* gpio: Free gpio.inc from oppressive orderCraig Hesling2020-02-251-10/+131
| | | | | | | | | | | | | | | | | | | | | | | | | This CL enables gpio.wrap to correct the order of all declaration in gpio.inc. Previously, gpio.inc had to be written such that GPIO_INTs were at the top of the file, GPIOs following GPIO_INTs, and then IOEX_INTs before IOEXs declaration. This ordering was required because the signal name enums were used to index into the interrupt handler table. See crrev.com/c/263973 (gpio: Refactor IRQ handler pointer out of gpio_list). This constraint not only limited the creativity and art of an individual crafting a gpio.inc, but also made recursively including gpio.inc's (for baseboard or other) messy and ugly.

* IO_Expander: introduce the common interface of IO expanderCHLin2019-07-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the common code to provide a friendly interface to control the IOs of IO expander. It adopts a similar concept to GPIO. 1. Define the IO expander IO in gpio.inc by the format: IOEX(name, EXPIN(ioex, port, offset), flags) - name: the name of this IO pin - EXPIN(ioex, port, offset) - ioex: the IO expander port (defined in board.c) this IO pin belongs to. - port: the port number in the IO expander chip. - offset: the bit offset in the port above. - flags: the same as the flags of GPIO. 2. The following APIs are supported: 1. ioex_get_flags_by_mask 2. ioex_set_flags_by_mask 3. ioex_get_flags 4. ioex_set_flags 5. ioex_get_level 6. ioex_set_level 7. ioex_init 3. The following console commands are supported: 1. ioexget [IO_EXPANDER_PIN_NAME] 2. ioexset IO_EXPANDER_PIN_NAME 0/1 BRANCH=none BUG=none TEST=No error for "make buildall" TEST=Apply this and related CLs, manually test each API, make sure each function works correctly with IO expander chip (NCT3807/NCT3808.)

* gpio: Refactor IRQ handler pointer out of gpio_listAseda Aboagye2015-04-101-7/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the gpio_info struct, we had a irq_handler pointer defined even though a majority of the GPIOs did not have irq handlers associated. By removing the irq_handler pointer out of the struct, we can save some space with some targets saving more than others. (For example, ~260 bytes for samus_pd). This change also brings about a new define: GPIO_INT(name, port, pin, flags, signal) And the existing GPIO macro has had the signal parameter removed since they were just NULL. GPIO(name, port, pin, flags) In each of the gpio.inc files, all the GPIOs with irq handlers must be defined at the top of the file. This is because their enum values from gpio_signal are used as the index to the gpio_irq_handlers table. BUG=chromium:471331 BRANCH=none TEST=Flashed ec to samus and samus_pd, verified lightbar tap, lid, power button, keyboard, charging, all still working.

* gpio: Replace duplication in gpio declarations with X-macro fileAnton Staaf2014-06-261-0/+47
Previously each board.h and board.c contained an enum and an array for gpio definitons that had to be manually kept in sync, with no compiler assistance other than that their lengths matched. This change adds a single gpio.inc file that declares all gpio's that a board uses and is used as an X-macro include file to generate both the gpio_signal enum and the gpio_list array.
