2022-11-02soc: fsl: qe: Switch to use fwnode instead of of_nodeAndy Shevchenko1-1/+3
The OF node in the GPIO library is deprecated and soon will be removed. GPIO library now accepts fwnode as a firmware node, so switch the driver to use it. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2022-11-01soc: fsl: qe: Avoid using gpio_to_desc()Linus Walleij1-36/+30
The qe gpio driver is a custom API combined GPIO and pin control driver that exist outside of the pin control subsystem for historical reasons. We want to get rid of the old GPIO numberspace, so instead of calling gpio_to_desc() we get the gpio descriptor for the requested line from the device tree directly without passing through the GPIO numberspace, and then we get the gpiochip from the descriptor. Using the reference counting inside the gpio descriptor we can drop the reference counting code in this driver. A second gpiod_get() will not succeed. To obtain the local hardware offset of the GPIO line, the driver need to include the header from the gpiolib internals. This isn't pretty but it is the lesser evil compared to keeping the code as a roadblock to gpiolib refactoring. A proper solution would be to rewrite the driver as a real pin control driver with a built-in gpio_chip.

2022-10-17soc: qcom: rpmhpd: Use highest corner until sync_stateBjorn Andersson1-1/+38
In some cases the hardware that the bootloader has left configured depends on RPMH power domains for their operation up until the point where the related Linux device driver probes and can inherit that configuration, or power down the hardware gracefully. Unfortunately as Linux probes the releavant drivers in sequence there are periods during the Linux boot flow where either the genpd refcount will reach 0, or worse where the active performance_state votes does not meet the requirements of the state that the hardware was left in. One specific example of this is during boot of e.g. SM8150/SC8180X, where the display clock controller probes, without any particular performance state needs (to access its registers). This will drop the MMCX rail to MIN_SVS, which isn't sufficient to sustain the clock rates that the later probing MDP is configured to. This results in an unrecoverable system state. Handle both these cases by keeping the RPMH power-domais that are referenced voted for highest state, until sync_state indicates that all devices referencing the RPMH power-domain driver has been probed.

The remove callback is only called after probe completed successfully. In this case platform_set_drvdata() was called with a non-NULL argument and so ssp is never NULL. Also note that returning an error code from a remove callback doesn't result in the device staying bound. It's still removed and devm callbacks are called. So the memory that ssp pointed to during probe, goes away without the node being removed from ssp_list. The probable result of an early exit is accessing freed memory when the list is walked the next time. Signed-off-by: Uwe Kleine-König <(address hidden)> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
