Hi,
With a big delay caused by private and professional matters,
I finaly submit the second version of the GPIO support for
Marvell Armada SoCs. The rework was HUGE. The biggest change
is dropping custom GPIO protocol and start using the generic
EMBEDDED_GPIO with all its types. I think I answered
all of the review remarks, the details can be found in the changelog
below.
Patches are available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/gpio-upstream-r20190110
I also enclose a diff between v1 and v2, which maybe can ease a bit
the effort of review:
https://pastebin.com/GvAiYfJD
I am looking forward to your feedback.
Best regards,
Marcin
Changelog:
v1->v2:
* All
- rebase on top of the master branch and Xenon changes
* 1/12
- s/AP/AP806/ in order to avoid confusion
- drop desc/DESC usage and improve variables naming
- use GPIO_CONTROLLER from EmbeddedGpio.h instead of custom MV_SOC_GPIO
- update commit message
* 2,3,4,5/12
- drop desc/DESC usage and improve variables naming
- drop reference to I2c and use GpioExpander
- improve commit logs
* 6/12
- drop desc/DESC usage and improve variables naming
- drop reference to I2c and use GpioExpander
- remove global variable - same as for other interfaces the consumer
is responsible for avoiding memory leak
* 7/12
- use MV_GPIO_ prefix
- switch to EMBEDDED_GPIO
- remove custom Marvell GPIO Protocol and types
- add subroutine to MvGpioGetProtocol and more coments to clarify the code

* 8/12
- extend error path in the entry point, rename variables
- use MV_GPIO_ prefix
- switch to EMBEDDED_GPIO
- remove custom Marvell GPIO Protocol and types
- replace '!!' expression for obtaining pin state
- remove BIT() macro
- use generic mDevicePathTemplate name
- put validate function under '#if !defined(MDEPKG_NDEBUG)' and
call from inside ASSERT_EFI_ERROR, add comment
- update commit message
- add common enum for describing controllers
- change authorship
- 9/12
- Add Leif's RB
* 10/12
- same modifications as 8/12
- use I2C flags directly and remove PCA95XX_OPERATION enum
- add common enum for describing controllers
* 11/12
- Add Leif's RB
* 12/12
- Add local headers
- Make STATIC names more generic
- s/GetInitializerForType/NonDiscoverableDeviceInitializerGet/

This patch introduces new library callback (ArmadaSoCGpioGet ()),
which dynamically allocates and fills EmbeddedGpio's
GPIO_CONTROLLER structure with the SoC description of GPIO controllers.
Because the library header is indirectly used in many modules,
update all dependencies after including EmbeddedGpio.h.

This patch extends library with GPIO devices per-board
description. Both embedded SoC controllers and
I2C IO expanders are supported. Add a helper routine
for obtaining information about the latter.

Introduce new callback that can provide information
about GPIO SoC controllers, as well as on-board
I2C IO expanders. According ArmadaSoCDescLib
ArmadaBoardDescLib routines are used for
obtaining required data.

This patch introduces a helper header that can be used by
multiple EMBEDDED_GPIO protocol producers (e.g. platform
driver or GPIO expanders). The drives are differentiated by
MV_GPIO_DRIVER_TYPE field of driver's MV_GPIO_DEVICE_PATH.
In order to ease selection of the desired GPIO controller
a helper function was added - MarvellGpioGetProtocol().

Marvell Armada 7k/8k SoCs comprise integrated GPIO controllers,
one in AP806 and two in each south bridge hardware blocks.
This patch introduces support for them. The new driver implements
a generic EMBEDDED_GPIO protocol.
In order to ease description of used GPIO pins and controllers
of the Armada 7k8k platforms, add a common enum type.

To: edk2-devel; +Cc: leif.lindholm, ard.biesheuvel, nadavh, mw, jsd, jaz, kostap
Marvell Armada 7k/8k-based platforms may use Pca95xx to extend
amount of the GPIO pins.
This patch introduces support for them. The new driver implements
a generic EMBEDDED_GPIO protocol.
In order to ease description of used PCA9XXX controllers
add a common enum type. It can be used e.g. in the board description
library to specify the expander model on a board (instead of passing
a raw number). Update relevant libraries.
Driver is based on initial work done by Allen Yan <yanwei@marvell.com>.

