The suniv (new F-series) chip has a timer with less functionality than the A10 timer, e.g. it has only 3 channels. Add a new compatible for it. As we didn't use the extra channels on A10 either now, the code needn't to be changed. The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer. Register sun4i_timer as sched_clock on it. Signed-off-by: Mesih Kilinc <mesihkilinc@gmail.com> --- drivers/clocksource/sun4i_timer.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
