ARM: dts: am335x-pocketbeagle: add gpio-line-names The BeagleBoard.org PocketBeagle has P1 and P2 headers [0] which expose many of the TI AM3358 SoC balls to stacking expansion boards called "capes", or to other external connections like jumper wires connected to a breadboard. Note: the AM3358 die is actually embedded inside of the OSD335x-SM System-in-Package (SiP) [1] but that is irrelevant to the gpio driver. Many of the P1 and P2 header pins can muxed to a GPIO line. The gpio-line-names describe which P1 or P2 pin that line goes to and the default mux for that P1 or P2 pin if it is not GPIO. Some GPIO lines are named "[NC]" as the corresponding balls are not routed to anything on the PCB. The goal for these names is to make it easier for a user viewing the output of gpioinfo to determine which P1 or P2 pin is connected to a GPIO line. The output of gpioinfo on a PocketBeagle would be: gpiochip0 - 32 lines: line 0: "[NC]" unused input active-high line 1: "[NC]" unused input active-high line 2: "P1.08 [SPI0_CLK]" unused input active-high line 3: "P1.10 [SPI0_MISO]" unused input active-high line 4: "P1.12 [SPI0_MOSI]" unused input active-high line 5: "P1.06 [SPI0_CS]" unused input active-high line 6: "[MMC0_CD]" "cd" input active-low [used] line 7: "P2.29 [SPI1_CLK]" unused input active-high line 8: "[SYSBOOT]" unused input active-high line 9: "[SYSBOOT]" unused input active-high line 10: "[SYSBOOT]" unused input active-high line 11: "[SYSBOOT]" unused input active-high line 12: "P1.26 [I2C2_SDA]" unused input active-high line 13: "P1.28 [I2C2_SCL]" unused input active-high line 14: "P2.11 [I2C1_SDA]" unused input active-high line 15: "P2.09 [I2C1_SCL]" unused input active-high line 16: "[NC]" unused input active-high line 17: "[NC]" unused input active-high line 18: "[NC]" unused input active-high line 19: "P2.31 [SPI1_CS]" unused input active-high line 20: "P1.20 [PRU0.16]" unused input active-high line 21: "[NC]" unused input active-high line 22: "[NC]" unused input active-high line 23: "P2.03" unused input active-high line 24: "[NC]" unused input active-high line 25: "[NC]" unused input active-high line 26: "P1.34" unused input active-high line 27: "P2.19" unused input active-high line 28: "[NC]" unused input active-high line 29: "[NC]" unused input active-high line 30: "P2.05 [UART4_RX]" unused input active-high line 31: "P2.07 [UART4_TX]" unused input active-high gpiochip1 -

ARM: dts: am335x-pocketbeagle: set default mux for gpio pins These pins on the PocketBeagle P1 and P2 headers are connected to AM3358 balls with gpio lines, and these pins are not used for any other peripherals by default. These GPIO lines are unclaimed and could be used by userspace program through the gpiod ABI. This patch adds a "default" state in the am33xx_pinmux node and sets the mux for those pins to gpio (mode 7) and input enable. The "pinctrl-single,bias-pullup" and "pinctrl-single,bias-pulldown" pinconf properties are also set for each pin per the ball reset state in section 4.2 of the datasheet [0]. This is the AM335x pin control register format in Table 9-60 [1]: bit attribute value ---------------------------------- 31-7 reserved 0 on reset 6 slew { 0: fast, 1: slow } 5 rx_active { 0: rx disable, 1: rx enabled } 4 pu_typesel { 0: pulldown select, 1: pullup select } 3 puden { 0: pud enable, 1: disabled } 2 mode 3 bits to selec mode 0 to 7 1 mode 0 mode The values for the bias pinconf properties are derived as follows: pinctrl-single,bias-pullup = <[input] [enabled] [disable] [mask]>; pinctrl-single,bias-pullup = < 0x10 0x10 0x10 0x18 >; 2^5 2^4 2^3 2^2 2^1 2^0 | 0x20 0x10 0x08 0x04 0x02 0x01 | --------------------------------------------------| input x 1 0 x x x | 0x10 enabled x 1 0 x x x | 0x10 disabled x 0 0 x x x | 0x00 mask x 1 1 x x x | 0x18 pinctrl-single,bias-pulldown = <[input] [enabled] [disable] [mask]>; pinctrl-single,bias-pulldown = < 0x0 0x0 0x10 0x18 >; 2^5 2^4 2^3 2^2 2^1 2^0 | 0x20 0x10 0x08 0x04 0x02 0x01 | --------------------------------------------------| input x 0 0 x x x | 0x00 enabled x 0 0 x x x | 0x00 disabled x 1 0 x x x | 0x10 mask x 1 1 x x x | 0x18 [0] http://www.ti.com/lit/ds/symlink/am3358.pdf [1] https://www.ti.com/lit/ug/spruh73q/spruh73q.pdf Signed-off-by: Drew Fustini <drew@beagleboard.org> Signed-off-by: Tony Lindgren <tony@atomide.com>
