[PATCH v2 0/2] Add USB support for AM62D2

[PATCH v2 0/2] Add USB support for AM62D2

[Paresh Bhagat]

This patch series introduces following changes:

* Patch 1 fixes the register length in main_pmx/padconfig for AM62D
 and AM62A. This also fixes "i2c 0-003f: deferred probe pending".

* Patch 2 enables USB support for AM62D2-EVM by adding pinmux and device
 tree nodes.

Change Log:

	v1->v2:
		- Added fixes and Cc tag for Patch 1.
		- Dropped two patches for OPP (applied).

[PATCH v2 1/2] arm64: dts: ti: k3-am62a-main: Fix pinctrl properties

[Paresh Bhagat]

From: Vibhore Vardhan <vibhore@ti.com>

Correct reg length to match end address - start address for main
PADCFG registers. The last physical address for the main pad
configuration registers (MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG150) is
0x000f4258. Adding 4 bytes gives 0x000f425c, so the size in device
tree should be defined as 0x25c instead of 0x2ac.

[PATCH v2 2/2] arm64: dts: ti: k3-am62d2-evm: Enable USB support

[Paresh Bhagat]

Add pinmux configuration for USB1 interface and enable the node for
functionality. Also enable data transfer on USB0, on existing power
delivery configuration.

nitpick: s/reg/register

I assume that you are implying "end address - start address" as
subtracting the "start address" from the "end address" to get the
length. This description might not be required given that you are
stating the 'last physical address for the main pad configuration
registers' below. You might rephrase it to indicate that the main pad
configuration register region starts with the
MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG0 register having the address of
0x000f4000 and the region ends with the
MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG150 register having the address of
0x000f4258, as a result of which, the length of the region is 0x25c
instead of 0x2ac.
