linux-clk, linux-omap
Subsystem:
arm port, omap2+ support, the rest · Maintainers:
Russell King, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds
This avoids the need to add most of the clock aliases under drivers/clk/ti/clk-xyz.c files. Signed-off-by: Tero Kristo <redacted> --- arch/arm/mach-omap2/omap_device.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-)
