In tuning mode of operation, when TBCTL[TB_EN] is set, eSDHC may report
one of the following errors :
1)Tuning error while running tuning operation where SYSCTL2[SAMPCLKSEL]
will not get set even when SYSCTL2[EXTN] is reset. OR
2)Data transaction error (e.g. IRQSTAT[DCE], IRQSTAT[DEBE]) during data
transaction errors.
This issue occurs when the data window sampled within eSDHC is in full
cycle. So, in that case, eSDHC is not able to find out the start and
end points of the data window and sets the sampling pointer at default
location (which is middle of the internal SD clock). If this sampling
point coincides with the data eye boundary, then it can result in the
above mentioned errors. Impact: Tuning mode of operation for SDR50,
SDR104 or HS200 speed modes may not work properly
Workaround: In case eSDHC reports tuning error or data errors in tuning
mode of operation, by add the erratum A008171 support to fix the issue.

Here is another TMIO MMC variant found in Socionext UniPhier SoCs.
As commit b6147490e6aa ("mmc: tmio: split core functionality, DMA and
MFD glue") said, these MMC controllers use the IP from Panasonic.
However, the MMC controller in the TMIO (Toshiba Mobile IO) MFD chip
was the first upstreamed user of this IP. The common driver code
for this IP is now called 'tmio-mmc-core' in Linux although it is a
historical misnomer.
Anyway, this driver select's MMC_TMIO_CORE to borrow the common code
from tmio-mmc-core.c
Older UniPhier SoCs (LD4, Pro4, sLD8) support the external DMA engine
like renesas_sdhi_sys_dmac.c. The difference is UniPhier SoCs use a
single DMA channel whereas Renesas chips request separate channels for
RX and TX.
Newer UniPhier SoCs (Pro5 and later) support the internal DMA engine
like renesas_sdhi_internal_dmac.c The register map is almost the same,
so I guess Renesas and Socionext use the same internal DMA hardware.
The main difference is, the register offsets are doubled for Renesas.
Renesas Socionext
SDHI UniPhier
DM_CM_DTRAN_MODE 0x820 0x410
DM_CM_DTRAN_CTRL 0x828 0x414
DM_CM_RST 0x830 0x418
DM_CM_INFO1 0x840 0x420
DM_CM_INFO1_MASK 0x848 0x424
DM_CM_INFO2 0x850 0x428
DM_CM_INFO2_MASK 0x858 0x42c
DM_DTRAN_ADDR 0x880 0x440
DM_DTRAN_ADDREX --- 0x444
This comes from the difference of host->bus_shift; 2 for Renesas SoCs,
and 1 for UniPhier SoCs. Also, the datasheet for UniPhier SoCs defines
DM_DTRAN_ADDR and DM_DTRAN_ADDREX as two separate registers.
It could be possible to factor out the DMA common code by introducing
some hooks to cope with platform quirks, but this patch does not touch
that for now.

tmio_mmc_set_clock() is full of quirks because different SoC vendors
extended this in different ways.
The original IP defines the divisor range 1/2 ... 1/512.
bit 7 is set: 1/512
bit 6 is set: 1/256
...
bit 0 is set: 1/4
all bits clear: 1/2
It is platform-dependent how to achieve the 1/1 clock.
I guess the TMIO-MFD variant uses the clock selector outside of this IP,
as far as I see tmio_core_mmc_clk_div() in drivers/mfd/tmio_core.c
I guess bit[7:0]=0xff is Renesas-specific extension.
Socionext (and Panasonic) uses bit 10 (CLKSEL) for 1/1. Also, newer
versions of UniPhier SoC variants use bit 16 for 1/1024.
host->clk_update() is only used by the Renesas variants, whereas
host->set_clk_div() is only used by the TMIO-MFD variants.
To cope with this mess, promote tmio_mmc_set_clock() to a new
platform hook ->set_clock(), and melt the old two hooks into it.

While at it, also fix up the related slot-node reference leak.

Recent Linux versions refuse to print actual virtual kernel addresses,
to not give a hint about the location of the kernel in a randomized virtual
address space. This affects the output of the sunxi MMC controller
driver, which now produces the rather uninformative line:
[ 1.482660] sunxi-mmc 1c0f000.mmc: base:0x(____ptrval____) irq:8
Since the virtual base address is not really interesting in the first
place, let's just drop this value. The same applies to Linux' notion of
the interrupt number, which is independent from the GIC SPI number.
We have the physical address as part of the DT node name, which is way
more useful for debugging purposes.
To keep a success message in the driver, we make this purpose explicit
with the word "initialized", plus print some information that is not too
obvious and that we learned while probing the device:
the maximum request size and whether it uses the new timing mode.
So the output turns into:
[ 1.750626] sunxi-mmc 1c0f000.mmc: initialized, max. request size: 16384 KB, uses new timings mode
[ 1.786699] sunxi-mmc 1c11000.mmc: initialized, max. request size: 2048 KB

In the uSDHC case (e.g. i.MX 6) clocks only get disabled if frequency
is set to 0. However, it could be that the stack asks for a frequency
change while clocks are on. In that case the function clears the
divider registers (by clearing ESDHC_CLOCK_MASK) while the clock is
enabled! This causes a short period of time where the clock is
undivided (on a i.MX 6DL a clock of 196MHz has been measured).
For older IP variants the driver disables clock by clearing some bits
in ESDHC_SYSTEM_CONTROL.
Make sure to disable card clock before changing frequency for uSDHC
IP variants too.
