drivers: meson: secure-pwrc: always enable DMA domain

2023-07-19T14:36:07+00:00

[ Upstream commit 0bb4644d583789c97e74d3e3047189f0c59c4742 ]

Starting from commit e45f243409db ("firmware: meson_sm:
populate platform devices from sm device tree data") pwrc
is probed successfully and disables unused pwr domains.
By A1 SoC family design, any TEE requires DMA pwr domain
always enabled.

soc: mediatek: SVS: Fix MT8192 GPU node name

2023-07-19T14:35:59+00:00

[ Upstream commit 95094495401bdf6a0649d220dfd095e6079b5e39 ]

Device tree node names should be generic. The planned device node name
for the GPU, according to the bindings and posted DT changes, is "gpu",
not "mali".

Fix the GPU node name in the SVS driver to follow.

soc/fsl/qe: fix usb.c build errors

2023-07-19T14:35:54+00:00

[ Upstream commit 7b1a78babd0d2cd27aa07255dee0c2d7ac0f31e3 ]

Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
being set. When USB_FSL_QE is set, QE_USB deafults to y, which
causes build errors when QUICC_ENGINE is not set. Making
QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.

Fixes these build errors:

driver: soc: xilinx: use _safe loop iterator to avoid a use after free

2023-07-19T14:35:42+00:00

[ Upstream commit c58da0ba3e5c86e51e2c1557afaf6f71e00c4533 ]

The hash_for_each_possible() loop dereferences "eve_data" to get the
next item on the list.  However the loop frees eve_data so it leads to
a use after free.  Use hash_for_each_possible_safe() instead.

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

[ 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.

Merge tag 'arm-fixes-6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2023-06-10T20:01:09+00:00

Pull ARM SoC fixes from Arnd Bergmann:
 "Most of the changes this time are for the Qualcomm Snapdragon
  platforms.

  There are bug fixes for error handling in Qualcomm icc-bwmon,
  rpmh-rsc, ramp_controller and rmtfs driver as well as the AMD tee
  firmware driver and a missing initialization in the Arm ff-a firmware
  driver. The Qualcomm RPMh and EDAC drivers need some rework to work
  correctly on all supported chips.

  The DT fixes include:

   - i.MX8 fixes for gpio, pinmux and clock settings

   - ADS touchscreen gpio polarity settings in several machines

   - Address dtb warnings for caches, panel and input-enable properties
     on Qualcomm platforms

   - Incorrect data on qualcomm platforms fir SA8155P power domains,
     SM8550 LLCC, SC7180-lite SDRAM frequencies and SM8550 soundwire

   - Remoteproc firmware paths are corrected for Sony Xperia 10 IV"

soc: fsl: cpm1: Fix TSA and QMC dependencies in case of COMPILE_TEST

2023-05-30T11:25:25+00:00

In order to compile tsa.c and qmc.c, CONFIG_CPM must be set.

Without this dependency, the linker fails with some missing
symbols for COMPILE_TEST configurations that need QMC without
enabling CPM.

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

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.
