This particular step is to support 120Hz panels more efficiently. This patchset adds a new table to include this new CDCLK step. Details can be found in BSpec entry 55409. Create a new sub-platform to identify RPL-U which will enable us to make the differentiation during CDCLK initialization. Furthermore, we need to make a distinction between ES (Engineering Sample) and QS (Quality Sample) parts as this change comes only to QS parts. This version of the patch does not include this change as we are yet to make a decision if this particular part needs to be upstreamed.(see comments on revision 2) Chaitanya Kumar Borah (2): drm/i915: Add RPL-U sub platform drm/i915/display: Add 480 MHz CDCLK steps for RPL-U drivers/gpu/drm/i915/display/intel_cdclk.c | 27 ++++++++++++++++++++++ drivers/gpu/drm/i915/i915_drv.h | 2 ++ drivers/gpu/drm/i915/i915_pci.c | 1 + drivers/gpu/drm/i915/intel_device_info.c | 8 +++++++ drivers/gpu/drm/i915/intel_device_info.h | 2 ++ include/drm/i915_pciids.h | 11 +++++---- 6 files changed, 47 insertions(+), 4 deletions(-)
