[PATCH v2 0/2] imx8mp-frdm: Enhance code readability

[Daniel Baluta]

Enhance the readability of IOMUXC_SW_PAD_CTL_PAD configuration by using
symbolic macros instead of magic values.

First patch makes MX8MP_I2C_DEFAULT independent of DS so it can be
re-used in multiple places.

Second patch makes uses on the macros introduce with:
31ff1060175c458 ("arm64: dts: imx8mp: Add pinctrl config definitions")
in order to make code easier to read and understand.

Changes since v1:
   * v1: https://lore.kernel.org/imx/20260227130242.1702329-1-daniel.baluta@nxp.com/
   * remove RFC tag as seems v1 got positive feedback
   * add R-b tag from Maud for patch 1/2
   * update commit message for patch 2/2 as suggested by Frank
   * Use existing macro instead of introducing MX8MP_NAND_DATA_DEFAULT
     as suggested by Maud and Frank

[PATCH v2 1/2] arm64: dts: imx8mp: Make MX8MP_I2C_DEFAULT independent on drive strength

[Daniel Baluta]

Currently MX8MP_I2C_DEFAULT macro includes a fixed drive
strength (MX8MP_DSE_X6) thus limiting its use to only I2C
pins that require X6 drive.

There are many pinctrl configurations for I2C that use different
drive strength while still using the common I2C default configurations
(pull-up, Schmitt input, pull enable, SION).

So make the MX8MP_I2C_DEFAULT macro more flexible and reusable by removing
DSE_X6 drive strength from it's definition but add or it in all places
it is necessary.

[PATCH v2 2/2] arm64: dts: imx8mp-frdm: Use symbolic macros for IOMUXC_SW_PAD_CTL_PAD

[Daniel Baluta]

Currently, in order to configure IOMUXC_SW_PAD_CTL_PAD a magic raw value
is written in this register. This makes code not obvious to read and
modify.

Use symbolic macros instead of the magic values to improve code
readability.
