* memory: omap-gpmc: Drop custom PM calls with cpu_pm notifierTony Lindgren2021-07-291-75/+118
| | | | | | | | | | | | | We can now switch over to using cpu_pm instead of custom calls and make the context save and restore functions static. Let's also move the save and restore functions to avoid adding forward declarations for them. And get rid of the static data pointer while at it.

* memory: gpmc: fix out of bounds read and dereference on gpmc_cs[]Colin Ian King2021-03-071-2/+5
| | | | | | | | | | | | | | Currently the array gpmc_cs is indexed by cs before it cs is range checked and the pointer read from this out-of-index read is dereferenced. Fix this by performing the range check on cs before the read and the following pointer dereference.

This is mostly incremental work this time. Three important things: - The FMC subsystem is deleted through my tree. This happens through GPIO as its demise was discussed in relation to a patch decoupling its GPIO implementation from the standard way of handling GPIO. As it turns out, that is not the only subsystem it reimplements and the authors think it is better do scratch it and start over using the proper kernel subsystems than try to polish the rust shiny. See the commit (ACKed by the maintainers) for details. - Arnd made a small devres patch that was ACKed by Greg and goes into the device core. - SPDX header change colissions may happen, because at times I've seen that quite a lot changed during the -rc:s in regards to SPDX. (It is good stuff, tglx has me convinced, and it is worth the occasional pain.) Apart from this is is nothing controversial or problematic. Summary: Core: - When a gpio_chip request GPIOs from itself, it can now fully control the line characteristics, both machine and consumer flags. This makes a lot of sense, but took some time before I figured out that this is how it has to work. - Several smallish documentation fixes. New drivers: - The PCA953x driver now supports the TI TCA9539. - The DaVinci driver now supports the K3 AM654 SoCs. Driver improvements: - Major overhaul and hardening of the OMAP driver by Russell King. - Starting to move some drivers to the new API passing irq_chip along with the gpio_chip when adding the gpio_chip instead of adding it separately.

| * gpio: pass lookup and descriptor flags to request_ownLinus Walleij2019-06-071-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a gpio_chip wants to request a descriptor from itself using gpiochip_request_own_desc() it needs to be able to specify fully how to use the descriptor, notably line inversion semantics. The workaround in the gpiolib.c can be removed and cases (such as SPI CS) where we need at times to request a GPIO with line inversion semantics directly on a chip for workarounds, can be fully supported with this call. Fix up some users of the API that weren't really using the last flag to set up the line as input or output properly but instead just calling direction setting explicitly after requesting the line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent commit (inadvertently?) changed how failed probe of a gpmc child node was handled. Instead of proceeding with setting up any other children as before, a single error now aborts the whole process. This change broke networking on some Overo boards due to probe failing for an unrelated nand node. This second issue should obviously be fixed, but let's restore the old behaviour of allowing child-node probe to fail to avoid further similar breakage on other systems.

Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was not in use by this code, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We don't replace module.h with init.h since the file already has that.
