* ARM: OMAP2+: hwmod: AM43x supportAfzal Mohammed2013-10-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add hwmod support for IP's that are present in AM43x, but not in AM335x. 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 <afzal@ti.com> Acked-by: Rajendra Nayak <rnayak@ti.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>

* ARM: OMAP2+: hwmod: rt address space index for DTAfzal Mohammed2013-07-301-0/+2
| | | | | | | | | | | | | | | | | Address space is being removed from hwmod database and DT information in <reg> property is being used. Currently the 0th index of device address space is used to map for register target address. This is not always true, eg. cpgmac has it's sysconfig in second address space. Handle it by specifying index of device address space to be used for register target. As default value of this field would be zero with static initialization, existing behaviour of using first address space for register target while using DT would be kept as such.

* ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LLRajendra Nayak2013-07-301-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+: Fix serial init for device tree based booting" stubbing out omap_serial_early_init() for Device tree based booting, there was a crash observed on AM335x based devices when hwmod does a _setup_reset() early at boot. This was rootcaused to hwmod trying to reset console uart while earlycon was using it. The way to tell hwmod not to do this is to specify the HWMOD_INIT_NO_RESET flag, which were infact set by the omap_serial_early_init() function by parsing the cmdline to identify the console device. Parsing the cmdline to identify the uart used by earlycon itself seems broken as there is nothing preventing earlycon to use a different one. This patch, instead, attempts to populate the requiste flags for hwmod based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need for cmdline parsing in the DT as well as non-DT cases to identify the uart used by earlycon.

* ARM: OMAP5: hwmod data: Create initial OMAP5 SOC hwmod dataBenoit Cousson2013-06-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Adding the hwmod data for OMAP54xx SOCs. Additional changes done on top of initial SOC data files. - The IO resource information like dma request lines, irq number and ocp address space can be populated via dt blob. So such data is stripped from OMAP5 SOC hwmod data file. - SDMA IO resource information is still kept since dmaengine work is till ongoing. Once the legacy dma platform driver becomes obsolete, SDMA io space information can be removed. - The devices like dss, aess, usb which are missing the device tree bindings, hwmod data is not added since OMAP5 is DT only build. When such devices add the dt bindings, respective hwmod data can be added along with it. With above update, we now need about ~2000 loc vs ~6000 loc with previous version of the patch for OMAP5 hwmod data file. Ofcourse with addition of few more drivers it can go upto ~2400 loc which is still better than the earlier version.

* ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in activeRajendra Nayak2013-05-191-0/+4
| | | | | | | | | | | | | | | | | | | | | Some IPs (like UART) need the sidle mode to be controlled in SW only while they are active. Once they go inactive, they need the IP to be put back in HW control so they are also wakeup capable. The flag HWMOD_SWSUP_SIDLE takes care of IPs which need the sidle mode to be *always* controlled in SWSUP. We now have a need to control IPs sidle mode in SWSUP only while its active. So define a new flag 'HWMOD_SWSUP_SIDLE_ACT' to help the framework know about these new IP requirements.

* | ARM: OMAP3: hwmod data: keep MIDLEMODE in force-standby for musbGrazvydas Ignotas2013-03-131-2/+7
|/ | | | | | | | | | | | | | | | | | | | | | For some unknown reason, allowing hwmod to control MIDLEMODE causes core_pwrdm to not hit idle states for musb in DM3730 at least. I've verified that setting any MIDLEMODE value other than "force standby" before enabling the device causes subsequent suspend attempts to fail with core_pwrdm not entering idle states, even if the driver is unloaded and "force standby" is restored before suspend attempt. To recover from this, soft reset can be used, but that's not suitable solution for suspend. Keeping the register set at force standby (reset value) makes it work and device still functions properly, as musb has driver-controlled OTG_FORCESTDBY register that controls MSTANDBY signal. Note that TI PSP kernels also have similar workarounds. This patch also fixes HWMOD_SWSUP_MSTANDBY documentation to match the actual flag name.

This fixes the following boot warning on OMAP4: omap_hwmod: aess: _wait_target_disable failed Without this patch, the AESS IP block does not indicate to the PRCM that it is idle after it is reset.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After setup/enable, some IP blocks need some additional setting to indicate the PRCM that they are inactive until they are configured. Some examples on OMAP4 include the AESS and FSUSB IP blocks. To fix this cleanly, this patch adds another optional function pointer, enable_preprogram, to the IP block's hwmod data. The function that is pointed to is called by the hwmod code immediately after the IP block is reset. This version of the patch includes a patch description fix from Felipe.

* | ARM: OMAP2+: hwmod: add support for blocking WFI when a device is activePaul Walmsley2013-01-261-0/+9
|/ | | | | | | | | | | Apparently, on some OMAPs, the MPU can't be allowed to enter WFI while certain peripherals are active. It's not clear why, and it's likely that there is simply some other bug in the driver or integration code. But since the likelihood that anyone will have the time to track these problems down in the future seems quite small, we'll provide a flag, HWMOD_BLOCK_WFI, to mark these issues in the hwmod data.
