Subject: [PATCH v2 1/3] dt-bindings: pci: ti,j721e: Fix "ti,syscon-pcie-ctrl" to take argument
Date: Fri, 4 Dec 2020 13:21:15 +0530	[thread overview]
Message-ID: <20201204075117.10430-2-kishon@ti.com> (raw)
In-Reply-To: <20201204075117.10430-1-kishon@ti.com>

Fix binding documentation of "ti,syscon-pcie-ctrl" to take phandle with
argument. The argument is the register offset within "syscon" used to
configure PCIe controller. This change is as discussed in [1]

[1] -> http://lore.kernel.org/r/CAL_JsqKiUcO76bo1GoepWM1TusJWoty_BRy2hFSgtEVMqtrvvQ@mail.gmail.com

Fixes: 431b53b81cdc ("dt-bindings: PCI: Add host mode dt-bindings for TI's J721E SoC")
Fixes: 45b39e928966 ("dt-bindings: PCI: Add EP mode dt-bindings for TI's J721E SoC")
