soc: qcom: make QCOM_PDR_MSG selectable

2026-08-18T09:41:56+00:00

Selecting QCOM_PDR_HELPERS from outside of a CONFIG_QCOM_SOC
block causes a build warning:

WARNING: unmet direct dependencies detected for QCOM_PDR_MSG
  Depends on [n]: QCOM_SOC [=n]
  Selected by [y]:
  - QCOM_PDR_HELPERS [=y] && NET [=y]

Avoid this by allowing QCOM_PDR_MSG to be selected as well.

soc: qcom: ubwc: Fix link error when QCOM_SMEM=n

ubwc_config.c calls qcom_smem_is_available() and qcom_smem_dram_get_hbb()
unconditionally, so QCOM_UBWC_CONFIG=y with QCOM_SMEM=n fails to link:

  arm-linux-gnueabihf-ld: ubwc_config.c:(.text+0x2c): undefined
      reference to 'qcom_smem_is_available'

Add the missing 'depends on QCOM_SMEM'.

soc: qcom: Avoid SCM and SPM for cpuidle drivers

2026-07-11T15:01:51+00:00

QCOM_SCM and QCOM_SPM are user-selectable drivers, thus
ARM_QCOM_SPM_CPUIDLE should rather avoid selecting them but instead
depend to avoid any possible unmet dependencies.

ARM_QCOM_SPM_CPUIDLE does use symbols from SCM and SPM, and since it
cannot be built-in, the dependency must be as built-in.

soc: qcom: Make important drivers default

2026-07-11T15:01:50+00:00

The drivers for Qualcomm SoC components are covering a basic or
fundamental SoC blocks.  Usually they are required for booting or to
achieve basic expected functionality when running Linux.  These drivers
do not represent any sort of buses visible to the board
designers/configurators, thus they should be always enabled, regardless
how SoC is used in the final board.

Kernel configuration should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.

Switch most of the Qualcomm SoC drivers to a default 'yes' or
'module' for ARCH_QCOM, to match existing defconfig usage.

This has no impact on arm64 defconfig, arm qcom_defconfig and arm
multi_v7_defconfig.

multi:
+#define CONFIG_QCOM_PDR_HELPERS_MODULE 1
+#define CONFIG_QCOM_PBS_MODULE 1
+#define CONFIG_QCOM_AOSS_QMP 1
+#define CONFIG_QCOM_APR_MODULE 1
+#define CONFIG_QCOM_LLCC_MODULE 1

qcom:
+#define CONFIG_QCOM_PDR_HELPERS_MODULE 1
+#define CONFIG_QCOM_PBS_MODULE 1
+#define CONFIG_QCOM_AOSS_QMP 1
+#define CONFIG_QCOM_APR_MODULE 1
+#define CONFIG_QCOM_SPM 1
+#define CONFIG_QCOM_LLCC_MODULE 1

The change will however enable by default all drivers for arm or arm64
COMPILE_TEST builds, whenever ARCH_QCOM is selected, which feels
logical: if one selects ARCH_QCOM then probably by default wants to
build test it entirely.  Kernels with COMPILE_TEST are not supposed to
be used for booting.

soc: qcom: Restrict drivers per ARM/ARM64

2026-07-11T15:01:50+00:00

There is no point to allow selecting core SoC drivers for Qualcomm ARMv7
SoCs when building ARM64 kernel, and vice versa.

This makes kernel configuration more difficult as many do not remember
the Qualcomm SoCs model names/numbers and their properties like
architecture.  No features should be lost because:
1. There won't be a single image for ARMv7 and ARMv8/9 SoCs.
2. Newer ARMv8/9 SoCs won't be running in arm32 emulation mode.

soc: qcom: Hide all drivers behind selectable menu

2026-07-11T15:01:50+00:00

Switch from a simple menu to menuconfig, so all Qualcomm SoC drivers
will be under one selectable option, allowing to disable them all which
should make kernel configuration easier when preparing a non-Qualcomm
kernel.

This has few benefits (functional impact of this commit):

1. Allow compile testing of QCOM_OCMEM, which previously required
   ARCH_QCOM.

2. Hide behind ARCH_QCOM or COMPILE_TEST drivers specific to Qualcomm
   which should not be available to other kernel builds:
   QCOM_PMIC_PDCHARGER_ULOG, QCOM_PMIC_GLINK, QCOM_SPM and QCOM_PBS.

Various names for Qualcomm as a company are used in user-visible config
options: QCOM, Qualcomm and Qualcomm Technologies.  Switch to unified
"Qualcomm" so it will be easier for users to identify the options when
for example running menuconfig.
