commit 5a3e85c3c397 ("pinmux: Use sequential access to access
desc->pinmux data") tried to address the issue when two client of the
same gpio calls pinctrl_select_state() for the same functionality, was
resulting in NULL pointer issue while accessing desc->mux_owner.
However, issue was not completely fixed due to the way it was handled
and it can still result in the same NULL pointer.
The issue occurs due to the following interleaving:
cpu0 (process A) cpu1 (process B)
pin_request() { pin_free() {
mutex_lock()
desc->mux_usecount--; //becomes 0
..
mutex_unlock()
mutex_lock(desc->mux)
desc->mux_usecount++; // becomes 1
desc->mux_owner = owner;
mutex_unlock(desc->mux)
mutex_lock(desc->mux)
desc->mux_owner = NULL;
mutex_unlock(desc->mux)
This sequence leads to a state where the pin appears to be in use
(`mux_usecount == 1`) but has no owner (`mux_owner == NULL`), which can
cause NULL pointer on next pin_request on the same pin.
Ensure that updates to mux_usecount and mux_owner are performed
atomically under the same lock. Only clear mux_owner when mux_usecount
reaches zero and no new owner has been assigned.

Add support for selecting multiple TLMM regions using the
tlmm-test tool.
The current implementation only selects the TLMM Node region
0, which can lead to incorrect region selection.
QCS 615 TLMM Node dts reg:
tlmm: pinctrl@3100000 {
compatible = "qcom,qcs615-tlmm";
reg = <0x0 0x03100000 0x0 0x300000>,
<0x0 0x03500000 0x0 0x300000>,
<0x0 0x03d00000 0x0 0x300000>;
reg-names = "east",
"west",
"south";
QCS615 gpio57 is in the south region with an offset of 0x39000,
and its address is 0x3d39000. However, the default region selection
is region 0 (east region), resulting in a wrong calculated address
of 0x3139000.
Add a tlmm option parameter named tlmm_reg_name to select the region.
If the user does not input the parameter, the default region is 0.

Ensure only valid pins are configured by validating pin mappings before

Rename rzg2l_validate_gpio_pin() to rzg2l_validate_pin() to reflect its
broader purpose validating both GPIO pins and muxed pins. This helps

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().
So use the dev_fwnode() helper.

The local static 'struct pinctrl_desc' is not modified, so can be made
const for code safety.

Assign 'struct pinctrl_desc' .pins and .npins members in definition to
make clear that number of pins is fixed and have less code in the probe.
