Merge tag 'pinctrl-v5.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "No core changes this time. Just new driver code and improvements!

  New drivers:

   - New driver for the Broadcom BCM4908 SoC.

   - New subdriver for Tesla FSD (Full Self Driving) SoC, a derivative
     of the Samsung Exynos pin control driver.

   - New driver for the Amlogic Meson S4 SoC.

   - New driver for the Sunplus SP7021 SoC.

   - New driver for the Microsemi Ocelot family ServalT SoC.

   - New subdriver for Intel Alder Lake-M SoC.

   - New subdriver for Intel Ice Lake-N SoC, including PCH support.

   - New subdriver for Renesas R8A779F0 SoC.

   - New subdriver for Mediatek MT8186 SoC.

   - New subdriver for NXP Freescale i.MX93 SoC.

   - New driver for Nuvoton WPCM450 SoC.

   - New driver for Qualcomm SC8280XP SoC.

  Improvements:

   - Wakeup support on Samsung Exynos850 and ExynosAutov9.

   - Serious and voluminous maintenance cleanup and refactoring in the
     Renesas drivers. Mainly sharing similar data between the different
     SoC subdrivers.

   - Qualcomm SM8450 EGPIO support.

   - Drive strength support on the Mediatek MT8195.

   - Add some missing groups and functions to the Ralink RT2880"

+              The specific driving setup is controlled by E1E0EN.
+              When E1=0/E0=0, the strength is 0.125mA.
+              When E1=0/E0=1, the strength is 0.25mA.
+              When E1=1/E0=0, the strength is 0.5mA.
+              When E1=1/E0=1, the strength is 1mA.
+              EN is used to enable or disable the specific driving setup.
+              Valid arguments are described as below:
+              0: (E1, E0, EN) = (0, 0, 0)
+              1: (E1, E0, EN) = (0, 0, 1)

+
+description: |
+  The Sunplus SP7021 pin controller is used to control SoC pins. Please
+  refer to pinctrl-bindings.txt in this directory for details of the common
+  pinctrl bindings used by client devices.
+
+  SP7021 has 99 digital GPIO pins which are numbered from GPIO 0 to 98. All
+  are multiplexed with some special function pins. SP7021 has 3 types of
+  special function pins:
+
+  (1) function-group pins:
+      Ex 1 (SPI-NOR flash):
+        If control-field SPI_FLASH_SEL is set to 1, GPIO 83, 84, 86 and 87
+        will be pins of SPI-NOR flash. If it is set to 2, GPIO 76, 78, 79
+        and 81 will be pins of SPI-NOR flash.
+
+      Ex 2 (UART_0):
+        If control-bit UA0_SEL is set to 1, GPIO 88 and 89 will be TX and
+        RX pins of UART_0 (UART channel 0).
+
+      Ex 3 (eMMC):
+        If control-bit EMMC_SEL is set to 1, GPIO 72, 73, 74, 75, 76, 77,
+        78, 79, 80, 81 will be pins of an eMMC device.
+
+      Properties "function" and "groups" are used to select function-group
+      pins.
+
+  (2) fully pin-mux (like phone exchange mux) pins:
+      GPIO 8 to 71 are 'fully pin-mux' pins. Any pins of peripherals of
+      SP7021 (ex: UART_1, UART_2, UART_3, UART_4, I2C_0, I2C_1, and etc.)
+      can be routed to any pins of fully pin-mux pins.
+
+      Ex 1 (UART channel 1):
+        If control-field UA1_TX_SEL is set to 3, TX pin of UART_1 will be
+        routed to GPIO 10 (3 - 1 + 8 = 10).
+        If control-field UA1_RX_SEL is set to 4, RX pin of UART_1 will be
+        routed to GPIO 11 (4 - 1 + 8 = 11).
+        If control-field UA1_RTS_SEL is set to 5, RTS pin of UART_1 will
+        be routed to GPIO 12 (5 - 1 + 8 = 12).
+        If control-field UA1_CTS_SEL is set to 6, CTS pin of UART_1 will
+        be routed to GPIO 13 (6 - 1 + 8 = 13).
+
+      Ex 2 (I2C channel 0):
+        If control-field I2C0_CLK_SEL is set to 20, CLK pin of I2C_0 will
+        be routed to GPIO 27 (20 - 1 + 8 = 27).
+        If control-field I2C0_DATA_SEL is set to 21, DATA pin of I2C_0
+        will be routed to GPIO 28 (21 - 1 + 9 = 28).
+
+      Totally, SP7021 has 120 peripheral pins. The peripheral pins can be
+      routed to any of 64 'fully pin-mux' pins.
+
+  (3) I/O processor pins
+      SP7021 has a built-in I/O processor.
+      Any GPIO pins (GPIO 0 to 98) can be set to pins of I/O processor.
+
+  Vendor property "sunplus,pins" is used to select "fully pin-mux" pins,
+  "I/O processor pins" and "digital GPIO" pins.
+
+  The device node of pin controller of Sunplus SP7021 has following
+  properties.

+
+          It consists of one or more integers which represents the config
+          setting for corresponding pin. Each integer defines a individual
+          pin in which:
+
+          Bit 32~24: defines GPIO number. Its range is 0 ~ 98.
+          Bit 23~16: defines types: (1) fully pin-mux pins
+                                    (2) IO processor pins
+                                    (3) digital GPIO pins
+          Bit 15~8:  defines pins of peripherals (which are defined in
+                     'include/dt-binging/pinctrl/sppctl.h').
+          Bit 7~0:   defines types or initial-state of digital GPIO pins.
+
+          Please use macro SPPCTL_IOPAD to define the integers for pins.
