2020-01-27soc: amlogic: gx-socinfo: Add mask for each SoC packagesNeil Armstrong1-15/+17
[ Upstream commit dce47aed20c7de3ee2011b7a63e67f08e9dcfb5e ] When updated IDs on f842c41adc04 ("amlogic: meson-gx-socinfo: Update soc ids") we introduced packages ids using the full 8bit value, but in the function socinfo_to_package_id() the id was filtered with the 0xf0 mask. While the 0xf0 mask is valid for most board, it filters out the lower 4 bits which encodes some characteristics of the chip. This patch moves the mask into the meson_gx_package_id table to be applied on each package name independently and add the correct mask for some specific entries. An example is the S905, in the vendor code the S905 is package_id different from 0x20, and S905M is exactly 0x20. Another example are the The Wetek Hub & Play2 boards using a S905-H variant, which is the S905 SoC with some licence bits enabled. These licence bits are encoded in the lower 4bits, so to detect the -H variant, we must detect the id == 0x3 with the 0xf mask.

2017-12-01meson-gx-socinfo: Fix package id parsingArnaud Patard1-2/+2
I've noticed the following message while booting a S905X based board: soc soc0: Amlogic Meson GXL (S905D) Revision 21:82 (b:2) Detected The S905D string is obviously wrong. The vendor code does: ... ver = (readl(assist_hw_rev) >> 8) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_MINOR] = ver; ver = (readl(assist_hw_rev) >> 16) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_PACK] = ver; ... while the current code does: ... ... This means that the current mainline code has package id and minor version reversed.

2017-07-28soc: Add Amlogic SoC Information driverNeil Armstrong1-0/+177
Amlogic SoCs have a SoC information register for SoC type, package type and revision information. This patchs adds support for this register decoding and exposing with the SoC bus infrastructure.
