[PATCH v4 01/15] arm64: dts: freescale: imx93-phycore-som: Add PMIC support

[Primoz Fiser]

PMIC driver for PCA9451A used on phyCORE-i.MX93 SOM is available since
commit 5edeb7d31262 ("regulator: pca9450: add pca9451a support"). Add
support for it in the SOM device-tree.

[PATCH v4 03/15] arm64: dts: freescale: imx93-phycore-som: Disable LED pull-up

[Primoz Fiser]

There is already an external pull-down resistor on the LED output line.
It makes no sense to have both pull-down and pull-up resistors enabled
at the same time. Thus disable the internal pull-up.

[PATCH v4 04/15] arm64: dts: freescale: imx93-phycore-som: Enhance eMMC pinctrl

[Primoz Fiser]

Improve eMMC on phyCORE-i.MX93 SOM by adding 100MHz and 200MHz pinctrl
modes. This enables to use eMMC at enhanced data rates (e.g. HS400).

While at it, apply a workaround for the i.MX93 chip errata ERR052021.

[PATCH v4 05/15] arm64: dts: freescale: imx93-phycore-som: Add eMMC no-1-8-v by default

[Primoz Fiser]

The phyCORE-i.MX93 SoM comes in two variants, one with VDD_IO set to
3.3V and the other variant to 1.8V. The 3.3V variant can only support
DDR52 mode, while 1.8V variant is capable of HS400ES eMMC mode. The
information about VDD_IO option is encoded in the SoM's EEPROM. EEPROM
is read in the bootloader and bootloader clears the "no-1-8-v" flag in
case of 1.8V SoM variant is detected. Thus add property 'no-1-8-v' by
default to usdhc1 (eMMC) node and let bootloader handle the flag. In
case EEPROM is erased or read-out fails, flag "no-1-8-v" also ensures
fall-back compatibility with both SoM variants.

[PATCH v4 08/15] arm64: dts: freescale: imx93-phyboard-segin: Fix SD-card pinctrl

[Primoz Fiser]

Until now, all usdhc2 (SD-card) pinctrl labels pointed to one pinctrl
group "usdhc2grp" which was overwritten twice by the 100 and 200 MHz
modes. Fix this by using unique pinctrl names.

Additionally, adjust MX93_PAD_SD2_CLK__USDHC2_CLK pad drive-strength
according to values obtained by measurements from the PHYTEC hardware
department to improve signal integrity.

[PATCH v4 09/15] arm64: dts: freescale: imx93-phyboard-segin: Set CMD/DATA SION bit to fix ERR052021

[Primoz Fiser]

Implement fix for i.MX 93 silicon errata ERR052021.

ERR052021 uSDHC: Sometimes uSDHC does not work under VDD_SOC low
		 drive mode and nominal mode
Description:
  uSDHC PADs have one integration issue.
  When CMD/DATA lines direction change from output to input, uSDHC
  controller begin sampling, the integration issue will make input
  enable signal from uSDHC propagated to the PAD with a long delay,
  thus the new input value on the pad comes to uSDHC lately. The
  uSDHC sampled the old input value and the sampling result is wrong.

Workaround:
  Set uSDHC CMD/DATA PADs iomux register SION bit to 1, then PADs will
  propagate input to uSDHC with no delay, so correct value is sampled.

This issue will wrongly trigger the start bit when sample the USDHC
command response, cause the USDHC trigger command CRC/index/endbit
error, which will finally impact the tuning pass window, especially
will impact the standard tuning logic, and can't find a correct delay
cell to get the best timing.

Based on commit bb89601282fc ("arm64: dts: imx93-11x11-evk: set SION for
cmd and data pad of USDHC").

[PATCH v4 11/15] arm64: dts: freescale: imx93-phyboard-segin: Add CAN support

[Primoz Fiser]

Add support for CAN networking on phyBOARD-Segin-i.MX93 via the flexcan1
interface. The CAN PHY chip SN65HVD234D used on the board is compatible
with the TCAN1043 driver using the generic "can-transceiver-phy" and is
capable of up to 1Mbps data rate.
