2021-01-15drivers: bus: simple-pm-bus: Fix compatibility with simple-bus for auxdataTony Lindgren
After converting am335x to probe devices with simple-pm-bus I noticed that we are not passing auxdata for of_platform_populate() like we do with simple-bus. While device tree using SoCs should no longer need platform data, there are still quite a few drivers that still need it as can be seen with git grep OF_DEV_AUXDATA. We want to have simple-pm-bus be usable as a replacement for simple-bus also for cases where OF_DEV_AUXDATA is still needed. Let's fix the issue by passing auxdata as platform data to simple-pm-bus. That way the SoCs needing this can pass the auxdata with OF_DEV_AUXDATA. And let's pass the auxdata for omaps to fix the issue for am335x. As an alternative solution, adding simple-pm-bus handling directly to drivers/of/platform.c was considered, but we would still need simple-pm-bus device driver. So passing auxdata as platform data seems like the simplest solution.

2020-02-26bus: ti-sysc: Implement SoC revision handlingTony Lindgren
We need to know SoC type and features for cases where the same SoC may be installed in various versions on the same board and would need a separate dts file otherwise for the different variants. For example, am3703 is pin compatible with omap3630, but has sgx and iva accelerators disabled. We must not try to access the sgx or iva module registers on am3703, and need to set the unavailable devices disabled early. Let's also detect omap3430 as that is needed for display subsystem (DSS) reset later on, and GP vs EMU or HS devices. Further SoC specific disabled device detection can be added as needed, such as dra71x vs dra76x rtc and usb4. Cc: Adam Ford <aford173@gmail.com> Cc: André Hentschel <nerv@dawncrow.de> Cc: H.

And related to that, we finally can remove the legacy sdma support in favor of using the dmaengine driver only. I was planning to send the sdma changes separately, but that would have produced a pile of pointless merge conflicts, so I decided it's best to resolve it locally. After all, the sdma series also ends up removing the related platform data.

2019-12-17ARM: OMAP2+: use separate IOMMU pdata to fix DRA7 IPU1 bootSuman Anna
The IPU1 MMU has been using common IOMMU pdata quirks defined and used by all IPU IOMMU devices on OMAP4 and beyond. Separate out the pdata for IPU1 MMU with the additional .set_pwrdm_constraint ops plugged in, so that the IPU1 power domain can be restricted to ON state during the boot and active period of the IPU1 remote processor. This eliminates the pre-conditions for the IPU1 boot issue as described in commit afe518400bdb ("iommu/omap: fix boot issue on remoteprocs with AMMU/Unicache"). NOTE: 1. RET is not a valid target power domain state on DRA7 platforms, and IPU power domain is normally programmed for OFF. The IPU1 still fails to boot though, and an unclearable l3_noc error is thrown currently on 4.14 kernel without this fix. This behavior is slightly different from previous 4.9 LTS kernel. 2. The fix is currently applied only to IPU1 on DRA7xx SoC, as the other affected processors on OMAP4/OMAP5/DRA7 are in domains that are not entering RET. IPU2 on DRA7 is in CORE power domain which is only programmed for ON power state. The fix can be easily scaled if these domains do hit RET in the future. 3. The issue was not seen on current DRA7 platforms if any of the DSP remote processors were booted and using one of the GPTimers 5, 6, 7 or 8 on previous 4.9 LTS kernel. This was due to the errata fix for i874 implemented in commit 1cbabcb9807e ("ARM: DRA7: clockdomain: Implement timer workaround for errata i874") which keeps the IPU1 power domain from entering RET when the timers are active. But the timer workaround did not make any difference on 4.14 kernel, and an l3_noc error was seen still without this fix.

Commit 0ed266d7ae5e ("clk: ti: omap3: cleanup unnecessary clock aliases") removed old omap3 clock framework aliases but caused omap3-rom-rng to stop working with clock not found error. Based on discussions on the mailing list it was requested by Tero Kristo that it would be best to fix this issue by probing omap3-rom-rng using device tree to provide a proper clk property. The other option would be to add back the missing clock alias, but that does not help moving things forward with removing old legacy platform_data. Let's also add a proper device tree binding and keep it together with the fix.

