Changes related to pcf50633_mfd.patch
|
|
pcf50633 driver rewritten to use the MFD model.
|
|
Move the RTC subdevice driver into drivers/rtc/rtc-pcf50633.c
|
|
Introduces pcf50633_read and pcf50633_write for reading a block of
registers. Assumes mutex held by caller.
|
|
We don't need to save state when we suspend as we don't put the PMU to
standby.
This improves the 'resume devices' time from 1.175s to 1.135 sec!
|
|
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.
|
|
Improves ADC access interface in pcf50633 driver.
|
|
Use regulator API for powering on/off the BT device.
|
|
Specify regulator constraints for gta02. For now, constraints for only
the current used devices are specified.
|
|
Modify pcf50633 driver to use the new regulator API.
|
|
Eliminate pcf50633_global and hence make pcf50633.c work with
multiple devices. pcf50633 is no longer a paltform device, but
an i2c device.

|
allow the clock directly through, which means that
we need to update the pwm-clock code to cope with
this.
Add <mach/pwm-clock.h> containing the specific code
to deal with the TCFG divider settings and provide
any other per-arch data that the pwm-clock driver
needs to function.

Setup interrupt latching for thresholded operation
From: Simon Kagstrom <simon.kagstrom@gmail.com>
This patch, for stable-tracking, sets up interrupt latching for
thresholded operation, and also acks the interrupt in the handler. This
reduces the interrupt load, and thresholds < 36 are once again allowed
(though not of much use).
The patch also fixes some warnings in the code (including a potential
bug).
Thanks to Werner for pointing this out!

When compiling s3cmci as a module and doing an insmod-rmmod-insmod
sequence, s3cmci_probe often oopses because the platform data contains
garbage.
The reason for this is that I'm not providing any platform data (removed
in gta02-mmc-mci.patch), and thus s3cmci tries to put its own defaults:
if (!host->pdata) {
pdev->dev.platform_data = &s3cmci_def_pdata;
host->pdata = &s3cmci_def_pdata;
}
s3cmci_def_pdata is inside the module, so the pointer in
pdev->dev.platform_data becomes invalid after the module is unloaded.
Since nothing else in s3cmci uses pdev->dev.platform_data, "patching"
it seems unnecessary. This patch removes it.

This patch adds the module parameter f_max to s3cmci to limit the
maximum clock frequency of the SD interface.
E.g., when booting with s3cmci.f_max=10000000, the kernel should say
s3c2440-sdi s3c2440-sdi: f_max lowered from 50000000 to 10000000 Hz
and the interface frequency should be limited accordingly.
Setting the limit above the maximum frequency supported by the card
or the interface has no effect, so the option is ignored (and no
"f_max lowered" line is printed).
Setting the limit below the minimum frequency supported by the
interface sets it to that frequency.

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.

Export some irq-related functionality to modules
From: Simon Kagstrom <simon.kagstrom@gmail.com>
This patch exports handle_level_irq and __set_irq_handler to modules.
It's needed to compile lis302dl as a module.

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 patch changes the ./build script to generate a uImage.bin file with
the build device appended, eg, uImage-GTA02.bin.
The reason for this change is that it is possible to generate rootfs images
now that can target multiple (and probably increasing numbers of) devices
with the one image. Therefore qi or other bootloader running on the device
is going to have to pick out the right kernel from the rootfs filesystem
for the device it finds it is running on from a set provided down /boot
by the rootfs generator.
/lib/modules for the kernels doesn't get in the way of each other because the
version-specific path is also extended to have the device name as part of it.
2.6.28-GTA02_stable-tracking_c77dda03a7c11666-mokodev
For legacy U-Boot support on GTA01 or GTA02, a symlink to uImage-GTA01.bin or
uImage-GTA02.bin will be needed.
The dfu utility script is updated to take an argument, eg, GTA02

This is probably not correct as the i2c registration is not supposed to
work this way, but for the time being, add this hack to make the GTA01
at least boot. Revisit this and drop this patch when possible.
Thanks to Andy Green for the tip.

Some header files have moved so update #includes.
devs.h has been moved and updated. Delete the old version at
include/asm-arm/plat-s3c24xx as it is no longer used. Nothing to
migrate from this file to the new file at the new location.
s3c_device_i2c has become s3c_device_i2c0

Tacls can actually be zero with some NAND flash devices, so we need
to permit this.
Also, the TACLS register actually specifies the actual number of
HCLK clocks, where the TWRPH0 and TWRPH1 registers are auto-incremented
by one HCLK clock in hardware.

Hi Andy,
I found that stable tracking usb_curlim was zero because of this and the
battery was not getting charged by default.
CONFIG_USB_GADGET_VBUS_DRAW was introduced in .27-rc6 I guess.
