f1619986d7 memory: emif: simplify locking with guard()
Simplify error handling (less gotos) over locks with guard().

The driver used file-scope variable 'irq_state' for storing IRQ state
with spin_lock_irqsave, so move it into respective local scopes.  This
should be equivalent, but more readable (less global variables).

c7d2f3fbdf memory: ti-aemif: Revert "memory: ti-aemif: don't needlessly iterate over child nodes"
This reverts commit 23a641d5c2.

The first-level children of the aemif node are not the device nodes (ones
containing the 'compatible' property) but the chip-select nodes which
instead have their own children.

of_platform_populate() will skip such nodes so we must indeed iterate
over the direct children of the aemif node. The problem here is that we
never call of_platform_depopulate() as it takes the root device as
argument. We only have an unpopulated chip-select nodes so we will leak
these devices if any of the calls to of_platform_populate() fails.

I don't have a batter idea right now but my patch was not correct so we
need to revert it. While at it: at least use the scoped variant of the
OF node iterator. Down the line, we should find a better solution to fix
this potential resource leak in error path.

the FMC2 is composed of several independent resources, listed below,
which can be assigned to different security and compartment domains:
 - 0: Common FMC_CFGR register.
 - 1: EBI controller for Chip Select 1.
 - 2: EBI controller for Chip Select 2.
 - 3: EBI controller for Chip Select 3.
 - 4: EBI controller for Chip Select 4.
 - 5: NAND controller.

2ff761ff29 memory: stm32-fmc2-ebi: add MP25 support
Add the support of the revision 2 of FMC2 IP.
     - PCSCNTR register has been removed,
     - CFGR register has been added,
     - the bit used to enable the IP has moved from BCR1 to CFGR,
     - the timeout for CEx deassertion has moved from PCSCNTR to BCRx,
     - the continuous clock enable has moved from BCR1 to CFGR,
     - the clk divide ratio has moved from BCR1 to CFGR.

The MP1 SoCs have only one signal to manage all the controllers (NWAIT).
The MP25 SOC has one RNB signal for the NAND controller and one NWAIT
signal for the memory controller.

Let's use a platform data structure for parameters that will differ
between MP1 and MP25.

0dc5b8abfa interconnect: constify of_phandle_args in xlate
The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args.  Make the argument

51d915cbee memory: tegra: Correct DLA client names
Some of the names for the Tegra234 DLA clients are not unique and do not
align with the name of the client ID definitions. Therefore, it is not
possible to determine the exact DLA client from messages that print the
client name. Fix this by correcting the DLA memory client names for
Tegra234 to align with the name of the corresponding memory client ID.

Note that although the client names are also used by the interconnect
framework, interconnect support for the DLA clients has not been added
and so this issue does not impact the interconnect support.

f0b203bf9b memory: emif: Drop usage of platform_driver_probe()
There are considerations to drop platform_driver_probe() as a concept
that isn't relevant any more today. It comes with an added complexity
that makes many users hold it wrong. (E.g. this driver should have
better used __init instead of __init_or_module to mark functions only
relevant to .probe() and mark the driver struct with __refdata.)

This fixes a W=1 build warning:

	WARNING: modpost: drivers/memory/emif: section mismatch in reference: emif_driver+0x4 (section: .data) -> emif_remove (section: .exit.text)

d10e03cf9a memory: emif: Simplify code handling CONFIG_OF
The first thing that of_get_memory_device_details() does is calling
of_parse_phandle(). With CONFIG_OF=n this returns NULL in a static
inline function. So the compiler can determine that
of_get_memory_device_details() also returns NULL. bloat-o-meter confirms
that this patch has no effects on the size of the generated code for
CONFIG_OF=n builds.

365fcc03b6 memory: ti-emif-pm: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
