PATCH-9_9-gta01-Tweak-pixclock-to-reduce-flicker-with-cpufreq.eml
Experimenting with a GTA01 showed pixclock values near 40000 (after the
rounding caused by the divider calculation) caused visible flicker. Values
near 20000 caused only a slight flicker, and the default value after rounding
with the default HCLK frequency of 133MHz is 30075.
Change the value to 35000 to make it stay in the range 17500-35000 and thus
reduce the flicker a bit.

sdio: use interruptible sleep in kthread main loops
My FreeRunner's load average was leveling off at 2.00 as a result of
these two kernel threads:

This fixes them to use interruptible sleep primitives while waiting in
their main loops, as is conventional for kernel threads. They can't
actually be interrupted since kernel threads ignore all signals, but
by sleeping this way they get classified as long term waiters, and
don't get counted as running for purposes of load average calculation.
This is intended as a minimal fix. In the longer term, it'd probably
make sense to replace the semaphores with completions or something,
and to do away with some of these StudlyCapped wrapper functions.

test-force-gps-voltage-3v6.patch
Allows you to control RF_3V between 3.0V and 3.3V; this increases the
phantom voltage at the internal antenna from 2.63V to 2.85V and may
or may not affect antenna gain and GPS behaviour.
You can read and set the GPS voltage by

introduce-BANKCON-meddling-sysfs.patch
A few questions have been flying around about how optimal
our waitstates are for various things including Glamo.
This patch introduces new sysfs nodes
/sys/devices/platform/neo1973-memconfig.0/BANKCON0
...
/sys/devices/platform/neo1973-memconfig.0/BANKCON7
If you cat them you get translated info about bus speed on
that chip select, eg,
# cat /sys/devices/platform/neo1973-memconfig.0/BANKCON1
BANKCON1 = 0x00000A40
Type = ROM / SRAM
PMC = normal (1 data)
Tacp = 2 clocks
Tcah = 0 clocks
Tcoh = 1 clock
Tacc = 3 clocks
Tcos = 1 clock
Tacs = 0 clocks
You can write them in hex too
# echo 0x200 > /sys/devices/platform/neo1973-memconfig.0/BANKCON1
The write format for BANKCON0 - 5 looks like this
b1..b0 PMC Page Mode Config
b3..b2 Tacp Page Mode Access Cycle
b5..b4 Tcah Address hold after CS deasserted
b7..b6 Tcoh CS hold after OE deasserted
b10..b8 Tacc Access Cycle Period
b12..b11 Tcos CS setup before OE asserted
b14..b13 Tacs Address setup before CS asserted
BANKCON 6 and 7 have two extra bits
b16..b15 MT Memory type (00=ROM/SRAM, 11=DRAM)
If it's ROM/SRAM, the rest of the bits are as described above.
For DRAM
b1..b0 SCAN Column address number
b3..b2 RAS to CAS delay
The patch is intended to let people experiement on their own. But
of course you will crash things for sure if the timing is wrong, and
you can also trash SD Card data if you make Glamo unstable, so remove
it or remount ro first. Other horrible things are possible, but
because the settings aren't sticky, you should always be able to
recover by either normal reboot usually or at worst NOR boot and then
dfu. Most likely you will just crash your session and have to reboot
if your settings are bad, but consider yourself warned bad things are
possible. :-)

change-backlight-level-not-forced-up-on-resume.patch
We at least always enabled backlight on resume, this patch
changes us to set backlight back to last requested backlight
brightness level on resume. Note it means that you can
resume with screen blanked, but it should come back if that
happened with touchscreen action as usual.
/sys/class/backlight/pcf50633-bl/actual_brightness
and
/sys/class/backlight/pcf50633-bl/brightness
seem to agree after resume when reportedly they didn't before.

fix-glamo-suspend-resume-dram-and-engines.patch
Two issues... we never took care to take down engines in suspend
and bring them back in resume. This was part of the display
corruption that could be seen briefly on resume. The other issue
that made the "noise" corruption was bad ordering of resume steps.
This patch simplifies (removing needless re-init) resume actions
and makes explicit the suspend and resume steps. It also adds
code to track which engines are up and push them down in suspend
and bring them back in resume.
The result is no more corruption of display buffer in suspend, it
comes back completely clean.
