| | * serial: core: Fix serial core port id, including multiport devicesTony Lindgren2023-08-112-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to fix the serial core port DEVNAME to use a port id of the hardware specific controller port instance instead of the port->line. For example, the 8250 driver sets up a number of serial8250 ports initially that can be inherited by the hardware specific driver. At that the port->line no longer decribes the port's relation to the serial core controller instance. Let's fix the issue by assigning port->port_id for each serial core controller port instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unloading a hardware specific 8250 driver can produce error "Unable to handle kernel paging request at virtual address" about ten seconds after unloading the driver. This happens on uart_hangup() calling uart_change_pm(). Turns out commit 04e82793f068 ("serial: 8250: Reinit port->pm on port specific driver unbind") was only a partial fix. If the hardware specific driver has initialized port->pm function, we need to clear port->pm too. Just reinitializing port->ops does not do this. Otherwise serial8250_pm() will call port->pm() instead of serial8250_do_pm().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After fixing the serial core port device to use port->port_id instead of port->line, unloading a hardware specific 8250 port driver started producing an error for "sysfs: cannot create duplicate filename". This is happening as we are wrongly initializing port->port_id to zero when adding back serial8250_isa_devs instances, and the serial8250:0.0 sysfs entry may already exist. For serial8250 devices, we typically have multiple devices mapped to a single driver instance. For the serial8250_isa_devs instances, the port->port_id is the same as port->line. Let's fix the issue by re-initializing port_id when adding back the serial8250_isa_devs instances in serial8250_unregister_port().

The kerneldoc for device_initialize() says we must call device_put() after calling device_initialize(). We are calling device_put() on the error path, but are missing it from the device remove path. This causes release() to never get called for the devices on remove. Let's add the missing put_device() calls for both serial ctrl and port devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While fixing DEVNAME to be more usable, I broke serial_base_match() as the ctrl and port prefix for device names seemed unnecessary. The prefixes are still needed by serial_base_match() to probe the serial base controller port, and serial tx is now broken.

Let's fix the issue for sane sysfs output, and to avoid issues addressing serial ports later on. And as we're now showing the controller id, the "ctrl" and "port" prefix for the DEVNAME become useless, we can just drop them. Let's standardize on DEVNAME:0 for controller name, where 0 is the controller id. And DEVNAME:0.0 for port name, where 0.0 are the controller id and port id.

To implement this change, the intr_target field, which is used to configure the interrupt target in the interrupt configuration register is increased from 3 bits to 4 bits. In accordance to these updates, a new intr_target_width member is introduced in msm_pingroup structure. This member stores the value of width of intr_target field in the interrupt configuration register. This value is used to dynamically calculate and generate mask for setting the intr_target field. By default, this mask is set to 3 bit wide, to ensure backward compatibility with the older targets.

NXP i.MX has two correctness fixes for the 64-bit chips, dealing with the imx93 "anatop" module and the CSI interface. On the 32-bit side, there are functional fixes for RTC, display and SD card intefaces. Rockchip fixes are for wifi support on certain boards, a eMMC stability and DT build warnings. On TI OMAP, a regulator is described in DT to avoid problems with the ethernet phy initialization.

The fix is to flush posted write after enable before reset during probe. Note that some devices also need to specify the delay after enable with ti,sysc-delay-us, but this is not needed for musb on am335x based on my tests.
