Subject: [PATCH] pinctrl: ingenic: Fix incorrect pull up/down info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix the pull up/down info for both the JZ4760 and JZ4770 SoCs, as the
previous values sometimes contradicted what's written in the programming
manual.
Fixes: b5c23aa46537 ("pinctrl: add a pinctrl driver for the Ingenic jz47xx SoCs")
