      soc: ti: wkup_m3_ipc: Fix race condition with rproc_boot · 03729cfa
      Dave Gerlach authored 
      Any user of wkup_m3_ipc calls wkup_m3_ipc_get to get a handle and this
checks the value of the static variable m3_ipc_state to see if the
wkup_m3 is ready. Currently this is populated during probe before
rproc_boot has been called, meaning there is a window of time that
wkup_m3_ipc_get can return a valid handle but the wkup_m3 itself is not
ready, leading to invalid IPC calls to the wkup_m3 and system
instability.

To avoid this, move the population of the m3_ipc_state variable until
after rproc_boot has succeeded to guarantee a valid and usable handle
is always returned.

      ARM: dts: beagle-x15-common: Model 5V0 regulator · e17e7c49
      Kishon Vijay Abraham I authored 
      On am57xx-beagle-x15, 5V0 is connected to P16, P17, P18 and P19
connectors. On am57xx-evm, 5V0 regulator is used to get 3V6 regulator
which is connected to the COMQ port. Model 5V0 regulator here in order
for it to be used in am57xx-evm to model 3V6 regulator.

      ARM: dts: am571x-idk: Fix gpios property to have the correct gpio number · 0c4eb2a6
      Kishon Vijay Abraham I authored 
      commit d23f3839 ("ARM: dts: DRA7: Add pcie1 dt node for
EP mode") while adding the dt node for EP mode for DRA7 platform,
added rc node for am571x-idk and populated gpios property with
"gpio3 23". However the GPIO_PCIE_SWRST line is actually connected
to "gpio5 18". Fix it here. (The patch adding "gpio3 23" was tested
with another am57x board in EP mode which doesn't rely on reset from
host).

      Kishon Vijay Abraham I authored 
      PERST# line in the PCIE connector is driven by the host mode and not
EP mode. The gpios property here is used for driving the PERST# line.
Remove gpios property from all endpoint device tree nodes.

      ARM: dts: sun8i: a83t: Correct USB3503 GPIOs polarity · 1c226017
      Marek Szyprowski authored 
      Current USB3503 driver ignores GPIO polarity and always operates as if the
GPIO lines were flagged as ACTIVE_HIGH. Fix the polarity for the existing
USB3503 chip applications to match the chip specification and common
convention for naming the pins. The only pin, which has to be ACTIVE_LOW
is the reset pin. The remaining are ACTIVE_HIGH. This change allows later
to fix the USB3503 driver to properly use generic GPIO bindings and read
polarity from DT.

      Linus Torvalds authored 
      Pull ARM SoC fixes from Olof Johansson:
 "I didn't get a batch in this weekend, so here's what we queued up last
  week and today.

   - A couple of defconfigs add back debugfs -- it used to be implicitly
     enabled through CONFIG_TRACING, but 0e4a459f ("tracing:
     Remove unnecessary DEBUG_FS dependency") removed that.

   - The rest are mostly minor fixlets of the usual kind; some DT
     tweaks, a headerfile refactor that needs a build fix now, etc"

      bus: ti-sysc: Fix iterating over clocks · 2c81f0f6
      Tony Lindgren authored 
      Commit d878970f ("bus: ti-sysc: Add separate functions for handling
clocks") separated handling of optional clocks from the main clocks, but
introduced an issue where we do not necessarily allocate a slot for both
fck and ick clocks, but still assume fixed slots for enumerating over the
clocks.

Let's fix the issue by ensuring we always have slots for both fck and ick
even if we don't use ick, and don't attempt to enumerate optional clocks
if not allocated.

In the long run we might want to simplify things a bit by only allocating
space only for the optional clocks as we have only few devices with
optional clocks.

Fixes: d878970f ("bus: ti-sysc: Add separate functions for handling clocks")
