the .get_clock() callback is run from probe() and might allocate resources, introduce a .put_clock() callback that is run from remove() to undo any allocation activities prepare and enable the clocks in open(), disable and unprepare the clocks in close() if clocks were acquired during probe(), to not assume knowledge about which activities are done in probe() and remove() use devm_get_clk() to lookup the SYS and REF clocks, to have the clocks put upon device shutdown store pointers to data structures upon successful allocation already instead of deferral until complete setup, such that subroutines in the setup sequence may access those data structures as well to track their resource acquisition since clock allocation remains optional, the release callback as well as the enable/disable calls in open/close are optional as well Cc: linux-can@vger.kernel.org Cc: netdev@vger.kernel.org Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |
