Both SMP boot up and CPU Hotplug is supported. This version does not use DT but if needed this will be added as an incremental feature patch. The code is designed around CONFIG_NR_CPUS and should in theory support any number of APMUs, however due to the current DT-less static design only a single APMU is supported.

This is an intentional software limitation to cope with lacking scheduler support.

It produces the count used by the CPU local timer peripherals in the MPU cluster. The timer counts at a rate of 6.144 MHz. The ratio registers are missing for a sys-clk of 20MHZ which is used by DRA7 socs. So because of this, the counter was getting wrongly programmed for a sys-clk of 38.4Mhz(default). So adding the ratio registers for 20MHZ sys-clk.

If a module class has sysconfig, the init sequence utilizes the module register base for performing any sysc configuration. The module address space is being removed from hwmod database and retrieved from the property of the corresponding DT node. If a hwmod does not have its corresponding DT node defined and the memory address space is not defined in the corresponding omap_hwmod_ocp_if, then the module register target address space would be NULL and any sysc programming would result in a NULL pointer dereference and a kernel boot hang. Handle this scenario by checking for a valid module address space during the _init of each hwmod, and leaving it in the registered state if no module register address base is defined in either of the hwmod data or the DT data.

This register must be set to the right value by the secure rom code. Setting this register helps in propagating the right frequency value across OSes.

Instead of adding redundant hwmod data, move interconnects and hwmod similar between AM335x and AM43x to a common location. This helps in reuse on AM43x. AM335x interconnects that has difference and not present in AM43x are not moved. ocp clock of those in l4_wkup is fed from a different source for AM43x. Also pruss interconnect is different. AM335x hwmod's that has difference other than prcm register offsets (difference is in clocks of wkup_m3, control, gpio0, debugss and clock domain of l4_hs, adc_tsc as compared to AM43x) and those that are not present in AM43x are not moved.

Update register offsets at runtime based on the SoC detected to help in sharing otherwise same hwmod.

It is now updated based on SoC detection at run time, hence remove statically initialized ones.

AM43x additional ones added here are, 1. synctimer 2. timer8-11 3. ehrpwm3-5 4. spi2-4 5. gpio4-5 AM43x pruss interconnect which is different as compared to AM335x, has been taken care. And register offsets for same hwmod's shared with AM335x is different, AM43x register offsets are updated appropriately. ocp clock of those in l4_wkup is fed from "sys_clkin_ck" instead of "dpll_core_m4_div2_ck", so "ocpif" for those in AM43x l4_wkup has been added seperately. hwmod's has been added for those that have main clock (wkup_m3, control, gpio0) and clock domain (l4_hs) different from AM335x. debugss and adc_tsc that have different clocks and clockdomains repectively has not been added due to the reasons mentioned below. AM43x also has IP's like qspi, hdq1w, vpfe, des, rng, usb, dss, debugss, adc_tsc. These are not handled here due to both/either of following reasons, 1. To avoid churn; most of them don't have DT bindings, which would necessitate adding address space in hwmod, which any way would have to be removed once DT bindings happen with driver support. 2. patches would come in from sources other than the author Signed-off-by: Afzal Mohammed Acked-by: Rajendra Nayak Acked-by: Tony Lindgren Signed-off-by: Paul Walmsley --- arch/arm/mach-omap2/omap_hwmod.h | 1 + .../omap_hwmod_33xx_43xx_common_data.h | 1 + .../omap_hwmod_33xx_43xx_ipblock_data.c | 74 +++ arch/arm/mach-omap2/omap_hwmod_43xx_data.c | 619 ++++++++++++++++++ 4 files changed, 695 insertions(+) create mode 100644 arch/arm/mach-omap2/omap_hwmod_43xx_data.c diff --git a/arch/arm/mach-omap2/omap_hwmod.h b/arch/arm/mach-omap2/omap_hwmod.h index d02acf9308d3..0f97d635ff90 100644 --- a/arch/arm/mach-omap2/omap_hwmod.h +++ b/arch/arm/mach-omap2/omap_hwmod.h @@ -752,6 +752,7 @@ extern int omap44xx_hwmod_init(void);

Many of AM43x IP's and interconnects are similar as that in AM335x, hence AM335x hwmod data is being reused with necessary changes. Earlier the plan was to reuse AM335x specific PRCM code, but as AM43x PRCM register layout is much similar to OMAP4/5, AM335x PRCM is divorced and instead married with OMAP4/5 PRCM for AM43x.

In that case, of_iomap() gets called from interrupt context and hence triggers the BUG_ON in __get_vm_area_node(). Actually, since commit c1e31d1 (ARM: imx: create mxc_arch_reset_init_dt() for DT boot), imx6q/dl should try to use mxc_restart() by calling mxc_arch_reset_init_dt() beforehand, where things like of_iomap() can be done. The patch updates mxc_restart() a little bit to get it work for imx6q/dl and kill imx6q_restart() completely.

Let's move it into pm-imx6q.c, so that we can keep clock driver SoC specific and reuse pm-imx6q.c on imx6sl. In order to avoid adding another ioremap for CCM block, imx6q_pm_set_ccm_base() is created to let clock driver set up ccm_base for pm code. During the move, the unused CCGR macros get removed.

This becomes unnecessary since we can make the calls from imx6q_pm_enter() directly now for suspend. More importantly, the current call of imx6q_enable_wb() from imx6q_set_lpm() is buggy. The CLPCR register bits configured by imx6q_enable_wb() will get lost, because imx6q_set_lpm() caches the same register and write it back at the end of the function. That's why the imx6dl suspend/resume does not work currently - the wakeup from suspend triggers a reset on imx6dl. Moves the WB and RBC calls into imx6q_pm_enter() to save the state tracking and fixes above bug, so that suspend/resume can start working on imx6dl.

When SW tries to enter low power mode with following sequence, the chip will enter low power mode before A9 CPU execute WFI instruction: 1. Set CCM_CLPCR[1:0] to 2'b00; 2. ARM CPU enters WFI; 3. ARM CPU wakeup from an interrupt event, which is masked by GPC or not visible to GPC, such as interrupt from local timer; 4. Set CCM_CLPCR[1:0] to 2'b01 or 2'b10; 5. ARM CPU execute WFI. Before the last step, the chip will enter WAIT mode if CCM_CLPCR[1:0] is set to 2'b01, or enter STOP mode if CCM_CLPCR[1:0] is set to 2'b10. The patch implements a recommended workaround for this issue. 1. SW triggers irq #32(IOMUX) to be always pending manually by setting IOMUX_GPR1_GINT bit; 2. SW should then unmask it in GPC before setting CCM LPM; 3. SW should mask it right after CCM LPM is set (bit0-1 of CCM_CLPCR).
