Add those control as a new GPIO in a lookup table for gpio-crystalcove chip during CRC driver load v2: Make the lookup table static (Thierry) Remove the lookup table during driver remove (Thierry) v3: Correct the subject line (Lee jones) CC: Samuel Ortiz Cc: Linus Walleij Cc: Alexandre Courbot Cc: Thierry Reding Acked-by: Lee Jones Acked-by: Linus Walleij Signed-off-by: Shobhit Kumar --- drivers/mfd/intel_soc_pmic_core.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/drivers/mfd/intel_soc_pmic_core.c b/drivers/mfd/intel_soc_pmic_core.c index 7b50b6b..f3d918e 100644 --- a/drivers/mfd/intel_soc_pmic_core.c +++ b/drivers/mfd/intel_soc_pmic_core.c @@ -24,8 +24,19 @@ #include #include #include +#include #include "intel_soc_pmic_core.h" +/* Lookup table for the Panel Enable/Disable line as GPIO signals */ +static struct gpiod_lookup_table panel_gpio_table = { + /* Intel GFX is consumer */ + .dev_id = "0000:00:02.0", + .table = { + /* Panel EN/DISABLE */ + GPIO_LOOKUP("gpio_crystalcove", 94, "panel", GPIO_ACTIVE_HIGH), + }, +}; + static int intel_soc_pmic_find_gpio_irq(struct device *dev) { struct gpio_desc *desc; @@ -85,6 +96,9 @@ static int intel_soc_pmic_i2c_probe(struct i2c_client *i2c, if (ret) dev_warn(dev, "Can't enable IRQ as wake source: %d\n", ret); + /* Add lookup table binding for Panel Control to the GPIO Chip */ + gpiod_add_lookup_table(&panel_gpio_table); + ret = mfd_add_devices(dev, -1, config->cell_dev, config->n_cell_devs, NULL, 0, regmap_irq_get_domain(pmic->irq_chip_data)); @@ -104,6 +118,9 @@ static int intel_soc_pmic_i2c_remove(struct i2c_client *i2c) regmap_del_irq_chip(pmic->irq, pmic->irq_chip_data); + /* Remove lookup table for Panel Control from the GPIO Chip */ + gpiod_remove_lookup_table(&panel_gpio_table); + mfd_remove_devices(&i2c->dev); return 0; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in Please read the FAQ at http://www.tux.org/lkml/
