clk: shmobile: rcar-gen2: Use kick bit to allow Z clock frequency change
06 Mar, 2014
1 commit
-
The Z clock frequency change is effective only after setting the kick
bit located in the FRQCRB register.
Without that, the CA15 CPUs clock rate will never change.Fix that by checking if the kick bit is cleared and enable it to make
the clock rate change effective. The bit is cleared automatically upon
completion.Signed-off-by: Benoit Cousson

The Nomadik debugfs screws up multiplatform boots if debugfs
is enabled on the multiplatform image, since it's a simple
initcall that is unconditionally executed and reads from certain
memory locations.Fix this by checking that the driver has been properly
initialized, so a base offset to the Nomadik SRC controller
exists, before proceeding to register debugfs files.Reported-by: Andrew Lunn

…hrijver/linux into clk-fixes
Fixes stray access to undefined registers, use of wrong clock parents &
running clocks at wrong rates. All of these issues cause regressions in
the form of boards that are unable to boot or crash and die horrible

The qspi clock divisor is incorrectly set to twice the value it should

The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.So initialize flags in this structure too.

"clk: si5351: declare all device IDs for module loading"
removed the common i2c_device_id and introduced new ones for each variant
of the clock generator. Instead of exploiting that information in the driver,
it still depends on platform_data passing the chips .variant.This removes the now redundant .variant from the platform_data and puts it in
i2c_device_id's .driver_data instead.Signed-off-by: Sebastian Hesselbarth
