Changes from v3:
*) Added dra7-mmc-iodelay.dtsi to add a new pinctrl group for clk line
   without pullup to be used for dra71-evm and am57xx-idk.
*) Rename wlcore node name to wifi

This series should be merged only after [1].
[1] -> https://marc.info/?l=linux-omap&m=152482966225758&w=2

This series:
 *) Adds wilink wlan support (Now all MMC instances in DRA7 will use
    sdhci-omap)
 *) Add a new pinctrl group for clk line without pullup required for
    UHS cards to work reliably.
 *) Update README to make sure users update .config file from 4.18
    kernel.
 *) Use sdhci-omap programming model.

In the "Use sdhci-omap programming model" patch, "ti,omap4-hsmmc"
compatible is removed. This is because if both "ti,dra7-sdhci" and
"ti,omap4-hsmmc" is added and if there is probe deferral in sdhci_omap
driver, the device is binding to omap_hsmmc driver.

Once omap_hsmmc and sdhci_omap driver are feature identical,
sdhci_omap driver will be made to support omap_hsmmc binding
(including "ti,omap4-hsmmc" compatible) and omap_hsmmc driver will
be removed. Till then dt nodes with "ti,omap4-hsmmc" compatible
will use omap_hsmmc driver and "ti,dra7-sdhci" compatible will
use sdhci_omap driver.

mmc specific pinmux is selected from dra72x-mmc-iodelay.dtsi, so remove
it from dra72-evm-common.dtsi.

Add "vqmmc-supply" property for mmc2 to indicate the supply connected
to the IO lines.

During a short period when the bus voltage is switched from 3.3v to 1.8v,
(to enumerate UHS mode), the mmc module is disabled and the mmc IO lines
are kept in a state according to the programmed pad mux pull type.

According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications
Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the
host should hold CLK low for at least 5ms.

In order to keep the card line low during voltage switch, the pad mux of
mmc1_clk line should be configured to pull down.

Add a new pinctrl group for clock line without pullup to be used in boards
where mmc1_clk line is not connected to an external pullup.

commit 18aa0f4bca701cb078a6 ("ARM: dts: am57xx-idk: Select pull down

pinctrl group in am57xx-idk-common.dtsi in order to change the CLK

Include dra76x-mmc-iodelay.dtsi which has pinmux and IODelay
configuration values for the various MMC modes for am574x SoC
and use it in the pinctrl properties of MMC devicetree
nodes present in am574x-idk.dts.

The IO lines of MMC2 in am57xx-beagle-x15/am57xx-idk is connected to
3.3v. Use "ddr_3_3v" instead of "ddr_1_8v" to indicate DDR mode
works in 3.3v on these boards.

Wilink8 module is a combo wireless connectivity card based
on Texas Instrument's wl18xx solution.

Add support for the wlan capabilities of this module by muxing
the relevant mmc lines, and setting the required device-tree
data.

From: Hari Nagalla <hnagalla@ti.com>

The wilink module is a combo wireless connectivity sdio
card based on Texas Instrument's wl18xx solution. It is a
4-wire, 1.8V, embedded sdio wlan device with an external
irq line and is power-controlled by a gpio-based fixed
regulator.

Add pinmux configuration and IODelay values for MMC4.
On dra7-evm, MMC4 is used for connecting to wilink module.

While the supported UHS mode can be obtained from CAPA2
register, SD Host Controller Standard Specification
doesn't define bits for MMC's HS200 and DDR mode capability.
Add properties to indicate MMC HS200 and DDR speed mode capability in
dt node.
