[PATCH v5 1/4] mtd: spi-nor-ids: Add XMC XM25QH128C

[Fabio Estevam]

From: Fabio Estevam <festevam@nabladev.com>

Add the JEDEC ID for the XMC XM25QH128C SPI NOR flash.

This is a 128Mbit device using 64KiB sectors and supporting 4KiB
erase, dual read and quad read, matching the other XM25QH128 variants.

[PATCH v5 2/4] rockchip: rk3399: Remove ROC-PC regulator overrides

[Fabio Estevam]

From: Fabio Estevam <festevam@nabladev.com>

The upstream devicetree already describes dc_12v as the output of the
MP8859 regulator and drives the USB hub reset through the vcc5v0_host
regulator pinctrl state.

Remove the legacy fixed-regulator overrides and rely on the upstream
regulator descriptions.

[PATCH v5 3/4] rockchip: rk3399: Add ROC-PC-PLUS board detection

[Fabio Estevam]

From: Fabio Estevam <festevam@nabladev.com>

The ROC-RK3399-PC has an MP8859 regulator on I2C7 at address 0x66,
while the ROC-RK3399-PC-PLUS does not. Probe for the regulator in SPL
and use the result to select the matching devicetree from the U-Boot
FIT. Fall back to the original board if the I2C bus cannot be probed.

Build both devicetrees from the existing roc-pc-rk3399_defconfig and
enable the XMC SPI NOR driver used by the Plus variant. Set fdtfile
from the selected U-Boot devicetree so the matching Linux devicetree
is used as well.

[PATCH v5 4/4] rockchip: roc-pc-rk3399: Enable redundant environment

[Fabio Estevam]

From: Fabio Estevam <festevam@nabladev.com>

Keep the primary U-Boot environment at its existing 0x3f8000 offset and
use the preceding 32 KiB region at 0x3f0000 for the redundant copy.

Both copies are aligned to the 4 KiB erase size and together occupy
0x3f0000 through 0x3fffff. Redundancy protects the environment against
power loss or an interrupted update.

Between v4 and v5, the exclamation point now inverts the result of 
dm_i2c_probe and I believe this is incorrect.

dm_i2c_probe returns 0 if a chip was found, -ve otherwise. The 
ROC-RK3399-PC-PLUS does NOT have this chip, therefore is_roc_pc_plus() 
should return false (0) when the chip is NOT detected, meaning we should 
NOT invert dm_i2c_probe(). Is this correct?

Cheers,
Quentin
