3914dc8803 Bluetooth: coredump: Introduce and apply hci_devcd_state_name()
Introduce hci_devcd_state_name() to describe the devcoredump state by a
string name instead of a plain number, for several reasons:

1) Applying it in coredump.c makes the devcoredump state in log messages
   more readable than a plain number.
2) Transport drivers may need to show the devcoredump state name too.
3) In future, the universal state name could be notified to userspace
   via uevent, allowing a universal application (e.g. a daemon) to be
   developed to save the coredump, which is otherwise discarded by the
   device coredump core after 5 minutes (DEVCD_TIMEOUT); see
   nxp_coredump_notify().

Also drop a trailing space from two bt_dev_dbg() format strings while
applying it in coredump.c.

6ec1896b53 Bluetooth: fix BT dependency for submodules
The modules rfcomm (BT_RFCOMM), bnep (BT_BNEP), hidp (BT_HIDP), and
bluetooth_6lowpan (BT_6LOWPAN) are dependent on the bluetooth module
(BT, tristate) only transitively through the boolean BT_BREDR for the
first three and through the boolean BT_LE for the bluetooth_6lowpan.
Therefore, the modules can be selected as built-in even if the BT=m.
The combination of BT=m and =y for the said modules leads to the kernel
build system silently ignoring those modules, without ever compiling
them as built-in or as loadable modules.

Add BT as a direct dependency to the Kconfig of rfcomm, bnep, hidp, and
bluetooth_6lowpan. The modules set to =y when BT=m will default to =m,
rather then getting silently ignored by the build system.

290a364460 Bluetooth: btrsi: Move set_bt_context after successful HCI registration
In rsi_hci_attach(), ops->set_bt_context() stores the newly allocated
h_adapter into common->bt_adapter before hci_alloc_dev() and
hci_register_dev() are called. If either of these fails, h_adapter
is freed but common->bt_adapter remains a non-NULL dangling pointer.

This causes a deterministically reachable use-after-free when the
device operates in a BT+WiFi coexistence mode and CONFIG_RSI_COEX
is enabled. The following software-only trigger paths exist:

  1. SDIO driver .remove  (rsi_disconnect)
  2. USB  driver .disconnect (rsi_disconnect)
  3. SDIO driver .shutdown (rsi_shutdown)
  4. Hibernation .freeze  (rsi_freeze)

All four paths check:
    if (IS_ENABLED(CONFIG_RSI_COEX) && coex_mode > 1 && bt_adapter)
        rsi_bt_ops.detach(bt_adapter);  // use-after-free

coex_mode is set during rsi_91x_init(), before rsi_hci_attach() is
called, and is not cleared on attach failure. Since set_bt_context()
already wrote bt_adapter before the failure, the deinit paths see a
non-NULL dangling pointer and proceed to detach it.

Fix this by moving set_bt_context() after hci_register_dev() succeeds.
On failure paths bt_adapter stays NULL, and the deinit callers correctly
skip the detach call.

0fdb6ca821 Bluetooth: hci_ldisc: reject invalid tty write lengths
The HCI UART write worker assumes that a tty write callback returns a
value in the range from zero through the skb length. A negative value or
a value larger than the skb length is passed to accounting and skb_pull,
which can corrupt skb state.

20b9962806 pinctrl: airoha: fix IRQ mask/unmask code
When using IRQCHIP_IMMUTABLE, airoha_irq_unmask() must manually call
gpiochip_enable_irq() and airoha_irq_mask() must call
gpiochip_disable_irq(). Without these calls, gpiolib never sets the
GPIOD_FLAG_IRQ_IS_ENABLED bit. Because this bit is missing,
gpiod_direction_output() will not realize the pin is actively used
as an interrupt.

b8dd305548 pinctrl: airoha: fix getting gpiochip/pinctrl pointers in the IRQ handling code
airoha_irq_unmask(), airoha_irq_mask(), airoha_irq_type() functions
impements brain damaged logic to retrieve gpiochip and pinctrl pointers.

Details:

    gpiochip = irq_data_get_irq_chip_data(data);

will initialize gpiochip variable with data->chip_data value. This value
initialized inside gpiochip_irq_map() function

    static int gpiochip_irq_map(struct irq_domain *d, unsigned int irq,
			        irq_hw_number_t hwirq)
    {
	struct gpio_chip *gc = d->host_data;
        ...
	irq_set_chip_data(irq, gc);
	...
    }

Thus gpiochip variable of 'struct airoha_pinctrl_gpiochip *' type will be
initialized with a pointer to a variable of 'struct gpio_chip' type.

Luckily, gpio_chip is the first element of airoha_pinctrl_gpiochip, so
gpiochip pointer will get a correct value.

This patch implements correct logic of getting gpiochip and pinctrl
pointers.

239fd71600 pinctrl: airoha: fix AN7583 MDIO pin mux config
an7583_mdio_pins[] pointed at pins 43/44 (I2C1_SDA/I2C1_SCL) instead of
pins 53/54 (MDC_0/MDIO_0 respectively GPIO 51/52). Also the MDIO function
group wrote GPIO_SGMII_MDIO_MODE_MASK (bit 13 of REG_GPIO_PON_MODE, an
unrelated SGMII MDIO mode) and GPIO_MDC_IO_MASTER_MODE_MODE (BIT(14),
an EN7581 specific bit from REG_GPIO_2ND_I2C_MODE).

Fix both by setting an7583_mdio_pins[] to { 53, 54 } and rewriting the
function group to clear AN7583_MDC_0_GPIO_MODE_MASK (bit 25) and
AN7583_MDIO_0_GPIO_MODE_MASK (bit 26) of REG_GPIO_PON_MODE. Both bits
are cleared by the hwinit at probe.

739bc85aed pinctrl: airoha: an7581: fix mux/conf of pcie_reset pins
In the an7581 case
 * gpio47 and pcie_reset0 shares pin 60,
 * gpio48 and pcie_reset1 shares pin 61,
 * gpio49 and pcie_reset2 shares pin 62.
but current driver treat them as pins 61--63. This is wrong.

Also current an7581 pinmux implementation have following issues:
 * current pcie_reset pin function actually sets corresponding
   pins as gpios.
 * there is no proper way to set pcie_reset pins as gpios.
 * there is no way to set pcie_reset pins as pwm.

This patch fixes above issues.

WARNING:
There is a contradiction in the Airoha documentation. AN7581 programming
guide claims:
 - gpio44 and pcie_reset0 shares the same pin
 - gpio45 and pcie_reset1 shares the same pin
 - gpio46 and pcie_reset2 shares the same pin
While AN7581 datasheet claims:
 - gpio47 and pcie_reset0 shares the same pin
 - gpio48 and pcie_reset1 shares the same pin
 - gpio49 and pcie_reset2 shares the same pin
The datasheet should be considered as a more reliable source.
