The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

The RZ/{G2L,G2LC,V2L} SMARC EVK uses Micron MT25QU412A flash and RZ/G2UL
SMARC EVK uses Renesas AT25QL128A flash. With current pin setting for
IOVF pin, 4-bit flash write fails for AT25QL128A flash. Use Hi-Z state
as the default for IOVF pin, so that spi controller driver in linux will
be independent of flash type.
To support this, during board production, the bit 4 of the NV config
register must be cleared by the bootloader for Micron flash.
Output from u-boot after clearing bit4 of NVCR register.

Replace devm_clk_get() and clk_prepare_enable() with

Fix the bug of missing clk_disable_unprepare() in .remove() by
using devm_clk_get_enabled() that can disables and unprepares
it automatically on driver detach.

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).

child nodes"
This reverts commit 23a641d5c2bce4c723fff9118a5d865ee6b9d05a.
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.

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.

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args. Make the argument
pointer to const for code safety and readability.
