Re: [PATCH 5.10.y-cip 00/27] Add RPCIF, SCI{F1} support to Renesas RZ/G2L SoC

Pavel Machek
 

Hi!

This patch series add support for the below:
* Adds a generic property "output-impedance-ohms"
* Pinctrl driver update to support set/get drive-strength and
output-impedance-ohms
* Driver fixes and updates for RPC-IF
* Support to SPI Multi I/O Bus controller (RPC-IF) for RZ/G2L
* Support to SCI for RZ/G2L SoC
* DTS updates for RZ/G2L SMARC

All the patches have been cherry-picked from Linux v5.17-rc2.
Testing did not uncover any kernel problems. I have applied the
patches and pushed the tree.

Best regards,
Pavel

From: Shivanand Kunijadar <Shivanand.Kunijadar@...>

The current isar-cip-core provides verification of successful swupdate
but lacks the recipe to verify swupdate-rollback feature, the below
patches provides the necessary script to verify swupdate-rollback.

Re: [PATCH 5.10.y-cip 00/27] Add RPCIF, SCI{F1} support to Renesas RZ/G2L SoC

Pavel Machek
 

Hi!

This patch series add support for the below:
* Adds a generic property "output-impedance-ohms"
* Pinctrl driver update to support set/get drive-strength and
output-impedance-ohms
* Driver fixes and updates for RPC-IF
* Support to SPI Multi I/O Bus controller (RPC-IF) for RZ/G2L
* Support to SCI for RZ/G2L SoC
* DTS updates for RZ/G2L SMARC

All the patches have been cherry-picked from Linux v5.17-rc2.
I found some minor details, but overall series looks okay. I'm
currently running tests, I can apply it if it passes and if there are
no other comments.

Best regards,
Pavel

Re: [PATCH 5.10.y-cip 16/27] memory: renesas-rpc-if: Add support for RZ/G2L

Pavel Machek
 

Hi!
commit b04cc0d912eb80d3c438b11d96ca847c3e77e8ab upstream.

SPI Multi I/O Bus Controller on RZ/G2L SoC is almost identical to
the RPC-IF interface found on R-Car Gen3 SoC's.

This patch adds a new compatible string for the RZ/G2L family so
that the timing values on RZ/G2L can be adjusted.

using 0x0 so it is clear we are not aiming for 8 digits).

Re: [PATCH 5.10.y-cip 05/27] pinctrl: renesas: rzg2l: Add helper functions to read/write pin config

Pavel Machek
 

Hi!

commit d1189991c823b50990291c8157b56fb141c47155 upstream.

Add helper functions to read/read modify write pin config.

Switch to use helper functions for pins supporting PIN_CONFIG_INPUT_ENABLE
capabilities.
Along with refactoring code, this also removes locking from the
reads. Which is okay AFAICT, but note in changelog would not hurt.

[PATCH 5.10.y-cip 23/27] serial: sh-sci: Add support to deassert/assert reset line

Lad Prabhakar
 

commit 862f72187a41008df2cce3f8e97f57070cbc7060 upstream.

On RZ/G2L SoC we need to explicitly deassert the reset line
for the device to work, use this opportunity to deassert/assert
reset line in sh-sci driver.

This patch adds support to read the "resets" property (if available)
from DT and perform deassert/assert when required.

Also, propagate the error to the caller of sci_parse_dt() instead of
returning NULL in case of failure.
