Subject: [PATCH] arm64: dts: ti: k3-am62x-sk-common: Add bootph-all for I2C1 instance pinmux
Date: Fri, 14 Jun 2024 18:05:32 +0530 [thread overview]
Message-ID: <20240614123532.203983-1-devarsht@ti.com> (raw)
I2C1 controller controls io-expander which provides power to voltage
regulator vdd_mmc1 for MMC SD using a gpio line.
Add bootph-all to the pinmux node for this instance, as this is used during
SPL stage too by the bootloader while using SD boot mode as without this
the SD boot mode fails with below error when using this device-tree in
u-boot:
"Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured
Timed out in wait_for_event: status=0000
Check if pads/pull-ups of bus are properly configured
"
