Subject: [PATCH 0043/1002] Register the clocks early during the boot process,
|
|
so that special/critical clocks can get enabled early on in the boot process
|
|
avoiding the risk of disabling a clock, pll_divider or pll when a claiming
|
|
driver fails to install propperly - maybe it needs to defer.
