Subject[PATCH v2 0/4] mmc: simplify WP/CD GPIO handling
This series removes convoluted handling of inverted CD and WP lines in
SD/MMC host drivers when using GPIOs.

First patch adds an API: gpiod_toggle_active_low() that switches line
inversion flag in the gpiod structure. Next two patches modify MMC
host's WP and CD initialization to apply all the inversions onto
gpiod's active-low flag. Final patch removes now-unused argument from
init functions.

x86 allyesconfig build-tested.

v2: move argument removal in sdhci-esdhc-imx.c to last patch

Michał Mirosław (4):
gpio: add gpiod_toggle_active_low()
mmc: rework wp-gpio handling
mmc: rework cd-gpio handling
mmc: remove mmc_gpiod_request_*(invert_gpio)
