This commit extends the struct clk to provide information regarding the clock rate. As a result the clock tree traversal is performed at most once, and further reads are using the cached value. Signed-off-by: Lukasz Majewski <lukma@denx.de> --- Changes in v6: None Changes in v5: - Use long long to store rate value (to avoid int overflow and also return errors correctly) Changes in v4: None Changes in v3: None include/clk.h | 2 ++ 1 file changed, 2 insertions(+)
