Hi,
I am trying to support suspend to disk(hibernate) on Hikey with 4.4

can access them properly. Message can be seen as below:

When I was implementing my dirver, I just noticed some candidates
for cleanups. Some are required changes for my driver.
Masahiro Yamada (6):
mmc: renesas_sdhc: remove eprobe jump label
mmc: tmio: set tmio_mmc_host to driver data
mmc: tmio: use devm_ioremap_resource() instead of devm_ior
Currently, tmio_mmc_ops is static data and tmio_mmc_host_probe()
updates some hooks in the static data. This is a problem when
two or more instances call tmio_mmc_host_probe() and each of them
requests to use its own card_busy/start_signal_voltage_switch.
We can borrow a solution from sdhci_alloc
"goto eprobe" does nothing useful. Return directly.

The remove, suspend, resume hooks need tmio_mmc_host. It is tedious
to get mmc_host from the driver_data and pass it to mmc_priv().
We can directly set tmio_mmc_host to driver data to clean up the code.

mmc_of_parse() parses various DT properties and sets capability flags
accordingly. However, drivers have no chance to run platform init

The driver was full of code checking "if (x != 0)".
Replace by "if (x)" for better readability.

crypto_ahash_import() may be called either after
crypto_ahash_init() or without such call. Right now
we always internally call init() as part of
import(), thus leaking memory and mappings if the
user has already called init() herself.
Fix this by only calling init() internally if the

The driver was using a function naming scheme
including common prefixes for driver global
functions based on the code module they came from.
The combination of long names with long common
prefixes made the whole thing hard for a human
to parse.

This patch adds device tree mali node compatible with r6p2 utgard kernel driver

It can be easily used in target.dts with:

Hi Viresh, Rafael,
Without this patch, schedutil is totally broken for us - is
there any chance at all this could go in 4.14 or is it just
too late?
