	  This selects Hardware reset support aka pwrseq-emmc for eMMC
	  devices. By default this option is set to y.

	  This driver can also be built as a module. If so, the module
	  will be called pwrseq_emmc.

	  This selects simple hardware reset support aka pwrseq-simple for MMC

	  will be called pwrseq_simple.
mmc: support unsafe resume of cards Since many have the system root on MMC/SD we must allow some foot shooting when it comes to resume. We cannot detect if a card is removed and reinserted during suspend, so the safe approach would be to assume it was, avoiding potential filesystem corruption. This will of course not work if you cannot release the card before suspend. This commit adds a compile time option that makes the MMC layer assume the card wasn't touched if it is redetected upon resume.

mmc: pwrseq: convert to proper platform device simple-pwrseq and emmc-pwrseq drivers rely on platform_device structure from of_find_device_by_node(), this works mostly. But, as there is no driver associated with this devices, cases like default/init pinctrl setup would never be performed by pwrseq. This becomes problem when the gpios used in pwrseq require pinctrl setup. Currently most of the common pinctrl setup is done in drivers/base/pinctrl.c by pinctrl_bind_pins(). There are two ways to solve this issue on either convert pwrseq drivers to a proper platform drivers or copy the exact code from pcintrl_bind_pins(). I prefer converting pwrseq to proper drivers so that other cases like setting up clks/parents from dt would also be possible.
