2015-09-17ARM: OMAP2+: AM43XX: Enable autoidle for clks in am43xx_init_lateDave Gerlach1-0/+1
Add omap2_clk_enable_autoidle_all to am43xx_init_late otherwise the call to omap2_clk_disable_autoidle_all in am43xx_init_early may cause some clocks to always stay active and prevent low power mode transitions.

2015-09-16genirq: Remove irq argument from irq flow handlersThomas Gleixner1-1/+1
Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help!

2015-09-14ARM: OMAP5: Cleanup options for SoC only buildNishanth Menon1-1/+2
OMAP5 SoC has Cortex-A15 which does not use TWD timer. It uses ARCH_TIMER instead, clean up unwanted configuration and enable OMAP_INTERCONNECT and OPP which is necessary for expected functionality on the SoC.

2015-09-01ARM: OMAP2+: Fix booting if no timer parent clock is availableTony Lindgren1-6/+2
When bringing up a new SoC we needlessly prevent booting at timer init if timer clock_set_parent fails. This can fail if the system is booting on bootloader configured PLL values until the clock framework driver for the PLL is implemented. Let's just WARN instead, this will provide helpful information for anybody bringing up a new SoC what needs to be fixed. This allows to boot dm814x that's still missing the PLL driver.

2015-09-01ARM: OMAP2+: omap-device: fix race deferred probe of omap_hsmmc vs ↵Grygorii Strashko1-1/+2
omap_device_late_init Kernel fails to boot 50% of times (form build to build) with RT-patchset applied due to the following race - on late boot stages deferred_probe_work_func->omap_hsmmc_probe races with omap_device_late_ini. The same issue has been reported now on linux-next (4.3) by Keerthy [1] late_initcall - deferred_probe_initcal() tries to re-probe all pending driver's probe. - later on, some driver is probing in this case It's cpsw.c (but could be any other drivers) cpsw_init - platform_driver_register - really_probe - driver_bound - driver_deferred_probe_trigger and boot proceed. So, at this moment we have deferred_probe_work_func scheduled. late_initcall_sync - omap_device_late_init - omap_device_idle CPU1 CPU2 - deferred_probe_work_func - really_probe - omap_hsmmc_probe - pm_runtime_get_sync late_initcall_sync - omap_device_late_init if (od->_driver_status != BUS_NOTIFY_BOUND_DRIVER) { if (od->_state == OMAP_DEVICE_STATE_ENABLED) { - omap_device_idle [ops - IP is disabled] - [fail] - pm_runtime_put_sync - omap_hsmmc_runtime_suspend [ooops!] == log == omap_hsmmc 480b4000.mmc: unable to get vmmc regulator -517 davinci_mdio 48485000.mdio: davinci mdio revision 1.6 davinci_mdio 48485000.mdio: detected phy mask fffffff3 libphy: 48485000.mdio: probed davinci_mdio 48485000.mdio: phy[2]: device 48485000.mdio:02, driver unknown davinci_mdio 48485000.mdio: phy[3]: device 48485000.mdio:03, driver unknown omap_hsmmc 480b4000.mmc: unable to get vmmc regulator -517 cpsw 48484000.ethernet: Detected MACID = b4:99:4c:c7:d2:48 cpsw 48484000.ethernet: cpsw: Detected MACID = b4:99:4c:c7:d2:49 hctosys: unable to open rtc device (rtc0) omap_hsmmc 480b4000.mmc: omap_device_late_idle: enabled but no driver.

2015-08-20ARM: OMAP: wakeupgen: Restore the irq_set_type() mechanismGrygorii Strashko1-0/+1
The conversion of the wakeupgen irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The wakeupgen irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the wakeupgen irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.

2015-08-07ARM: OMAP2+: Fix power domain operations regression caused by 81xxTony Lindgren1-1/+5
I managed to mess up omap3 power domain operations with commit 7c80a3f89c51 ("ARM: OMAP2+: Add custom prwdm_operations for 81xx to support dm814x"), by default we should keep on using the omap3_pwrdm_operations, only 81xx needs custom handling. This causes omap3 PM to break so we won't hit off mode any longer causing idle power consumption go up from less than 10mW to over 50 mW.

