arm: dts: armada8040: Fix CP0 eMMC/SDIO support

2021-09-29T05:13:27+00:00

During the migration to a single DTSI for the CP110-s specific pinctrl compatibles were moved to the SoC DTSI as CP0 and CP1 have some specifics. Namely, CP0 eMMC/SDIO support depends on the mvebu-pinctrl driver setting the BIT(0) in eMMC PHY IO Control 0 Register to 0 in order for the connect the eMMC/SDIO PHY to the controller and not use it as a MPP pin multiplexor. So, the mvebu-pinctrl driver check specifically for the "marvell,armada-8k-cpm-pinctrl" compatible to clear the that bit. Issue is that compatibles in the 8040 DTSI were set to "marvell,8k-cpm-pinctrl" for CP0 and "marvell,8k-cps-pinctrl" for the CP1. This is obviously incorrect as the pinctrl driver does not know about these. So fix the regression by applying correct compatibles to the DTSI. Regression found and tested on the Puzzle M801 board.

imx: imx7d-sdb: fix ethernet, sync .dts with linux

2021-09-28T16:03:21+00:00

Commit 0d52bab46 (mx7dsabre: Enable DM_ETH) changed these flags from 0 (aka GPIO_ACTIVE_HIGH) to GPIO_ACTIVE_LOW. It claimed to "Also sync device tree with v5.5-rc1", but in the linux tree, these gpios have always been GPIO_ACTIVE_HIGH ever since this node was introduced around v4.13 (linux commit 184f39b5). I'm guessing that the reason for the GPIO_ACTIVE_LOW was to work around the behaviour of the soft-spi driver back then, which effectively defaulted to spi-mode 3 and not 0. That was arguably a bug in the soft-spi driver, which then got fixed in 0e146993bb3 (spi: add support for all spi modes with soft spi), but that commit then broke ethernet on this board. Fix it by setting the gpios as active high, which as a bonus actually brings us in sync with the .dts in the linux source tree. Without this, one gets Net: Could not get PHY for FEC0: addr 0 No ethernet found. With this, ethernet (at least ping and tftp) works as expected from the U-Boot shell.

arm: dts: stm32mp1: use ssbl partition name for U-Boot

Continue to use the "ssbl" name for GPT partition of secondary boot stage = U-Boot for basic boot with SPL to avoid to disturb existing user. The "fip" partition name is only used for TFA_BOOT with FIP, it is a TF-A BL2 requirement; it the default configuration for STMicroelectronics boards.

As per Device Tree Specification [1], the status parameter of nodes can be "okay", "disabled", etc. "ok" is not a valid parameter. U-boot Driver Model does not recognize status="ok" either and treats the node as disabled.
