fc6c7cd387 irqchip/ti-sci-intr: Fix freeing of irqs
ti_sci_intr_irq_domain_free() assumes that out_irq of intr is stored in
data->chip_data and uses it for calling ti_sci irq_free() and then
mark the out_irq as available resource. But ti_sci_intr_irq_domain_alloc()
is storing p_hwirq(parent's hardware irq) which is translated from out_irq.
This is causing resource leakage and eventually out_irq resources might
be exhausted. Fix ti_sci_intr_irq_domain_alloc() by storing the out_irq
in data->chip_data.

ea6c25e605 irqchip/ti-sci: Simplify with dev_err_probe()
Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and the error value gets printed.

There is also no need to assign NULL to 'intr->sci' as it is part of
devm-allocated memory.

8ddf1905a9 irqchip/ti-sci-intr: Fix unsigned comparison to zero
ti_sci_intr_xlate_irq() return -ENOENT on fail, p_hwirq
should be int type.

a5b659bd4b irqchip/ti-sci-intr: Add support for INTR being a parent to INTR
Driver assumes that Interrupt parent to Interrupt router is always GIC.
This is not true always and an Interrupt Router can be a parent to
Interrupt Router. Update the driver to detect the parent and request the
parent irqs accordingly.

a6df49f422 firmware: ti_sci: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

cd844b0715 irqchip/ti-sci-intr: Add support for Interrupt Router driver
Texas Instruments' K3 generation SoCs has an IP Interrupt Router
that does allows for redirection of input interrupts to host
interrupt controller. Interrupt Router inputs are either from a
peripheral or from an Interrupt Aggregator which is another
interrupt controller.

Configuration of the interrupt router registers can only be done by
a system co-processor and the driver needs to send a message to this
co processor over TISCI protocol.

Add support for Interrupt Router driver over TISCI protocol.
