    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.

    PATCH-7_9-Experimental-S3C2410A-cpufreq-driver-serial-.eml
    
    This is the cpufreq notifier for the S3C2410 serial driver.
    
    It uses the hardware flow control, when available, to avoid losing characters
    during the transition.

    PATCH-6_9-s3c2410-serial-move-divisor-calculation-to-separate-function.eml
    
    The cpufreq notifier for the S3C2410 serial driver has to recalculate the
    baud rate divisor. The code which does the calculation is currently part of
    s3c24xx_serial_set_termios. Split it off to a separate function.
    
    Code movement only, no functional changes.

    PATCH-3_9-cpufreq-Warn-whem-cpufreq_register_notifier-called-before-pure-initcalls.eml
    
    If cpufreq_register_notifier is called before pure initcalls,
    init_cpufreq_transition_notifier_list will overwrite whatever it did,
    causing notifiers to be ignored.
    
    Print some noise to the kernel log if that happens.

commit 2afe8eba68d61cb570988f938cfb9081b72d28b7

Date:   Thu Jul 17 10:40:41 2008 +0100

    PATCH-2_9-Experimental-S3C2410A-cpufreq-driver-core-.eml
    
    This is a cpufreq driver for the S3C2410A. It deals only with the main
    frequency switching part and with the SDRAM refresh counter. The rest of the
    hardware should be dealt with via cpufreq notifiers on each of the drivers.
    
    It also has experimental support for the S3C2442.

    PATCH-1_9-cpufreq-fix-show_trans_table.eml
    
    Fix show_trans_table when it overflows PAGE_SIZE.
    
    * Not all snprintf calls were protected against being passed a negative
    length.
    * When show_trans_table overflows, len might be > PAGE_SIZE. In that case,
    returns PAGE_SIZE.

    add-limit-sdcard-clk-cmdline.patch
    
    This patch allows you to control the maximum clock rate that will
    be selected for SD Card access, from the kernel commandline using
    
     glamo_mci.sd_max_clk=10000000
    
    and also from
    
     echo 10000000 > /sys/module/glamo_mci/parameters/sd_max_clk
    
    although you have to suspend and resume to make the limit operational
    on the actual SD_CLK line.
    
    Clocks that are possible are divided down from ~50MHz, so 25000000,
    16666666, 12500000, 10000000, etc.  With Freerunner A5 revision that
    has 100R series resistors in SD Card signals, I didn't get reliable
    operation above 16MHz.  With A6 revision the series resistors went
    down to 75R, maybe it can work at 25MHz.
    
    Reducing the clock rate is something to try if you find that your
    SD Card is not communicating properly with the default speed.

    fix-force-sdcard-clk-off-when-idle.patch
    
    Existing Glamo bit for stopping SD Card Clock when there is no
    transfer taking place does not work.  This patch adds stuff around
    the transfer code to force the SD clock up when something is going on
    and down when it is idle.  This'll save a little power and noise ;-)
    
    I tested it briefly and was able to SD Boot normally on Sandisk 512M.
    Wider testing is appreciated.
