  • omapdrm plugin patch automatically tries to load the SGX (omapdrm_pvr) kernel
    module as part of dev_open. The name of SGX kernel module in Android is
    pvrsrvkm.

    This patch removes the auto-load of omapdrm_pvr kernel module to ensure common
    code base across Linux and Android.

  • Previously, delta filtering was applied TSC co-ordinate readouts before
    reporting a single value to user space. This patch replaces delta filtering
    with median filtering. Median filtering sorts co-ordinate readouts, drops
    min and max values, and reports the average of remaining values. This
    method is more sensible than delta filtering. Median filtering is applied
    only if number of readouts is greater than 3 else just average of
    co-ordinate readouts is reported.

  • Based on the latest timing specifications for the TPS65218 from the data
    sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
    from November 2014, we must change the i2c bus speed to better fit within
    the minimum high SCL time required for proper i2c transfer.

    When running at 400khz, measurements show that SCL spends
    0.8125 uS/1.666 uS high/low which violates the requirement for minimum
    high period of SCL provided in datasheet Table 7.6 which is 1 uS.
    Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
    the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.

    Without this patch occasionally a voltage set operation from the kernel
    will appear to have worked but the actual voltage reflected on the PMIC
    will not have updated, causing problems especially with cpufreq that may
    update to a higher OPP without actually raising the voltage on DCDC2,
    leading to a hang.

  • Errata ID: i877

    Description:
    The RGMII Transmit timing is based on the output clock (rgmiin_txc) being
    driven relative to the rising edge of an internal clock and the output
    control/data (rgmiin_txctl/txd) being driven relative to the falling edge
    of an internal clock source. If the internal clock source is allowed to be
    static low (i.e., disabled) for an extended period of time then when the
    clock is actually enabled the timing delta between the rising edge and
    falling edge can change over the lifetime of the device. This can result
    in the device switching characteristics degrading over time, and
    eventually failing to meet the Data Manual Delay Time/Skew specs.
    To maintain RGMII IO Timings, SW should minimize the duration that the
    Ethernet internal clock source is disabled. Note that the device reset
    state for the Ethernet clock is "disabled".

    Workaround:
    If the SoC Ethernet interface(s) are used in RGMII mode, SW should minimize
    the time the Ethernet internal clock source is disabled to a maximum of
    200 hours in a device life cycle. This is done by enabling the clock as
    early as possible in IPL (QNX) or SPL/u-boot (Linux/Android) by setting
    the register CM_GMAC_CLKSTCTRL[1:0]CLKTRCTRL = 0x2:SW_WKUP.
    In addition to programming SW_WKUP(0x2) on CM_GMAC_CLKSTCTRL, SW should
    also program modulemode field as ENABLED(0x2) on CM_GMAC_GMAC_CLKCTRL
    register.

    Note that this erratum applies only when device may need to be used
    for 1Gbit operation.
    Since the POR is to use 1GB mode, enabling this errata by hooking
    ti,no-idle flag to gmac node.

  • According to AM57x TRM, Document SPRUHZ6, Revised October 2014,
    Table 3-1021, SW_SLEEP and HW_AUTO must not be programmed for
    gmac clock domain. And also as per the the Errata i877, gmac clock
    domain should always be kept in SW_WKUP.
    So making the gmac clock domain flag as SWSUP.

  • vpdma_create API is supposed to allocated the struct vpdma_data and
    return it to the driver. Also, it would call the callback function
    when the VPDMA firmware is loaded.

    Typically, VIP VPE drivers have following function call:
    dev->vpdma = vpdma_create(pdev, firmware_load_callback);
    And the callback implementation would continue the probe further.
    Also, the dev->vpdma is accessed from the callback implementation.

    This may lead to race condition between assignment of dev->vpdma
    and the callback function being triggered.
    This would lead to kernel crash because of NULL pointer access.

    Fix this by passing a driver wrapped &vpdma_data instead of allocating
    inside vpdma_create.
    Change the vpdma_create prototype accordingly and fix return paths.

    Also, update the VIP and VPE driver to use the updated API and
    initialize the dev->vpdma before hand so that the race condition
    is avoided.

  • DTO/DCRC errors were not being informed to the mmc core since
    commit ae4bf788ee ("mmc: omap_hsmmc: consolidate error report handling of
    iHSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC
    errors. This is because after this commit 'host->data' is checked after
    it has been cleared to NULL by omap_hsmmc_dma_cleanup().

    Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked
    making core layer not to be aware of DTO/DCRC errors. Because of this
    any command invoked after DTO/DCRC error leads to a hang.

    Fix this by checking for 'host->data' before it is actually cleared.

  • DRM offers no ways to add new displays after the DRM driver has been
    loaded. This causes issues on boards that have multiple displays, and
    omapdrm is loaded when some of them are loaded but not all. The result
    is that omapdrm starts with the displays that were loaded at that time,
    ignoring the displays loaded later.

    This patch changes the behavior so that omapdrm ensures all display are
    loaded which have an alias in the .dts file.

    The downside is that this prevents omapdrm from loading if, say, the
    user has not compiled a kernel module for one of the displays, or
    there's some kind of failure in one of the displays. Thus, after this
    patch, all the displays have to work, or none does.

  • gpmc hwmod on am43xx needs a softreset before idling, so add the
    HWMOD_NEEDS_REIDLE flag so that in the case of no driver being present,
    the module will get properly reidled and shut off after a suspend cycle
    or when attempting to disable it after an RTC+DDR cycle.

  • After the PRCM loses context in the case of an RTC+DDR cycle omap_hwmod
    attempts to return all hwmods to their previous state, however as
    indicated in patch c388763a9c88 ("ARM: OMAP2+: omap_hwmod: Introduce
    HWMOD_NEEDS_REIDLE"), certain hwmods cannot just be disabled when in
    their default state, which is why they need the special handling present
    in that patch when no driver is present.

    In RTC+DDR mode, even if all drivers are present, the modules are all
    returned to their previous state before any driver resume happens so we
    will still face the issue described above. This can be prevented by
    calling _reidle on all hwmods that need it for any module that is being
    disabled to return to it's previous state.

  • Previously when restoring hardreset context during
    omap_hwmod_restore_context we would only deassert the hardreset lines if
    the module was previously active, however, if a hwmod has all hardresets
    asserted then _enable will return without actually enabling the module.

    This is a problem for the gfx hwmod on am437x as it gets disabled in
    suspend path so it appears as disabled to the restore context code but
    then during the attempted enable call during the regular kernel resume
    path, the hwmod cannot actually be enabled.

  • GPMC hwmod is flagged as HWMOD_INIT_NO_IDLE so it is kept
    enabled at boot. If the GPMC driver is not loaded then
    GPMC will not be idled thus preventing CORE from going idle
    during suspend.

    Disable HWMOD_INIT_NO_IDLE and HWMOD_INIT_NO_RESET.

    The only reason HWMOD_INIT_NO_RESET was there was to retain
    GPMC timings/settings configured by bootloader. We no longer
    need that as we're configuring the timins in the kernel.

    There is no reasoning as to why HWMOD_INIT_NO_IDLE was there.
    Seems to have beein blindly copied from omap3/4 hwmod code.

  • As recently understood VIP only expect the input format to be in UYVY form.
    Commit b74d2ff "YUV422 data is not interpreted correctly" was attempting
    to allow all of the various subdevice supported bus format to be used
    as input format to VIP. Unfortunately this is having side effect
    when trying to convert any of these various input formats to NV12
    for example. In order to have VIP generate the correct/expected
    output format for instance UYVY, YUYV or NV12 the input data coming
    from the sub-device must be in UYVY format.

    As a result VIP will now expect the sub-device to support UYVY
    and will be able to support at least:

    - YUV422 UYVY
    - YUV422 YUYV
    - YUV422 VYUY
    - YUV422 YVYU
    - YUV420 NV12

    Also v4l2-compliance was reporting errors and warning wrt
    s/g/try fmt ioctl.
    The errors were caused by mis-handling of invalid format details
    which would generates error return codes.
    These calls are not supposed to fail on invalid input.
    Instead they are supposed to return a valid configuration
    instead of an error as per v4l2-compliance tests.
    Reworked g_fmt, s_fmt and try_fmt to simplify/streamlined them
    Reworked the subdev fmt enumeration on subdev discovery.
    Added subdev g_fmt call on device open to provide a valid initial format.

  • The recent changes to dra7-tpd12s015 driver require mcasp, but it was
    not expressed in the Kconfig, leading to errors like:

    drivers/built-in.o: In function `hdmi_i2c2_hack_demux':
    linux/git/drivers/video/fbdev/omap2/displays-new/dra7-evm-encoder-tpd12s015.c:117:
    undefined reference to `dra7_mcasp_hdmi_gpio_set'

    Add dependency to SND_DAVINCI_SOC_MCASP.
