2019-07-08platform/x86: intel_pmc_core: Attach using APCI HID "INT33A1"Rajat Jain
Most modern platforms already have the ACPI device "INT33A1" that could be used to attach to the driver. Switch the driver to using that and thus make the intel_pmc_core.c a pure platform_driver. Some of the legacy platforms though, may still not have this ACPI device in their ACPI tables. Thus for such platforms, move the code to manually instantiate a platform_device into a new file of its own. This would instantiate the intel_pmc_core platform device and thus attach to the driver, if the ACPI device for the same ("INT33A1") is not present in a system where it should be. This was discussed here: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1966991.html Signed-off-by: Rajat Jain <rajatja@google.com> [andy: renamed to intel_pmc_core_pltdrv.c to be in align with other drivers] Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2019-07-08drm/komeda: Remove layer_split propertyDaniel Vetter
Properties are uapi like anything else, with all the usual rules regarding review, testcases, open source userspace ... Furthermore driver-private kms properties are highly discouraged, over the past few years we've realized we need to make a serious effort at better standardizing this stuff. Again this probably needs multiple pieces to solve this properly: - Instead of expecting userspace to compute this (and duplicating modeset code), the kernel driver should compute when it's necessary to enable layer_split mode to make a configuration possible. I.e. in komeda_plane_atomic_check() first try komeda_build_layer_data_flow() and if that fails, try komeda_build_layer_split_data_flow(), and set dflow.en_split accordingly. Assuming I understand somewhat correctly what this does. - If this is needed for validation then you want a debugfs file to force this one way or the other, or alternatively use ->atomic_print_state to dump such hidden driver-private state. Depends upon how you do your validation ofc.

Again this probably needs multiple pieces to solve this properly: - Instead of expecting userspace to compute this (and duplicating modeset code), the kernel driver should compute when it's possible to enable this better up/downscale mode (assuming I understood Liviu correctly on what this does) automatically. - If this is needed for validation then you want a debugfs file to force this one way or the other, or alternatively use ->atomic_print_state to dump such hidden driver-private state.

2019-07-08drm/komeda: remove slave_planes propertyDaniel Vetter
Properties are uapi like anything else, with all the usual rules regarding review, testcases, open source userspace ... Furthermore driver-private kms properties are highly discouraged, over the past few years we've realized we need to make a serious effort at better standardizing this stuff. Again this probably needs multiple pieces to solve this properly: - To make plane configuration less surprising to userspace you propably need to virtualize planes, and reorder which logical plane you map to which physical one dynamically. Instead of exposing a komeda-specific limitation to userspace and expecting them to dtrt. I think msm and rcar-du do that already (and others), if you need people to chat with or example code. - If this is needed for validation, again ->atomic_print_state and the infrastructure around that is your friend.

2019-07-08drm/komeda: Remove clock ratio propertyDaniel Vetter
Properties are uapi like anything else, with all the usual rules regarding review, testcases, open source userspace ... Furthermore driver-private kms properties are highly discouraged, over the past few years we've realized we need to make a serious effort at better standardizing this stuff. From the discussion with Liviu the solution for these here needs multiple pieces: - For being able to reliably read the memory clock we need a DT property, plus maybe DT override snippets to fix it if it's wrong. - For exposing plane limitations to userspace there's TEST_ONLY. There is a bit a gap in telling userspace better that scaling doesn't work due to limits (atm a good strategy is to retry again without scaling when adding a plane didn't work the first time around). But that needs a more generic solution, not exposing something extremely komeda specific. - If this is needed by validation tools, you can still expose it in debugfs. We have an entire nice infrastructure for debug printing of kms objects already, see the various atomic_print_state callbacks and infrastructure around them.
