Subject: [PATCH v6 04/15] platform_data: Add linux/platform_data/tps68470.h file
Date: Thu, 25 Nov 2021 17:54:01 +0100	[thread overview]
Message-ID: <20211125165412.535063-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20211125165412.535063-1-hdegoede@redhat.com>

The clk and regulator frameworks expect clk/regulator consumer-devices
to have info about the consumed clks/regulators described in the device's
fw_node.

To work around cases where this info is not present in the firmware tables,
which is often the case on x86/ACPI devices, both frameworks allow the
provider-driver to attach info about consumers to the provider-device
during probe/registration of the provider device.

The TI TPS68470 PMIC is used x86/ACPI devices with the consumer-info
missing from the ACPI tables. Thus the tps68470-clk and tps68470-regulator
drivers must provide the consumer-info at probe time.

Define tps68470_clk_platform_data and tps68470_regulator_platform_data
structs to allow the x86 platform code to pass the necessary consumer info
to these drivers.
