This adds the APB bus on Meson8 and Meson8b as well as the APB2 bus on Meson6. This is preparation work for adding the Mali GPU which is located on theses busses. Meson6 seems to have it's APB at 0xc8000000 instead of 0xd0000000. The region at 0xd0000000 is called APB2 or A9_APB and it has a different size (256k) compared to Meson8 and Meson8b (2M). Addresses and sizes are taken from the Amlogic 3.10 kernel sources: - Meson6: [0] - Meson8: [1] - Meson8b: [2] Changes since v1 at [3]: - re-send the patches but this time don't include the old patches which still had a typo in the patch description (ABP vs APB) [0] https://github.com/endlessm/linux-meson/blob/cd4096c3ff4eb5b8a8a5581bb46508601c5470dc/arch/arm/mach-meson6/include/mach/io.h#L61 [1] https://github.com/endlessm/linux-meson/blob/cd4096c3ff4eb5b8a8a5581bb46508601c5470dc/arch/arm/mach-meson8/include/mach/io.h#L53 [2] https://github.com/endlessm/linux-meson/blob/cd4096c3ff4eb5b8a8a5581bb46508601c5470dc/arch/arm/mach-meson8b/include/mach/io.h#L53 [3] http://lists.infradead.org/pipermail/linux-amlogic/2018-December/009424.html Martin Blumenstingl (3): ARM: dts: meson6: add the APB2 bus ARM: dts: meson8: add the APB bus ARM: dts: meson8b: add the APB bus arch/arm/boot/dts/meson6.dtsi | 8 ++++++++ arch/arm/boot/dts/meson8.dtsi | 8 ++++++++ arch/arm/boot/dts/meson8b.dtsi | 8 ++++++++ 3 files changed, 24 insertions(+) -- 2.19.2
