Subject: [PATCH net-next v4 11/17] net: dsa: microchip: ksz9477: remove MII_CTRL1000 check from ksz9477_w_phy()
Date: Fri, 26 Aug 2022 12:56:28 +0200 [thread overview]
Message-ID: <20220826105634.3855578-12-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220826105634.3855578-1-o.rempel@pengutronix.de>
The reason why PHYlib may access MII_CTRL1000 on the chip without GBit
support is only if chip provides wrong information about extended caps
register. This issue is now handled by ksz9477_r_phy_quirks()
With proper regmap_ranges provided for all chips we will be able to
catch this kind of bugs any way. So, remove this sanity check.
