ARM: SAMSUNG: fix watchdog reset issue with clk_get()

2011-09-15T04:59:58+00:00

clkdev framework uses global mutex to protect clock tree, so it is not
possible to call clk_get() in interrupt context. This patch fixes this
issue and makes system reset by watchdog call working again.

ARM: SAMSUNG: Add clkdev infrastructure

2011-07-20T10:11:28+00:00

The struct clk definition for Samsung platforms is extended to include
a instance of struct clk_lookup and a device name. When clocks are
registered using s3c24xx_register_clock function, the dev_id, con_id
and clk members are initialized with information from the struct clk
instance and struct clk_lookup member is registered.

ARM: SAMSUNG: Add a workaround for get_clock() for serial driver

2010-10-08T04:50:18+00:00

Serial drivers call get_clock() very early, before platform bus
has been set up, this requires a special check to let them get
a proper clock. Without this patch, a serial console is broken
on S5PV310 and S5PC210 boards.

ARM: SAMSUNG: Add s3c_disable_clocks() and tidy init+disable usage

2010-05-10T02:44:38+00:00

Add s3c_disable_clocks() and change the clock registration code to use
the s3c_register_clocks() followed by s3c_disable_clocks() instead of
the loops it was using.

ARM: SAMSUNG: Add error printing to s3c24xx_register_clocks

2010-01-26T08:44:33+00:00

Add an error print to s3c24xx_register_clocks to provide more useful
information when failing to register the clock.

I belive this was originally left out due to the possibility of a
problem with low-level debugging code. However, if the low-level
debug code is not functional by now there will be a whole other set of
problems being presented to the system.