2015-07-28clk: change clk_ops' ->determine_rate() prototypeBoris Brezillon2-35/+24
Clock rates are stored in an unsigned long field, but ->determine_rate() (which returns a rounded rate from a requested one) returns a long value (errors are reported using negative error codes), which can lead to long overflow if the clock rate exceed 2Ghz. Change ->determine_rate() prototype to return 0 or an error code, and pass a pointer to a clk_rate_request structure containing the expected target rate and the rate constraints imposed by clk users. The clk_rate_request structure might be extended in the future to contain other kind of constraints like the rounding policy, the maximum clock inaccuracy or other things that are not yet supported by the CCF (power consumption constraints ?).

2015-07-23ARM: OMAP2+: hwmod: Fix _wait_target_ready() for hwmods without syscRoger Quadros1-8/+16
For hwmods without sysc, _init_mpu_rt_base(oh) won't be called and so _find_mpu_rt_port(oh) will return NULL thus preventing ready state check on those modules after the module is enabled. This can potentially cause a bus access error if the module is accessed before the module is ready. Fix this by unconditionally calling _init_mpu_rt_base() during hwmod _init(). Do ioremap only if we need SYSC access. Eventhough _wait_target_ready() check doesn't really need MPU RT port but just the PRCM registers, we still mandate that the hwmod must have an MPU RT port if ready state check needs to be done. Else it would mean that the module is not accessible by MPU so there is no point in waiting for target to be ready. e.g. this fixes the below DCAN bus access error on AM437x-gp-evm.

Enable IO wakeup feature. This enables am437x pads to generate daisy chained wake ups(eventually generates aprcm Interrupt) especially when in low power modes. Signed-off-by: Keerthy <j-keerthy@ti.com> Reviewed-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2015-07-23ARM: OMAP4+: PRM: Add AM437x specific dataKeerthy1-1/+11
The register offsets for some of the PRM Registers are different hence populating the differing fields. This is needed to support IO wake up feature for am437x family. Signed-off-by: Keerthy <j-keerthy@ti.com> Reviewed-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2015-07-23ARM: OMAP: PRM: Remove hardcoding of IRQENABLE_MPU_2 and IRQSTATUS_MPU_2 ↵Keerthy1-18/+20
register offsets The register offsets of IRQENABLE_MPU_2 and IRQSTATUS_MPU_2 are hardcoded. This makes it difficult to reuse the code for SoCs like AM437x that have a single instance of IRQENABLE_MPU and IRQSTATUS_MPU registers. Hence handling the case using offset of 4 to accommodate single set of IRQ* registers generically.

2015-07-23Merge tag 'omap-for-v4.3/legacy-v2-signed' of ↵Olof Johansson4-905/+0
git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup Merge "drop few more legacy boards for v4.3" from Tony Lindgren: Drop more omap3 legacy board-*.c files for v4.3. This time we're dropping the board files for omap3logic and omap3pandora. The reason for dropping these now rather than later is that now we can simply revert the patches in case of unexpected issues as we are not dropping any platform data at this point. This leaves us with only the following board-*.c files: BOARD REASON NEEDED board-ldp.c Still used in RMKs boot test system board-rx51-*.c Needs /proc/atags support for user space Once we have the n900 legacy user space issues sorted out for /proc/atags and system_rev, we can drop the remaining two board-*.c files. And then one merge window after that we can drop the legacy booting support assuming no unexpected issues are found. * tag 'omap-for-v4.3/legacy-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Remove legacy booting support for Pandora ARM: OMAP2+: Remove legacy booting support for LogicPD Torpedo Signed-off-by: Olof Johansson <olof@lixom.net>

2015-07-16ARM: OMAP2+: Remove legacy booting support for PandoraTony Lindgren2-634/+0
We've been moving all omap2+ based systems to boot in device tree only mode for a few years now. Only omap3 has legacy booting support remaining. Most omap3 boards already have related arch/arm/boot/*.dts* files for booting with device tree. This board has support for device tree based booting, and we've been printing warnings about the legacy booting being deprecated for a few merge cycles now. Let's attempt to remove the legacy booting for it. The reason for removing the legacy booting support now rather than later is we can simply revert this patch if necessary if we run into some unexpected issues that are not trivial to fix for the device tree based booting.

Let's add a minimal clocks for dm814x to get it booted. This is mostly a placeholder and relies on the PLLs being on from the bootloader.
