clk: mvebu: add Armada 375 support to the corediv clock driver (e4aec65c) · Commits · 戴 / test

This commit adds support for the Core Divider clocks of the Armada 375. Compared to Armada 370 and XP the Core Divider clocks of the 375 cannot be gated: only their ratio can be changed. This is reflected by the fact that the enable, disable and is_enabled clock operations are not defined, and that the enable_bit_offset field is also undefined. Signed-off-by:
