Add support for vmmc_aux to switch to 1.8v. Also use "iov" instead of
"vdd" to indicate io voltage. This is in preparation for adding support
for io signal voltage switch.

Add a separate function to set the voltage capabilities of the host
controller. Voltage capabilities should be set only once during
controller initialization but bus power can be changed every time there
is a voltage switch and whenever a different card is inserted.
This allows omap_hsmmc_conf_bus_power to be invoked every time there
is a voltage switch.

HCTL is now set based on ios.signal_voltage set by mmc core and not
hardcoded to 3V0 if OMAP_HSMMC_SUPPORTS_DUAL_VOLT is set. If
OMAP_HSMMC_SUPPORTS_DUAL_VOLT is set, it means HCTL can be set to either
3V0 or 1V8. And it should be set to 3V0 or 1V8 depending on
ios.signal_voltage.
Also it is now set on power mode status being changed to MMC_POWER_ON.

UHS SD card i/o data line operates at 1.8V when in UHS speed
mode.
Add support for signal voltage switch to support UHS cards.
Also, enable CIRQ before checking for CLEV/DLEV. MMC module can
sense when the clock lines and data lines are driven high by the
card, if MMC is active and CIRQ can be used to keep the MMC
module active. This is required for voltage switching to succeed
and the card to enumerate in UHS mode.

Set the clock rate of the functional clock to the max frequency
that is passed to the driver either using pdata or dt.
Also remove unnecessary setting of host->fclk to NULL.
This is in preparation for supporting high frequency modes
of operation.

MMC tuning procedure is required to support SD card
UHS1-SDR104 mode and EMMC HS200 mode.
The tuning function omap_execute_tuning() will only be
called by the MMC/SD core if the corresponding speed modes
are supported by the OMAP silicon which is set in the mmc
host "caps" field.
Add a separate function to set the UHSMS field to one of
SDR104, SDR50, DDR50, SDR25 or SDR12 depending on the
inserted SD card. This is required for tuning to succeed in
the case of SDR104/HS200 or SDR50.

ios->vdd is set only in mmc_power_up and mmc_power_off and not in
mmc_select_voltage() as mentioned in the code comment. This seems to be
legacy code that has been carried for a long time without being
tested.
This will be replaced with the correct voltage switch sequence and
populated in start_signal_voltage_switch ops to be used by mmc core
for switching voltages.

DRA7 Errata No i834: When using high speed HS200 and SDR104
cards, the functional clock for MMC module will be 192MHz.
At this frequency, the maximum obtainable timeout (DTO =0xE)
in hardware is (1/192MHz)*2^27 = 700ms. Commands taking longer
than 700ms will be affected by this small window frame and
will be timing out frequently even without a genune timeout
from the card. Workarround for this errata is use a software
timer instead of hardware timer to provide the delay requested
by the upper layer
So adding a software timer as a work around for the errata.
Instead of using software timeout only for larger delays requested
when using HS200/SDR104 cards which results in hardware and
software timer race conditions, so move all the timeout request
to use software timer when HS200/SDR104 card is connected and
use hardware timer when other type cards are connected.
Also start the software timer after queueing to DMA to ensure
we are more likely to expire within correct limits. To be ever
more sure that we won't expire this soft timer too early, we're
adding a 1000000ns slack to the data timeout requested by the
upper layer.

No functional change. Add separate case statements for certain timing
like MMC_TIMING_SD_HS and MMC_TIMING_MMC_HS even though AC12_UHSMC_RES
has to be written to the AC12 register (same as for default modes).
Also have separate case sections for MMC_TIMING_UHS_SDR104 and
MMC_TIMING_UHS_HS200 even though the same UHSMC value has to be written
to the AC12 register. This is in preparation for setting iodelay
values.

dra7 and dra72 controllers. Also create a new controller flag
"OMAP_HSMMC_REQUIRE_IODELAY" to specify all controllers that use
"ti,dra7-hsmmc" require iodealy configuration to be set.

The data manual of J6/J6 Eco recommends to set different IODELAY values
depending on the mode in which the MMC/SD is enumerated in order to
ensure IO timings are met.
Add support to set the IODELAY values depending on the various MMC
modes using the pinctrl APIs.

To: linux-arm-kernel
From: Sekhar Nori <nsekhar@ti.com>
OMAP HSMMC driver assumes that if the controller does
not support dual-volt, then it supports only 1.8V IO.
This assumption can be incorrect. For example, on K2G
MMC0 supports 3.3V IO only. AM57x Beagle-x15 and IDK
boards support only 3.3V IO on eMMC interface.
Support device-tree property "no-1-8-v" to for
controllers which are not dual-voltage and do not
support 1.8V IO.
Note that lack of support for this property has not
led to any known regression in affected platforms so
far. But it will be nice to be in sync with hardware
configuration.

The dt binding documentation of omap-hsmmc recommends using
"vmmc_aux" for IO supply lines. However
commit 0af28cc92690d8c ("ARM: dts: am57xx-beagle-x15: Add support
for rev B1") added it as "vmmc-aux". Fix it here.

On dra72/dra71 evms, mmc2 vdd/ios are connected to a common 1.8V supply
not 3.3V. Also the regulator that supplies 1.8V is different on dra71-evm
so move the supply property from common dtsi to evm specific dts files.

