From 2dc61587a1035b6f0ab333e5151fe89e240c7606 Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Wed, 1 Aug 2018 12:57:20 +0200 Subject: pwm: meson: Fix mux clock names [ Upstream commit b96e9eb62841c519ba1db32d036628be3cdef91f ] Current clock name looks like this: /soc/bus@ffd00000/pwm@1b000#mux0 This is bad because CCF uses the clock to create a directory in clk debugfs. With such name, the directory creation (silently) fails and the debugfs entry end up being created at the debugfs root. With this change, the clock name will now be: ffd1b000.pwm#mux0 This matches the clock naming scheme used in the ethernet and mmc driver. It also fixes the problem with debugfs.
