If the following call chain fails
adf_device_post_nocopy() ->
adf_buffer_map() ->
dma_buf_attach(); dma_buf_map_attachment()
then the attachment returned by dma_buf_attach() will get cleaned up
twice: first during the error-handling path inside adf_buffer_map(), and
again during the error-handling path inside adf_device_post_nocopy().
Fix this by zeroing out the mapping data inside adf_buffer_map()'s
error-handling path. When adf_device_post_nocopy() hands it back to
adf_buffer_mapping_cleanup(), it will deliberately skip over zeroed-out
data.
(The second adf_buffer_mapping_cleanup() call inside
adf_device_post_nocopy() is not a bug; it's intended to clean up after
any *other* buffers we handled as part of this request.)

Add support to indicate if the switcher is acting in input limited state.
Switcher running in high duty cycle (HDC) mode should also be indicated as
input limited condition.
HDC is a 5uS pulse and sw reading the real time status register may not
indicate that it is active. Basically the presence of the pulses and the
interrupts indicate HDC and conversely their absence indicates no
HDC. Set a flag in the interrupt and clear it in a delayed work queue in
20mS. As long as the interrupts happen this flag will remain set,
indicating HDC.

Make sure to only call regulator_disable() on VCONN only if
it was previously enabled, else it could result in an
unbalanced disable state. Subsequent enables would then be
no-ops and the regulator would not actually turn on.

commit 8bb5ef79bc0f4016ecf79e8dce6096a3c63603e4 upstream.
There are three subsystem callbacks in css shutdown path -
css_offline(), css_released() and css_free(). Except for
css_released(), cgroup core didn't guarantee the order of invocation.
css_offline() or css_free() could be called on a parent css before its
children. This behavior is unexpected and led to bugs in cpu and
memory controller.
The previous patch updated ordering for css_offline() which fixes the
cpu controller issue. While there currently isn't a known bug caused
by misordering of css_free() invocations, let's fix it too for
consistency.
css_free() ordering can be trivially fixed by moving putting of the
parent css below css_free() invocation.

There are instances of QMI message timeout and because of this
stability issues are seen way after the QMI message failure. To
aid the debugging, enhance the debug capabilities by adding
ASSERT in case of failure.
Also update the logs properly to indicate which message really

Because of a change in the underlying bus driver, the secure touch
layer in the input drivers is now required to control directly the
clocks which are needed during the touch sessions. The clocks which
are associated with the underlying I2C bus are clk_gcc_blsp1_ahb_clk
and clk_gcc_blsp1_qup3_i2c_apps_clk. These clocks are turned on/off
when the secure touch session is started/ended.
