00 44 55 00 00 00 ba 04 a2 0d 50 00 00 00 00 00 00 00 9a 1a 00 00 ff ff ff ff 29 00 00 00 80 2b 00 00 00 00 00 00 ff ff 00 00 00 00 00 32 af 06 a0 d8 37 4e 00 00 00 00 00 00 00 34 2e 03 b4 e7 00 00 06 00 41 00 4c 02 00 00 00 00 00 00 00 00 83 02 00 00 94 09 59 b9 a5 0d 7f 21 00 00 7a ff df ff 62 ff a7 04 2e 05 00 00 00 01 00 07 00 00 2a 78 36 67 7b b5 1b a9 af 19 38 89 63 57 42 7c # and the other allows to set one register # echo 2 170 > /sys/devices/platform/gta02-hdq.0/hdq/write writes 0xAA into register 2.
