ARM: omap1: fix build with no SoC selected

2022-04-22T09:08:55+00:00

In a multiplatform randconfig kernel, one can have
CONFIG_ARCH_OMAP1 enabled, but none of the specific SoCs.
This leads to some build issues as the code is not
meant to deal with this configuration at the moment:

arch/arm/mach-omap1/io.c:86:20: error: unused function 'omap1_map_common_io' [-Werror,-Wunused-function]
arch/arm/mach-omap1/pm.h:113:2: error: "Power management for this processor not implemented yet" [-Werror,-W#warnings]

Use the same trick as on OMAP2 and guard the actual compilation
of platform code with another Makefile ifdef check based
on an option that depends on having at least one SoC enabled.

The io.c file still needs to get compiled to allow building
device drivers with a dependency on CONFIG_ARCH_OMAP1.

ARM: omap1: move some headers to include/linux/soc

2022-04-21T13:01:02+00:00

There are three remaining header files that are used by omap1
specific device drivers:

- mach/soc.h provides cpu_is_omapXXX abstractions
- mach/hardware.h provides omap_read/omap_write functions
  and physical addresses
- mach/mux.h provides an omap specific pinctrl abstraction

This is generally not how we do platform abstractions today,
and it would be good to completely get rid of these in favor
of passing information through platform devices and the pinctrl
subsystem.

However, given that nobody is working on that, just move it
one step forward by splitting out the header files that are
used by drivers today from the machine headers that are only
used internally.

ARM: omap1: move mach/usb.h to include/linux/soc

2022-04-21T13:00:59+00:00

The register definitions in this header are used in at least four
different places, with little hope of completely cleaning that up.

Split up the file into a portion that becomes a linux-wide header
under include/linux/soc/ti/, and the parts that are actually only
needed by board files.

mailbox: ti-msgmgr: Operate mailbox in polled mode during system suspend

2022-03-13T01:33:30+00:00

During the system suspend path we must set all queues to operate in
polled mode as it is possible for any protocol built using this mailbox,
such as TISCI, to require communication during the no irq phase of suspend,
and we cannot rely on interrupts there.

Polled mode is implemented by allowing the mailbox user to define an
RX channel as part of the message that is sent which is what gets polled
for a response. If polled mode is enabled, this will immediately be
polled for a response at the end of the mailbox send_data op before
returning success for the data send or timing out if no response is
received.

Finally, to ensure polled mode is always enabled during system suspend,
iterate through all queues to set RX queues to polled mode during system
suspend and disable polled mode for all in the resume handler.

soc: ti: ti_sci_inta_msi: Remove ti_sci_inta_msi_domain_free_irqs()

2021-12-16T21:22:19+00:00

The function has no users and is pointless now that the core frees the MSI
descriptors, which means potential users can just use msi_domain_free_irqs().
