soc: qcom: smem_state: Add devm_qcom_smem_state_get()

2021-06-23T18:35:12+00:00

It is easy to forget to call qcom_smem_state_put() after
a qcom_smem_state_get(). Introduce a devm_qcom_smem_state_get()
helper function that automates this so that qcom_smem_state_put()
is automatically called when a device is removed.

soc: qcom: address kernel-doc warnings

2021-03-30T03:49:54+00:00

The command:

  find ./include/linux/soc/qcom/ | xargs ./scripts/kernel-doc -none

reports:

  ./include/linux/soc/qcom/qmi.h:26: warning: cannot understand function prototype: 'struct qmi_header '
  ./include/linux/soc/qcom/qmi.h:101: warning: cannot understand function prototype: 'struct qmi_response_type_v01 '
  ./include/linux/soc/qcom/irq.h:19: warning: expecting prototype for QCOM specific IRQ domain flags that distinguishes the handling of wakeup(). Prototype was for IRQ_DOMAIN_FLAG_QCOM_PDC_WAKEUP() instead
  ./include/linux/soc/qcom/apr.h:126: warning: Function parameter or member '__apr_driver' not described in 'module_apr_driver'
  ./include/linux/soc/qcom/apr.h:126: warning: Excess function parameter '__aprbus_driver' description in 'module_apr_driver'

  ./include/linux/soc/qcom/llcc-qcom.h:86: warning: cannot understand function prototype: 'struct llcc_drv_data '

Address all those warnings by:
  - prefixing kernel-doc descriptions for structs with the keyword 'struct',
  - turning a kernel-doc comment that does not follow the kernel-doc syntax
  into a normal comment, and
  - correcting a parameter name in a kernel-doc comment.

Merge tag 'arm-drivers-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2021-02-21T02:42:28+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "Updates for SoC specific drivers include a few subsystems that have
  their own maintainers but send them through the soc tree:

  SCMI firmware:
   - add support for a completion interrupt

  Reset controllers:
   - new driver for BCM4908
   - new devm_reset_control_get_optional_exclusive_released() function

  Memory controllers:
   - Renesas RZ/G2 support
   - Tegra124 interconnect support
   - Allow more drivers to be loadable modules

  TEE/optee firmware:
   - minor code cleanup

  The other half of this is SoC specific drivers that do not belong into
  any other subsystem, most of them living in drivers/soc:

   - Allwinner/sunxi power management work
   - Allwinner H616 support

   - ASpeed AST2600 system identification support

   - AT91 SAMA7G5 SoC ID driver
   - AT91 SoC driver cleanups

   - Broadcom BCM4908 power management bus support

   - Marvell mbus cleanups

   - Mediatek MT8167 power domain support

   - Qualcomm socinfo driver support for PMIC
   - Qualcomm SoC identification for many more products

   - TI Keystone driver cleanups for PRUSS and elsewhere"

2021-01-09T21:51:36+00:00

Define stub functions for the exposed MDT functions in case
QCOM_MDT_LOADER is not configured.  This allows users of these
functions to link correctly for COMPILE_TEST builds without
QCOM_SCM enabled.

soc: qcom: llcc-qcom: Add support for SM8250 SoC

2020-12-28T18:15:14+00:00

SM8250 SoC uses LLCC IP version 2. In this version, the WRSC_EN register
needs to be written to enable the Write Sub Cache for each SCID. Hence,
use a dedicated "write_scid_en" member with predefined values and write
them for LLCC IP version 2.

regulator: qcom_smd: Add PM660/PM660L regulator support

2020-10-01T20:25:25+00:00

The PM660 and PM660L are a very very common PMIC combo, found on
boards using the SDM630, SDM636, SDM660 (and SDA variants) SoC.

PM660 provides 6 SMPS and 19 LDOs (of which one is unaccesible),
while PM660L provides 5 SMPS (of which S3 and S4 are combined),
10 LDOs and a Buck-or-Boost (BoB) regulator.

The PM660L IC also provides other regulators that are very
specialized (for example, for the display) and will be managed
in the other appropriate drivers (for example, labibb).
