  • In order to make sure that get the regulator correctly.
    Check the return value of devm_regulator_get().
    Return value directly if it is '-EPROBE_DEFER'

  • g2d code has different parameter setting about stride parameter.
    For compatibility with all cases of using PxP, we need add this
    improved feature.

  • If pxp use crop x/y valuse as the upper left coordinate in
    out buffer, pxp driver only need to write out buffer base
    address to pxp out_buf register. If pxp driver use zero as
    ps_ulc register value, pxp out_buf register need an offset
    added with out buffer base address.

  • set WFE (WFE_A on imx7d, and WFE_B on imx6ull/imx6sll) input address to
    framebuffer start address, and set left/top coordinate since the framebuffer is
    the original source of WFE (i.e., not from PXP output) when bypass legacy mode.
    The patch also limits the condition to bypass legacy mode when not use
    EPDC_FLAG_USE_ALT_BUFFER.

  • when gpu memory is from virtual system pool, the physical address
    will become invalid, driver should enable mmu mapping accordingly.

    but current kernel driver return the zero address with default value,
    this mistake will cause gpu write into the wrong memory from zero.

    this fix mark the invalid address for the virtual memory.

  • For HannStar (HSD100PXN1 Rev: 1-A00C11 F/W:0634) LVDS touch screen,
    it has a special request for the EETI touch controller. The host
    needs to trigger I2C event to device FW at booting first, and then
    the FW can switch to I2C interface. Otherwise, the FW can’t work
    with I2C interface, and can't generate any interrupt when touch
    the screen.

    This patch send an I2C command before the device wake up, make sure
    the device switch to I2C interface first.

  • After the chipidea driver introduce extcon for id and vbus, it's able
    to wakeup from another irq source, in case the system with extcon ID
    cable, wakeup from usb ID cable and device removal, the usb device
    disconnect irq may come firstly before the extcon notifier while system
    resume, so we will get 2 "wakeup" irq, one for usb device disconnect;
    and one for extcon ID cable change(real wakeup event), current driver
    treat them as 2 successive wakeup irq so can't handle it correctly, then
    finially the usb irq can't be enabled. This patch adds a check to bypass
    further usb events before controller resume finished to fix it.

    due to the commit e188cbf7564fba80e8339b9406e8740f3e495c63
    "gpio: mxc: shift gpio_mxc_init() to subsys_initcall level", and
    gpio_reset uses arch_initcall level, the gpio driver is not yet
    ready when call device_reset() thus return -EPROBE_DEFER. But the caller
    of device_reset(), mipi_dsi_enable() has no defer strategy.
    use of_reset_control_get() function in init() function, which will be called
    in probe function in mxsfb driver, to workaround the defer case.

  • CAAM aes modes share descriptors, because of this CAAM requires an IV
    for ECB. ECB does not need an IV and users do not have to pass valid
    IV vectors. To allow correct usage with minimum impact to the driver a
    zero IV is provided by the driver for ECB operations that need it.

  • This patch fixes build warning that 2 variables may be used uninitialized
    in the pxp_fetch_config() function in drivers/dma/pxp/pxp_dma_v3.c .

    The variables in_fmt and out_fmt are passed as parameters to
    pxp_fetch_shift_calc() only if shift_bypass is false. This flag cannot be
    false unless changed in a code block that also assigns in_fmt and out_fmt.

    Since the compiler cannot detect this flow, it shows a warning that in_fmt
    and out_fmt are not initialized. Fix this by changing the code flow such
    that in_fmt and out_fmt are sent as parameters in the same code block where
    they are assigned.

  • It is possible for an irq triggered by channel0 to be received later,
    after clks are disabled. If that happens then clearing them by writing
    to SDMA_H_INTR won't work and the system will hang processing infinite
    interrupts. Actually, don't need interrupt triggered on channel0 since
    it's pollling to know channel0 done rather than interrupt in current
    code, just clear BD setting to disable channel0 interrupt to avoid the
    above case.

  • The DCP driver does not obey cryptlen, when doing CTS this results in
    passing to hardware input stream lengths which are not multiple of
    block size. This causes the hw to misbehave. Also not honoring
    cryptlen makes CTS fail. A check was introduced to prevent future
    erroneous stream lengths from reaching the hardware. Code which is
    splitting the input stream in internal DCP pages was changed to obey
    cryptlen.

  • On imx6sl and imx6ull DCP writes at least 32 bytes in the output
    buffer instead of hash length as documented. Add intermediate buffer
    to prevent write out of bounds.

    When requested to produce null hashes DCP fails to produce valid
    output. Add software workaround to bypass hardware and return valid output.

  • The clock driver may enable uart clock tree when earlycon/earlyprintk
    kernel param is enabled, and the clock gate specify CLK_SET_RATE_GATE,
    then .of_clk_set_defaults() set the dts node assigned-rate will be failed.
    So set parent and set rate in clock driver is reasonable.

    epdc can display picture normally.

    So fill it in this patch.
