8 title: Sunplus SP7021 Pin Controller

15 The Sunplus SP7021 pin controller is used to control SoC pins. Please
16 refer to pinctrl-bindings.txt in this directory for details of the common
19 SP7021 has 99 digital GPIO pins which are numbered from GPIO 0 to 98. All
20 are multiplexed with some special function pins. SP7021 has 3 types of
23 (1) function-group pins:
24 Ex 1 (SPI-NOR flash):
25 If control-field SPI_FLASH_SEL is set to 1, GPIO 83, 84, 86 and 87
26 will be pins of SPI-NOR flash. If it is set to 2, GPIO 76, 78, 79
27 and 81 will be pins of SPI-NOR flash.
30 If control-bit UA0_SEL is set to 1, GPIO 88 and 89 will be TX and
34 If control-bit EMMC_SEL is set to 1, GPIO 72, 73, 74, 75, 76, 77,
37 Properties "function" and "groups" are used to select function-group
40 (2) fully pin-mux (like phone exchange mux) pins:
41 GPIO 8 to 71 are 'fully pin-mux' pins. Any pins of peripherals of
42 SP7021 (ex: UART_1, UART_2, UART_3, UART_4, I2C_0, I2C_1, and etc.)
43 can be routed to any pins of fully pin-mux pins.
46 If control-field UA1_TX_SEL is set to 3, TX pin of UART_1 will be
47 routed to GPIO 10 (3 - 1 + 8 = 10).
48 If control-field UA1_RX_SEL is set to 4, RX pin of UART_1 will be
49 routed to GPIO 11 (4 - 1 + 8 = 11).
50 If control-field UA1_RTS_SEL is set to 5, RTS pin of UART_1 will
51 be routed to GPIO 12 (5 - 1 + 8 = 12).
52 If control-field UA1_CTS_SEL is set to 6, CTS pin of UART_1 will
53 be routed to GPIO 13 (6 - 1 + 8 = 13).
56 If control-field I2C0_CLK_SEL is set to 20, CLK pin of I2C_0 will
57 be routed to GPIO 27 (20 - 1 + 8 = 27).
58 If control-field I2C0_DATA_SEL is set to 21, DATA pin of I2C_0
59 will be routed to GPIO 28 (21 - 1 + 9 = 28).
61 Totally, SP7021 has 120 peripheral pins. The peripheral pins can be
62 routed to any of 64 'fully pin-mux' pins.
65 SP7021 has a built-in I/O processor.
68 Vendor property "sunplus,pins" is used to select "fully pin-mux" pins,
