19206b1742 ARM: SAMSUNG: Add new s3c-sdhci card detection methods for Samsung SoCs
On some Samsung SoCs not all SDHCI controllers have card detect (CD)
line. For some embedded designs it is not even needed, because ususally
the device (like SDIO flash memory or wifi controller) is permanently
wired to the controller. There are also systems which have a card detect
line connected to some of the external interrupt lines or the presence
of the card depends on some other actions (like enabling a power
regulator).

This patch adds all required changes to platform support code, so
another patch, which extends the driver with support for the new card
detection methods can be applied.

154d62e4cd ARM: S5PV210: Correct clock register properties
1. Corrected shift values of I2S and UART clocks (CLK_GATE_IP3), which were
defined incorrectly.

2. Corrected shift values of sclk_audio, uclk1, sclk_fimd, sclk_mmc,
sclk_spi, sclk_pwm, which had duplicated .enable/.ctrlbit with their
twins defined in struct clk init_clocks_disable[] and struct clk
init_clocks[]. We've changed their .enable/.ctrlbit to use CLK_SRC_MASK
register to avoid the duplicated clock problem described below.

NOTE: Duplicated Clock Problem
Please note that each clock definition should access different control
register; otherwise, the system may suffer lockups. For example, if we
have two clock definitions "a" and "b" which access the same register
(and the shift value). Then, when we do:

	module A
	clk = clk_get("a");
	clk->clk_enable(clk);

	module B (context switch)
	clk = clk_get("b");
	clk->clk_enable(clk);
	do something with clk.
	clk->clk_disable(clk);

	module A (context switch)
	do something with clk
	* At this point, the system may hang.

Therefore, there should be no clock definitions with the same contol
register/shift. If we need to create "aliases", then, creating child
clocks sharing the clock should be fine.

3. Corrected other sclk_* shift values and access registers.

5fae405838 ARM: S5P: Fix the platform external interrupt issues.
This patch does the following:

1. Corrects the common platform code for external interrupts for using the
   VIC mask/unmask bits also.
2. Moves the common defines related to external interrupt for plat-s5p
   to common files.
3. Based on the new common defines, corresponding changes are made in the
   affected platforms (S5P6440, S5P6442 and S5PC100).

664f5b2065 ARM: S5PV210: Fix clk_get_rate issue with the clk_h100 clock
The clk_h100 clock represents the IMEM clock for the MSYS domain.
This clock rate of this clock is always half of the hclk_msys clock.
There is an issue when getting the clock rate of the clk_h100 clock
(clock get_rate hclk_h100 always returns clock rate that is equal to
the hclk_msys clock rate).

This patch modifies the following.

1. Moves the definition of the clk_h100 clock into the 'init_clocks'
   list with the appropriate parent, ctrlbit, enable and ops fields.

2. The name of the clock is changed from 'clk_h100' to 'hclk_imem'
   to represent more clearly that is represents the IMEM clock in
   the MSYS domain.

3. The function to get the clock rate of the hclk_imem clock is added.

1. Remove definitions and usage of 'clk_h133' clock.
2. Adds 'clk_hclk_psys' clock which is of type 'struct clksrc_clk'.
3. Replace all usage of clk_h133 with clk_hclk_psys clock.
4. Adds clk_hclk_psys into list of clocks to be registered.
5. Removes the clock rate calculation of hclk133 and replaces
   it with code that derives the HCLK PSYS clock rate from
   the clk_hclk_psys clock.
6. Modify printing of the system clock rates.

0fe967a1ca ARM: S5PV210: Remove usage of clk_h166 and add clk_hclk_dsys clock
The clk_h166 clock, which is the HCLK clock for DSYS domain, is of
type 'struct clk' whereas on S5PV210, this clock is suitable to be
of type clksrc_clk clock (since it has a choice of clock source
and a pre-divider). So this patch replaces the 'struct clk' type
clock to 'struct clksrc_clk' type clock for the HCLK DSYS clock.

This patch modifies the following.

1. Remove definitions and usage of 'clk_h166' clock.

2. Adds 'clk_sclk_a2m' clock which is one of possible parent clock
   sources for the DSYS HCLK clock.

3. Adds 'clk_hclk_dsys' clock which is of type 'struct clksrc_clk'.

4. Replace all usage of clk_h166 with clk_hclk_dsys clock.

5. Adds clk_sclk_a2m and clk_hclk_dsys into list of clocks to
   be registered.

6. Removes the clock rate calculation of hclk166 and replaces
   it with code that derives the HCLK DSYS clock rate from
   the clk_hclk_dsys clock.

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.
