-/**
|
|
|
|
- * struct sx150x_platform_data - config data for SX150x driver
|
|
|
|
- * @gpio_base: The index number of the first GPIO assigned to this
|
|
|
|
- * GPIO expander. The expander will create a block of
|
|
|
|
- * consecutively numbered gpios beginning at the given base,
|
|
|
|
- * with the size of the block depending on the model of the
|
|
|
|
- * expander chip.
|
|
|
|
- * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
|
|
|
|
- * instead of as an oscillator, increasing the size of the
|
|
|
|
- * GP(I)O pool created by this expander by one. The
|
|
|
|
- * output-only GPO pin will be added at the end of the block.
|
|
|
|
- * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
|
|
|
|
- * for each IO line in the expander. Setting the bit at
|
|
|
|
- * position n will enable the pull-up for the IO at
|
|
|
|
- * the corresponding offset. For chips with fewer than
|
|
|
|
- * 16 IO pins, high-end bits are ignored.
|
|
|
|
- * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
|
|
|
|
- * resistor for each IO line in the expander. Setting the
|
|
|
|
- * bit at position n will enable the pull-down for the IO at
|
|
|
|
- * the corresponding offset. For chips with fewer than
|
|
|
|
- * 16 IO pins, high-end bits are ignored.
|
|
|
|
- * @io_open_drain_ena: A bit-mask which enables-or disables open-drain
|
|
|
|
- * operation for each IO line in the expander. Setting the
|
|
|
|
- * bit at position n enables open-drain operation for
|
|
|
|
- * the IO at the corresponding offset. Clearing the bit
|
|
|
|
- * enables regular push-pull operation for that IO.
|
|
|
|
- * For chips with fewer than 16 IO pins, high-end bits
|
|
|
|
- * are ignored.
|
|
|
|
- * @io_polarity: A bit-mask which enables polarity inversion for each IO line
|
|
|
|
- * in the expander. Setting the bit at position n inverts
|
|
|
|
- * the polarity of that IO line, while clearing it results
|
|
|
|
- * in normal polarity. For chips with fewer than 16 IO pins,
|
|
|
|
- * high-end bits are ignored.
|
|
|
|
- * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
|
|
|
|
- * is connected, via which it reports interrupt events
|
|
|
|
- * across all GPIO lines. This must be a real,
|
|
|
|
- * pre-existing IRQ line.
|
|
|
|
- * Setting this value < 0 disables the irq_chip functionality
|
|
|
|
- * of the driver.
|
|
|
|
- * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
|
|
|
|
- * IRQ lines will appear. Similarly to gpio_base, the expander
|
|
|
|
- * will create a block of irqs beginning at this number.
|
|
|
|
- * This value is ignored if irq_summary is < 0.
|
|
|
|
- * @reset_during_probe: If set to true, the driver will trigger a full
|
|
|
|
- * reset of the chip at the beginning of the probe
|
|
|
|
- * in order to place it in a known state.
