Subject: [PATCH v3 8/8] dt-bindings: pinctrl: samsung: deprecate header with register constants
Date: Sun,  5 Jun 2022 18:05:08 +0200	[thread overview]
Message-ID: <20220605160508.134075-9-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20220605160508.134075-1-krzysztof.kozlowski@linaro.org>

For convenience (less code duplication, some meaning added to raw
number), the pin controller pin configuration register values
were defined in the bindings header.  These are not some IDs or other
abstraction layer but raw numbers used in the registers

These constants do not fit the purpose of bindings.  They do not provide
any abstraction, any hardware and driver independent ID.  With minor
exceptions, the Linux drivers actually do not use the bindings header at
all.

All of the constants were moved already to headers local to DTS
(residing in DTS directory) and to Samsung pinctrl driver (where
applicable), so remove any references to the bindings header and add a
warning tha tit is deprecated.
