[ Upstream commit bc83f79bd2119230888fb8574639d5a51b38f903 ]
Generally, declaring a platform device as a static variable is
a bad idea and can cause all kinds of problems, in particular
with the DMA configuration and lifetime rules.
A specific problem we hit here is from a bug in clang that warns
about certain (otherwise valid) macros when used in static variables:
drivers/misc/mic/card/mic_x100.c:285:27: warning: shift count >= width of type [-Wshift-count-overflow]
static u64 mic_dma_mask = DMA_BIT_MASK(64);
^~~~~~~~~~~~~~~~
include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK'
#define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
^ ~~~
A slightly better way here is to create the platform device dynamically
and set the dma mask in the probe function.
This avoids the warning and some other problems, but is still not ideal
because the device creation should really be separated from the driver,
and the fact that the device has no parent means we have to force
the dma mask rather than having it set up from the bus that the device
is actually on.

in force_sig as force_sig is only built to handle synchronous
exceptions.
Further the function force_sig_info changes the signal state if the
signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the
delivery of the signal. The signal SIGKILL can not be ignored and can
not be blocked and SIGNAL_UNKILLABLE won't prevent it from being
delivered.
So using force_sig rather than send_sig for SIGKILL is confusing
and pointless.
Because it won't impact the sending of the signal and and because
using force_sig is wrong, replace force_sig with send_sig.

Clang warns:

uninitialized when used within its own initialization [-Wuninitialized]
void *buf = buf;
~~~ ^~~
1 warning generated.
Arnd's explanation during review:
/*
* Returns the physical address of the partition's reserved page through
* an iterative number of calls.
*
* On first call, 'cookie' and 'len' should be set to 0, and 'addr'
* set to the nasid of the partition whose reserved page's address is
* being sought.
* On subsequent calls, pass the values, that were passed back on the
* previous call.
*
* While the return status equals SALRET_MORE_PASSES, keep calling
* this function after first copying 'len' bytes starting at 'addr'
* into 'buf'. Once the return status equals SALRET_OK, 'addr' will
* be the physical address of the partition's reserved page. If the
* return status equals neither of these, an error as occurred.
*/
static inline s64
sn_partition_reserved_page_pa(u64 buf, u64 *cookie, u64 *addr, u64 *len)
so *len is set to zero on the first call and tells the bios how many
bytes are accessible at 'buf', and it does get updated by the BIOS to
tell us how many bytes it needs, and then we allocate that and try again.

Commit f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status")
added support to save and restore the DMA channel registers when runtime
suspending the ADMA. This change is causing the kernel to crash when
probing the ADMA, if the device is probed deferred when looking up the
channel interrupts. The crash occurs because not all of the channel base
addresses have been setup at this point and in the clean-up path of the
probe, pm_runtime_suspend() is called invoking its callback which
expects all the channel base addresses to be initialised.
Although this could be fixed by simply checking for a NULL address, on
further review of the driver it seems more appropriate that we only call
pm_runtime_get_sync() after all the channel interrupts and base
addresses have been configured. Therefore, fix this crash by moving the
calls to pm_runtime_enable(), pm_runtime_get_sync() and
tegra_adma_init() after the DMA channels have been initialised.

The CPU load values passed to the thermal_power_cpu_get_power
tracepoint are zero for all CPUs, unless, unless the
thermal_power_cpu_limit tracepoint is enabled too:
irq/41-rockchip-98 [000] .... 290.972410: thermal_power_cpu_get_power:
cpus=0000000f freq=1800000 load={{0x0,0x0,0x0,0x0}} dynamic_power=4815
vs
irq/41-rockchip-96 [000] .... 95.773585: thermal_power_cpu_get_power:
cpus=0000000f freq=1800000 load={{0x56,0x64,0x64,0x5e}} dynamic_power=4959

cpus=0000000f freq=408000 cdev_state=10 power=416
There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function. It's this final value which we
want.
Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf(). I ended up doing a little cleanup related to that as
well.

Status of ADMA channel registers is not saved and restored during system
suspend. During active playback if system enters suspend, this results in
wrong state of channel registers during system resume and playback fails
to resume properly. Fix this by saving following channel registers in
runtime suspend and restore during runtime resume.
* ADMA_CH_LOWER_SRC_ADDR
* ADMA_CH_LOWER_TRG_ADDR
* ADMA_CH_FIFO_CTRL
* ADMA_CH_CONFIG
* ADMA_CH_CTRL
* ADMA_CH_CMD
* ADMA_CH_TC
Runtime PM calls will be inovked during system resume path if a playback
or capture needs to be resumed. Hence above changes work fine for system
suspend case.
