Subject: [PATCH 2/9] arm: tegra: apalis_t30: fix hdmi supply
Date: Fri, 28 Aug 2015 14:42:29 +0200

Fix HDMI supplies (both regular VDD as well as PLL ones) being switched
by the TPS65911 PMIC's GPIO6 aka EN_VDD_HDMI by introducing two new
GPIO switched fixed regulators avdd_hdmi_pll_1v8_reg and
avdd_hdmi_3v3_reg.
