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