thorpej | branches: 1.33.8;
Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Make the following changes:
struct device * -> device_t
struct cfdata * -> cfdata_t

device_t/softc split

peter | branches: 1.30.58; 1.30.60; 1.30.62;
Hide the bit invertion/shifting of values received from and send to the MCU
inside the j720ssp_readwrite function. This simplifies the calls to this
function a little.

| 04-Mar-2006 |
peter | branches: 1.29.2; 1.29.10;
Split the Jornada 7xx drivers for the touch-panel, keyboard, lcd control
and power management into multiple files. This removes some dirty hacks
and improves the quality of the code.
- j720kbd.c - keyboard driver
* Converted to use the hpckbd(4) interface.
* Remove the old keymap file since it's no longer used.
- j720lcd.c - lcd brightness/control/power control
- j720pwr.c - power management
* Converted to use the hpcapm(4) interface.
* Fix the battery charge status. The values are non-linear so in order
to display a reasonable charge status we use a few charge points in
a table and interpolate between that.
- j720tp.c - touch-panel driver
- j720ssp.c - SSP port (on the SA-1110)
Many thanks to cube@ and uwe@ for providing useful feedback and reviewing
the changes.

manu | - missing bits of apm
- KNF
|
| 1.9 |
| 13-Sep-2002 |
manu | fix touchpanel broken behavior:
- when moving the stylus, the cursor was updated only when the screen was
released
- when moving the stylus for too long, the kernel crashed
This was caused by improper delays in SSP read and write, and by interrupt
hammering while the screen is touched). Both led to the machine handling
interrupts all the time and been unable to schedule the X server, therefore
the lack of cursor refresh.
The problem is fixed by
- masking touchpanel interrupts as soon as we are already handling them
- creating a kernel thread (j720ssp) that takes care of keyboard and
touchpanel I/O, instead of doing it in a softintr.
- reducing delays in j720ssp_readwrite operations from 5ms to 0.1ms.
NB: If the delay in j720ssp_readwrite operation is lowered to 0.1, then
switching on the screen using the power key pushes brightness to maximum.
In order to avoid this, we introduce a wait argument to j720ssp_readwrite,
which specify how many microseconds we have to wait. j720ssp_readwrite is
called with wait = 100 everywhere except in j720lcdparam where it is called
with wait = 500. That way it works.

atatat | branches: 1.5.4;
Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

to spot.
|

| 05-Apr-2021 |
thorpej | config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.

thorpej | CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
|

thorpej | Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
|
| 1.32.78.2 |
| 21-Mar-2021 |
thorpej | CFARG_IATTR usage audit:
If a device carries only one interface attribute, there is no need
to specify it when calling config_search(); that specification is
meant only to disambiguate which interface attribute (which is a
proxy for "what kind of attach args are being used") is having
children attached. cfparent_match() will take care of ensuring that
any potential children can attach to one of the parent's iterface
attributes, and if the parent only carries one, no disambiguation is
necessary.
|
| 1.32.78.1 |
| 20-Mar-2021 |
thorpej | The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:
- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.
