2009-10-02GTA01/GTA02: disable android drivers in default configsRadek Polak
Android drivers are not needed for standard linux systems. We can save memory by disabling them. Android low memory killer (CONFIG_ANDROID_LOW_MEMORY_KILLER) also prevents using swap by killing applications before swapping can start on non android systems.

2009-10-01Fix s3c-adc suspendVasily Khoruzhick
Fix for a bug that shows when the s3c2410 TS driver requests a conversion from the s3c-adc driver and the machine goes into suspend. In this case the touchscreen stops working. Note: Nelson edited the original patch with a few small changes.

2009-09-23Fix wrong commitNelson Castillo
I'm quite sorry I sent the commit that crashes GTA01. The fix is quite short. Fixing is easier than reverting and fixing conflicts. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net>

2009-09-22s3c24xx: introduce s3c-adc delayVasily Khoruzhick
Without this patch we cannot make the s3c2410/s3c2440 touchscreen driver work. Is this delay device-dependant? Is there a better way to do this? We specify the delay value (S3C2410_ADCDLY).

2009-09-22S3C: ADC: Expose number of remaining conversions to convert callbackNelson Castillo
This patch allow us to efficiently modify the number of remaining conversions from the client side. This us useful when we do not know in advance how many conversions we will need or when we need to cancel pending conversions. This change is simple enough to be compatible with existing code that can just define the new pointer in the callback and ignore it.

2009-08-23Fix max voltage of LDO1Sven Rebhan
This patch fixes a typo in the voltage setting of LDO1. In the function mangle_pmu_pdata_by_system_rev() the value of min_uV is set twice, while the value of max_uV stays at the initialized value. This leaves us with .constraints.min_uV = 3300000 and .constraints.max_uV = 1300000, which is probably not what we want. This patch is only required on andy-tracking.

After suspending with GPS powered on power_on sysfs node reports 0 and GPS is actually unpowered but "echo 1 > power_on" has no effect. This patch fixes it. Reported and analised by Timo Juhani Lindfors <timo.lindfors@iki.fi>, ticket #2293. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-05-25gta01: fix jbt6k74 spi registrationPaul Fertser
Without this jbt6k74 is not seen by the system and consequently display doesn't work with Qi. Rebasing to .28 introduced a regression (probably in a6af63e826b79ae1ba2d8cbfa66805cc2dfe367c) resulting in jbt6k74 no longer manageable by the kernel. This was unnoticed before because u-boot does its own LCM initialization. With Qi it resulted in a white screen. This patch is fixing it by making spi host bus number (unspecified, defaults to 0) and spi device (jbt6k74) bus number match. Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-05-15 This patch adds the option to poll vbus status to the s3c24xx udc driver.Mike Westerhof
Machines that do not route the USB vbus signal to a GPIO can use this mechanism as an alternate way for the udc driver to detect the usb connect/disconnect state, which is useful (for example) to enable the link up/down state to be determined for the g_ether gadget.

2009-04-19remove-ext4-from-gta02_packaging_defconfig.patchMike (mwester)
Removes ext4 support from the packaging defconfig; there is little value in having this built into the kernel, and a bug in the current 2.6.29-rc3 kernel results in the kernel attempting to mount an ext2 rootfs as ext4, which fails. Signed-off-by: Mike Westerhof <mwester@dls.net>
2009-04-16Revert "update gta01 config based on gta02 config"Nelson Castillo
This reverts commit 962780e3631255fc5423192d0762f30a1fa45239. Nothing really wrong with it but the resulting kernel was too big for the GTA01 NAND flash. GTA01 boots.

2009-03-10add primitive camera power controlWerner Almesberger
This dirty hack adds camera activation/deactivation on open/close. This code will have to move to a machine/platform area later. The general driver is the wrong place for it. It also removes the unconditional activation and moves the domain setting to the rest of the power control code. (Thanks, Andy !) Note that opening the camera now always takes about 20 seconds until the settings are downloaded, not just on the first open. Signed-off-by: Werner Almesberger <werner@openmoko.org>
2009-03-10Add filter_chain objectNelson Castillo
Filter chains should be completely opaque to the drivers that use it. We fix this with this patch. ~ Make the "filter chain" a new object. ~ We can build with CONFIG_TOUCHSCREEN_FILTER=n with no problems in a cleaner way. ~ Update s3c2410_ts.c to use the filter_chain object. ~ Cleanups.

2009-03-10Use non-void configurationsNelson Castillo
This patch defines a ts_filter_configuration structure to avoid using void* in the filter initialization, fixing another upstream correction. This also makes the initialization more readable. Tested in GTA02/rev6. Other changes: ~ Comment filter configuration structures. ~ ts_filter.c:ts_filter_chain_create improved. ~ Small cleanups. ~ More TODOs/FIXMEs. ~ Updated GTA02 filter configuration. ~ Updated GTA01 filter configuration. ~ Updated mach-s3c2410/include/mach/ts.h for the new ts. configuration structure. ~ Updated all the filters to use the new configuration structure. ~ Removed MAX_TS_FILTER_CHAIN constant that is no longer needed. No more evil casts left it seems. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net>
2009-03-10Improve filter API and update filtersNelson Castillo
This patch turns upstream feedback into API modifications and code improvements. There will be more patches implementing upstream corrections but this one is the that will make most of the invasive changes and make the most important improvements to the API. Tested in a GTA02/rev06. The goals of this patch are: * Replace recursive calls with iteration. * General code improvements. * Make ts_filter_mean.c a reference for the rest of the filters. * Make the (almost)minimum number of changes to the other filters so that they compile and work, patches for cleaning these up will come next. * Filters should do what they were doing before. Some important changes: * Move "struct ts_filter tsf" in the private structures to force a crash (or break things) if we forget to remove an open-coded cast. * ts_filter.c/ts_filter.h ~ API modifications. * s3c2410_ts.c: ~ Use the new API. ~ Cleanups. * ts_filter_mean.c ~ Replace with a simple mean. ~ Use as a reference for the new API. ~ Move private structure from the .h to the .c. * ts_filter_group.c ~ Update to use the new API. * ts_filter_median.c ~ Update to use the new API. * ts_filter_linear.c ~ Remove functions that are no longer needed. Note: I might leave some TODOs and FIXMEs with this patch. Most of them will be removed shortly. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net>
