2023-06-06T18:50:52+00:00

This patch fixes the error checking in wkup_m3_ipc.c in
debugfs_create_dir. The correct way to check if an error occurred
is 'IS_ERR' inline function.

soc: ti: pruss: Add helper functions to set GPI mode, MII_RT_event and XFR

2023-05-17T14:15:40+00:00

The PRUSS CFG module is represented as a syscon node and is currently
managed by the PRUSS platform driver. Add easy accessor functions to set
GPI mode, MII_RT event enable/disable and XFR (XIN XOUT) enable/disable
to enable the PRUSS Ethernet usecase. These functions reuse the generic
pruss_cfg_update() API function.

soc: ti: pruss: Add pruss_cfg_read()/update(), pruss_cfg_get_gpmux()/set_gpmux() APIs

2023-05-17T14:15:39+00:00

Add two new generic API pruss_cfg_read() and pruss_cfg_update() to
the PRUSS platform driver to read and program respectively a register
within the PRUSS CFG sub-module represented by a syscon driver. These
APIs are internal to PRUSS driver.

Add two new helper functions pruss_cfg_get_gpmux() & pruss_cfg_set_gpmux()
to get and set the GP MUX mode for programming the PRUSS internal wrapper
mux functionality as needed by usecases.

Various useful registers and macros for certain register bit-fields and
their values have also been added.

soc: ti: pruss: Add pruss_{request,release}_mem_region() API

2023-05-17T14:15:39+00:00

Add two new API - pruss_request_mem_region() & pruss_release_mem_region(),
to the PRUSS platform driver to allow client drivers to acquire and release
the common memory resources present within a PRU-ICSS subsystem. This
allows the client drivers to directly manipulate the respective memories,
as per their design contract with the associated firmware.

soc: ti: pruss: Add pruss_get()/put() API

2023-05-17T14:15:39+00:00

Add two new get and put API, pruss_get() and pruss_put() to the
PRUSS platform driver to allow client drivers to request a handle
to a PRUSS device. This handle will be used by client drivers to
request various operations of the PRUSS platform driver through
additional API that will be added in the following patches.

The pruss_get() function returns the pruss handle corresponding
to a PRUSS device referenced by a PRU remoteproc instance. The
pruss_put() is the complimentary function to pruss_get().

soc: ti: pruss: Avoid cast to incompatible function type

2023-05-17T14:13:05+00:00

Rather than casting clk_unregister_mux to an incompatible function
type provide a trivial wrapper with the correct signature for the
use-case.

Reported by clang-16 with W=1:

 drivers/soc/ti/pruss.c:158:38: error: cast from 'void (*)(struct clk *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
         ret = devm_add_action_or_reset(dev, (void(*)(void *))clk_unregister_mux,

No functional change intended.
Compile tested only.

soc: ti: smartreflex: Simplify getting the opam_sr pointer

2023-04-14T16:03:06+00:00

The probe function stores the sr_info pointer using
platform_set_drvdata(). Use the corresponding platform_get_drvdata() to
retrieve that pointer in the remove and shutdown functions.

This simplifies these functions and makes error handling unnecessary.
This is a good thing as at least for .remove() returning an error code
doesn't have the desired effect.

This is a preparation for making platform remove callbacks return void.
