adapt the DIU clock initialization to the COMMON_CLK approach: device tree based clock lookup, prepare and unprepare for clocks, work with frequencies not dividers, call the appropriate clk_*() routines and don't access CCM registers the "best clock" determination now completely relies on the platform's clock driver to pick a frequency close to what the caller requests, and merely checks whether the desired frequency was met (fits the tolerance of the monitor) this approach shall succeed upon first try in the usual case, will test a few less desirable yet acceptable frequencies in edge cases, and will fallback to "best effort" if none of the previously tried frequencies pass the test provide a fallback clock lookup approach in case the OF based clock lookup for the DIU fails, this allows for successful operation in the presence of an outdated device tree which lacks clock specs Cc: Anatolij Gustschin <agust@denx.de> Cc: linuxppc-dev@lists.ozlabs.org Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de> |
