phy: mapphone-mdm6600: Fix PM error handling in phy_mdm6600_probe

2022-04-14T05:08:39Z

The pm_runtime_enable will increase power disable depth. If the probe fails, we should use pm_runtime_disable() to balance pm_runtime_enable(). And use pm_runtime_dont_use_autosuspend() to undo pm_runtime_use_autosuspend() In the PM Runtime docs: Drivers in ->remove() callback should undo the runtime PM changes done in ->probe(). Usually this means calling pm_runtime_disable(), pm_runtime_dont_use_autosuspend() etc. We should do this in error handling.

phy: mapphone-mdm6600: Fix timeouts by adding wake-up handling

2020-02-27T04:50:40Z

We have an interrupt handler for the wake-up GPIO pin, but we're missing the code to wake-up the system. This can cause timeouts receiving data for the UART that shares the wake-up GPIO pin with the USB PHY. All we need to do is just wake the system and kick the autosuspend timeout to fix the issue.

phy: mapphone-mdm6600: Fix write timeouts with shorter GPIO toggle interval

2020-02-19T10:32:01Z

I've noticed that when writing data to the modem the writes can time out at some point eventually. Looks like kicking the modem idle GPIO every 600 ms instead of once a second fixes the issue. Note that this rate is different from our runtime PM autosuspend rate MDM6600_MODEM_IDLE_DELAY_MS that we still want to keep at 1 second, so let's add a separate define for PHY_MDM6600_IDLE_KICK_MS.
