add-skip_filter-s3c2410_ts.patch
Skip filter for touchscreen values.
Problem: The first and the last sample might be unreliable. We provide
this filter as a separate function in order to keep the event_send_timer_f
function simple. This filter:
* Skips NHEAD points after IE_DOWN
* Skips NTAIL points before IE_UP
* Ignores a click if we have less than (NHEAD + NTAIL + 1) points
Right now the filter is embedded in the driver. We have two #defines with
the parameters SKIP_NHEAD and SKIP_NTAIL. I didn't store their values in
struct skip_filter on purpose.

When we are informed by UDC stuff that we have been enumerated as
a gadget, we recorded the new current limit but then did nothing.
It meant that on boot, the enumeration happened but we remained
stuck at 100mA current limit. This patch provokes a call to the
work queue to change the current limit and means that coldplugged
USB to a PC now recognizes it can pull 500mA when enumerated.

This moves the backlight init to right before the backlight device init
during the jbt6k74 probe callback... it guarantees video is up and the lcm
is configured before we bring up backlight and so removes the white flash
during boot, the all-black framebuffer is instead shown smoothly and
cleanly.

fix-last_issued-ts_filter_median.patch
- Decimation_below was not being used in the median filter. Fixed.
- Decimation_below should be small. There's no need to change many
points in the median filter if we're moving slow. In this way we
will filter more noise.
- Now we deliver 2X input events -- 1 each 5 milliseconds.
(side effect of the previous two changes)
- We should omit the last point before the UP event but I think this
belongs to user-space. I'm programming a tslib filter ("skip") and
if it doesn't work will I'll send a patch later to skip the last
point in the driver.

Changes related to pcf50633_mfd.patch
|
|
1. Removes pmu_voltage_rails stuff and replaces it with regulator_init_data[]
2. Removes voltage_ldoX and other /sys attributes.
3. Introduces s3c2410_pm_begin method to call regulator_suspend_prepare()
|
|
Change the pm_gps driver to use the regulator API.
|
|
Changes the glamo-mci driver to use the regulator API.
|
|
Move backlight support out of pcf50633 driver. backlight
support now uses corgibl aka generic backlight support.
Set
CONFIG_BACKLIGHT_CORGI=y to use it.
|
|
Specify regulator constraints for gta02. For now, constraints for only
the current used devices are specified.
|
|
Eliminate pcf50633_global and hence make pcf50633.c work with
multiple devices. pcf50633 is no longer a paltform device, but
an i2c device.

Merge in the accelerometer functionality from stable
From: Simon Kagstrom <simon.kagstrom@gmail.com>
This giant patch merges the functionality from stable. It also changes
the default threshold to 0 (generate interrupts on data). As the
level-triggered interrupts cause too frequent interruptions on low
thresholds, also set a lower limit to 36mg to avoid slowing down the
phone too much.
Also rearrange the probe function to disable interrupts only over device
I/O. This fixes the kernel errors when inserting the module.
Andy was right: In stable-tracking, no magic workaround is needed to
make suspend/resume work. I've tested the accelerometers under heavy
load (making the phone basically unusable) without getting lockups.

Make accelerometers work again in stable-tracking.
They stopped working with a previous commit.
(shifter >> 7) & 1); ...; shifter <<= 1;
Had been changed to:
(shifter >> (7 - n)) & 1) /* assuming tx_bytes == 1 */
The problem: an unneeded shifter <<= 1 was still there.
We make a small change to the indexing code to make things work again.

This large patch removes motion sensor from Linux SPI bitbang driver.
Previously, some access was done through Linux SPI protected
by a mutex, and the ISR access was done by platform bitbang code due
to inability of Linux SPI driver to work in the interrupt context.
Now all access is done by bitbang callbacks in mach_gta02.c and are
protected by single scheme of interrupt lockout for the duration --
I line-by-line'd the driver to confirm that best I could, adding
protection and taking more care on several /sys related paths.
Because this is no longer a Linux SPI bus driver, the path for various
/sys things have changed. They can now be found down, eg,
/sys/devices/platform/lis302dl.1/sample_rate
lis302dl.1 is the top sensor and .2 the bottom. The names of the input
susbsytem paths remain the same as before.
Not working in interrupt context made trouble using interrupt lockout as
locking

Rather than using conservative default timings for the NAND flash,
use the timings as specified in the S3C2442B MCP data sheet.

This patch carries over the OpenMoko modifications at
include/asm-arm/arch-s3c2410/spi-gpio.h to
arch/arm/mach-s3c2410/include/mach/spi-gpio.h
Note: board_size and board_info have been removed upstream, but as we
still rely on them we'll just put them back for now. These will need to
be removed (and the corresponding driver changes made, of course) before
this can go upstream.
