[PATCH v2 0/3] ARM: OMAP1: ams-delta: Complete driver gpiod migration

This is a follow up of initial submission of a series consisted of 
6 changes, 3 of which have been already applied or reworkeed.

V2 changelog:
[PATCH 1/6] ARM: OMAP1: ams-delta: add GPIO lookup tables
	- already in mainline, commit 68e62a15a914
[PATCH 2/6] Input: ams_delta_serio: use GPIO lookup table
	- reworked and submitted as a series, already in linux-omap,
	  commit 68e62a15a914 ("ARM: OMAP1: ams-delta: drop GPIO lookup
	  table for serio device") followed by 9 more
[PATCH 3/6] ASoC: ams_delta: use GPIO lookup table
	- already in mainline, commit d65777d1a2cd
[PATCH 4/6] fbdev: omapfb: lcd_ams_delta: use GPIO lookup table
	- resubmitting as [PATCH v2 1/3 v2]
	v2: Remove problematic error code conversion no longer
	    needed if used on top of commit d08605a64e67 ("ARM: OMAP1:
	    ams-delta: move late devices back to init_machine")
	    and commit 8853daf3b4ac ("gpiolib: Defer on non-DT
	    find_chip_by_name() failure") already in linux-next
[PATCH 5/6] mtd: rawnand: ams-delta: use GPIO lookup table
	- resubmitting as [PATCH v2 2/3 v4]
	v2: Fix handling of devm_gpiod_get_optional() return values -
	    thanks to Andy Shevchenko.
	v3: Remove problematic error code conversion no longer needed
	    if used on top of commit d08605a64e67 ("ARM: OMAP1:
	    ams-delta: move late devices back to init_machine") and
	    commit 8853daf3b4ac ("gpiolib: Defer on non-DT
	    find_chip_by_name() failure") already in linux-next - thanks
	    to Boris Brezillon
	v4: fix style issue - thanks to Boris Brezillon
[PATCH 6/6] ARM: OMAP1: ams-delta: make board header file local to
	mach-omap1
	- resending as [PATCH v2 3/3]

Dependency on commit 8853daf3b4ac ("gpiolib: Defer on non-DT
find_chip_by_name() failure") is not critical - it is not needed for
clean build or run, it only prevents from potential future changes to
driver initializaton order during device_initcall.

I'm submitting the three patches in series because the last one depends
on the other two.

Thanks,
Janusz
