reset: brcmstb: Enable reset drivers for ARCH_BCM2835

2025-08-28T14:22:41+00:00

[ Upstream commit 1d99f92f71b6b4b2eee776562c991428490f71ef ]

The BRCMSTB and BRCMSTB_RESCAL reset drivers are also
used in the BCM2712, AKA the RPi5. The RPi platforms
have typically used the ARCH_BCM2835, and the PCIe
support for this SoC can use this config which depends
on these drivers so enable building them when just that
arch option is enabled to ensure the platform works as
expected.

reset: berlin: fix OF node leak in probe() error path

[ Upstream commit 5f58a88cc91075be38cec69b7cb70aaa4ba69e8b ]

Driver is leaking OF node reference on memory allocation failure.
Acquire the OF node reference after memory allocation to fix this and
keep it simple.

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

reset: Fix crash when freeing non-existent optional resets

2024-01-05T14:12:23+00:00

[ Upstream commit 4a6756f56bcf8e64c87144a626ce53aea4899c0e ]

When obtaining one or more optional resets, non-existent resets are
stored as NULL pointers, and all related error and cleanup paths need to
take this into account.

Currently only reset_control_put() and reset_control_bulk_put()
get this right.  All of __reset_control_bulk_get(),
of_reset_control_array_get(), and reset_control_array_put() lack the
proper checking, causing NULL pointer dereferences on failure or
release.

Fix this by moving the existing check from reset_control_bulk_put() to
__reset_control_put_internal(), so it applies to all callers.
The double check in reset_control_put() doesn't hurt.

reset: imx7: Fix the iMX8MP PCIe PHY PERST support

2022-10-05T08:38:40+00:00

[ Upstream commit 051d9eb403887bb11852b7a4f744728a6a4b1b58 ]

On i.MX7/iMX8MM/iMX8MQ, the initialized default value of PERST bit(BIT3)
of SRC_PCIEPHY_RCR is 1b'1.
But i.MX8MP has one inversed default value 1b'0 of PERST bit.

And the PERST bit should be kept 1b'1 after power and clocks are stable.
So fix the i.MX8MP PCIe PHY PERST support here.
