Christian Hewitt fdfc6997bd soc: amlogic: meson-gx-socinfo: Fix S905D3 ID for VIM3L
Chip on the board is S905D3 not S905X3:

[    0.098998] soc soc0: Amlogic Meson SM1 (S905D3) Revision 2b:c (b0:2) Detected

Change from v1: use 0xf0 mask instead of 0xf2 as advised by Neil Armstrong.

Nishka Dasgupta 49ed86f503 soc: amlogic: meson-gx-socinfo: Add of_node_put() before return
The variable np in function meson_gx_socinfo_init takes the return value
of of_find_compatible_node, which gets a node but does not put it. If
this node is not put it may cause a memory leak. Hence put np after its
usefulness has been exhausted.
Issue found with Coccinelle.

Julia Lawall fdda0a6adc meson-gx-socinfo: add missing of_node_put after of_device_is_available
Add an of_node_put when a tested device node is not available.

The semantic patch that fixes this problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>

identifier f;
local idexpression e;
expression x;
@@

e = f(...);
... when != of_node_put(e)

  ... when != of_node_put(e)

  return e;

+ of_node_put(e);
  return ...;

}

Neil Armstrong dce47aed20 soc: amlogic: gx-socinfo: Add mask for each SoC packages
When updated IDs on f842c41adc ("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.

Arnaud Patard 044d71bc6c meson-gx-socinfo: Fix package id parsing
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.