2019-05-28bus: ti-sysc: Add support for missing clockdomain handlingTony Lindgren
We need to let ti-sysc driver manage clockdomain autoidle for the duration of of reset, enable and idle. And we need to do it before we enable the clock and after we disable it. Currently we are still relying on platform callbacks indirectly managing clockdomain autoidle. But I noticed that for device tree only probed drivers it now happens only after we enabling the clocks and before we disable the clocks, while it should be the other way around. So far I have not noticed any issues with this though. Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle() functions for ti-sysc driver to use to manage clockdomains directly via platform data callbacks. Note that we can implement the clockdomain functions in pdata-quirks.c as for probing devices without "ti,hwmods" custom property we don't need to use the other platform data callbacks. Let's do this in one patch as there's is still an unlikely chance we may need to apply this as a fix for v5.2 for dropping legacy platform data for some devices. We also do have the option of adding back the platform data if needed in case of trouble. Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

This pushes the handling of inversion semantics and open drain settings to the GPIO descriptor and gpiolib. All affected board files are also augmented. This is especially nice since we don't have to have any confusing flags passed around to the left and right littering the fixed and GPIO regulator drivers and the regulator core. It is all just very straight-forward: the core asks the GPIO line to be asserted or deasserted and gpiolib deals with the rest depending on how the platform is configured: if the line is active low, it deals with that, if the line is open drain, it deals with that too.

2018-10-08mmc: omap_hsmmc: Delete platform data GPIO CD and WPLinus Walleij
The OMAP HSMMC driver has some elaborate and hairy handling for passing GPIO card detect and write protect lines from a boardfile into the driver: the machine defines a struct omap2_hsmmc_info that is copied into struct omap_hsmmc_platform_data by omap_hsmmc_pdata_init() in arch/arm/mach-omap2/hsmmc.c. However the .gpio_cd and .gpio_wp fields are not copied from omap2_hsmmc_info to omap_hsmmc_platform_data by omap_hsmmc_pdata_init() so they remain unused. The only platform defining omap2_hsmmc_info also define both to -1, unused. It turn out there are no boardfiles passing any valid GPIO lines into the OMAP HSMMC driver at all. And since we are not going to add any more OMAP2 boardfiles, we can delete this card detect and write protect handling altogether. This seems to also fix a bug: the card detect callback mmc_gpio_get_cd() in the slot GPIO core needs to be called by drivers utilizing slot GPIO. It appears the the boardfile quirks were not doing this right, so this would only get called for boardfiles, i.e. since no boardfile was using it, never. Just assign mmc_gpio_get_cd() unconditionally to omap_hsmmc_ops .get_cd() so card detects from the device tree works. AFAICT card detect with GPIO lines assigned from mmc_of_parse() are not working at the moment, but that is no regression since it probably never worked.

2018-09-17regulator: fixed: Convert to use GPIO descriptor onlyLinus Walleij
As we augmented the regulator core to accept a GPIO descriptor instead of a GPIO number, we can augment the fixed GPIO regulator to look up and pass that descriptor directly from device tree or board GPIO descriptor look up tables. Some boards just auto-enumerate their fixed regulator platform devices and I have assumed they get names like "fixed-regulator.0" but it's pretty hard to guess this. I need some testing from board maintainers to be sure. Other boards are straight forward, using just plain "fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the device ID. It seems the da9055 and da9211 has never got around to actually passing any enable gpio into its platform data (not the in-tree code anyway) so we can just decide to simply pass a descriptor instead. The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named "*_dummy_supply_device" while it is a very real device backed by a GPIO line. There is nothing dummy about it at all, so I renamed it with the infix *_regulator_* as part of this patch set. Intel MID portions tested by Andy.

Looks like these functions don't do anything in the mainline kernel so we can just drop it. Note that we must now also remove ir-rx51 pdata as it relies on the dummy platform data that does not do anything. And ir-rx51 is calling a pdata callback that doesn't do anything without checking if it exists first. For configuring device specific minimal latencies, the interface to use is pm_qos_add_request(). For an example, see what was done in commit 9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent glitches"). I've added some comments to ir-rx51 so people using it can add pm_qos support and test it.

As we have smartreflex driver configured in the device tree for some SoCs, we need to flip things on with a single patch to prevent both omap_device and ti-sysc to probe smartreflex.
