powerpc/52xx: Add missing of_node_put() in media5200.c

2022-09-05T07:28:25Z

In media5200_init_irq(), of_find_compatible_node() will return a node pointer with refcount incremented. The reference should be dropped with of_node_put() in the failure path or when it is not used anymore. Don't worry about 'fpga_np == NULL' as of_node_put() can correctly handle that.

powerpc/52xx: Mark gpt driver as not removable

2022-07-18T13:35:25Z

Returning an error code (here -EBUSY) from a remove callback doesn't prevent the driver from being unloaded. The only effect is that an error message is emitted and the driver is removed anyhow. So instead drop the remove function (which is equivalent to returning zero) and set the suppress_bind_attrs property to make it impossible to unload the driver via sysfs. This is a preparation for making platform remove callbacks return void.

powerpc/52xx: Get rid of of_node assignment

2022-06-22T02:51:49Z

Let GPIO library assign of_node from the parent device. This allows to move GPIO library and drivers to use fwnode APIs instead of being stuck with OF-only interfaces.

powerpc/mpc5xxx: Switch mpc5xxx_get_bus_frequency() to use fwnode

2022-06-22T02:51:49Z

Switch mpc5xxx_get_bus_frequency() to use fwnode in order to help cleaning up other parts of the kernel from OF specific code. No functional change intended.

do_div() does a 64-by-32 division, the 2nd parameter is a u32. gbp->ipb_freq is already a u32, there's no need to transform it to u64 before passing it to do_div().
