Those are the registers directly accessible through the MMIO range. FW registers are exposed in panthor_fw.h.
v4: - Add the CORE_FEATURES register (needed for GPU variants) - Add Steve's R-b v3: - Add macros to extract GPU ID info - Formatting changes - Remove AS_TRANSCFG_ADRMODE_LEGACY - it doesn't exist post-CSF - Remove CSF_GPU_LATEST_FLUSH_ID_DEFAULT - Add GPU_L2_FEATURES_LINE_SIZE for extracting the GPU cache line size Co-developed-by: Steven Price <steven.pr...@arm.com> Signed-off-by: Steven Price <steven.pr...@arm.com> Signed-off-by: Boris Brezillon <boris.brezil...@collabora.com> Acked-by: Steven Price <steven.pr...@arm.com> # MIT+GPL2 relicensing,Arm Acked-by: Grant Likely <grant.lik...@linaro.org> # MIT+GPL2 relicensing,Linaro Acked-by: Boris Brezillon <boris.brezil...@collabora.com> # MIT+GPL2 relicensing,Collabora Reviewed-by: Steven Price <steven.pr...@arm.com> --- drivers/gpu/drm/panthor/panthor_regs.h | 239 +++++++++++++++++++++++++ 1 file changed, 239 insertions(+) create mode 100644 drivers/gpu/drm/panthor/panthor_regs.h diff --git a/drivers/gpu/drm/panthor/panthor_regs.h b/drivers/gpu/drm/panthor/panthor_regs.h new file mode 100644 index 000000000000..b7b3b3add166 --- /dev/null +++ b/drivers/gpu/drm/panthor/panthor_regs.h @@ -0,0 +1,239 @@ +/* SPDX-License-Identifier: GPL-2.0 or MIT */ +/* Copyright 2018 Marty E.
