soc: qcom: smem_state: Add refcounting for the 'state->of_node'

2022-10-21T10:38:31+00:00

[ Upstream commit 90681f53b9381c23ff7762a3b13826d620c272de ]

In qcom_smem_state_register() and qcom_smem_state_release(), we
should better use of_node_get() and of_node_put() for the reference
creation and destruction of 'device_node'.

soc: qcom: smsm: Fix refcount leak bugs in qcom_smsm_probe()

2022-10-21T10:38:31+00:00

[ Upstream commit af8f6f39b8afd772fda4f8e61823ef8c021bf382 ]

There are two refcount leak bugs in qcom_smsm_probe():

(1) The 'local_node' is escaped out from for_each_child_of_node() as
the break of iteration, we should call of_node_put() for it in error
path or when it is not used anymore.
(2) The 'node' is escaped out from for_each_available_child_of_node()
as the 'goto', we should call of_node_put() for it in goto target.

 "There are three independent sets of changes:

     of the MMIO accessors, which is intended to help understand
     problems with device drivers and has been part of Qualcomm's vendor
     kernels for many years

   - A patch from Sebastian Siewior to rework the handling of IRQ stacks
     in softirqs across architectures, which is needed for enabling
     PREEMPT_RT

   - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of
     the code behind that, after the last users of this old interface
     made it in through the netdev, scsi, media and staging trees"

Pull ARM SoC drivers from Arnd Bergmann:
 "The SoC driver updates contain changes to improve support for
  additional SoC variants, as well as cleanups an minor bugfixes
  in a number of existing drivers.

  Notable updates this time include:

   - Support for Qualcomm MSM8909 (Snapdragon 210) in various drivers

   - Updates for interconnect drivers on Qualcomm Snapdragon

   - A new driver support for NMI interrupts on Fujitsu A64fx

   - A rework of Broadcom BCMBCA Kconfig dependencies

   - Improved support for BCM2711 (Raspberry Pi 4) power management to
     allow the use of the V3D GPU

   - Cleanups to the NXP guts driver

   - Arm SCMI firmware driver updates to add tracing support, and use
     the firmware interfaces for system power control and for power
     capping"

soc: qcom: spm: Add CPU data for MSM8909

2022-07-18T23:05:07+00:00

Given the lack of public documentation for the SPM, the configuration
data is taken without modification from Qualcomm's msm-3.10 release [1].
It is pretty much identical to the one for MSM8916, except that 0x3B is
missing in the sequence for standalone power collapse for some reason.

QCOM_RPMPD requires PM_GENERIC_DOMAINS/_OF, which in turns requires
CONFIG_PM. I forgot about the latter in my earlier patch (it's still
in -next as of the time of committing, hence no Fixes: tag). Fix it.
