[PATCH v4 00/14] dra7: mmc: Update mmc dt node to use sdhci-omap

[PATCH v4 00/14] dra7: mmc: Update mmc dt node to use sdhci-omap

[Kishon Vijay Abraham I]

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.

[PATCH v4 03/14] ARM: dts: dra7-mmc-iodelay: Add a new pinctrl group for clk line without pullup

[Kishon Vijay Abraham I]

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.

[PATCH v4 04/14] ARM: dts: am57xx-idk: Use pinctrl group from dra7-mmc-iodelay.dtsi to select pulldown

[Kishon Vijay Abraham I]

commit 18aa0f4bca701cb078a6 ("ARM: dts: am57xx-idk: Select pull down
for mmc1_clk line in default mode") modified mmc1_pins_default
pinctrl group in am57xx-idk-common.dtsi in order to change the CLK
line to PIN_INPUT_PULLDOWN. However instead of modifying the pinctrl
group, use the new pinctrl group "mmc1_pins_default_no_clk_pu" in
dra7-mmc-iodelay.dtsi added specifically to be used for CLK line without
external pull up.

3.3v. Use "ddr_3_3v" instead of "ddr_1_8v" to indicate DDR mode
works in 3.3v on these boards.

[PATCH v4 08/14] ARM: dts: dra72-evm-common: Add wilink8 wlan support

[Kishon Vijay Abraham I]

From: Hari Nagalla <hnagalla@ti.com>

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.

[PATCH v4 13/14] ARM: dts: dra7: Add high speed modes capability to MMC1/MMC2 dt node

[Kishon Vijay Abraham I]

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.

[PATCH v4 14/14] Documentation: ARM: Add new MMC requirements for DRA7/K2G

[Kishon Vijay Abraham I]

>From 4.18 kernel, all the MMC controller instances in DRA7
are programmed using sdhci based driver (sdhci-omap.c). Document
this new requirement here. Both omap2plus_defconfig and
multi_v7_defconfig has CONFIG_MMC_SDHCI_OMAP enabled.

Applying this series into omap-for-v4.18/dt-sdhci on top of the
immutable branch from Ulf.

Great that sounds good to me :) This way we can test and enable
it one SoC at a time.
