  • 11b277eab   ARM: vexpress/TC2: basic PM support ... Browse Code »

    This is the MCPM backend for the Virtual Express A15x2 A7x3 CoreTile
    aka TC2. This provides cluster management for SMP secondary boot and
    CPU hotplug.

  • d41418c0c   ARM: vexpress/dcscb: handle platform coherency exit/setup and CCI ... Browse Code »

    Add the required code to properly handle race free platform coherency exit
    to the DCSCB power down method.

    The power_up_setup callback is used to enable the CCI interface for
    the cluster being brought up. This must be done in assembly before
    the kernel environment is entered.

    Thanks to Achin Gupta and Nicolas Pitre for their help and
    contributions.

  • 1e904e1bf   ARM: vexpress: introduce DCSCB support ... Browse Code »

    This adds basic CPU and cluster reset controls on RTSM for the
    A15x4-A7x4 model configuration using the Dual Cluster System
    Configuration Block (DCSCB).

    The cache coherency interconnect (CCI) is not handled yet.

  • 38669e045   ARM: vexpress: Start using new Versatile Express infrastructure ... Browse Code »

    This patch starts using all the configuration infrastructure.

    - generic GPIO library is forced now

    - sysreg GPIOs are used as MMC CD and WP information sources;
    thanks to this MMCI auxiliary data is not longer necessary

    - DVI muxer and mode control is removed from non-DT V2P-CA9 code
    as this is now handled by the vexpress-dvi driver

    - clock generators control is removed as is being handled by the
    common clock driver now

    - the sysreg and sysctl control is now delegated to the
    appropriate drivers and all related code was removed

    - NOR Flash set_vpp function has been removed as the control
    bit used does _not_ control its VPP line, but the #WP signal
    instead (which is de facto unusable in case of Linux MTD
    drivers); this also allowed the remove its DT auxiliary
    data

    The non-DT code defines only minimal required number of
    the config devices. Device Trees are updated to make use
    of all new features.
