Subject: [PATCH V4 1/3] arm64: dts: ti: k3-j721s2: fix main pinmux range
From: Sinthu Raja <sinthu.raja@...com>
PADCONFIG_64 register is non-addressable in the existing main pinmux
region. So only valid registers are included and main pinmux region
is split into two ranges as follows. Also update references to old
nodes with new ones as per the newly split main_pmx* node.
main_pmx0 -> 64 pins (WKUP_PADCONFIG 0 - 63)
main_pmx1 -> 7 pins (WKUP_PADCONFIG 65 - 71)
Fixes: b8545f9d3a54 ("arm64: dts: ti: Add initial support for J721S2 SoC")
