Subject: phy: phy-rockchip-samsung-hdptx: Don't request RST_PHY/RST_ROPLL/RST_LCPLL
X-Git-Tag: microblaze-v6.16~515^2~19
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=f2dbca169790ea1e436ffdd9ef37d7c3a4401c46;p=linux-2.6-microblaze.git

phy: phy-rockchip-samsung-hdptx: Don't request RST_PHY/RST_ROPLL/RST_LCPLL

RST_PHY/RST_ROPLL/RST_LCPLL are used for debug only on rk3588,
and they are not exported on rk3576, no need to request it in
driver.
