bus: ti-sysc: Handle module unlock quirk needed for some RTC

2020-07-22T07:32:58Z

[ Upstream commit e8639e1c986a8a9d0f94549170f6db579376c3ae ] The RTC modules on am3 and am4 need quirk handling to unlock and lock them for reset so let's add the quirk handling based on what we already have for legacy platform data. In later patches we will simply drop the RTC related platform data and the old quirk handling. Signed-off-by: Tony Lindgren Signed-off-by: Sasha Levin

bus: ti-sysc: Implement quirk handling for CLKDM_NOAUTO

2020-02-24T07:36:35Z

[ Upstream commit 94f6345712b37e4bb23cb265ce4c65b9d177e75a ] For dra7 dcan and dwc3 instances we need to block clockdomain autoidle. Let's do this with CLKDM_NOAUTO quirk flag and enable it for dcan and dwc3. Cc: Keerthy Cc: Roger Quadros Cc: Tero Kristo Signed-off-by: Tony Lindgren Signed-off-by: Sasha Levin

bus: ti-sysc: Fix missing force mstandby quirk handling

2020-02-01T09:34:51Z

[ Upstream commit 93c60483b5feefced92b869d5f97769495bc6313 ] Commit 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for musb") added quirk handling for mstandby quirk but did not consider that we also need a quirk variant for SYSC_QUIRK_FORCE_MSTANDBY. We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to additionally also configure no-idle mode when enabled.

bus: ti-sysc: Add module enable quirk for audio AESS

[ Upstream commit 020003f763e24e4ed0bb3d8909f3940891536d5d ] We must set the autogating bit on enable for AESS (Audio Engine SubSystem) when probed with ti-sysc interconnect target module driver. Otherwise it won't idle properly. Cc: Peter Ujfalusi Tested-by: Peter Ujfalusi Signed-off-by: Tony Lindgren Signed-off-by: Sasha Levin

A few fields in various structures is missing the corresponding kerneldoc comments. Add them. Also, fixed the comment for sidlemodes. Signed-off-by: Suman Anna Acked-by: Roger Quadros Signed-off-by: Tony Lindgren

bus: ti-sysc: Switch to SPDX license identifier

2019-08-13T11:13:32Z

Use the appropriate SPDX license identifier in the TI sysc interconnect target driver source files and drop the previous boilerplate license text. Also, add the the SPDX license identifier in the associated ti-sysc header files. Signed-off-by: Suman Anna Acked-by: Roger Quadros Signed-off-by: Tony Lindgren

bus: ti-sysc: Add support for module specific reset quirks

2019-06-10T11:52:22Z

Some older interconnect target modules need module internal clock toggling quirks to reset properly. We've been doing this in the platform code earlier, but need to be able to it directly in the ti-sysc driver when we no longer rely on on the platform code. Let's add reset handling for 1-wire, i2c and watchdog. Later on we can add more modules like msdi and dss as they get tested. For dra7 pcie, we should be able to just use the rstctrl reset driver when available. Signed-off-by: Tony Lindgren

bus: ti-sysc: Make OCP reset work for sysstatus and sysconfig reset bits

2019-05-28T12:19:15Z

We've had minimal OCP softreset support in ti-sysc interconnect target module driver only used for MCAN driver so far. But it turns out that MCAN has the sysstatus register resetdone bit inverted compared to most other modules. Let's make OCP softreset work for other typical cases with reset status in sysstatus or sysconfig register so we can use the new functions for sysc_enable_module() and sysc_disable_module() without "ti,hwmods" property in the following patches.

bus: ti-sysc: Add support for missing clockdomain handling

2019-05-28T12:19:14Z

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 Signed-off-by: Tony Lindgren
