There are some dependencies on the look up table remove functionality in earlier patches, so I think 3/8 can go in only after 1/8. Similarly 5/8 can go only after 2/8. Rest all can be independent.

Similarly 5/8 > can go only after 2/8. Rest all can be independent. Taking patches 'in order' is tough to coordinate and takes a very long time. The best thing to do is have all of the patches taken in via a single tree at the same time. > > Acked-by: Lee Jones <lee.jones@linaro.org> > > > >> diff --git a/drivers/mfd/intel_soc_pmic_core.c b/drivers/mfd/intel_soc_pmic_core.c > >> index f3d918e..a00ddd9 100644 > >> --- a/drivers/mfd/intel_soc_pmic_core.c > >> +++ b/drivers/mfd/intel_soc_pmic_core.c > >> @@ -25,6 +25,7 @@ > >> #include <linux/regmap.h> > >> #include <linux/mfd/intel_soc_pmic.h> > >> #include <linux/gpio/machine.h> > >> +#include <linux/pwm.h> > >> #include "intel_soc_pmic_core.h" > >> > >> /* Lookup table for the Panel Enable/Disable line as GPIO signals */ > >> @@ -37,6 +38,11 @@ static struct gpiod_lookup_table panel_gpio_table = { > >> }, > >> }; > >> > >> +/* PWM consumed by the Intel GFX */ > >> +static struct pwm_lookup crc_pwm_lookup[] = { > >> + PWM_LOOKUP("crystal_cove_pwm", 0, "0000:00:02.0", "pwm_backlight", 0, PWM_POLARITY_NORMAL), > >> +}; > >> + > >> static int intel_soc_pmic_find_gpio_irq(struct device *dev) > >> { > >> struct gpio_desc *desc; > >> @@ -99,6 +105,9 @@ static int intel_soc_pmic_i2c_probe(struct i2c_client *i2c, > >> /* Add lookup table binding for Panel Control to the GPIO Chip */ > >> gpiod_add_lookup_table(&panel_gpio_table); > >> > >> + /* Add lookup table for crc-pwm */ > >> + pwm_add_table(crc_pwm_lookup, ARRAY_SIZE(crc_pwm_lookup)); > >> + > >> ret = mfd_add_devices(dev, -1, config->cell_dev, > >> config->n_cell_devs, NULL, 0, > >> regmap_irq_get_domain(pmic->irq_chip_data)); > >> @@ -121,6 +130,9 @@ static int intel_soc_pmic_i2c_remove(struct i2c_client *i2c) > >> /* Remove lookup table for Panel Control from the GPIO Chip */ > >> gpiod_remove_lookup_table(&panel_gpio_table); > >> > >> + /* remove crc-pwm lookup table */ > >> + pwm_remove_table(crc_pwm_lookup, ARRAY_SIZE(crc_pwm_lookup)); > >> + > >> mfd_remove_devices(&i2c->dev); > >> > >> return 0; > >
