+Subject: pinctrl: sh-pfc: Do not unconditionally support PIN_CONFIG_BIAS_DISABLE
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
+
+commit 5d7400c4acbf7fe633a976a89ee845f7333de3e4 upstream.
+
+Always stating PIN_CONFIG_BIAS_DISABLE is supported gives untrue output
+when examining /sys/kernel/debug/pinctrl/e6060000.pfc/pinconf-pins if
+the operation get_bias() is implemented but the pin is not handled by
+the get_bias() implementation. In that case the output will state that
+"input bias disabled" indicating that this pin has bias control
+support.
+
+Make support for PIN_CONFIG_BIAS_DISABLE depend on that the pin either
+supports SH_PFC_PIN_CFG_PULL_UP or SH_PFC_PIN_CFG_PULL_DOWN. This also
+solves the issue where SoC specific implementations print error messages
+if their particular implementation of {set,get}_bias() is called with a
+pin it does not know about.