Add pinmux configuration for MMC module including IODELAY
values suggested in the data manual for the various supported
modes.
IOdelay data for both silicon revision 1.1 and 2.0 is
added here.
The datamanual revisions used are:
* AM572x Silicon Revision 2.0: SPRS953B, Revised November 2016
* AM572x Silicon Revision 1.1: SPRS915R, Revised November 2016

+ * a) Update of this file should typically correspond to a datamanual revision.
+ * Datamanual revision that was used should be updated in comment below.
+ * If there is no update to datamanual, do not update the values. If you
+ * need to use values different from that recommended by the datamanual
+ * for your design, then you should consider adding values to the device-
+ * -tree file for your board directly.
+ * b) We keep the mode names as close to the datamanual as possible. So
+ * if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
+ * we follow that in code too.
+ * c) If the values change between multiple revisions of silicon, we add
+ * a revision tag to both the new and old entry. Use 'rev11' for PG 1.1,
+ * 'rev20' for PG 2.0 and so on.
+ * d) The node name and node label should be the exact same string. This is
+ * to curb naming creativity and achieve consistency.

AM572x IDK and AM571x IDK boards have equivalent
design of how SD card and eMMC are connected.
The two EVMs mainly differ in IOdelay configuration
needed (because of difference in SoC used).
Move the common properties to am57xx-idk-common.dtsi
file which is common for both EVMs.

Add "max-frequency" property to MMC dt nodes and set the
maximum frequency to 192MHz for MMC1/MMC2, 64MHz for MMC3
and 192MHz for MMC4. pdata quirks must be utilized to
detect presence of rev 1.1/1.0 of silicon and adjust
maximum frequencies as per restrictions documented in i843.

Use the new compatible string "ti,dra7-hsmmc" that was specifically
added for dra7 and dra72. This is required since for dra7 and dra72
processors iodelay values has to be set unlike other processors.

On DRA7 family SoCs, MMC1 controller supports SDR104,
SDR50, DDR50, SDR25 and SDR12 UHS modes (These UHS modes
are not supported in beagle-x15 because it's not possible
to switch IO lines supply voltage to 1.8v).
MMC2 controller supports HS200 and DDR modes. (Since some of the
boards like am57xx-evm reva3, beagle-x15 and am57xx idk has
3.3v line connected to IO lines, HS200 cannot be supported
in these boards).
MMC3 controller supports SDR12, SDR25 and SDR50 modes.
MMC4 controller supports SDR12 and SDR25 modes.
Add these supported modes in device-tree file.

MMC2 interface on AM57xx IDK, connected to
onboard eMMC, has IO voltage fixed to 3.3V.
Add no-1-8-v device-tree property to mmc2 node
in the board's device-tree file to reflect
this.
Note that the AM57xx SoC itself supports
dual-voltage on MMC2. The limitation above is
due to the board.

DRA74x EVM Rev H EVM comes with revision 2.0 silicon.
However, earlier versions of EVM can come with either
revision 1.1 or revision 1.0 of silicon.
The device-tree file is written to support rev 2.0 of
silicon. pdata quirks are used to then override the
settings needed for PG 1.1 silicon.
PG 1.1 silicon has limitations w.r.t frequencies at
which MMC1/2/3 can operate as well as different IOdelay
numbers.

Enable PINCTRL_TI_IODELAY since it is required for MMC module in
DRA7 family of processors to configure "IODelay" values
depending on the enumerated MMC modes.

MMC on DRA7 SoCs require different IO Delay values to be configured
depending on the MMC mode. In order to confgiure these IO Delay values
CONFIG_PINCTRL_TI_IODELAY must be enabled. Document this dependency
here so that it can be added by anyone using custom .config.

Hmm what's the tuning ratio?

I gave this a quick try after manally applying next-20170519
after reverting 67d0687224a9 ("mm: drop HASH_ADAPT"). Looks like
something is missing as I got:
arch/arm/mach-omap2/pdata-quirks.c:445:23: error:
'struct omap_hsmmc_platform_data' has no member named 'version'
...
It's possible I messed up something while manually applying.

Yes please. Maybe send the dts parts first that are ready to
get merged, like the fixes and all the iodelay configuration.
Then the mmc driver changes as a separate set.
Then third set to follow-up and enable things once the mmc
driver changes are merged.
Regards,
Tony

For high speed modes like UHS SDR104 and HS200, sampling clock has to adjusted
according to the position of the data window and it varies depending on the
host and the card.
For this we configure the controller with phase delay from 0 to 0x7c (in steps
of 4) and send the tuning command (CMD19 or CMD21) for which the card responds
with a known pattern. We keep track of the phase delay's for which we received
the known patterns (without errors) and select one of the phase delays (3/4th
ratio from largest consecutive successful phase delay window).
sdhci driver makes use of the HW feature for tuning (no manual setting of phase
delays etc). Sdhci has an ops for platform specific tuning but that again has
to be implemented in omap_hsmmc driver.

[PATCH 13/41] mmc: host: omap_hsmmc: Add support to set IODELAY values adds
version member to 'struct omap_hsmmc_platform_data'.
