soc: amlogic: meson-gx-socinfo: Fix S905X3 and S905D3 ID's

2020-06-29T23:00:53+00:00

Correct the SoC revision and package bits/mask values for S905D3/X3 to detect a wider range of observed SoC IDs, and tweak sort order for A311D/S922X. S905X3 05 0000 0101 (SEI610 initial devices) S905X3 10 0001 0000 (ODROID-C4 and recent Android boxes) S905X3 50 0101 0000 (SEI610 later revisions) S905D3 04 0000 0100 (VIM3L devices in kernelci) S905D3 b0 1011 0000 (VIM3L initial production) Fixes commit c9cc9bec36d0 ("soc: amlogic: meson-gx-socinfo: Add SM1 and S905X3 IDs") Suggested-by: Neil Armstrong Signed-off-by: Christian Hewitt Signed-off-by: Kevin Hilman Acked-by: Neil Armstrong Link: https://lore.kernel.org/r/20200609081318.28023-1-christianshewitt@gmail.com

soc: amlogic: meson-ee-pwrc: add support for the Meson GX SoCs

2020-05-19T23:02:14+00:00

Add support for the Meson GX SoCs to the meson-ee-pwrc driver. The power domains on the GX SoCs are very similar to G12A. The only known differences so far are: - The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the VPU power-domain) - The GX SoCs have an additional reset line called "dvin" Signed-off-by: Martin Blumenstingl Signed-off-by: Kevin Hilman Reviewed-by: Neil Armstrong Link: https://lore.kernel.org/r/20200515204709.1505498-5-martin.blumenstingl@googlemail.com

soc: amlogic: meson-ee-pwrc: add support for Meson8/Meson8b/Meson8m2

2020-05-19T23:02:14+00:00

This adds support for the power domains on Meson8/Meson8b/Meson8m2. Meson8 doesn't use any reset lines while Meson8b and Meson8m2 use the same set of reset lines (which is different from the newer SoCs). Add dedicated compatible strings for Meson8, Meson8b and Meson8m2 to support these differences. Notable differences between Meson8 and G12A are: - there is no HHI_VPU_MEM_PD_REG2 on the 32-bit SoCs - the Meson8b datasheet describes an "audio DSP memory" power domain which is used for the hardware audio decoder - the "amlogic,ao-sysctrl" only includes the power management related registers on the 32-bit SoCs, meaning the for example the AO_RTI_GEN_PWR_SLEEP0 register is at offset (0x2 << 2) rather than (0x3a << 2). As result of this (0x38 << 2) is subtracted from the register offsets, which is the start of the power management related registers.
