Add driver for the Qualcomm MSM8974 interconnect providers that support
setting system bandwidth requirements between various network-on-chip
fabrics.
I marked this as a PATCH RFC since I'm not able to write to all of the
master IDs with qcom_icc_rpm_smd_send(). I included tables below that
shows which of the 20 master IDs that I'm able to activate with
qcom_icc_rpm_smd_send() [1] and the remaining 37 where
qcom_icc_rpm_smd_send() fails with -ENXIO [2].
The device tree snippets that I'm using is in patch 1 of this series,
however the relevant interconnect properties for the mdp5 are:
interconnects = <&mmssnoc MNOC_MAS_GRAPHICS_3D &bimc BIMC_SLV_EBI_CH0>,
<&ocmemnoc OCMEM_VNOC_MAS_GFX3D &ocmemnoc OCMEM_SLV_OCMEM>;
interconnect-names = "mdp0-mem", "mdp1-mem";
The two interconnects have the following paths:
- mdp0-mem
- mas_graphics_3d
- mnoc_to_bimc
- bimc_to_mnoc
- slv_ebi_ch0
- mdp1-mem
- mas_v_ocmem_gfx3d
- ocmem_vnoc_to_onoc
- ocmem_noc_to_ocmem_vnoc
- slv_ocmem
ocmem_noc_to_ocmem_vnoc is the only one that is successfully activated
and the remaining fail in these two paths.
With this interconnect driver, I am able to remove a clock hack that I
had in place that set the speed of MDSS_AXI_CLK high and I'm able to use
kmscube. However, I do see a clock warning on system startup [3].
The display doesn't work for me with the downstream MSM sources so I may
have to get that working to debug this some more unless anyone has any
suggestions. I verified that the downstream msm8974 sources are using
rpm smd to setup the interconnects for the msm bus:
https://github.com/AICP/kernel_lge_hammerhead/blob/n7.1/arch/arm/mach-msm/msm_bus/msm_bus_rpm_smd.c#L153
The only difference I noticed is that that upstream uses a 32 bit field
for the 'value' field in drivers/interconnect/qcom/smd-rpm.c for
qcom_icc_rpm_smd_send(), and downstream uses a 64 bit value instead.
Changing that upstream doesn't make a difference.
Downstream msm8974 msm bus code:
https://github.com/AICP/kernel_lge_hammerhead/blob/n7.1/arch/arm/mach-msm/msm_bus/msm_bus_board_8974.c
