Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and
etc.) into a single chip. It is designed for industrial control
applications.

+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.

2.7.4
Add driver for Sunplus SP7021 SoC.
Signed-off-by: Wells Lu <[email protected]>
---
Changes in V6
- Addressed comments of Mr. Rob Herring.
- Changed name of vendor property: sunplus,zero_func --> sunplus,zerofunc
- Addedssed comments of Mr. Andy Shevchenko
- Modified Kconfig (bool -> tristate) and Makefile to support 'compile as module'.
- Re-ordered some header files.
- Removed some useless comments.
- Added some inline functions to simplify coding.
- Removed checking existing of property "gpio-controller".
- Removed redundant 'check_mul_overflow()' after a devm_kcalloc() function.
- Added include <linux/types.h> in 'sppctl.h'
- Modified and added some kernel-doc comments.
- Fixed some wrong comment style of multi-line.
- Moved struct sppctl_gpio_chip { ... }; to 'sppctl.c'.
- Others
