Hi, Just an initial comment to this patch, this is somewhat experimental and I think we should agree what registers will actually be saved here and what should be left for drivers. CM_CLKSEL4 is for DPLL5 which is used by USB. Two of the CLKEN registers are more interesting. -Tero >-----Original Message----- >From: linux-omap-owner@xxxxxxxxxxxxxxx >[mailto:linux-omap-owner@xxxxxxxxxxxxxxx] On Behalf Of ext Tero Kristo >Sent: 19 November, 2008 11:32 >To: linux-omap@xxxxxxxxxxxxxxx >Subject: [PATCH] PM: Added three PLL registers to the PRCM context save > >These registers are now also saved: > CM_CLKSEL4 > CM_CLKEN > CM_CLKEN2 > >Signed-off-by: Tero Kristo <tero.kristo@xxxxxxxxx> >--- > arch/arm/mach-omap2/prcm.c | 14 ++++++++++++++ > 1 files changed, 14 insertions(+), 0 deletions(-) > >diff --git a/arch/arm/mach-omap2/prcm.c >b/arch/arm/mach-omap2/prcm.c index d5a1e4b..c64b668 100644 >--- a/arch/arm/mach-omap2/prcm.c >+++ b/arch/arm/mach-omap2/prcm.c >@@ -46,7 +46,10 @@ struct omap3_prcm_regs { > u32 emu_cm_clksel; > u32 emu_cm_clkstctrl; > u32 pll_cm_autoidle2; >+ u32 pll_cm_clksel4; > u32 pll_cm_clksel5; >+ u32 pll_cm_clken; >+ u32 pll_cm_clken2; > u32 cm_polctrl; > u32 iva2_cm_fclken; > u32 core_cm_fclken1; >@@ -233,8 +236,14 @@ void omap3_prcm_save_context(void) > cm_read_mod_reg(OMAP3430_EMU_MOD, >CM_CLKSTCTRL); > prcm_context.pll_cm_autoidle2 = > cm_read_mod_reg(PLL_MOD, CM_AUTOIDLE2); >+ prcm_context.pll_cm_clksel4 = >+ cm_read_mod_reg(PLL_MOD, >OMAP3430ES2_CM_CLKSEL4); > prcm_context.pll_cm_clksel5 = > cm_read_mod_reg(PLL_MOD, >OMAP3430ES2_CM_CLKSEL5); >+ prcm_context.pll_cm_clken = >+ cm_read_mod_reg(PLL_MOD, CM_CLKEN); >+ prcm_context.pll_cm_clken2 = >+ cm_read_mod_reg(PLL_MOD, OMAP3430ES2_CM_CLKEN2); > prcm_context.cm_polctrl = __raw_readl(OMAP3430_CM_POLCTRL); > prcm_context.iva2_cm_fclken = > cm_read_mod_reg(OMAP3430_IVA2_MOD, >CM_FCLKEN); @@ -380,8 +389,13 @@ void omap3_prcm_restore_context(void) > CM_CLKSTCTRL); > cm_write_mod_reg(prcm_context.pll_cm_autoidle2, PLL_MOD, > CM_AUTOIDLE2); >+ cm_write_mod_reg(prcm_context.pll_cm_clksel4, PLL_MOD, >+ OMAP3430ES2_CM_CLKSEL4); > cm_write_mod_reg(prcm_context.pll_cm_clksel5, PLL_MOD, > OMAP3430ES2_CM_CLKSEL5); >+ cm_write_mod_reg(prcm_context.pll_cm_clken, PLL_MOD, CM_CLKEN); >+ cm_write_mod_reg(prcm_context.pll_cm_clken2, PLL_MOD, >+ OMAP3430ES2_CM_CLKEN2); > __raw_writel(prcm_context.cm_polctrl, OMAP3430_CM_POLCTRL); > cm_write_mod_reg(prcm_context.iva2_cm_fclken, OMAP3430_IVA2_MOD, > CM_FCLKEN); >-- >1.5.4.3 > >-- >To unsubscribe from this list: send the line "unsubscribe >linux-omap" in the body of a message to >majordomo@xxxxxxxxxxxxxxx More majordomo info at >http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
