  • 273032f78   OMAP4: Enable 800 MHz and 1 GHz MPU-OPP ... Browse Code »

    Almost all OMAP4 boards support OPP 800 MHz and OPP 1 GHz.
    Enable them in OPP Table. For small minority of boards which use
    OMAP4430-800 MHz device OPP 1GHz is not supported,
    OPP 1GHz should be disabled from board file.

  • 15f13e23e   OMAP3+: OPP: Replace voltage values with Macros ... Browse Code »

    Since all voltage data is now centralized in oppxxx_data.c, we can replace
    the values in the opp table with the macros used for voltage values.

    This will avoid opp table and voltage layer having conflicting values.

  • c0718df4d   OMAP2+: voltage: reorganize, split code from data ... Browse Code »

    This is a first pass at reorganizing mach-omap2/voltage.c:

    - Separate almost all of the data from the code of mach-omap2/voltage.c.
    The code remains in mach-omap2/voltage.c. The data goes into one
    of several places, depending on what type of data it is:

    - Silicon process/validation data: mach-omap2/opp*_data.c
    - VC (Voltage Controller) data: mach-omap2/vc*_data.c
    - VP (Voltage Processor) data: mach-omap2/vp*_data.c
    - Voltage domain data: mach-omap2/voltagedomains*_data.c

    The ultimate goal is for all this data to be autogenerated, the same
    way we autogenerate the rest of our data.

    - Separate VC and VP common data from VDD-specific VC and VP data.

    - Separate common voltage.c code from SoC-specific code; reuse common code.

    - Reorganize structures to avoid unnecessary memory loss due to unpacked
    fields.

    There is much left to be done. VC code and VP code should be separated out
    into vc*.c and vp*.c files. Many fields in the existing structures are
    superfluous, and should be removed. Some code in voltage.c seems to be
    duplicated; that code should be moved into functions of its own. Proper
    voltage domain code should be created, as was done with the powerdomain
    and clockdomains, and powerdomains should reference voltagedomains.

    Thanks to Shweta Gulati for comments. Thanks
    to Rajendra Nayak for finding and fixing some bugs
    that prevented OMAP4 from booting:

    https://patchwork.kernel.org/patch/587311/

    His patch has been folded into this one to avoid breaking OMAP4
    between patches. Thanks also to Kevin Hilman for
    finding and fixing a compile problem when !CONFIG_PM:

    http://www.spinics.net/lists/arm-kernel/msg118067.html

    His patch has also been folded into this one to avoid breaking
    !CONFIG_PM builds.

  • eb05ead90   OMAP3|4: OPP: make omapx_opp_init non-static ... Browse Code »

    omap3 and omap4 opp_init should be made non-static to allow
    for platform specific opp table tweaking. making these static
    conflicts with the definition in pm.h(global) as well.
    we include pm.h as well to ensure that there are no such prototype
    conflicts with actual implementation in the future.

  • f5a6422d4   omap4: opp: add OPP table data ... Browse Code »

    This patch adds OPP tables for OMAP4. New file has been added to keep
    the OMAP4 opp tables and the registration of these tables with the
    generic opp framework by OMAP SoC OPP interface.

    Based on:
    http://dev.omapzoom.org/?p=santosh/kernel-omap4-base.git;a=blob;f=arch/arm/mach-omap2/opp44xx_data.c;h=252e3d0cb6050a64f390b9311c1c4977d74f762a;hb=refs/heads/omap4_next
