1d79dca631 Merge tag 'omap-for-v5.13/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers
Driver changes for omaps for genpd support for v5.13

In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to patch the related drivers to prepare.

These are mostly ti-sysc interconnect target module driver changes and soc
init changes. However, there are minor changes to other drivers too. There
are changes for pci-dra7xx probe, omap-prm idle configuration, and a omap5
clock change:

- ti-sysc needs iorange check improved when the interconnect target module
  has no control registers listed

- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
  issues with missing resources and unnecessary deferred probe

- ti-sysc debug option can now detect more devices

- ti-sysc now warns if an old incomplete devicetree data is found as we
  now rely on it being complete for am3 and 4

- soc init code needs to check for prcm and prm nodes for omap4/5 and
  dra7

- omap-prm driver needs to enable autoidle retention support for omap4

- omap5 clocks are missing gpmc and ocmc clock registers

- pci-dra7xx now needs to use builtin_platform_driver instead of using
  builtin_platform_driver_probe for deferred probe to work

There are also few minor non-urgent fixes:

- soc init code pdata_quirks_init_clocks should be static

- ti-sysc has few unneeded semiconon typos

- ti-sysc can use kzalloc instead of kcalloc for a single element

c650b8dc7a tee: optee: do not check memref size on return from Secure World
When Secure World returns, it may have changed the size attribute of the
memory references passed as [in/out] parameters. The GlobalPlatform TEE
Internal Core API specification does not restrict the values that this
size can take. In particular, Secure World may increase the value to be
larger than the size of the input buffer to indicate that it needs more.

Therefore, the size check in optee_from_msg_param() is incorrect and
needs to be removed. This fixes a number of failed test cases in the
GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09
when OP-TEE is compiled without dynamic shared memory support
(CFG_CORE_DYN_SHM=n).

c45e66a6b9 soc/tegra: pmc: Fix completion of power-gate toggling
The SW-initiated power gate toggling is dropped by PMC if there is
contention with a HW-initiated toggling, i.e. when one of CPU cores is
gated by cpuidle driver. Software should retry the toggling after 10
microseconds on Tegra20/30 SoCs, hence add the retrying. On Tegra114+ the
toggling method was changed in hardware, the TOGGLE_START bit indicates
whether PMC is busy or could accept the command to toggle, hence handle
that bit properly.

The problem pops up after enabling dynamic power gating of 3D hardware,
where 3D power domain fails to turn on/off "randomly".

The programming sequence and quirks are documented in TRMs, but PMC
driver obliviously re-used the Tegra20 logic for Tegra30+, which strikes
back now. The 10 microseconds and other timeouts aren't documented in TRM,
they are taken from downstream kernel.

54443ef6f5 clk: tegra: Add PLLE HW power sequencer control
PLLE has a hardware power sequencer logic which is a state machine
that can power on/off PLLE without any software intervention. The
sequencer has two inputs, one from XUSB UPHY PLL and the other from
SATA UPHY PLL. PLLE provides reference clock to XUSB and SATA UPHY
PLLs. When both of the downstream PLLs are powered-off, PLLE hardware
power sequencer will automatically power off PLLE for power saving.

XUSB and SATA UPHY PLLs also have their own hardware power sequencer
logic. XUSB UPHY PLL is shared between XUSB SuperSpeed ports and PCIE
controllers. The XUSB UPHY PLL hardware power sequencer has inputs
from XUSB and PCIE. When all of the XUSB SuperSpeed ports and PCIE
controllers are in low power state, XUSB UPHY PLL hardware power
sequencer automatically power off PLL and flags idle to PLLE hardware
power sequencer. Similar applies to SATA UPHY PLL.

PLLE hardware power sequencer has to be enabled after both downstream
sequencers are enabled.

This commit adds two helper functions:
1. tegra210_plle_hw_sequence_start() for XUSB PADCTL driver to enable
   PLLE hardware sequencer at proper time.

2. tegra210_plle_hw_sequence_is_enabled() for XUSB PADCTL driver to
   check whether PLLE hardware sequencer has been enabled or not.

1e7c57355a firmware: raspberrypi: Keep count of all consumers
When unbinding the firmware device we need to make sure it has no
consumers left. Otherwise we'd leave them with a firmware handle
pointing at freed memory.

Keep a reference count of all consumers and introduce rpi_firmware_put()
which will permit automatically decrease the reference count upon
unbinding consumer drivers.

e259c2926c PCI: pci-dra7xx: Prepare for deferred probe with module_platform_driver
After updating pci-dra7xx driver to probe with ti-sysc and genpd, I
noticed that dra7xx_pcie_probe() would not run if a power-domains property
was configured for the interconnect target module.

Turns out that module_platform_driver_probe uses platform_driver_probe(),
while builtin_platform_driver uses platform_driver_register().

Only platform_driver_register() works for deferred probe as noted in the
comments for __platform_driver_probe() in drivers/base/platform.c with a
line saying "Note that this is incompatible with deferred probing".

With module_platform_driver_probe, we have platform_driver_probe() produce
-ENODEV error at device_initcall() level, and no further attempts are done.
Let's fix this by using module_platform_driver instead.

Note this is not an issue currently as we probe devices with simple-bus,
and only is needed as we start probing the device with ti-sysc, or when
probed with simple-pm-bus.

Note that we must now also remove __init for probe related functions to
avoid a section mismatch warning.

bc0b964da3 soc: ti: omap-prm: Allow hardware supported retention when idle
When moving the l4 interconnect instances to probe with simple-pm-bus and
genpd, we will have l4per and core domains stop idling unless we configure
the domain bits to allow retention when idle.

As the TI SoCs have hardware autoidle capabilities, this is safe to do.
The domains will only enter retention on WFI when none of the devices on
the domain block autoidle in the hardware. This follows what we are
already currently doing.
