[PATCH 1/2] arm64: dts: ti: k3-j7200: Fix physical address of pin

[Udit Kumar]

Fixes: 9ae21ac445e9 ("arm64: dts: ti: k3-j7200: Fix wakeup pinmux range")

wkup_pmx splits into multiple regions. Like

    wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12)
    wkup_pmx1 -> 2 pins (WKUP_PADCONFIG 14 - 15)
    wkup_pmx2 -> 59 pins (WKUP_PADCONFIG 26 - 84)
    wkup_pmx3 -> 8 pins (WKUP_PADCONFIG 93 - 100)

With this split, pin offset needs to be adjusted to
match with new pmx for all pins above wkup_pmx0.

Example a pin under wkup_pmx1 should start from 0 instead of
old offset(0x38 WKUP_PADCONFIG 14 offset)

[PATCH 2/2] arm64: dts: ti: k3-j7200-common-proc-board: Enable I2C

[Udit Kumar]

All I2C nodes were disabled in SOC dts file and in board
dts needed nodes were enabled.
This patch enables wkup_i2c0 node in board dts file.

Fixes: a9ed915cd55c ("arm64: dts: ti: k3-j7200: Enable I2C nodes at the board level")

This should'nt be fixing the commit - the commit is correct in the sense
that if the board does'nt describe a node with pinmux, the i2c is'nt
functional in the first place.

How about the pinmux? speed? what peripheral is on the wakeup i2c?

	Do we have an eeprom or something here?

well, how i look at before this patch each i2c was functional.

this fix is making needed i2c as disabled, however this fix is correct

I am ok to remove Fixes

This got eeprom and PMIC,

eeprom read is ok with pin mux and speed.

if you want to specify, let me know

git apply on original patch didn't worked , so i applied and committed.

will fix in patch itself before posting, Keerthi as author

yes, you must specify eeprom at least. I understand pmic is in

not the baseboard dtsi.