To abstract the initialization required for non-discoverable devices,
which is often platform specific (e.g. enable GPIO-driven power supply),
introduce a NonDiscoverableInitLib for use by the NonDiscoverable code,
for which each platform can supply its own version.
Add XHCI power supply (so called 'VBUS') enabling routines
for supported platforms (Armada70x0Db, Armada80x0Db, Armada80x0McBin).

My request on v1 was that this be refactored from a STATIC local

Instead, this space is now dynamically allocated. But none of the call
sites actually change, leading to potential memory leaks.
I don't have a problem if you prefer an alternative solution to the
one I propose, but please discuss the change first rather than
submitting a new revision containing something I didn't ask for.

Eep!
I missed this in v1 (I assumed I'd missed the new file indicator
whilst scrolling) - please move these functions out of this .h file.
https://edk2-docs.gitbooks.io/edk-ii-c-coding-standards-specification/content/v/release/2.20/5_source_files/53_include_files.html#537-include-files-shall-not-generate-code-or-define-data-variables
This makes me take a closer look at the rest of the patch ... and this
just isn't a protocol - it's a library. Please restrucure it as such
and move the header file to Include/Library rather than
Include/Protocol.

Unaddressed feedback from last time. But rereading it makes it clear
my feedback was too imprecise, apologies. The point was that "GPIO" is
not a very good choice of key to distinguish _this_ GPIO driver from
other GPIO drivers. (As well as the MV_ prefix.)
One more comment below, but it does not require code changes.
If you can just change the signature, I'm happy with this patch.

Ah, right, it's the change to EMBEDDED_GPIO that means we have two
output modes to return instead of just input or output.
Could I just ask that you're a bit more explicit about such things in
the cover letter? Would have saved me a couple of minutes of head
scratching.

Right. So we do fix the nastiness here.
But surely the original live coding was nonsense until the enum was
added?
I would lean towards breaking the changes to
Silicon/Marvell/Include/Protocol/MvGpio.h out as a separate patch and
moving that before the preceding patches that (will) depend on it.
Other than that, no issues with this patch.

Indeed, I could have asked, but didn't want to spoil your Christmas
time with questions, especially gitven it was 3+ weeks from review:/
Anyway, I tried to play with the MV_BOARD_GPIO_DESCRIPTION to be the
global variable, but was not convinced by the outcome. My biggest
objection to the global variable and checking whether it's NULL in the
consumer driver is following - until now all users of the
BoardDescProtocol 'know' and call only the relevant protocol routine,
everything what happens underneath (PCDs, variable names, etc) is
transparent.
The consumers should be responsible for avoiding the memory leaks and
this was an improvement of v2. Both MvGpioDxe and MvPca9xxxDxe have
now fixed error path an properly take care of freeing the memory after
using protocol.
Please let know if above approach is acceptable.
Best regards,
Marcin

Initially it was a header for MvGpioProtocol + this inline C addition
at the end... I will change it to the library.

Well, in the cover letter I wrote:
"The biggest change is dropping custom GPIO protocol and start using
the generic EMBEDDED_GPIO with all its types."
And in the commit log of both drivers:
"The new driver implements a generic EMBEDDED_GPIO protocol."
Wasn't it explicit enough? :)

But the call sites don't keep track of freeing it when error handling.
Which I think serves as a clear demonstrator of how magically
allocating buffers makes for difficult code to keep correct. (Which is
why the UEFI intefaces all require you to allocate a buffer and then
pass that and a size as parameters.)
So, since we are dealing with data that isn't changing, I prefer the
original design - just not the original implemenation.
So how about sticking with that, but moving the STATIC struct global
in that source file (but keeping it STATIC)?

I mean, it's fine - you've technically given all the information
needed to deduce that. But it does sort of imply that the reader knows
all EDK2 interfaces by heart. And I'm not quite there.

Good, keeping the global variable inside MvBoardDescDxe and checking
it there is a clean and easy solution (consumers won't have to bother
about the stuff additional to calling the protocol and error handling
will be simpler).
How about on top of the file I add a section for global varibles (IMO
it's worth to modify other interfaces to that scheme later) and call
it:
STATIC MV_BOARD_GPIO_DESCRIPTION gGpioDescription;
?
