2009-12-07power: implement platform battery driverPaul Fertser
This driver can be used for dumb batteries when all knowledge about their state belongs to the platform that does necessary ADC readings, conversions, guessimations etc. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-12-06s3c24xx-pmw: Add suspend/resume support.Lars-Peter Clausen
2009-12-06S3C: Allow to completly disable low-level messagesLars-Peter Clausen
In some cases it is desirable to completly disable low-level messages. For example if you have no uart available for a serial console. With this patch it is possible to disable low-level messages by setting CONFIG_S3C_LOWLEVEL_UART_PORT to less then zero. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06s3c: Register gpio bank J with gpiolibLars-Peter Clausen
This is nonportable and wastes a lot of memory and thus should be replaced with a prober solution asap.
2009-12-06s3c2410_udc-2440_dual_packet-workaround.patchmokopatches
This is a patch that seems to make the USB hangs on the S3C2440 go away. At least a good amount of ping torture didn't make them come back so far. The issue is that, if there are several back-to-back packets, sometimes no interrupt is generated for one of them. This seems to be caused by the mysterious dual packet mode, which the USB hardware enters automatically if the endpoint size is half that of the FIFO. (On the 2440, this is the normal situation for bulk data endpoints.) There is also a timing factor in this. I think what happens is that the USB hardware automatically sends an acknowledgement if there is only one packet in the FIFO (the FIFO has space for two). If another packet arrives before the host has retrieved and acknowledged the previous one, no interrupt is generated for that second one. However, there may be an indication. There is one undocumented bit (none of the 244x manuals document it), OUT_CRS1_REG[1], that seems to be set suspiciously often when this condition occurs. There is also CLR_DATA_TOGGLE, OUT_CRS1_REG[7], which may have a function related to this. (The Samsung manual is rather terse on that, as usual.) This needs to be examined further. For now, the patch seems to do the trick. Note that this is not a clean solution by any means, because we might potentially get stuck in that interrupt for quite a while.
2009-12-06mtd: s3c2410_nand: Add config option to disable hw ecc at runtimeHolger Freyther
This patch adds a flag to the s3c2410_nand platform data, which configures whether hardware ecc is used for that chip. Currently hardware ecc is used if it was compiled into the kernel. But if you want to build a kernel which runs on multiple devices you might have a configuration where you have devices which require hw ecc as well as devices which want software ecc.

2009-12-06s3c24xx: Add number of board irqs for the gta02Lars-Peter Clausen
The gta02 uses the glamo mfd driver which requires 9 board irqs. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06s3c24xx: Add support for board IRQsLars-Peter Clausen
Some boards have a need for a set of extra IRQ numbers, for example some multifunction devices which do irq demultiplexing require them. This patch adds S3C2410_BOARD_NR_IRQS which specifies the number of extra board IRQs. Board specific code would use S3C2410_BOARD_IRQ_START to get the number of it's first irq. Since it is possible to support a multiple boards with a single kernel and there is no easy way to set a CONFIG option to multiple values and only use the maximum each board which needs board IRQs has do be explicitly added to irqs.h Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-06gta02: Disable hardware ECC unless we get instructed to enable itHolger Freyther
Early verions off uboot used for the gta02 flashed the nand with ecc information incompatible to s3c2442 hardware ecc. Disable hardware error correction by default, unless the bootloader explicitly enables it. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-06ARM: gta02: Add gpio bank B quirk for hardware revision 5 and earlierLars-Peter Clausen
On hardware revision 5 and earlier the leds found on the gta02 are missing a resistor and reading their gpio pin status will always return 0. So we have to shadow the led states in software. This is done by "hijacking" the gpio accessor functions for bank B. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06ARM: gta02: Add LED supportLars-Peter Clausen
The gta02 has three leds which are connected though gpio pins and thus can get supported by using the generic leds-gpio driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06ARM: gta02: Add button supportLars-Peter Clausen
The gta02 has two buttons which are connected to gpio pins and thus can get supported by using the generic gpio-keys driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-06backlight/mfd: Add pcf50633 backlight driverLars-Peter Clausen

2009-12-06MFD: pcf50633: Fix bitfield logic in interrupt handlerLars-Peter Clausen
As those constans are alread bitfields it's wrong Those constants are already bitfields.
2009-12-06mfd: pcf50633: Fix pcf50633-regulator drvdata usageLars-Peter Clausen
Currently the pcf50633-regulator driver data is set to the pcf50633 core structure, but the pcf50633-regulator remove handler assumes that it is set to the regulator device. This patch fixes the issue by accessing the pcf506533 core structure through its parent device and setting the driver data to the regulator device. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Use platform_device_add_data to set regulator platform dataLars-Peter Clausen
Platform devices allocated with platform_device_alloc should use platform_device_add_data to set the platform data, because kfree will be called on the platform_data when the device is released. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Cleanup pcf50633_probe error handlingLars-Peter Clausen
Currently the child devices were not freed if the irq could not be requested. This patch restructures the function, that in case of an error all previously allocated resources are freed. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen
Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-06mfd: pcf50633 disable unnecessary shutdown on lowsysPaul Fertser
On gta02 hardware revision A5 it can actually bring the system down during normal operating conditions so we disable it. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-12-06power: pcf50633: query charger status directlyPaul Fertser
Current scheme is fragile and is likely to go off sync, especially on batfull->adapter charging automatic MBC transition. Query the status bit every time we need it instead. We need to export another function to query for USB presence because we can't read anything from PCF50633 (via I2C) inside irq context and that is needed by usb gadgets. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-12-06power: pcf50633: properly reenable charging when the supply conditions changePaul Fertser
If chgmod == BATFULL, setting chgena has no effect. Datasheet says we need to set resume instead but when autoresume is used resume doesn't work. Clear and set chgena instead. This enables a user to force charging by re-plugging USB even when the charger entered Battery Full mode, might be handy before a long trip. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-12-06power: pcf50633: get rid of charging restart software auto-triggeringPaul Fertser
After reaching Battery Full condition MBC state machine switches back into charging mode when the battery voltage falls below 96% of a battery float voltage. The voltage drop in Li-Ion batteries is marginal (1-2%) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 75-80%. That is a desired behaviour recommended by battery manufacturers, don't mess with it. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-12-06rtc: pcf50633: manage RTC alarm "pending" flagWerner Almesberger
This patch adds setting and clearing of the "pending" flag of the RTC alarm. The semantics follow the UEFI specification 2.2 available at http://www.uefi.org/specs/, i.e., the "pending" flag is cleared by disabling the alarm, but not by any other condition (such as the passing of time, a successful wakeup, or setting of a new alarm.)
