af76a201c6 ARM: S5PV210: Remove usage of clk_h200 clock and add clk_hclk_msys clock
The clk_h200 represents the HCLK for the MSYS domain. This clock
is of type 'struct clk' but on V210, it is more suitable to be of
type 'struct clksrc_clk' (since it is a divided version of the
armclk). The replacement clock is renamed as clk_hclk_msys to
indicate that it represents the HCLK for MSYS domain.

This patch modifies the following.

1. Removes the usage of the clk_h200 clock.
2. Adds the new clock 'clk_hclk_msys'.
3. Adds clk_hclk_msys to the list of sysclks to be registered.
4. Modifies the hclk_msys clock rate calculation procedure to
   be based on the new clk_hclk_msys clock.

374e0bf5f9 ARM: S5PV210: Add armclk of clksrc_clk clock type
This patch modifies the following.

1. Adds arm clock 'clk_armclk' of type clksrc_clk clock type.
2. Adds arm clock to the list of system clocks 'sysclks' for
   registering it along with other system clocks.
3. Modifies the armclk clock rate calculation procedure to be
   based on the new clk_armclk clock.

c62ec6a9aa ARM: S5PV210: Rearrange assignment of clock for fout apll/mpll/epll clocks
The assignment of clock rates for fout apll/mpll/epll is moved further
up in the s5pv210_setup_clocks function because the subsequent patches
require the clock rate of fout clocks to be setup.

eb1ef1ed06 ARM: S5PV210: Register apll/mpll/epll clksrc_clk clocks
This patch modifies the following.

1. Registers the mout_apll clksrc_clk clock.

2. The mout_mpll and mout_epll clocks were registered as 'struct clk'
   types and then their parents were setup using the s3c_set_clksrc
   function. This patch reduces the two steps into one by registering
   the mout_mpll and mout_epll clocks using the s3c_register_clksrc
   function.

3. As per point 2 above, the init_parents array is no longer required.
   So the mout clocks are now put together in a new array named 'sysclks'.
   The sysclks array will list the system level clocks and more
   clocks will be added to it in the subsequent patches.

4. The clks array is left empty because of the movement of mpll and epll
   clocks into the sysclks array. It is not deleted since subsequent
   patches will add clocks into this array.

59cda52088 ARM: S5PV210: Rearrange the system clock definitions
The system clock definitions are currently defined below the
peripheral clock definitions in the V210 clock code. For the V210
clock updates that follow this patch, it is required that the
system clock definitions such as the mout_apll and mout_mpll be
defined prior to the device clock definitions. This patch
re-arranges the system clock defintions for the clock updates that
follow this patch.

0c1945d336 ARM: S5PV210: Add clock support for S5PV210
This patch adds clock support for S5PV210. This patch adds the clock
register definitions and the various system clocks in S5PV210.
Clocks that are common to other S5P SoC'c are added in the common
S5P clock support.
