commit b3855668d98cf9c6aec2db999dd27d872f8ba878 upstream.

mmc: sdhci: fix DMA configure compatibility issue when 64bit DMA mode is used.
Bayhub SD host has hardware limitation:
1.The upper 32bit address is inhibited to be written at SD Host Register
[03E
mmc: sdhci: fix DMA configure compatibility issue when 64bit DMA mode is used.
Bayhub SD host has hardware limitation:
1.The upper 32bit address is inhibited to be written at SD Host Register
[03E][13]=0 (32bits addressing) mode, is admitted to be written only at
SD Host Register [03E][13]=1 (64bits addressing) mode.
2.Because of above item#1, need to configure SD Host Register [03E][13] to
1(64bits addressing mode) before set 64bit ADMA system address's higher
32bits SD Host Register [05F~05C] if 64 bits addressing mode is used.
The hardware limitation is reasonable for below reasons:
1.Normal flow should set DMA working mode first, then do
DMA-transfer-related configuration, such as system address.
2.The hardware limitation may avoid the software to configure wrong higher
32bit address at 32bits addressing mode although it is redundant.
The change that set 32bits/64bits addressing mode before set ADMA address,
has no side-effect to other host IPs for below reason:
The setting order is reasonable and standard: DMA Mode setting first and
then DMA address setting. It meets all DMA setting sequence.

mmc: sdhci-tegra: Issue CMD and DAT resets together
In case of error condition to avoid system crash Tegra SDMMC controller
requires CMD and DAT resets issued together. SDHCI controller FSM goes
into bad state due to rapid SD card hot-plug event. Issuing reset on the
CMD FSM before DATA FSM results in kernel panic, hence add support to
issue CMD and DAT resets together.
This is applicable to Tegra186 and later chips.

kmap_local_page() is equivalent to kmap_atomic() except that it does not
disable page faults or preemption. Where possible kmap_local_page() is
preferred to kmap_atomic() - refer kernel highmem documentation.
In this case, there is no need to disable page faults or preemption, so
replace kmap_atomic() with kmap_local_page(), and, correspondingly,
kunmap_atomic() with kunmap_local().

sg_miter_next() using an sg_mapping_iter with flag SG_MITER_ATOMIC uses

mmc: sdhci: Fix voltage switch delay
Commit 20b92a30b561 ("mmc: sdhci: update signal voltage switch code")
removed voltage switch delays from sdhci because mmc core had been
enhanced to support them. However that assumed that sdhci_set_ios()
did a single clock change, which it did not, and so the delays in mmc
core, which should have come after the first clock change, were not
effective.
Fix by avoiding re-configuring UHS and preset settings when the clock
is turning on and the settings have not changed. That then also avoids
the associated clock changes, so that then sdhci_set_ios() does a single
clock change when voltage switching, and the mmc core delays become
effective.
To do that has meant keeping track of driver strength (host->drv_type),
and cases of reinitialization (host->reinit_uhs).
Note also, the 'turning_on_clk' restriction should not be necessary
but is done to minimize the impact of the change on stable kernels.
