mtd: onenand: omap2: Configure driver from DT

2018-01-12T15:41:15+00:00

Move away from platform data configuration and use pure DT approach.

Use generic probe function to deal with OneNAND node and remove now useless
gpmc_probe_onenand_child function. Import sync mode timing calculation
function from mach-omap2/gpmc-onenand.c

ARM: OMAP2+: Remove legacy gpmc-nand.c

2017-02-28T17:08:33+00:00

This code is no longer used and can be removed as we
are using device tree.

Removing this code also removes a dependency between
drivers/mtd and arch/arm/mach-omap2 making furhter driver
changes easier.

ARM: OMAP2+: gpmc-onenand: propagate error on initialization failure

gpmc_probe_onenand_child returns success even on gpmc_onenand_init
failure. Fix that.

memory: omap-gpmc: Implement IRQ domain for NAND IRQs

2016-04-15T08:52:28+00:00

GPMC provides 2 interrupts for NAND use. i.e. fifoevent and termcount.
Use IRQ domain for this. NAND device tree node can then
get the necessary interrupts by using gpmc as the interrupt parent.

Legacy boot uses gpmc_get_client_irq to get the
NAND interrupts from the GPMC IRQ domain.
Get rid of custom bitmasks and use IRQ domain for that
as well.

memory: omap-gpmc: Introduce GPMC to NAND interface

2016-04-15T08:51:34+00:00

The OMAP GPMC module has certain registers dedicated for NAND
access and some NAND bits mixed with other GPMC functionality.

For the NAND dedicated registers we have the struct gpmc_nand_regs.

The NAND driver needs to access NAND specific bits from the
following non-dedicated registers
- EMPTYWRITEBUFFERSTATUS from GPMC_STATUS

For accessing these bits we introduce the struct gpmc_nand_ops.

Add gpmc_omap_get_nand_ops() that returns the gpmc_nand_ops along
with updating the gpmc_nand_regs. This API will be called by the
OMAP NAND driver to access the necessary bits in GPMC register space.

ARM: OMAP2+: gpmc: Add platform data

2016-04-15T08:50:44+00:00

Add a platform data structure for GPMC. It contains all the necessary
platform information that needs to be passed from platform init code
to GPMC driver.

memory: omap-gpmc: Add support for AAD timings

2016-02-08T14:22:03+00:00

In order to support extended timings parameters on hardware supporting the
"AAD" mode like the AM335x or DM816x, add these entries into the GPMC driver
if the hardware is capable.

Tested on DM816x and AM335x.
