Use DEFINE_SIMPLE_DEV_PM_OPS() instead of the SIMPLE_DEV_PM_OPS()
macro, along with using pm_sleep_ptr() as this driver doesn't handle
runtime PM.
This makes it possible to remove the #ifdef CONFIG_PM guard around
the suspend/resume functions.

The SDHCI on Tegra belongs to the core power domain and we're going to
enable GENPD support for the core domain. Now SDHCI must be resumed using
runtime PM API in order to initialize the SDHCI power state. The SDHCI
clock rate must be changed using OPP API that will reconfigure the power
domain performance state in accordance to the rate. Add runtime PM and OPP
support to the SDHCI driver.

If there is no driver match function, the driver core assumes that each
candidate pair (driver, device) matches, see driver_match_device().
Drop the mmc bus's match function that always returned 1 and so implements
the same behaviour as when there is no match function.

In mmc_send_op_cond(), loops are continuously performed at the same
interval of 10 ms. However the behaviour is not good for some eMMC
which can be out from a busy state earlier than 10 ms if normal.
Rather than fixing about the interval time in mmc_send_op_cond(),
let's instead convert into using the common __mmc_poll_for_busy().
The reason for adjusting the interval time is that it is important
to reduce the eMMC initialization time, especially in devices that
use eMMC as rootfs.

(CMD12) is normally initiated. But this does not work for the general

Due to recent changes to the mmc core, card quirks can be applied based

The TiWi WL1251 WiFi chip needs special setup of the sdio
interface before it can be probed.
So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c
which makes it useable only if connected to omap devices
which use the omap_hsmmc. The OpenPandora is the most promient
example.
There are plans to switch to a newer sdhci-omap driver and
retire omap_hsmmc. Hence this quirk must be reworked or moved
somewhere else. Ideally to some location that is not dependent
on the specific SoC mmc host driver.
This is achieved by the new mmc_fixup_device() option introduced
by ("mmc: allow to match the device tree to apply quirks") to match
through device tree compatible string.
This quirk will be called early right after where host->ops->init_card()
and thus omap_hsmmc_init_card() was previously called.
Note that we do not need to transplant
card->ocr = 0x80;
because we rely on ("mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO").

The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

MMC subsystem provides a way to apply quirks when a device match some

So, the drivers for these devices rely on device tree to identify the

Like the individual CCU drivers, it can be beneficial for memory
consumption of cross-platform configurations to only load the CCU core
on the relevant platform. For example, a generic arm64 kernel sees the
following improvement when building the CCU core and drivers as modules:
before:
text data bss dec hex filename
13882360 5251670 360800 19494830 12977ae vmlinux
after:
text data bss dec hex filename
13734787 5086442 360800 19182029 124b1cd vmlinux
So the result is a 390KB total reduction in kernel image size.
The one early clock provider (sun5i) requires the core to be built in.
Now that loading the MMC driver will trigger loading the CCU core, the
MMC timing mode functions do not need a compile-time fallback.

The old SD handling code was huge and could not handle all the details
which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to
another design. Have SDnH a separate clock, use the existing divider
clocks and move the errata handling from the clock driver to the SDHI
driver where it belongs.
This patch removes the old SD handling code and switch to the new one.
This updates the SDHI driver at the same time. Because the SDHI driver
can only communicate with the clock driver via clk_set_rate(), I don't
see an alternative to this flag-day-approach, so we cross subsystems
here.
The patch sadly looks messy for the CPG lib, but it is basically a huge
chunk of code removed and smaller chunks added. It looks much better
when you just view the resulting source file.

V3M handles SDnH differently than other Gen3 SoCs, so let's add a
separate entry for that. This will allow better SDnH handling in the
future.

The block layer forces a minimum segment size of PAGE_SIZE, so a segment
can be too big for the ADMA table, if PAGE_SIZE >= 64KiB. Fix by writing
multiple descriptors, noting that the ADMA table is sized for 4KiB chunks
anyway, so it will be big enough.

nr_free_buffer_pages could be exposed through mm.h instead of swap.h.
The advantage of this change is that it can reduce the obsolete
includes. For example, net/ipv4/tcp.c wouldn't need swap.h any more
since it has already included mm.h. Similarly, after checking all the
other files, it comes that tcp.c, udp.c meter.c ,... follow the same
rule, so these files can have swap.h removed too.
Moreover, after preprocessing all the files that use
nr_free_buffer_pages, it turns out that those files have already
included mm.h.Thus, we can move nr_free_buffer_pages from swap.h to mm.h
safely. This change will not affect the compilation of other files.
