Add vendor hook to thermal to allow vendor to selectively disable
thermal cooling device stats feature based on requirement. It helps
vendor to optimize memory footprint due to this feature especially
for low memory devices.

perserving the ABI, but that is not needed anymore at this point in

During UFS initialization, devfreq initialization is asynchronous:
ufshcd_async_scan() calls ufshcd_add_lus(), which in turn initializes
devfreq for UFS. The simple ondemand governor is then loaded. If it is
built as a module, request_module() is called and throws a warning:

This occurs because synchronous module loading from async is not
allowed. According to __request_module():
/*
* We don't allow synchronous module loading from async. Module
* init may invoke async_synchronize_full() which will end up
* waiting for this task which already is waiting for the module
* loading to complete, leading to a deadlock.
*/
Such a deadlock was experienced on the Qualcomm QDrive3/sa8540p-ride. With
DEVFREQ_GOV_SIMPLE_ONDEMAND=m, the boot hangs after the warning.
Fix both the warning and the deadlock by moving devfreq initialization out
of the async routine.
Tested on the sa8540p-ride by using fio to put the UFS under load, and
printing the trace generated by
/sys/kernel/tracing/events/ufs/ufshcd_clk_scaling events. The trace looks
similar with and without the change.

The three DMA memory regions allocated for the host memory space are
documented to require alignment of 128, 1024, and 1024 respectively, but
the returned address is checked for PAGE_SIZE alignment.
In the case where these allocations are serviced by e.g. the Arm SMMU, the
size and alignment will be determined by its supported page sizes. In most
cases SZ_4K and a few larger sizes are available.
In the typical configuration this does not cause problems, but in the event
that the system PAGE_SIZE is increased beyond 4k, it's no longer reasonable
to expect that the allocation will be PAGE_SIZE aligned.
Limit the DMA alignment check to the actual alignment requirements written
in the comments in the code, to avoid the UFS core refusing to initialize
with such configuration.

The newly added MSI support is mostly hidden inside of an #ifdef,
except for one line that now causes a build failure when MSI
is disabled:
drivers/ufs/host/ufs-qcom.c: In function 'ufs_qcom_remove':
drivers/ufs/host/ufs-qcom.c:1698:9: error: implicit declaration of function 'platform_msi_domain_free_irqs' [-Werror=i]
1698 | platform_msi_domain_free_irqs(hba->dev);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Above that, the symbol that guards the other call was recently removed, so
that is all dead code at the moment.
Remove the incorrect #ifdef and instead of a Kconfig dependency to only
allow building the driver when CONFIG_GENERIC_MSI_IRQ is enabled. This
symbol is always present when PCI_MSI or ARM_GIC_V3_ITS are enabled, both
of which should be present on kernels that can run on Qualcomm SoCs.
The 'select RESET_CONTROLLER' in combination with this dependency
unfortunately causes a dependency loop and this is a user-visible symbol,
so it's better to change both to 'depends on'.

Move the SCSI execution functions to use a struct for passing in optional
args. This commit adds the new struct, temporarily converts scsi_execute()
and scsi_execute_req() ands a new helper, scsi_execute_cmd(), which takes
the scsi_exec_args struct.
There should be no change in behavior. We no longer allow users to pass in
any request->rq_flags value, but they were only passing in RQF_PM which we
do support by allowing users to pass in the BLK_MQ_REQ flags used by
blk_mq_alloc_request().
Subsequent commits will convert scsi_execute() and scsi_execute_req() users
to the new helpers then remove scsi_execute() and scsi_execute_req().

All UFS host controllers support DMA clustering. Hence enable DMA
clustering.
Notes:
- The max_segment_size parameter implements the 256 KiB limit for the
PRDT. The dma_boundary parameter represents a boundary that must not be
crossed by DMA scatter/gather lists. I'm not aware of any restrictions
on DMA scatter/gather lists in the UFSHCI specification other than the
256 KiB limit for the PRDT and the 32-bit address restriction for
controllers that only support 32-bits DMA. The latter restriction is
already handled by ufshcd_set_dma_mask().
- Without patch "scsi: ufs: exynos: Fix the maximum segment size", this
patch breaks support for the Exynos controller.
The history of the dma_boundary parameter in the UFS driver is as
follows:
* The initial UFS driver did not set the dma_boundary parameter.
* Commit 4dd4130a72 ("scsi: make sure all drivers set the use_clustering
flag") set the .use_clustering flag.
* Commit 4af14d113b ("scsi: remove the use_clustering flag") removed the
use_clustering flag and set the dma_boundary parameter instead.

hence add a vendor specific ops such that SoC vendors can configure their

the legacy (central) interrupt way.
