net: wan: fsl_qmc_hdlc: Fix module compilation

2024-03-18T09:25:58+00:00

The fsl_qmc_driver does not compile as module:
  error: ‘qmc_hdlc_driver’ undeclared here (not in a function);
    405 | MODULE_DEVICE_TABLE(of, qmc_hdlc_driver);
        |                         ^~~~~~~~~~~~~~~

Fix the typo.

net: wan: framer/pef2256: Convert to platform remove callback returning void

2024-03-11T21:58:20+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

net: wan: fsl_qmc_hdlc: Add framer support

2024-03-11T09:36:11+00:00

Add framer support in the fsl_qmc_hdlc driver in order to be able to
signal carrier changes to the network stack based on the framer status
Also use this framer to provide information related to the E1/T1 line
interface on IF_GET_IFACE and configure the line interface according to
IF_IFACE_{E1,T1} information.

net: wan: fsl_qmc_hdlc: Add runtime timeslots changes support

2024-03-11T09:36:11+00:00

QMC channels support runtime timeslots changes but nothing is done at
the QMC HDLC driver to handle these changes.

Use existing IFACE ioctl in order to configure the timeslots to use.

net: wan: framer: make framer_class constant

2024-03-05T19:21:17+00:00

Since commit 43a7206b0963 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the framer_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.

The xlate callbacks are supposed to translate of_phandle_args to proper

pointer to const for code safety and readability.
