bus: ti-sysc: Fix timer handling with drop pm_runtime_irq_safe()

2019-01-29T15:41:15Z

Commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe them with ti-sysc") started producing a warning for pwm-omap-dmtimer: WARNING: CPU: 0 PID: 77 at drivers/bus/omap_l3_noc.c:147 l3_interrupt_handler+0x2f8/0x388 44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4PER2 (Idle): Data Access in Supervisor mode during Functional access ... __pm_runtime_idle omap_dm_timer_disable pwm_omap_dmtimer_start pwm_omap_dmtimer_enable pwm_apply_state pwm_vibrator_start pwm_vibrator_play_work This is because the timer that pwm-omap-dmtimer is using is now being probed with ti-sysc interconnect target module instead of omap_device and the ti-sysc quirk for SYSC_QUIRK_LEGACY_IDLE is not fully compatible with what omap_device has been doing. We could fix this by reverting the timer changes and have the timer probe again with omap_device. Or we could add more quirk handling to ti-sysc driver. But as these options don't work nicely as longer term solutions, let's just make timers probe with ti-sysc without any quirks. To do this, all we need to do is remove quirks for timers for ti-sysc, and drop the bogus pm_runtime_irq_safe() flag for timer-ti-dm. We should not use pm_runtime_irq_safe() anyways for drivers as it will take a permanent use count on the parent device blocking the parent devices from idling and has been forcing ti-sysc driver to use a quirk flag. Note that we will move the timer data to DEBUG section later on in clean-up patches.

Few more omap driver fixes and improvments for v4.21 merge window This series of changes improves the TI module flag handling to allow booting with older dts files until the module flags have been moved to the interconnect target module level. And there's a of_node_name_eq() clean-up patch from Rob Herring for the GPMC driver. * tag 'omap-for-v4.21/driver-part2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: memory: omap-gpmc: Use of_node_name_eq for node name comparisons bus: ti-sysc: Check for no-reset and no-idle flags at the child level ARM: OMAP2+: Check also the first dts child for hwmod flags Signed-off-by: Olof Johansson

bus: ti-sysc: Check for no-reset and no-idle flags at the child level

2018-12-10T22:11:26Z

With ti-sysc, we need to now have the device tree properties for ti,no-reset-on-init and ti,no-idle-on-init at the module level instead of the child device level. Let's check for these properties at the child device level to enable quirks, and warn about moving the properties to the module level. Otherwise am335x-evm based boards tagging gpio1 with ti,no-reset-on-init will have their DDR power disabled if wired up in such a tricky way. Note that this should not be an issue for earlier kernels as we don't rely on this until the dts files have been updated to probe with ti-sysc interconnect target driver.

bus: ti-sysc: Add mcasp optional clocks flag

2018-11-15T22:46:53Z

We have OPT_CLKS_NEEDED in legacy platform data, but it's missing from the ti-sysc driver for device tree based configuration. In order to pass OPT_CLKS_NEEDED quirk flag we need to update omap4 module data and add a new compatible for dra7 as the module layout is different from sysc_regbits_omap4_mcasp.
