2022-03-24T01:23:13+00:00

Pull ARM driver updates from Arnd Bergmann:
 "There are a few separately maintained driver subsystems that we merge
  through the SoC tree, notable changes are:

   - Memory controller updates, mainly for Tegra and Mediatek SoCs, and
     clarifications for the memory controller DT bindings

   - SCMI firmware interface updates, in particular a new transport
     based on OPTEE and support for atomic operations.

   - Cleanups to the TEE subsystem, refactoring its memory management

  For SoC specific drivers without a separate subsystem, changes include

   - Smaller updates and fixes for TI, AT91/SAMA5, Qualcomm and NXP
     Layerscape SoCs.

   - Driver support for Microchip SAMA5D29, Tesla FSD, Renesas RZ/G2L,
     and Qualcomm SM8450.

   - Better power management on Mediatek MT81xx, NXP i.MX8MQ and older
     NVIDIA Tegra chips"

Memory controller drivers for v5.18, part two

1. TI: Two fixes for TI EMIF driver for quite old error path issues (so
   for unlikely scenarios).
2. Renesas: Document RZ/V2L SoC in bindings.

memory: emif: check the pointer temp in get_device_details()

2022-03-04T08:08:27+00:00

The pointer temp is allocated by devm_kzalloc(), so it should be
checked for error handling.

memory: emif: Add check for setup_interrupts

2022-03-04T08:07:42+00:00

As the potential failure of the devm_request_threaded_irq(),
it should be better to check the return value of the
setup_interrupts() and return error if fails.

memory: Update of_memory lpddr2 revision-id binding

2022-02-25T12:36:49+00:00

This patch updates the code parsing the "jedec,lpddr2" device tree
binding to use the new `revision-id` property instead of the deprecated
`revision-id1` and `revision-id2` properties if available.

memory: of: parse max-freq property

2022-02-09T14:34:42+00:00

Passing the memory timings maximum frequency as an unit address was
a workaround and instead 'max-freq' is preferred.  Look for 'max-freq'
first and then fallback to 'reg'.
