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.Signed-off-by: Haibo Chen

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.Reviewed-by: Peter Chen

The GPC will wake us on peripheral interrupts but not IPIs. So check
them manually by reading the GIC's GICD_SPENDSGIR* registers and
aborting idle if something is pending.We do this only for the last cpu and after taking the required locks.
We know that at this stage the other cpu is in WFI itself or waiting for
the imx_pen_lock and can't trigger any additional IPIs. This means that
the check is not racy.This fixes occasional lost IPIs causing tasks to get stuck in the
TASK_WAKING 'W' state for long periods. This eventually manifested as
rcu stalls.Signed-off-by: Leonard Crestez

This makes the code much easier to reason about. In particular it o
makes sure the imx7d cpuidle driver respects the requirements for
cpu_cluster_pm_enter/exit:* cpu_cluster_pm_enter must be called after cpu_pm_enter has been called
on all cpus in the power domain, and before cpu_pm_exit has been called
on any cpu in the power domain.
* cpu_cluster_pm_exit must be called after cpu_pm_enter has been called

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.Signed-off-by: Cristina Ciocan

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.Reported-by: Leonard Crestez

Using a higher bitclk then expected doesn't always work.
Here is an example:aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav
In this case, the required bitclk is 48000 * 24 * 2 = 2304000
but the closest bitclk that can be derived is 3072000.Now, for format S24_LE, SAI will use slot_width = 24, but since
the clock is faster than expected, it will start to send bytes
from the next channel so the sound will be corrupted.Thus, remove bitclk relaxation condition which was added mostly
for supporting S20_3LE format which was removed from SAI in
