soc: qcom: mdt_loader: Fix unconditional call to scm_pas_mem_setup

2023-07-23T11:53:57+00:00

commit bcb889891371c3cf767f2b9e8768cfe2fdd3810f upstream.

Commit ebeb20a9cd3f ("soc: qcom: mdt_loader: Always invoke PAS
mem_setup") dropped the relocate check and made pas_mem_setup run
unconditionally. The code was later moved with commit f4e526ff7e38
("soc: qcom: mdt_loader: Extract PAS operations") to
qcom_mdt_pas_init() effectively losing track of what was actually
done.

The assumption that PAS mem_setup can be done anytime was effectively
wrong, with no good reason and this caused regression on some SoC
that use remoteproc to bringup ath11k. One example is IPQ8074 SoC that
effectively broke resulting in remoteproc silently die and ath11k not
working.

On this SoC FW relocate is not enabled and PAS mem_setup was correctly
skipped in previous kernel version resulting in correct bringup and
function of remoteproc and ath11k.

To fix the regression, reintroduce the relocate check in
qcom_mdt_pas_init() and correctly skip PAS mem_setup where relocate is
not enabled.

soc: qcom: geni-se: Add interfaces geni_se_tx_init_dma() and geni_se_rx_init_dma()

2023-07-19T14:35:27+00:00

[ Upstream commit 6d6e57594957ee9131bc3802dfc8657ca6f78fee ]

The geni_se_xx_dma_prep() interfaces necessarily do DMA mapping before
initiating DMA transfers. This is not suitable for spi where framework
is expected to handle map/unmap.

Expose new interfaces geni_se_xx_init_dma() which do only DMA transfer.

soc: qcom: Rename ice to qcom_ice to avoid module name conflict

2023-05-25T03:30:52+00:00

The following error was reported when building x86_64 allmodconfig:

error: the following would cause module name conflict:
  drivers/soc/qcom/ice.ko
  drivers/net/ethernet/intel/ice/ice.ko

Seems the 'ice' module name is already used by some Intel ethernet
driver, so lets rename the Qualcomm Inline Crypto Engine (ICE) module
from 'ice' to 'qcom_ice' to avoid any kind of errors/confusions.

Merge tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2023-04-27T18:53:57+00:00

Pull driver core updates from Greg KH:
 "Here is the large set of driver core changes for 6.4-rc1.

  Once again, a busy development cycle, with lots of changes happening
  in the driver core in the quest to be able to move "struct bus" and
  "struct class" into read-only memory, a task now complete with these
  changes.

  This will make the future rust interactions with the driver core more
  "provably correct" as well as providing more obvious lifetime rules
  for all busses and classes in the kernel.

  The changes required for this did touch many individual classes and
  busses as many callbacks were changed to take const * parameters
  instead. All of these changes have been submitted to the various
  subsystem maintainers, giving them plenty of time to review, and most
  of them actually did so.

  Other than those changes, included in here are a small set of other
  things:

   - kobject logging improvements

   - cacheinfo improvements and updates

   - obligatory fw_devlink updates and fixes

   - documentation updates

   - device property cleanups and const * changes

   - firwmare loader dependency fixes.

  All of these have been in linux-next for a while with no reported
  problems"
