[ Upstream commit fb59ee37cfe20d10d19568899d1458a58361246c ]
If UHS speed modes are enabled, a compatible SD card switches down to
1.8V during enumeration. If after this a software reboot/crash takes
place and on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.
The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the
card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and
am57xx-evms don't have this capability, disable voltage switching for
these boards.
The major effect of this is that the maximum supported speed
mode is now high speed(50 MHz) down from SDR104(200 MHz).
commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage
switching for SD card") did this only for idk boards. Do it for all
affected boards.

TRM says PWMSS_SYSCONFIG bit for SOFTRESET changes to zero when
reset is completed. Let's configure it as otherwise we get warnings
on boot when we check the data against dts provided data. Eventually
the legacy platform data will be just dropped, but let's fix the
warning first.

[ Upstream commit 45da5e09dd32fa98c32eaafe2513db6bd75e2f4f ]
We have errata i688 workaround produce warnings on SoCs other than
omap4 and omap5:
omap4_sram_init:Unable to allocate sram needed to handle errata I688
omap4_sram_init:Unable to get sram pool needed to handle errata I688
This is happening because there is no ti,omap4-mpu node, or no SRAM
to configure for the other SoCs, so let's remove the warning based
on the SoC revision checks.
As nobody has complained it seems that the other SoC variants do not
need this workaround.

default, hs, sdr12 and sdr25 modes use iodelay values given in
MMC3_MANUAL1. Set the MODE_SELECT bit for these so that manual mode is
selected and correct iodelay values can be configured.

[ Upstream commit fa8397e45c64e60c80373bc19ee56e42a6bed9b6 ]
Non-serio path of Amstrad Delta FIQ deferred handler depended on
irq_ack() method provided by OMAP GPIO driver. That method has been
removed by commit 693de831c6e5 ("gpio: omap: remove irq_ack method").
Remove useless code from the deferred handler and reimplement the
missing operation inside the base FIQ handler.
Should another dependency - irq_unmask() - be ever removed from the OMAP
GPIO driver, WARN once if missing.
