ARM: dts: nomadik: Fix up interrupt controller node names

2021-08-26T12:36:44+00:00

[ Upstream commit 47091f473b364c98207c4def197a0ae386fc9af1 ]

Once the new schema interrupt-controller/arm,vic.yaml is added, we get
the below warnings:

	arch/arm/boot/dts/ste-nomadik-nhk15.dt.yaml:
	intc@10140000: $nodename:0: 'intc@10140000' does not match
	'^interrupt-controller(@[0-9a-f,]+)*$'

Fix the node names for the interrupt controller to conform
to the standard node name interrupt-controller@..

ARM: dts: am43x-epos-evm: Reduce i2c0 bus speed for tps65218

2021-08-26T12:36:44+00:00

[ Upstream commit 20a6b3fd8e2e2c063b25fbf2ee74d86b898e5087 ]

Based on the latest timing specifications for the TPS65218 from the data
sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
from November 2014, we must change the i2c bus speed to better fit within
the minimum high SCL time required for proper i2c transfer.

When running at 400khz, measurements show that SCL spends
0.8125 uS/1.666 uS high/low which violates the requirement for minimum
high period of SCL provided in datasheet Table 7.6 which is 1 uS.
Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.

Without this patch occasionally a voltage set operation from the kernel
will appear to have worked but the actual voltage reflected on the PMIC
will not have updated, causing problems especially with cpufreq that may
update to a higher OPP without actually raising the voltage on DCDC2,
leading to a hang.

omap5-board-common: remove not physically existing vdds_1v8_main fixed-regulator

2021-08-12T11:19:39+00:00

[ Upstream commit c68ef4ad180e09805fa46965d15e1dfadf09ffa5 ]

This device tree include file describes a fixed-regulator
connecting smps7_reg output (1.8V) to some 1.8V rail and
consumers (vdds_1v8_main).

This regulator does not physically exist.

I assume it was introduced as a wrapper around smps7_reg
to provide a speaking signal name "vdds_1v8_main" as label.

This fixed-regulator without real function was not an issue
in driver code until

  Commit 98e48cd9283d ("regulator: core: resolve supply for boot-on/always-on regulators")

introduced a new check for regulator initialization which
makes Palmas regulator registration fail:

[    5.407712] ldo1: supplied by vsys_cobra
[    5.412748] ldo2: supplied by vsys_cobra
[    5.417603] palmas-pmic 48070000.i2c:palmas@48:palmas_pmic: failed to register 48070000.i2c:palmas@48:palmas_pmic regulator

The reason is that the supply-chain of regulators is too
long and goes from ldo3 through the virtual vdds_1v8_main
regulator and then back to smps7. This adds a cross-dependency
of probing Palmas regulators and the fixed-regulator which
leads to probe deferral by the new check and is no longer
resolved.

Since we do not control what device tree files including this
one reference (either &vdds_1v8_main or &smps7_reg or both)
we keep both labels for smps7 for compatibility.

ARM: dts: colibri-imx6ull: limit SDIO clock to 25MHz

2021-08-12T11:19:38+00:00

[ Upstream commit 828db68f4ff1ab6982a36a56522b585160dc8c8e ]

NXP and AzureWave don't recommend using SDIO bus mode 3.3V@50MHz due
to noise affecting the wireless throughput. Colibri iMX6ULL uses only
3.3V signaling for Wi-Fi module AW-CM276NF.

Limit the SDIO Clock on Colibri iMX6ULL to 25MHz.
