Instead, we need to make them available through a global alias. Clock alias modifications for EXYNOS4 specific clocks are as below. Alias for clock 'arm_clk' is 'armclk'. Alias for clock 'mout_apll' is 'mout_apll'. Alias for clock 'mout_core' is 'moutcore'. For EXYNOS4210, alias for clock 'sclk_mpll' is 'mout_mpll'. For EXYNOS4412, alias for clock 'mout_mpll_user_c' is 'mout_mpll'. Some of the clock aliases are newly defined and some are fixed up. While at it, also modify the debug messages to print the clock values appropriately. Signed-off-by: Tushar Behera --- Changes for v2: * Clocks for EXYNOS4X12 has also been modified. * Debug messages are updated to reflect the change in clock alias. * Updated commit message to better describe the changes. drivers/clk/samsung/clk-exynos4.c | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-) diff --git a/drivers/clk/samsung/clk-exynos4.c b/drivers/clk/samsung/clk-exynos4.c index addc738..1bdb882 100644 --- a/drivers/clk/samsung/clk-exynos4.c +++ b/drivers/clk/samsung/clk-exynos4.c @@ -356,8 +356,8 @@ struct samsung_fixed_rate_clock exynos4210_fixed_rate_clks[] __initdata = { /* list of mux clocks supported in all exynos4 soc's */ struct samsung_mux_clock exynos4_mux_clks[] __initdata = { - MUX_F(mout_apll, "mout_apll", mout_apll_p, SRC_CPU, 0, 1, - CLK_SET_RATE_PARENT, 0), + MUX_FA(mout_apll, "mout_apll", mout_apll_p, SRC_CPU, 0, 1, + CLK_SET_RATE_PARENT, 0, "mout_apll"), MUX(none, "mout_hdmi", mout_hdmi_p, SRC_TV, 0, 1), MUX(none, "mout_mfc1", sclk_evpll_p, SRC_MFC, 4, 1), MUX(none, "mout_mfc", mout_mfc_p, SRC_MFC, 8, 1), @@ -385,9 +385,9 @@ struct samsung_mux_clock exynos4210_mux_clks[] __initdata = { MUX(none, "mout_g2d", mout_g2d_p, E4210_SRC_IMAGE, 8, 1), MUX(none, "mout_fimd1", group1_p4210, E4210_SRC_LCD1, 0, 4), MUX(none, "mout_mipi1", group1_p4210, E4210_SRC_LCD1, 12, 4), - MUX_A(sclk_mpll, "sclk_mpll", mout_mpll_p, SRC_CPU, 8, 1, "sclk_mpll"), + MUX_A(sclk_mpll, "sclk_mpll", mout_mpll_p, SRC_CPU, 8, 1, "mout_mpll"), MUX_A(mout_core, "mout_core", mout_core_p4210, - SRC_CPU, 16, 1, "mout_core"), + SRC_CPU, 16, 1, "moutcore"), MUX_A(sclk_vpll, "sclk_vpll", sclk_vpll_p4210, SRC_TOP0, 8, 1, "sclk_vpll"), MUX(mout_fimc0, "mout_fimc0", group1_p4210, SRC_CAM, 0, 4), @@ -424,8 +424,8 @@ struct samsung_mux_clock exynos4210_mux_clks[] __initdata = { /* list of mux clocks supported in exynos4x12 soc */ struct samsung_mux_clock exynos4x12_mux_clks[] __initdata = { - MUX(mout_mpll_user_c, "mout_mpll_user_c", mout_mpll_user_p4x12, - SRC_CPU, 24, 1), + MUX_A(mout_mpll_user_c, "mout_mpll_user_c", mout_mpll_user_p4x12, + SRC_CPU, 24, 1, "mout_mpll"), MUX(none, "mout_aclk266_gps", aclk_p4412, SRC_TOP1, 4, 1), MUX(none, "mout_aclk400_mcuisp", aclk_p4412, SRC_TOP1, 8, 1), MUX(mout_mpll_user_t, "mout_mpll_user_t", mout_mpll_user_p4x12, @@ -449,7 +449,8 @@ struct samsung_mux_clock exynos4x12_mux_clks[] __initdata = { SRC_DMC, 12, 1, "sclk_mpll"), MUX_A(sclk_vpll, "sclk_vpll", mout_vpll_p, SRC_TOP0, 8, 1, "sclk_vpll"), - MUX(mout_core, "mout_core", mout_core_p4x12, SRC_CPU, 16, 1), + MUX_A(mout_core, "mout_core", mout_core_p4x12, + SRC_CPU, 16, 1, "moutcore"), MUX(mout_fimc0, "mout_fimc0", group1_p4x12, SRC_CAM, 0, 4), MUX(mout_fimc1, "mout_fimc1", group1_p4x12, SRC_CAM, 4, 4), MUX(mout_fimc2, "mout_fimc2", group1_p4x12, SRC_CAM, 8, 4), @@ -537,7 +538,7 @@ struct samsung_div_clock exynos4_div_clks[] __initdata = { DIV(none, "div_spi_pre2", "div_spi2", DIV_PERIL2, 8, 8), DIV(none, "div_audio1", "mout_audio1", DIV_PERIL4, 0, 4), DIV(none, "div_audio2", "mout_audio2", DIV_PERIL4, 16, 4), - DIV_A(arm_clk, "arm_clk", "div_core2", DIV_CPU0, 28, 3, "arm_clk"), + DIV_A(arm_clk, "arm_clk", "div_core2", DIV_CPU0, 28, 3, "armclk"), DIV_A(sclk_apll, "sclk_apll", "mout_apll", DIV_CPU0, 24, 3, "sclk_apll"), DIV_F(none, "div_mipi_pre0", "div_mipi0", DIV_LCD0, 20, 4, @@ -1070,9 +1071,9 @@ void __init exynos4_clk_init(struct device_node *np, enum exynos4_soc exynos4_so pr_info("%s clocks: sclk_apll = %ld, sclk_mpll = %ld\n" "\tsclk_epll = %ld, sclk_vpll = %ld, arm_clk = %ld\n", exynos4_soc == EXYNOS4210 ?
