[PATCH AUTOSEL 6.12 119/486] mfd: tps65219: Remove TPS65219_REG_TI_DEV_ID check

[Sasha Levin]

From: Shree Ramamoorthy <s-ramamoorthy@ti.com>

[ Upstream commit 76b58d5111fdcffce615beb71520bc7a6f1742c9 ]

The chipid macro/variable and regmap_read function call is not needed
because the TPS65219_REG_TI_DEV_ID register value is not a consistent value
across TPS65219 PMIC config versions. Reading from the DEV_ID register
without a consistent value to compare it to isn't useful. There isn't a
way to verify the match data ID is the same ID read from the DEV_ID device
register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM
configurations.

For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID
register. However, there are other error checks in place within probe()
that apply to both PMICs rather than keeping this isolated check for one
PMIC.

[PATCH AUTOSEL 6.12 206/486] net: ethernet: ti: cpsw_new: populate netdev of_node

[Sasha Levin]

From: Alexander Sverdlin <alexander.sverdlin@siemens.com>

[ Upstream commit 7ff1c88fc89688c27f773ba956f65f0c11367269 ]

So that of_find_net_device_by_node() can find CPSW ports and other DSA
switches can be stacked downstream. Tested in conjunction with KSZ8873.
