The qcom pinctrl core supports marking functions that represent GPIO mode
via PINCTRL_GPIO_PINFUNCTION(), so that strict pinmuxing does not reject
GPIO requests for pins that are muxed to the GPIO function.
ipq4019 still describes its gpio function with QCA_PIN_FUNCTION(gpio),
so it is not treated as a GPIO pin function. As a result, GPIO consumers
can still conflict with pinctrl states that select the "gpio" function.
Add a QCA_GPIO_PIN_FUNCTION() helper and use it for the ipq4019 gpio
function, matching how the msm-based qcom drivers handle this.
This allows ipq4019 to keep the GPIO-related pin configuration in DTS
without tripping over strict pinmux ownership checks.

[linusw@kernel.org: Dropped intr_target_reg]
Signed-off-by: Linus Walleij <linusw@kernel.org>
On all Qualcomm TLMM generations from APQ8084 onwards, the interrupt
target routing bits are located in the same register as the interrupt
configuration bits (intr_cfg_reg). Only five older SoCs — APQ8064,
IPQ8064, MDM9615, MSM8660 and MSM8960 — have a genuinely separate
interrupt target routing register at a different offset (0x400 + 0x4 * id).
Replace MSM_ACCESSOR(intr_target) with a custom accessor that falls back
to intr_cfg_reg when intr_target_reg is zero. Apply the same fallback in
the SCM path. Drop the now-redundant .intr_target_reg initializer from
all SoC drivers where it duplicated intr_cfg_reg, keeping it only in
the five drivers where it genuinely differs.

The intr_target_bit for Eliza was incorrectly set to 5, which is the
value used by older Qualcomm SoCs (e.g. SM8250, MSM8996, X1E80100).
Newer SoCs such as SM8650, SM8750, Milos, and Kaanapali all use
bit 8 for the interrupt target field in the TLMM interrupt configuration
register.
Eliza belongs to the newer generation and should use bit 8 to correctly
route interrupts to the KPSS (Applications Processor). Using the wrong
bit position means the interrupt target routing is silently misconfigured,
which can result in GPIO interrupts not being delivered to the expected
processor.
Fix this by aligning Eliza with the correct value used by its peer SoCs.

GPIO controller driver should typically implement the .get_direction()
callback as GPIOLIB internals may try to use it to determine the state
of a pin. Since introduction of shared proxy, it prints a warning splat
when using a shared spmi gpio.
The implementation is not easy because the controller supports enabling
the input and output logic at the same time, so we aligns on the
behaviour of the .get() operation and return -EINVAL in other
situations.

Qualcomm SC7280 and SM8350 SoCs have slightly different LPASS audio
blocks (v9.4.5 and v9.2), however the LPASS LPI pin controllers are
exactly the same. The driver for SM8350 has two issues, which can be
fixed by simply moving over to SC7280 driver which has them correct:
1. "i2s2_data_groups" listed twice GPIO12, but should have both GPIO12
and GPIO13,
2. "swr_tx_data_groups" contained GPIO5 for "swr_tx_data2" function, but
that function is also available on GPIO14, thus listing it twice is
not necessary. OTOH, GPIO5 has also "swr_rx_data1", so selecting
swr_rx_data function should not block the TX one.

Replace disable_irq() with disable_irq_nosync() in msm_pinmux_set_mux()
to prevent deadlock when wakeup IRQ is triggered on the same
GPIO being reconfigured.
The issue occurs when a wakeup IRQ is triggered on a GPIO and the IRQ
handler attempts to reconfigure the same GPIO's pinmux. In this scenario,
msm_pinmux_set_mux() calls disable_irq() which waits for the currently
running IRQ handler to complete, creating a circular dependency that
results in deadlock.
Using disable_irq_nosync() avoids waiting for the IRQ handler to
complete, preventing the deadlock condition while still properly
disabling the interrupt during pinmux reconfiguration.
