We might as well as fix all of them while doing the development. I do not see any advantage in mixing them up while we go through the hwmod to ti-sysc conversion. There are multiple subsystems involved, and so you have to ensure functionality is not broken with individual series during the transition. regards Suman > > -Tero > >> >> regards >> Suman >> >> [1] OMAP4: >> http://git.ti.com/gitweb/?p=rpmsg/iommu.git;a=commit;h=1979318da6f76809a5e6d652f814b2e80836aa21 >> >> [2] OMAP5: >> http://git.ti.com/gitweb/?p=rpmsg/iommu.git;a=commit;h=69b31b56ceffdec3aed5b0feaa06090f8ee318b6 >> >> [3] DRA7: >> http://git.ti.com/gitweb/?p=rpmsg/iommu.git;a=commit;h=a26129c10cda1d64bec3cd7a03b9acd447df84ea >> >> (portions of this patch content are already upstream, the delta being >> these additional flags). >> >>> >>> Signed-off-by: Tero Kristo <t-kristo@xxxxxx> >>> --- >>> drivers/clk/ti/clk-7xx.c | 8 ++++---- >>> 1 file changed, 4 insertions(+), 4 deletions(-) >>> >>> diff --git a/drivers/clk/ti/clk-7xx.c b/drivers/clk/ti/clk-7xx.c >>> index b57fe09..5208eb8 100644 >>> --- a/drivers/clk/ti/clk-7xx.c >>> +++ b/drivers/clk/ti/clk-7xx.c >>> @@ -25,7 +25,7 @@ >>> }; >>> static const struct omap_clkctrl_reg_data >>> dra7_dsp1_clkctrl_regs[] __initconst = { >>> - { DRA7_DSP1_MMU0_DSP1_CLKCTRL, NULL, CLKF_HW_SUP, >>> "dpll_dsp_m2_ck" }, >>> + { DRA7_DSP1_MMU0_DSP1_CLKCTRL, NULL, CLKF_HW_SUP | >>> CLKF_NO_IDLE_POLL, "dpll_dsp_m2_ck" }, >>> { 0 }, >>> }; >>> @@ -41,7 +41,7 @@ >>> }; >>> static const struct omap_clkctrl_reg_data >>> dra7_ipu1_clkctrl_regs[] __initconst = { >>> - { DRA7_IPU1_MMU_IPU1_CLKCTRL, dra7_mmu_ipu1_bit_data, >>> CLKF_HW_SUP, "ipu1-clkctrl:0000:24" }, >>> + { DRA7_IPU1_MMU_IPU1_CLKCTRL, dra7_mmu_ipu1_bit_data, >>> CLKF_HW_SUP | CLKF_NO_IDLE_POLL, "ipu1-clkctrl:0000:24" }, >>> { 0 }, >>> }; >>> @@ -137,7 +137,7 @@ >>> }; >>> static const struct omap_clkctrl_reg_data >>> dra7_dsp2_clkctrl_regs[] __initconst = { >>> - { DRA7_DSP2_MMU0_DSP2_CLKCTRL, NULL, CLKF_HW_SUP, >>> "dpll_dsp_m2_ck" }, >>> + { DRA7_DSP2_MMU0_DSP2_CLKCTRL, NULL, CLKF_HW_SUP | >>> CLKF_NO_IDLE_POLL, "dpll_dsp_m2_ck" }, >>> { 0 }, >>> }; >>> @@ -164,7 +164,7 @@ >>> }; >>> static const struct omap_clkctrl_reg_data >>> dra7_ipu2_clkctrl_regs[] __initconst = { >>> - { DRA7_IPU2_MMU_IPU2_CLKCTRL, NULL, CLKF_HW_SUP, >>> "dpll_core_h22x2_ck" }, >>> + { DRA7_IPU2_MMU_IPU2_CLKCTRL, NULL, CLKF_HW_SUP | >>> CLKF_NO_IDLE_POLL, "dpll_core_h22x2_ck" }, >>> { 0 }, >>> }; >>> >> > > -- > Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki. > Y-tunnus/Business ID: 0615521-4.
