6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jared McArthur <j-mcarthur@xxxxxx>
[ Upstream commit b7af8b4acb3e08c710cd48f098ce8cd07cf43a1e ]
Commit 0d0a0b441346 ("arm64: dts: ti: k3-j7200: fix main pinmux
range") split the main_pmx0 into two nodes: main_pmx0 and main_pmx1
due to a non-addressable region, but incorrectly represented the
ranges. As a result, the memory map for the pinctrl is incorrect. Fix
this by introducing the correct ranges.
The ranges are taken from the J7200 TRM [1] (Table 5-695. CTRL_MMR0
Registers).
Padconfig starting addresses and ranges:
- 0 to 66: 0x11c000, 0x10c
- 68: 0x11c110, 0x004
- 71 to 73: 0x11c11c, 0x00c
- 89 to 90: 0x11c164, 0x008
The datasheet [2] doesn't contain PADCONFIG63 (Table 6-106. Pin
Multiplexing), but the pin is necessary for enabling the MMC1 CLKLP
pad loopback and should be included in the pinmux register map.
Due to the change in pinmux node addresses, change the pinmux node for
the USB0_DRVVBUS pin to main_pmx2. The offset has not changed since the
new main_pmx2 node has the same base address and range as the original
main_pmx1 node. All other pinmuxing done within J7200 dts or dtso files
only uses main_pmx0 which has not changed.
