Subject: [PATCH v1 01/50] clk: samsung: add new IDs for Exynos5420 clocks

There is a need of new IDs which will be used for modeling proper hierarchy
in the Exynos54xx SoCs. Previous implementation rely on bootloader
settings, which are not configuring properly some clocks.
These IDs provide interface to set proper parents.

Hi,

Usually, when developing the clock controller driver,
define the same sequence between the definition sequence in dt-bibing
and clock driver. As I replied, if you squash patches, it is easy.

For example,
This series add clock id as following.

569 MUX(CLK_MOUT_ACLK400_ISP, "mout_aclk400_isp", mout_group1_p,
570 SRC_TOP0, 0, 2),
571 MUX(CLK_MOUT_ACLK400_MSCL, "mout_aclk400_mscl", mout_group1_p,
572 SRC_TOP0, 4, 2),
573 MUX(CLK_MOUT_ACLK400_WCORE, "mout_aclk400_wcore", mout_group1_p,
574 SRC_TOP0, 16, 2),
575 MUX(CLK_MOUT_ACLK100_NOC, "mout_aclk100_noc", mout_group1_p,
576 SRC_TOP0, 20, 2),

In case of this code, you can define the IDs as following sequentially:

#define CLK_MOUT_ACLK400_ISP ...
#define CLK_MOUT_ACLK400_MSCL ...
#define CLK_MOUT_ACLK400_WCORE ...
#define CLK_MOUT_ACLK100_NOC ...


But, this series define the ID as following:
#define CLK_MOUT_ACLK400_WCORE 662
#define CLK_MOUT_SCLK_DPLL 663
#define CLK_MOUT_ACLK100_NOC 664
#define CLK_MOUT_ACLK200_FSYS2 665
#define CLK_MOUT_PCLK200_FSYS 666
#define CLK_MOUT_ACLK200_FSYS 667
#define CLK_MOUT_ACLK400_ISP 668
#define CLK_MOUT_ACLK400_MSCL 669
#define CLK_MOUT_SCLK_MPLL 700
#define CLK_MOUT_ACLK266 701
#define CLK_MOUT_UART0 702
#define CLK_MOUT_UART1 703
#define CLK_MOUT_UART2 704
#define CLK_MOUT_UART3 7

Thank you for this example. I will align them.
